Derailed may refer to: Derailment , in which a rail vehicle leaves the tracks on which it is travelling Films [ edit ] The English language title for the 1942 Danish film Afsporet Derailed (2002 film) , a 2002 action movie directed by and starring Jean-Claude Van Damme Derailed (2005 film) ,
312-895: A strict constructionist view of the Constitution , while Clay, Calhoun, and Adams embraced federally funded internal improvements , high tariffs , and the Second Bank of the United States , which was also known as the national bank. Because the Federalist Party had all but collapsed after the War of 1812, all the major presidential candidates were members of the Democratic-Republican Party. Adams felt that his own election as president would vindicate his father, while also allowing him to pursue an ambitious domestic policy. Though he lacked
468-419: A " Corrupt bargain " whereby Adams promised Clay the position of Secretary of State in return for Clay's support. Adams was inaugurated on March 4, 1825, becoming the first son of a former United States president to himself become president, a feat only repeated 176 years later by George W. Bush , son of George H. W. Bush . As Adams took the oath of office , he departed from tradition by placing his hand on
624-462: A "run-in") may result in a vehicle in tare condition (an empty freight vehicle) being lifted momentarily, and leaving the track. This effect was relatively common in the nineteenth century. On curved sections, the longitudinal (traction or braking) forces between vehicles have a component inward or outward respectively on the curve. In extreme situations these lateral forces may be enough to produce derailment. A special case of train handling problems

936-600: A Federalist Party leader whom Adams viewed as overly favorable to Britain. Unlike other New England Federalists, Adams supported the Jefferson administration's Louisiana Purchase and expansionist policies. Adams was the lone Federalist in Congress to vote for the Non-importation Act of 1806 that punished Britain for its attacks on American shipping during the ongoing Napoleonic Wars . Adams became increasingly frustrated with
1092-611: A book of constitutional law instead of on a Bible . In his inaugural address, he adopted a post-partisan tone, promising to avoid party-building and politically motivated appointments. He also proposed an elaborate program of "internal improvements": roads, ports, and canals. Though some were worried about the constitutionality of such federal projects, Adams argued that the General Welfare Clause provided for broad constitutional authority. He promised that he would ask Congress to authorize many such projects. Adams presided over
1248-438: A common axle: the wheels on both sides rotate in unison. Tramcars requiring low floor levels are the exception, but much benefit in vehicle guidance is lost by having unlinked wheels. The benefit of linked wheels derives from the conicity of the wheel treads —the wheel treads are not cylindrical , but conical . On idealised straight track, a wheelset would run centrally, midway between the rails. The example shown here uses
1404-410: A considerable force to make it happen, and the friction force resisting the sliding is designated "L", the lateral force. The wheelset applies a force L outwards to the rails, and the rails apply a force L inwards to the wheels. Note that this is quite independent of "centrifugal force". However at higher speeds the centrifugal force is added to the friction force to make L. The load (vertical force) on
1560-458: A designated distance apart (known as the track gauge ), and supported on transverse sleepers (ties). Some advanced track structures support the rails on a concrete or asphalt slab. The running surface of the rails is required to be practically continuous and of the proper geometrical layout. In the event of a broken or cracked rail , the rail running surface may be disrupted if a piece has fallen out, or become lodged in an incorrect location, or if
1716-453: A detailed political platform in the same way that Adams did, his coalition united in opposition to Adams's reliance on government planning. Adams, meanwhile, clung to the hope of a non-partisan nation, and he refused to make full use of the power of patronage to build up his own party structure. During the first half of his administration, Adams avoided taking a strong stand on tariffs, partly because he wanted to avoid alienating his allies in
SECTION 10
#17328581678261872-550: A harmonious and productive cabinet that he met with on a weekly basis. Like Monroe, Adams sought a geographically balanced cabinet that would represent the various party factions, and he asked the members of the Monroe cabinet to remain in place for his own administration. Samuel L. Southard of New Jersey stayed on as Secretary of the Navy , William Wirt kept his post of Attorney General , and John McLean of Ohio continued to serve as
2028-431: A large component is from the crabbing of a wheelset which has a non-zero angle of attack during running with flange contact. The L/V excess can result from wheel unloading, or from improper rail or wheel tread profiles. The physics of this is more fully described below, in the section wheel-rail interaction . Wheel unloading can be caused by twist in the track. This can arise if the cant (crosslevel, or superelevation) of
2184-527: A large gap between the remaining rail sections arises. 170 broken (not cracked) rails were reported on Network Rail in the UK in 2008, down from a peak of 988 in 1998/1999. Derailment may take place due to excessive gauge widening (sometimes known as road spread ), in which the sleepers or other fastenings fail to maintain the proper gauge. In lightly engineered track where rails are spiked (dogged) to timber sleepers, spike hold failure may result in rotation outwards of
2340-404: A less sharply curved path than the actual curve of the track. The angle between the natural path and the actual path is called the angle of attack (or the yaw angle). As the wheelset rolls forward, it is forced to slide across the railhead by the flange contact. The whole wheelset is forced to do this, so the wheel on the low rail is also forced to slide across its rail. This sliding requires
2496-510: A majority of the electoral votes for vice president. Adams nearly swept the electoral votes of New England and won a majority of the electoral votes in New York , but he won just six electoral votes from the slave states. Most of Jackson's support came from slave-holding states, but he also won New Jersey , Pennsylvania , and some electoral votes from the Northwest. As no candidate won a majority of
2652-586: A majority of the vote, the state legislature decided the election. Rather than seek election by the legislature, Adams withdrew his name from contention, and the legislature selected Davis. Adams was nearly elected to the Senate in 1835 by a coalition of Anti-Masons and National Republicans, but his support for Jackson in a minor foreign policy matter annoyed National Republican leaders enough that they dropped their support for his candidacy. After 1835, Adams never again sought higher office, focusing instead on his service in
2808-429: A more positive light during his post-presidency because of his vehement stance against slavery, as well as his fight for the rights of women and Native Americans. John Quincy Adams was born on July 11, 1767, to John and Abigail Adams (née Smith) in a part of Braintree , Massachusetts , that is now Quincy . He was named after his mother's maternal grandfather, Colonel John Quincy , after whom Quincy, Massachusetts,
2964-583: A national university, and engagement with the countries of Latin America, but Congress refused to pass many of his initiatives. During Adams's presidency , the Democratic-Republican Party split into two major camps: the National Republican Party , which supported Adams, and Andrew Jackson's Democratic Party . The Democrats proved to be more effective political organizers than Adams and his National Republican supporters, and Jackson soundly defeated Adams in
3120-554: A productive working relationship with Russian official Nikolay Rumyantsev and eventually befriended Tsar Alexander I of Russia . Adams continued to favor American neutrality between France and Britain during the Napoleonic War . Louisa was initially distraught at the prospect of living in Russia, but she became a popular figure at the Russian court. From his diplomatic post, Adams observed
3276-461: A professor of logic at Brown University and as the Boylston Professor of Rhetoric and Oratory at Harvard University . Adams's devotion to classical rhetoric shaped his response to public issues, and he would remain inspired by those rhetorical ideals long after the neo-classicalism and deferential politics of the founding generation were eclipsed by the commercial ethos and mass democracy of
SECTION 20
#17328581678263432-417: A prominent advocate of internal improvements and protective tariffs within the administration. Adams chose Henry Clay as Secretary of State , angering those who believed Clay had offered Adams his support in the 1824 election in exchange for the most prestigious position in the cabinet. Clay would later regret accepting the job since it reinforced the "Corrupt Bargain" accusation. However, Clay's strength in
3588-457: A rail, usually under the aggravating action of crabbing of bogies (trucks) on curves. The mechanism of gauge widening is usually gradual and relatively slow, but if it is undetected, the final failure often takes place under the effect of some additional factor, such as excess speed, poorly maintained running gear on a vehicle, misalignment of rails, and extreme traction effects (such as high propelling forces). The crabbing effect referred to above
3744-419: A republic that had been established through a slave revolt . Though the United States delegation finally won confirmation from the Senate, it never reached the Congress of Panama due to the Senate's delay. The Jacksonians formed an effective party apparatus that adopted many modern campaign techniques. Rather than focusing on issues, they emphasized Jackson's popularity and the supposed corruption of Adams and
3900-422: A right-curving section of track. The focus is on the left-side wheel, which is more involved with the forces critical to guiding the railcar through the curve. Diagram 1 below shows the wheel and rail with the wheelset running straight and central on the track. The wheelset is running away from the observer. (Note that the rail is shown inclined inwards; this is done on modern track to match the rail head profile to
4056-564: A series of pseudonymously published essays arguing that Britain provided a better governmental model than France. Two years later, he published another series of essays attacking Edmond-Charles Genêt , a French diplomat who sought to undermine President George Washington 's policy of neutrality in the French Revolutionary Wars . In 1794, Washington appointed Adams as the U.S. ambassador to the Netherlands . Adams considered declining
4212-571: A single vehicle may obstruct the clear line. If a train collides with a massive object, it is clear that derailment of the proper running of vehicle wheels on the track may take place. Although very large obstructions are imagined, it has been known for a cow straying on to the line to derail a passenger train at speed such as occurred in the Polmont rail accident . The most common obstructions encountered are road vehicles at level crossings (grade crossings); malicious persons sometimes place materials on
4368-399: A train are connected by couplings; in the early days of railways these were short lengths of chain ("loose couplings") that connected adjacent vehicles with considerable slack. Even with later improvements there may be a considerable slack between the traction situation (power unit pulling the couplings tight), and power unit braking (locomotive applying brakes and compressing buffers throughout
4524-422: A train can be caused by a collision with another object, an operational error (such as excessive speed through a curve), the mechanical failure of tracks (such as broken rails), or the mechanical failure of the wheels, among other causes. In emergency situations, deliberate derailment with derails or catch points is sometimes used to prevent a more serious accident. The first recorded train derailment in history
4680-424: Is overspeed on sharp curves . This generally arises when a driver fails to slow the train for a sharp curved section in a route that otherwise has higher speed conditions. In the extreme this results in the train entering a curve at a speed at which it cannot negotiate the curve, and gross derailment takes place. The specific mechanism of this may involve bodily tipping (rotation) but is likely to involve disruption of
4836-566: Is also named. Colonel Quincy died two days after his great-grandson's birth. Young Adams was educated by tutors – his cousin James Thaxter and his father's law clerk, Nathan Rice. He soon exhibited literary skills, and in 1779 he started a diary that he kept until just before he died in 1848. Until the age of ten, Adams grew up on the family farm in Braintree, largely in the care of his mother. Though frequently absent because of his participation in

The train was traveling between Hightstown and Spotswood, New Jersey, and derailed after an axle broke on one of the carriages as a result of a journal box catching fire. The derailment resulted in one casualty and twenty-three injuries, and it was recorded that both New York railroad magnate Cornelius Vanderbilt and former U.S president John Quincy Adams were on
5304-737: Is managed by stressing continuously welded rails (they are tensioned mechanically to be stress neutral at a moderate temperature) and by providing proper expansion gaps at joints and ensuring that fishplates are properly lubricated. In addition, lateral restraint is provided by an adequate ballast shoulder. If any of these measures are inadequate, the track may buckle; a large lateral distortion takes place, which trains are unable to negotiate. (In nine years 2000/1 to 2008/9 there were 429 track buckle incidents in Great Britain). Junctions and other changes of routing on railways are generally made by means of points (switches – movable sections capable of changing
5460-426: Is more marked in dry conditions, when the coefficient of friction at the wheel to rail interface is high. The running gear – wheelsets , bogies (trucks), and suspension—may fail. The most common historical failure mode is collapse of plain bearings due to deficient lubrication, and failure of leaf springs; wheel tyres are also prone to failure due to metallurgical crack propagation. Modern technologies have reduced
5616-455: Is quite steep, and flange climbing is unlikely. However, if the rail head is side-worn (side-cut) or the flange is worn, as shown in Diagram 6 the contact angle is much flatter and flange climbing is more likely. Once the wheel flange has completely climbed onto the rail head, there is no lateral restraint, and the wheelset is likely to follow the yaw angle, resulting in the wheel dropping outside
5772-532: Is undertaken, it is possible for poor workmanship to produce a ramp in the profile in the facing direction, that deflects an approaching wheel flange on to the rail head. In extreme situations, the infrastructure may be grossly distorted or even absent; this may arise from a variety of causes, including earthwork movement (embankment slips and washouts), earthquakes and other major terrestrial disruptions, or deficient protection during work processes, among others. Nearly all practical railway systems use wheels fixed to
5928-526: The 1824 presidential election . Because no candidate won a majority of electoral votes , the House of Representatives held a contingent election , which Adams won with the support of Speaker of the House Henry Clay, whom Adams would controversially appoint as his secretary of state. As president, Adams called for an ambitious agenda that included federally funded infrastructure projects , the establishment of
6084-443: The 1828 presidential election , making Adams the second president to fail to win re-election (his father being the first). Rather than retiring from public service, Adams won election to the House of Representatives, where he would serve from 1831 until his death in 1848. He remains the only former president to be elected to the chamber. After narrowly losing his bids for Governor of Massachusetts and Senate re-election, Adams joined
6240-772: The Adams–Onís Treaty , which provided for the American acquisition of Florida. He also helped formulate the Monroe Doctrine , which became a key tenet of U.S. foreign policy . In 1818, Adams was elected a member of the American Philosophical Society in Philadelphia. Adams, Andrew Jackson , William H. Crawford , and Henry Clay —all members of the Democratic-Republican Party—competed in

With his father's encouragement, Adams would also translate classical authors such as Virgil , Horace , Plutarch , and Aristotle . In 1778, Adams and his father departed for Europe, where John Adams would serve as part of American diplomatic missions in France and

6552-507: The American System , was designed to unite disparate regional interests in the promotion of a thriving national economy. Adams's programs faced opposition from various quarters. Many disagreed with his broad interpretation of the constitution and preferred that power be concentrated in state governments rather than the federal government. Others disliked interference from any level of government and were opposed to central planning. Some in
6708-743: The Anti-Masonic Party in the early 1830s before joining the Whig Party , which united those opposed to President Jackson. During his time in Congress, Adams became increasingly critical of slavery and of the Southern leaders whom he believed controlled the Democratic Party. He was particularly opposed to the annexation of Texas and the Mexican–American War , which he saw as a war to extend slavery and its political grip on Congress . He also led
6864-628: The Anti-Masonic Party , partly because the National Republican Party's leadership in Massachusetts included many of the former Federalists that Adams had clashed with earlier in his career. The Anti-Masonic Party originated as a movement against Freemasonry , but it developed into the country's first third party and embraced a general program of anti-elitism. Adams expected a light workload when he returned to Washington at 64 years old, but Speaker Andrew Stevenson selected Adams chair of
7020-775: The British West Indies , dealing a blow to Adams's prestige. The Adams administration negotiated extensively with the British to lift this ban, but the two sides could not reach an agreement. Despite the loss of trade with the British West Indies, the other commercial agreements secured by Adams helped expand the overall volume of United States exports. Aside from an unsuccessful attempt to purchase Texas from Mexico, President Adams did not seek to expand into Latin America or North America. Adams and Clay instead sought engagement with Latin America to prevent it from falling under
7176-632: The Committee on Commerce and Manufactures . Though he identified as a member of the Anti-Masonic Party, Congress was broadly polarized into allies of Jackson and opponents of Jackson, and Adams generally aligned with the latter camp. Stevenson, an ally of Jackson, expected that the committee chairmanship would keep Adams busy defending the tariff even while the Jacksonian majority on the committee would prevent Adams from accruing any real power. As chair of
7332-674: The Jacksonian Era . Many of Adams's idiosyncratic positions were rooted in his abiding devotion to the Ciceronian ideal of the citizen-orator "speaking well" to promote the welfare of the polis. He was also influenced by the classical republican ideal of civic eloquence espoused by British philosopher David Hume . Adams adapted these classical republican ideals of public oratory to the American debate, viewing its multilevel political structure as ripe for "the renaissance of Demosthenic eloquence". His Lectures on Rhetoric and Oratory (1810) looks at

In 1781, Adams traveled to Saint Petersburg , Russia, where he served as the secretary to the American diplomat, Francis Dana . He returned to the Netherlands in 1783 and accompanied his father to Great Britain in 1784. Though Adams enjoyed Europe, he and his family decided he needed to return to
7644-635: The Peninsular War . In addition to his foreign policy role, Adams held several domestic duties, including overseeing the 1820 United States census and writing an extensive report on weights and measures . The weights and measures report, a particular passion of Adams', provided an extensive historical perspective on the topic and advocated for adoption of the metric system . Monroe and Adams agreed on most major foreign policy issues: both favored neutrality in Latin American independence wars , peace with
7800-710: The Postmaster General , an important position that was not part of the cabinet at that time. Adams's first choices for Secretary of War and Secretary of the Treasury were Andrew Jackson and William Crawford, but each declined to serve in the administration. Adams instead selected James Barbour of Virginia , a prominent supporter of Crawford, to lead the War Department . Leadership of the Treasury Department went to Richard Rush of Pennsylvania , who would become
7956-555: The Tariff of 1828 , which became known as the "Tariff of Abominations" by opponents. Adams was denounced in the South, and he received little credit for the tariff in the North. Adams sought the gradual assimilation of Native Americans via consensual agreements, a priority shared by few whites in the 1820s. Yet Adams was also deeply committed to the westward expansion of the United States. Settlers on

The crisis ended when Clay and Calhoun agreed to another tariff bill, the Tariff of 1833 , that furthered lower tariff rates. Adams was appalled by the Nullification Crisis's outcome, as he felt that the Southern states had unfairly benefited from challenging federal law. After the crisis, Adams was convinced that Southerners exercised undue influence over
8268-797: The U.S. ambassador to Portugal . Later that year, John Adams defeated Jefferson in the 1796 presidential election . When the elder Adams became president, he appointed his son as the U.S. ambassador to Prussia . Though concerned that his appointment would be criticized as nepotistic , Adams accepted the position and traveled to the Prussian capital of Berlin with his wife and his younger brother, Thomas Boylston Adams . The State Department tasked Adams with developing commercial relations with Prussia and Sweden, but President Adams also asked his son to write to him frequently about affairs in Europe. His advice that he regularly gave to his father based on his experiences on

Adams presided over major repairs and further construction on the National Road, and shortly after he left office the National Road extended from Cumberland, Maryland , to Zanesville, Ohio . The Adams administration also saw the beginning of the Chesapeake and Ohio Canal ;

By the end of the first session of the 19th United States Congress , an anti-Adams congressional coalition consisting of Jacksonians (led by Benton and Hugh Lawson White ), Crawfordites (led by Martin Van Buren and Nathaniel Macon ), and Calhounites (led by Robert Y. Hayne and George McDuffie ) had emerged. Aside from Clay, Adams lacked strong supporters outside of

As part of this goal, the administration favored sending a United States delegation to the Congress of Panama , an 1826 conference of New World republics organized by Simón Bolívar . Clay and Adams hoped that the conference would inaugurate a " Good Neighborhood Policy " among the independent states of the Americas. However, the funding for a delegation and

In 1809, President James Madison , a member of the Democratic-Republican Party, appointed Adams as the U.S. ambassador to Russia . Multilingual , Adams held diplomatic posts for the duration of Madison's presidency, and he served as part of the American delegation that negotiated an end to the War of 1812 . In 1817, President James Monroe selected Adams as his secretary of state. In that role, Adams negotiated
9048-512: The Federalist minority in Congress. Like his Federalist colleagues, he opposed the impeachment of Associate Justice Samuel Chase , an outspoken supporter of the Federalist Party. Adams had strongly opposed Jefferson's 1800 presidential candidacy, but he gradually became alienated from the Federalist Party. His disaffection was driven by the party's declining popularity, disagreements over foreign policy, and Adams's hostility to Timothy Pickering ,

In February 1811, President Madison nominated Adams as an Associate Justice of the United States Supreme Court . The nomination was unanimously confirmed by the Senate, but Adams declined the seat, preferring a career in politics and diplomacy, so Joseph Story took the seat instead. Adams had long feared that

In the 1836 presidential election Democrats put forward Martin Van Buren , while the Whigs fielded multiple presidential candidates. Because he disdained all the major party contenders for president, Adams did not take part in

#17328581678269672-576: The House of Representatives. Though they were quite different in temperament and had clashed in the past, Adams and Clay shared similar views on national issues. By contrast, Clay viewed Jackson as a dangerous demagogue , and he was unwilling to support Crawford due to the latter's health issues. Adams and Clay met before the contingent election, and Clay agreed to support Adams in the election. Adams also met with Federalists such as Daniel Webster , promising that he would not deny governmental positions to members of their party. On February 9, 1825, Adams won
9828-622: The Monroe Doctrine, which was largely built upon Adams's ideas. In issuing the Monroe Doctrine, the United States displayed a new level of assertiveness in international relations, as the doctrine represented the country's first claim to a sphere of influence . It also marked the country's shift in psychological orientation away from Europe and towards the Americas. Debates over foreign policy would no longer center on relations with Britain and France, but instead focus on western expansion and relations with Native Americans. The doctrine became one of

After extended negotiations, Spain and the United States agreed to the Adams–Onís Treaty , which was ratified in February 1821. Adams was deeply proud of the treaty, though he privately was concerned by the potential expansion of slavery into
10140-617: The Muscogee. A showdown between Georgia and the federal government was only averted after the Muscogee agreed to a third treaty. Though many saw Troup as unreasonable in his dealings with the federal government and the Native Americans, the administration's handling of the incident alienated those in the Deep South who favored immediate Indian removal . Adams famously said "America goes not abroad, in search of monsters to destroy". One of

Supporters of Adams began calling themselves National Republicans , while supporters of Jackson began calling themselves Democrats . In the press, they were often described as "Adams Men" and "Jackson Men". In the 1826 elections , Adams's opponents picked up seats throughout
10452-779: The Prussian region of Silesia were published in a book titled Letters on Silesia . During his time in Prussia, Adams befriended the German diplomat and writer Friedrich von Gentz , whose work, The Origins and Principles of the American Revolution, Compared with the Origins and Principles of the French Revolution, Adams would translate into English in 1800. In the 1800 presidential election , Jefferson defeated John Adams, and both Adams and his son left office in early 1801. On his return to

Later that year, President James Madison appointed Adams as
10764-432: The South and New England. After Jacksonians took power in 1827, they devised a tariff bill designed to appeal to Western states while instituting high rates on imported materials important to the economy of New England. It is unclear whether Van Buren, who shepherded the bill through Congress, meant for the bill to pass, or if he had deliberately designed it to force Adams and his allies to oppose it. Regardless, Adams signed
10920-413: The South feared that Adams was secretly an abolitionist and that he sought to subordinate the states to the federal government. Most of the president's proposals were defeated in Congress. Adams's ideas for a national university, a national observatory, and the establishment of a uniform system of weights and measures never received congressional votes. His proposal for the creation of a naval academy won
11076-406: The Southern United States, and many of those settlers owned slaves despite an 1829 Mexican law that abolished slavery. Many in the United States and Texas thus favored the admission of Texas into the union as a slave state . Adams considered the issue of Texas to be "a question of far deeper root and more overshadowing branches than any or all others that agitate the country", and he emerged as one of

Apart from the Monroe doctrine, his last four years as Secretary of State were less successful because he was preoccupied with his presidential campaign and refused to make compromises with other countries that might have weakened his candidacy; the result was a small-scale trade war but a successful election to the White House. Taking office in

The negotiations were interrupted by an escalation of the Seminole War , and in December 1818, Monroe ordered General Andrew Jackson to enter Florida and retaliate against Seminoles that had raided Georgia. Exceeding his orders, Jackson captured the Spanish outposts of St. Marks and Pensacola and executed two Englishmen. While Jackson's actions outraged
11544-766: The Treasury Albert Gallatin , and Federalist Senator James A. Bayard to a delegation charged with negotiating an end to the war. Gallatin and Bayard arrived in St. Petersburg in July 1813, but the British declined Tsar Alexander's offer of mediation. Hoping to start negotiations at another venue, Adams left Russia in April 1814. Negotiations finally began in mid-1814 in Ghent , where Adams, Gallatin, and Bayard were joined by two additional American delegates, Jonathan Russell and former Speaker of
11700-541: The Treasury William H. Crawford , Secretary of War John C. Calhoun , Secretary of the Navy Benjamin Crowninshield , and Attorney General William Wirt . Adams developed a strong respect for Calhoun but believed that Crawford was unduly focused on succeeding Monroe in 1824. During his time as ambassador to Britain, Adams had begun negotiations over several contentious issues that had not been solved by
11856-478: The Treasury Richard Rush as his running mate. The 1828 election thus marked the first time in United States history that a presidential ticket composed of two Northerners faced off against a presidential ticket composed of two Southerners. In the election, Jackson won 178 of the 261 electoral votes and just under 56% of the popular vote. Jackson won 50.3% of the popular vote in the free states, but 72.6% of
12012-579: The U.S. had long sought to purchase. Spain struggled to control the Indian tribes active in Florida, and some of those tribes raided United States territory. To the west, New Spain bordered the territory acquired by the United States in the Louisiana Purchase, but no clear boundary had been established between United States and Spanish territory. After taking office, Adams began negotiations with Luis de Onís ,
12168-564: The United Kingdom, rejection of a trade agreement with the French, and peaceful expansion into the Spanish Empire 's North American territories. The president and his secretary of state developed a strong working relationship, and while Adams often influenced Monroe's policies, he respected that Monroe made the final decisions on major issues. Monroe met regularly with his five-person cabinet , which initially consisted of Adams, Secretary of
12324-563: The United States Derailments result from one or more of a number of distinct causes; these may be classified as: Broken rails are a leading cause of derailments. According to data from the Federal Railroad Administration, broken rails and welds are the most common reason for train derailments, making up more than 15 percent of derailment cases. A traditional track structure consists of two rails, fixed at
12480-536: The United States and Britain should work together to preserve the independence of these fledgling republics. The cabinet debated whether to accept the offer, but Adams opposed it. Instead, Adams urged Monroe to publicly declare the United States' opposition to any European attempt to colonize or re-take control of territory in the Americas, while also committing the United States to neutrality in European affairs. In his December 1823 annual message to Congress , Monroe laid out
12636-523: The United States from 1797 to 1801, and First Lady Abigail Adams . Initially a Federalist like his father, he won election to the presidency as a member of the Democratic-Republican Party , and later, in the mid-1830s, became affiliated with the Whig Party . Born in Braintree, Massachusetts , Adams spent much of his youth in Europe, where his father served as a diplomat. After returning to
12792-527: The United States to complete his education and eventually launch a political career. Adams returned to the United States in 1785 and earned admission as a member of the junior class of Harvard College the following year. He joined Phi Beta Kappa and excelled academically, graduating second in his class in 1787. After graduating from Harvard, he studied law with Theophilus Parsons in Newburyport, Massachusetts , from 1787 to 1789. Adams initially opposed
12948-450: The United States would enter a war it could not win against Britain, and by early 1812, he saw such a war as inevitable due to the constant British attacks on American shipping and the British practice of impressment . In mid-1812, the United States declared war against Britain, beginning the War of 1812 . Tsar Alexander attempted to mediate the conflict between Britain and the United States, and President Madison appointed Adams, Secretary of
13104-529: The United States, Adams established a successful legal practice in Boston . In 1794, President George Washington appointed Adams as the U.S. ambassador to the Netherlands , and Adams would serve in high-ranking diplomatic posts until 1801, when Thomas Jefferson took office as president. Federalist leaders in Massachusetts arranged for Adams's election to the United States Senate in 1802, but Adams broke with
13260-589: The United States, Adams re-established a legal practice in Boston , and in April 1802 he was elected to the Massachusetts Senate . In November of that year, he ran unsuccessfully for the United States House of Representatives . In February 1803, the Massachusetts legislature elected Adams to the United States Senate . Though somewhat reluctant to affiliate with any political party, Adams joined
13416-522: The United States, and did not make a major diplomatic issue out of Jackson's execution of two British nationals. Negotiations between Spain and the United States continued, and Spain agreed to cede Florida. The determination of the western boundary of the United States proved more difficult. American expansionists favored setting the border at the Rio Grande , but Spain, intent on protecting its colony of Mexico from American encroachment, insisted on setting
13572-465: The United States, but they married in All Hallows-by-the-Tower on July 26, 1797. Shortly after the wedding, Joshua Johnson fled England to escape his creditors, and Adams did not receive the dowry that Johnson had promised him, much to the embarrassment of Louisa. Adams noted in his own diary that he had no regrets about his decision to marry Louisa. In 1796, Washington appointed Adams as
13728-730: The War of 1812 or the Treaty of Ghent. In 1817, the two countries agreed to the Rush–Bagot Treaty , which limited naval armaments on the Great Lakes . Negotiations between the two powers continued, resulting in the Treaty of 1818 , which defined the Canada–United States border west of the Great Lakes. The boundary was set at the 49th parallel to the Rocky Mountains , while the territory to
13884-505: The West and interest in foreign policy made him a natural choice for the position. In his 1825 annual message to Congress, Adams presented a comprehensive and ambitious agenda. He called for major investments in internal improvements as well as the creation of a national university, a naval academy, and a national astronomical observatory. Noting the healthy status of the treasury and the possibility for more revenue via land sales, Adams argued for
14040-530: The aftermath of the War of 1812, Adams thought that the country had been fortunate in avoiding territorial losses, and he prioritized avoiding another war with a European power, particularly Britain. He also sought to avoid exacerbating sectional tensions, which had been a major issue for the country during the War of 1812. One of the major challenges confronting Adams was how to respond to the power vacuum in Latin America that arose from Spain's weakness following
14196-399: The aid of Clay and Gallatin, Adams negotiated a limited trade agreement with Britain. Following the conclusion of the trade agreement, much of Adams's time as ambassador was spent helping stranded American sailors and prisoners of war. In pursuit of national unity, newly elected president James Monroe decided a Northerner would be optimal for the position of Secretary of State , and he chose
14352-458: The approval of the Senate but was defeated in the House; opponents objected to the naval academy's cost and worried that the establishment of such an institution would "produce degeneracy and corruption of the public morality". Adams's proposal to establish a national bankruptcy law was also defeated. Unlike other aspects of his domestic agenda, Adams won congressional approval for several ambitious infrastructure projects. Between 1824 and 1828,
14508-578: The boundary at the Sabine River . At Monroe's direction, Adams agreed to the Sabine River boundary, but he insisted that Spain cede its claims on Oregon Country. Adams was deeply interested in establishing American control over the Oregon Country, partly because he believed that control of that region would spur trade with Asia. The acquisition of Spanish claims to the Pacific Northwest also allowed
14664-564: The campaign turned increasingly nasty. The Jacksonian press portrayed Adams as an out-of-touch elitist, while pro-Adams newspapers attacked Jackson's past involvement in various duels and scuffles, portraying him as too emotional and impetuous for the presidency. Though Adams and Clay had hoped that the campaign would focus on the American System, it was instead dominated by the personalities of Jackson and Adams. Vice President Calhoun joined Jackson's ticket, while Adams turned to Secretary of
14820-516: The campaign; Van Buren won the election. Nonetheless, Adams became aligned with the Whig Party in Congress. Adams generally opposed the initiatives of President Van Buren, long a political adversary, though they maintained a cordial public relationship. The Republic of Texas won its independence from Mexico in the Texas Revolution of 1835–1836. Texas had largely been settled by Americans from
14976-478: The charisma of his competitors, Adams was widely respected and benefited from the lack of other prominent Northern political leaders. Adams's top choice for the role of vice president was General Andrew Jackson; Adams noted that "the Vice-Presidency was a station in which [Jackson] could hang no one, and in which he would need to quarrel with no one". However, as the 1824 election approached, Jackson jumped into
15132-406: The committee charged with writing tariff laws, Adams became an important player in the nullification crisis , which stemmed largely from Southern objections to the high rates imposed by the Tariff of 1828 . South Carolina leaders argued that states could nullify federal laws , and they announced that they would bar the federal government from enforcing the tariff in their state. Adams helped pass
15288-546: The completion of several projects that were in various stages of construction or planning, including a road from Washington, D.C. to New Orleans . He also proposed the establishment of a Department of the Interior as a new cabinet-level department that would preside over these internal improvements. Adams hoped to fund these measures primarily through Western land sales, rather than increased taxes or public debt. The domestic agenda of Adams and Clay, which would come to be known as
15444-486: The confirmation of delegation nominees became entangled in a political battle over Adams's domestic policies, with opponents such as Van Buren impeding the confirmation of a delegation. While Van Buren saw the Panama Congress as an unwelcome deviation from the more isolationist foreign policy established by President Washington, many Southerners opposed involvement with any conference attended by delegates from Haiti ,
15600-813: The construction of the Chesapeake & Delaware Canal and the Louisville and Portland Canal around the Falls of the Ohio ; the connection of the Great Lakes to the Ohio River system in Ohio and Indiana ; and the enlargement and rebuilding of the Dismal Swamp Canal in North Carolina . Additionally, the first passenger railroad in the United States, the Baltimore and Ohio Railroad ,
15756-445: The contingent election on the first ballot, taking 13 of the 24 state delegations. Adams won the House delegations of all the states in which he or Clay had won a majority of the electoral votes, as well as the delegations of Illinois , Louisiana , and Maryland . Adams's victory made him the first child of a president to serve as president himself. After the election, many of Jackson's supporters claimed that Adams and Clay had reached
15912-517: The country, as allies of Adams failed to coordinate among themselves. Andrew Stevenson , a Jackson supporter, replaced John Taylor, an Adams supporter, as Speaker of the House. As Adams himself noted, the United States had never seen a Congress that was firmly under the control of political opponents of the president. After the elections, Van Buren and Calhoun agreed to throw their support behind Jackson in 1828, with Van Buren bringing along many of Crawford's supporters. Though Jackson did not articulate
16068-500: The electoral votes, the House was required to hold a contingent election under the terms of the Twelfth Amendment . The House would decide among the top three electoral vote winners, with each state's delegation having one vote; thus, unlike his three rivals, Clay was not eligible to be elected by the House. Adams knew that his own victory in the contingent election would require the support of Clay, who wielded immense influence in
16224-631: The endorsement of the New England legislatures. The regional strength of each candidate played an important role in the election; Adams was popular in New England , Clay and Jackson were strong in the West, and Jackson and Crawford competed for the South. In the 1824 presidential election, Jackson won a plurality in the Electoral College , taking 99 of the 261 electoral votes, while Adams won 84, Crawford won 41, and Clay took 37. Calhoun, meanwhile, won
16380-461: The exit from the sidings. In some cases these are provided at the convergence of running lines. It occasionally happens that a driver incorrectly believes they have authority to proceed over the trap points, or that the signaller improperly gives such permission; this results in derailment. The resulting derailment does not always fully protect the other line: a trap point derailment at speed may well result in considerable damage and obstruction, and even
16536-464: The fate of ancient oratory, the necessity of liberty for it to flourish, and its importance as a unifying element for a new nation of diverse cultures and beliefs. Just as civic eloquence failed to gain popularity in Britain, in the United States interest faded in the second decade of the 19th century, as the "public spheres of heated oratory" disappeared in favor of the private sphere. After resigning from
16692-619: The federal government through their control of Jackson's Democratic Party. In the 1833 Massachusetts gubernatorial election , the Anti-Masonic Party nominated Adams in a four-way race between Adams, the National Republican candidate, the Democratic candidate, and a candidate of the Working Men's Party. The National Republican candidate, John Davis , won 40% of the vote, while Adams finished in second place with 29%. Because no candidate won
16848-503: The federal government. Jackson himself described the campaign as a "struggle between the virtue of the people and executive patronage". Adams, meanwhile, refused to adapt to the new reality of political campaigns, and he avoided public functions and refused to invest in pro-administration tools such as newspapers. In early 1827, Jackson was publicly accused of having encouraged his wife, Rachel , to desert her first husband. In response, followers of Jackson attacked Adams's personal life, and
17004-640: The first United States Minister to Russia in 1809. Though Adams had only recently broken with the Federalist Party, his support of Jefferson's foreign policy had earned him goodwill with the Madison Administration. Adams was well-qualified for the role after his experiences in Europe generally and Russia specifically. After a difficult passage through the Baltic Sea , Adams arrived in the Russian capital of St. Petersburg in October 1809. He quickly established
17160-402: The flange tends to climb up the flange angle. It is held down by the vertical load on the wheel V, so that if L/V exceeds the trigonometrical tangent of the flange contact angle, climbing will take place. The wheel flange will climb to the rail head where there is no lateral resistance in rolling movement, and a flange climbing derailment usually takes place. In Diagram 5 the flange contact angle
17316-463: The foundational principles of U.S. foreign policy . Immediately upon becoming Secretary of State, Adams emerged as one of Monroe's most likely successors, as the last three presidents had all served in the role before taking office. As the 1824 election approached, Henry Clay, John C. Calhoun (who later dropped out of the race), and William H. Crawford appeared to be Adams's primary competition to succeed Monroe. Crawford favored state sovereignty and
17472-673: The frontier, constantly seeking to move westward, cried for a more expansionist policy that disregarded the concerns of Native Americans. Early in his term, Adams suspended the Treaty of Indian Springs after learning that the Governor of Georgia, George Troup , had forced the treaty on the Muscogee . Adams signed a new treaty with the Muscogee in January 1826 that allowed the Muscogee to stay but ceded most of their land to Georgia. Troup refused to accept its terms and authorized all Georgian citizens to evict
17628-487: The ground in Europe proved particularly valuable during the Quasi-War with France, although President Adams also relied heavily on his official staff for such advice and not primarily on his son. In 1799, Adams negotiated a new trade agreement between the United States and Prussia , though he could never complete an agreement with Sweden. He frequently wrote to family members in the United States, and in 1801 his letters about
17784-401: The incidence of these failures considerably, both by design (specially the elimination of plain bearings) and intervention (non-destructive testing in service). If a vertical, lateral, or crosslevel irregularity is cyclic and takes place at a wavelength corresponding to the natural frequency of certain vehicles traversing the route section, there is a risk of resonant harmonic oscillation in
17940-453: The leading congressional opponents of annexation. When he served as secretary of state, Adams had sought to acquire Texas, but he argued that, because Mexico had abolished slavery, the acquisition of Texas would transform the region from a free territory into a slave state. He also feared that the annexation of Texas would encourage Southern expansionists to pursue other potential slave states, including Cuba . Adams's firm stance may have played
18096-455: The left wheel is a little faster than the forward speed of the right wheel. This causes the wheelset to curve to the right, correcting the displacement. This takes place without flange contact; the wheelsets steer themselves on moderate curves without any flange contact. The sharper the curve, the greater the lateral displacement necessary to achieve the curving. On a very sharp curve (typically less than about 500 m or 1,500 feet radius)
18252-555: The major foreign policy goals of the Adams administration was the expansion of American trade. His administration reached reciprocity treaties with a number of nations, including Denmark, Prussia , and the Federal Republic of Central America . The administration also reached commercial agreements with the Kingdom of Hawaii and the Kingdom of Tahiti . Agreements with Denmark and Sweden opened their colonies to American trade, but Adams
18408-605: The newly acquired territories. In 1824, the Monroe administration would strengthen US claims to Oregon by ratifying the Russo-American Treaty of 1824 , which established Russian Alaska 's southern border at 54°40′ north. As the Spanish Empire continued to fracture during Monroe's second term, Adams, Monroe and Clay became increasingly concerned that the " Holy Alliance " of Prussia , Austria, and Russia would seek to bring Spain's erstwhile colonies under their control, to
18564-414: The newly independent republics of Latin America to avoid the risk of war with Spain and its European allies. However, Andrew Jackson's military campaign in Florida and Henry Clay's threats in Congress forced Spain to cut a deal, which Adams negotiated successfully. Biographer James Lewis says, "He managed to play the cards that he had been dealt – cards that he very clearly had not wanted – in ways that forced
18720-480: The onward route of vehicles). In the early days of railways these were moved independently by local staff. Accidents – usually collisions – took place when staff forgot which route the points were set for, or overlooked the approach of a train on a conflicting route. If the points were not correctly set for either route – set in mid-stroke – it is possible for a train passing to derail. The first concentration of levers for signals and points brought together for operation
18876-416: The outer wheel is designated V, so that in Diagram 4 the two forces L and V are shown. The steel-to-steel contact has a coefficient of friction that may be as high as 0.5 in dry conditions, so that the lateral force may be up to 0.5 of the vertical wheel load. During this flange contact, the wheel on the high rail is experiencing the lateral force L, towards the outside of the curve. As the wheel rotates,
19032-586: The point of even contemplating a Holy Alliance of their own to defend democracy. In his 1821 Fourth of July address, Adams addressed this issue, noting a shared "chain of sympathy" between the U.S. and Latin America, but arguing for neutrality rather than a Holy Alliance. In 1822, following the conclusion of the Adams–Onís Treaty, the Monroe administration recognized the independence of several Latin American countries, including Argentina and Mexico. In 1823, British Foreign Secretary George Canning suggested that
19188-583: The presidential nomination of the Tennessee legislature for the 1828 election. Though he had been close to Adams during Monroe's presidency, Vice President Calhoun was also politically alienated from the president by the appointment of Clay, since that appointment established Clay as the natural heir to Adams. Adams's ambitious December 1825 annual message to Congress further galvanized the opposition, with important figures such as Francis Preston Blair of Kentucky and Thomas Hart Benton of Missouri breaking with
19344-693: The race for president, and Calhoun ended up receiving the Vice-presidential support of Adams supporters. While the other candidates based their candidacies on their long tenure as congressmen, ambassadors, or members of the cabinet, Jackson's appeal rested on his military service, especially in the Battle of New Orleans . The congressional nominating caucus had decided upon previous Democratic-Republican presidential nominees, but it had become largely discredited by 1824. Candidates were instead nominated by state legislatures or nominating conventions, and Adams received
19500-503: The rail. An L/V ratio greater than 0.6 is considered to be hazardous. It is emphasised that this is a much simplified description of the physics; complicating factors are creep, actual wheel and rail profiles, dynamic effects, stiffness of longitudinal restraint at axleboxes, and the lateral component of longitudinal (traction and braking) forces. John Quincy Adams [REDACTED] John Quincy Adams ( / ˈ k w ɪ n z i / ; July 11, 1767 – February 23, 1848)
19656-438: The rails, and in some cases relatively small objects cause a derailment by guiding one wheel over the rail (rather than by gross collision). Derailment has also been brought about in situations of war or other conflict, such as during hostility by Native Americans, and more especially during periods when military personnel and materiel was being moved by rail. The handling of a train can also cause derailments. The vehicles of
19812-559: The ratification of the United States Constitution , but he ultimately came to accept the document, and in 1789 his father was elected as the first vice president of the United States . In 1790, Adams opened his own legal practice in Boston . Despite some early struggles, he was successful as an attorney and established financial independence from his parents. Adams initially avoided becoming involved in politics, instead focusing on building his legal career. In 1791, he wrote
19968-400: The repeal of the " gag rule ", which had prevented the House of Representatives from debating petitions to abolish slavery . Historians concur that Adams was one of the greatest diplomats and secretaries of state in American history; they typically rank him as an average president, as he had an ambitious agenda but could not get it passed by Congress. By contrast, historians also view Adams in
20124-621: The respected and experienced Adams for the role. Having spent several years in Europe, Adams returned to the United States in August 1817. Adams served as Secretary of State during Monroe's eight-year presidency, from 1817 to 1825. Many of his successes as secretary, such as the convention of 1818 with the United Kingdom, the Transcontinental Treaty with Spain, and the Monroe Doctrine, were not preplanned strategies but responses to unexpected events. Adams wanted to delay American recognition of
20280-420: The rest of the cabinet, Adams defended them as necessary to the country's self-defense, and he eventually convinced Monroe and most of the cabinet to support Jackson. Adams informed Spain that its failure to police its own territory had compelled Jackson to act, and he advised Spain to either secure the region or sell it to the United States. The British, meanwhile, declined to risk their recent rapprochement with
20436-410: The role, but ultimately took the position on the advice of his father. While abroad, Adams continued to urge neutrality, arguing that the United States would benefit economically by staying out of the ongoing French Revolutionary Wars. His chief duty as the ambassador to the Netherlands was to secure and maintain loans essential to U.S. finances. On his way to the Netherlands, he met with John Jay , who

20748-444: The signal (to apply or release brakes) propagates along the train. If a train driver applies the train brakes suddenly and severely, the front part of the train is subject to braking forces first. (Where only the locomotive has braking, this effect is obviously more extreme). The rear part of the train may overrun the front part, and in cases where coupling condition is imperfect, the resultant sudden closing up (an effect referred to as
20904-444: The steering effect of the conicity of the wheel treads on moderate curves (down to a radius of about 500 m, or about 1,500 feet). On sharper curves flange contact takes place, and the guiding effect of the flange relies on a vertical force (the vehicle weight). A flange climbing derailment can result if the relationship between these forces, L/V, is excessive. The lateral force L results not only from centrifugal effects, but
21060-529: The suicide of his son, George Washington Adams , in 1829. He was appalled by many of the Jackson administration's actions, including its embrace of the spoils system and the prosecution of his close friend, Treasury Auditor Tobias Watkins , for embezzlement. Though they had once maintained a cordial relationship, Adams and Jackson each came to loathe the other in the decades after the 1828 election. Adams grew bored with his retirement and still felt that his career
21216-399: The suspension springing has a stiffness optimised for the loaded condition, or for a compromise loading condition, so that it is too stiff in the tare situation. The vehicle wheelsets become momentarily unloaded vertically so that the guidance required from the flanges or wheel tread contact is inadequate. A special case is heat related buckling : in hot weather the rail steel expands. This
21372-533: The track structure and derailment as the primary failure event, followed by overturning. Fatal instances include the Santiago de Compostela derailment in 2013 and the Philadelphia train derailment two years later of trains traveling about 100 miles per hour (160 km/h). Both went at about twice the maximum allowable speed for the curved section of track. The guidance system of practical railway vehicles relies on
21528-511: The track varies considerably over the wheelbase of a vehicle, and the vehicle suspension is very stiff in torsion. In the quasi-static situation it may arise in extreme cases of poor load distribution, or on extreme cant at low speed. If a rail has been subject to extreme sidewear, or a wheel flange has been worn to an improper angle, it is possible for the L/V ratio to exceed the value that the flange angle can resist. If weld repair of side-worn switches
21684-402: The train as it took place, in which Adams wrote about the event in his journal. During the 19th century derailments were commonplace, but progressively improved safety measures have resulted in a stable lower level of such incidents. A sampling of annual approximate numbers of derailments in the United States includes 3000 in 1980, 1000 in 1986, 500 in 2010, and 1000 in 2022. Derailments in
21840-399: The train). This results in coupling surge . More sophisticated technologies in use nowadays generally employ couplings that have no loose slack, although there is elastic movement at the couplings; continuous braking is provided, so that every vehicle on the train has brakes controlled by the driver. Generally this uses compressed air as a control medium, and there is a measurable time lag as
21996-549: The unwillingness of other Federalists to condemn British actions, including impressment , and he moved closer to the Jefferson administration. After Adams supported the Embargo Act of 1807 , the Federalist-controlled Massachusetts legislature elected Adams's successor several months before the end of his term, and Adams resigned from the Senate shortly thereafter. While a member of the Senate, Adams served as
22152-419: The vehicles, leading to extreme improper movement and possibly derailment. This is most hazardous when a cyclic roll is set up by crosslevel variations, but vertical cyclical errors also can result in vehicles lifting off the track; this is especially the case when the vehicles are in the tare (empty) condition, and if the suspension is not designed to have appropriate characteristics. The last condition applies if
22308-416: The vote in the slave states. No future presidential candidate would match Jackson's proportion of the popular vote until Theodore Roosevelt 's 1904 campaign, while Adams's loss made him the second one-term president, after his own father. By 1828, only two states did not hold a popular vote for president, and the number of votes in the 1828 election was triple that in the 1824 election. This increase in votes
22464-513: The west of the mountains, known as Oregon Country , would be jointly occupied. The agreement marked a watershed moment in United Kingdom–United States relations, as the United States focused on its southern and western borders and British concerns about American expansionism subsided. When Adams took office, Spanish possessions bordered the United States to the south and west. To the south, Spain retained control of Florida , which
22620-414: The wheel tread profile.) Diagram 2 shows the wheelset displaced to the left, due to curvature of the track or a geometrical irregularity. The left wheel (shown here) is now running on a slightly larger diameter; the right wheel opposite has moved to the left as well, towards the centre of the track, and is running on a slightly smaller diameter. As the two wheels rotate at the same rate, the forward speed of
22776-429: The width of the wheel tread is not enough to achieve the necessary steering effect, and the wheel flange contacts the face of the high rail. Diagram 3 shows the running of wheelsets in a bogie or a four-wheeled vehicle. The wheelset is not running parallel to the track: it is constrained by the bogie frame and suspension, and it is yawing to the outside of the curve; that is, its natural rolling direction would lead along
22932-530: The winter of 1795–1796 in London , where he met Louisa Catherine Johnson , the second daughter of American merchant Joshua Johnson. In April 1796, Louisa accepted Adams's proposal of marriage. Adams's parents disapproved of his decision to marry a woman who had grown up in England, but he informed his parents that he would not reconsider his decision. Adams initially wanted to delay his wedding to Louisa until he returned to
23088-434: Was at Bricklayer's Arms Junction in south-east London in the period 1843–1844. The signal control location (forerunner of the signalbox) was enhanced by the provision of interlocking (preventing a clear signal being set for a route that was not available) in 1856. To prevent the unintended movement of freight vehicles from sidings to running lines, and other analogous improper movements, trap points and derails are provided at
23244-399: Was bolstered by the American victory in the Battle of Plattsburgh . By November 1814, the government of Lord Liverpool decided to seek an end to hostilities with the U.S. on the basis of status quo ante bellum . Even though a return to the status quo would mean the continuation of the British practice of impressment, Adams and his fellow commissioners had hoped for similar terms. The treaty
23400-427: Was constructed during Adams's presidency. Though many of these projects were undertaken by private actors, the government often provided money or land to aid the completion of such projects. In the immediate aftermath of the 1825 contingent election, Jackson was gracious to Adams. Nevertheless, Adams's appointment of Clay rankled Jackson, who received a flood of letters encouraging him to run. In 1825, Jackson accepted
23556-406: Was due not only to the recent wave of democratization, but also because of increased interest in elections and the growing ability of the parties to mobilize voters. Adams did not attend Jackson's inauguration, making him one of only four presidents who finished their terms but skipped the event. Adams considered permanently retiring from public life after his 1828 defeat, and he was deeply hurt by
23712-626: Was especially focused on opening trade with the British West Indies . The United States had reached a commercial agreement with Britain in 1815, but that agreement excluded British possessions in the Western Hemisphere. In response to United States pressure, the British had begun to allow a limited amount of American imports to the West Indies in 1823, but United States leaders continued to seek an end to Britain's protective Imperial Preference system.
