125-721: The Phoenix Foundry was a company that built steam locomotives and other industrial machinery in the city of Ballarat , Victoria , Australia . Over 30 years they built 352 locomotives for the Victorian Railways , of 38 different designs. The Phoenix Foundry was established in 1854 to build mining machinery and was incorporated as the Phoenix Foundry Co. Ltd. in 1870. The company was established by iron-founder William Shaw , moulder Robert Holden , and engine-smiths Richard Carter and George Threlfall . The business prospered, and by November 1861 it employed 96 men, producing
250-650: A Scottish inventor, built a small-scale prototype of a steam road locomotive in Birmingham . A full-scale rail steam locomotive was proposed by William Reynolds around 1787. An early working model of a steam rail locomotive was designed and constructed by steamboat pioneer John Fitch in the US during 1794. Some sources claim Fitch's model was operable already by the 1780s and that he demonstrated his locomotive to George Washington . His steam locomotive used interior bladed wheels guided by rails or tracks. The model still exists at
375-585: A barge powered by paddle wheels and several dredgers . Trevithick saw opportunities in London and persuaded his wife and four children reluctantly to join him in 1808 for two and a half years lodging first in Rotherhithe and then in Limehouse . In 1808 Trevithick entered a partnership with Robert Dickinson (businessman) , a West India merchant. Dickinson supported several of Trevithick's patents. The first of these
500-498: A reaction turbine . In 1811 draining water from the rich silver mines of Cerro de Pasco in Peru at an altitude of 4,330 metres (14,210 ft) posed serious problems for the man in charge, Francisco Uville . The low-pressure condensing engines by Boulton and Watt developed so little power as to be useless at this altitude, and they could not be dismantled into sufficiently small pieces to be transported there along mule tracks. Uville
625-635: A (newly identified) Killingworth Billy in 1816. He also constructed The Duke in 1817 for the Kilmarnock and Troon Railway , which was the first steam locomotive to work in Scotland. In 1825, Stephenson built Locomotion No. 1 for the Stockton and Darlington Railway , north-east England, which was the first public steam railway in the world. In 1829, his son Robert built in Newcastle The Rocket , which
750-448: A balance has to be struck between obtaining sufficient draught for combustion whilst giving the exhaust gases and particles sufficient time to be consumed. In the past, a strong draught could lift the fire off the grate, or cause the ejection of unburnt particles of fuel, dirt and pollution for which steam locomotives had an unenviable reputation. Moreover, the pumping action of the exhaust has the counter-effect of exerting back pressure on
875-446: A boiler feeding a hollow axle to route the steam to a catherine wheel with two fine- bore steam jets on its circumference. The first wheel was 15 feet (4.6 m) in diameter and a later attempt was 24 feet (7.3 m) in diameter. To get any usable torque , steam had to issue from the nozzles at a very high velocity and in such large volume that it proved not to operate with adequate efficiency. Today this would be recognised as
1000-403: A carriage attached. (Note this did not use the expansion of the steam, so-called "expansive working" came later) Trevithick began building his first models of high-pressure (meaning a few atmospheres ) steam engines – first a stationary one and subsequently one attached to a road carriage. A double-acting cylinder was used, with steam distribution by means of a four-way valve . Exhaust steam
1125-466: A condensing engine. He was not the first to think of so-called "strong steam" or steam of about 30 psi (210 kPa). William Murdoch had developed and demonstrated a model steam carriage, initially in 1784, and demonstrated it to Trevithick at his request in 1794. In fact, Trevithick lived next door to Murdoch in Redruth in 1797 and 1798. Oliver Evans in the U.S. had also concerned himself with
1250-593: A consultant on mining methods. The government granted him certain mining rights and he found mining areas, but did not have the funds to develop them, with the exception of a copper and silver mine at Caxatambo . After a time serving in the army of Simon Bolivar he returned to Caxatambo but due to the unsettled state of the country and presence of the Spanish army he was forced to leave the area and abandon £5,000 worth of ore ready to ship. Uville died in 1818 and Trevithick soon returned to Cerro de Pasco to continue mining. However,
1375-483: A crankpin on the driving wheel ( Main driver in the US) or to a crank on a driving axle. The movement of the valves in the steam chest is controlled through a set of rods and linkages called the valve gear , actuated from the driving axle or from the crankpin; the valve gear includes devices that allow reversing the engine, adjusting valve travel and the timing of the admission and exhaust events. The cut-off point determines

#17328449489681500-437: A deployable "water scoop" fitted under the tender or the rear water tank in the case of a large tank engine; the fireman remotely lowered the scoop into the trough, the speed of the engine forced the water up into the tank, and the scoop was raised again once it was full. Water is essential for the operation of a steam locomotive. As Swengel argued: Richard Trevithick Richard Trevithick (13 April 1771 – 22 April 1833)
1625-418: A distance of 9.75 miles (15.69 km). On 21 February 1804, amid great interest from the public, it successfully carried 10 tons of iron, five wagons and 70 men the full distance in 4 hours and 5 minutes, at an average speed of approximately 2.4 mph (3.9 km/h). As well as Homfray, Crawshay and the passengers, other witnesses included Mr. Giddy , a respected patron of Trevithick, and an "engineer from
1750-429: A gauge mounted in the cab. Steam pressure can be released manually by the driver or fireman. If the pressure reaches the boiler's design working limit, a safety valve opens automatically to reduce the pressure and avoid a catastrophic accident. The exhaust steam from the engine cylinders shoots out of a nozzle pointing up the chimney in the smokebox. The steam entrains or drags the smokebox gases with it which maintains
1875-420: A length of 1,220 feet (370 m). In August 1807, he began driving a small pilot tunnel or driftway 5 feet (1.5 m) high tapering from 2 feet 6 inches (0.76 m) at the top to 3 feet (0.91 m) at the bottom. By 23 December, after it had progressed 950 feet (290 m), progress was delayed after a sudden inrush of water; and only one month later on 26 January 1808, at 1,040 feet (320 m),
2000-820: A locomotive for £3,364 - some £497 cheaper than Phoenix's cost, and noted that Phoenix was making a 23 percent profit on each locomotive. Phoenix received no further orders from the VR beyond the seven members of the Dd class which were delivered in 1904. The works lasted another year until the directors entered voluntary liquidation . Locomotives built by the Phoenix Foundry for the Victorian Railways included: The foundry received an Engineering Heritage Marker from Engineers Australia as part of its Engineering Heritage Recognition Program . Steam locomotive A steam locomotive
2125-481: A lower pressure in the smokebox than that under the firebox grate. This pressure difference causes air to flow up through the coal bed and keeps the fire burning. The search for thermal efficiency greater than that of a typical fire-tube boiler led engineers, such as Nigel Gresley , to consider the water-tube boiler . Although he tested the concept on the LNER Class W1 , the difficulties during development exceeded
2250-433: A lower reciprocating mass than three, four, five or six coupled axles. They were thus able to turn at very high speeds due to the lower reciprocating mass. A trailing axle was able to support a huge firebox, hence most locomotives with the wheel arrangement of 4-4-2 (American Type Atlantic) were called free steamers and were able to maintain steam pressure regardless of throttle setting. The chassis, or locomotive frame ,
2375-530: A meal of roast goose and drinks. Meanwhile, the water boiled off, the engine overheated and the machine burned, destroying it. Trevithick did not consider this a serious setback, but rather operator error. In 1802 Trevithick took out a patent for his high-pressure steam engine. To prove his ideas, he built a stationary engine at the Coalbrookdale Company's works in Shropshire in 1802, forcing water to
2500-479: A measured height to measure the work done . The engine ran at forty piston strokes a minute, with an unprecedented boiler pressure of 145 psi (1,000 kPa). In 1802 the Coalbrookdale Company in Shropshire built a rail locomotive for him, but little is known about it, including whether or not it actually ran. The death of a company workman in an accident involving the engine is said to have caused
2625-518: A more serious inrush occurred. The tunnel was flooded; Trevithick, being the last to leave, was nearly drowned. Clay was dumped on the river bed to seal the hole, and the tunnel was drained, but mining was now more difficult. Progress stalled, and a few of the directors attempted to discredit Trevithick, but the quality of his work was eventually upheld by two colliery engineers from the North of England. Despite suggesting various building techniques to complete
SECTION 20
#17328449489682750-461: A new locomotive called Catch Me Who Can , built for him by John Hazledine and John Urpeth Rastrick at Bridgnorth in Shropshire , and named by Davies Giddy 's daughter. The configuration differed from the previous locomotives in that the cylinder was mounted vertically and drove a pair of wheels directly without a flywheel or gearing. This was probably Trevithick's fourth locomotive, after those used at Coalbrookdale, Pen-y-darren ironworks, and
2875-589: A non- union shop, which resulted in conflict with the employees. Further trouble arose regarding the foundry's relationships with the Victorian Railways (VR), with a tender war erupting between Phoenix and the VR Newport Workshops for the construction of Dd class 4-6-0 light-line locomotives. A Royal Commission was appointed in October 1904 to resolve the question of the 'real costs' of production. The Commission found in favour of Newport, which could produce
3000-630: A number of Swiss steam shunting locomotives were modified to use electrically heated boilers, consuming around 480 kW of power collected from an overhead line with a pantograph . These locomotives were significantly less efficient than electric ones ; they were used because Switzerland was suffering a coal shortage because of the War, but had access to plentiful hydroelectricity . A number of tourist lines and heritage locomotives in Switzerland, Argentina and Australia have used light diesel-type oil. Water
3125-456: A number of important innovations that included using high-pressure steam which reduced the weight of the engine and increased its efficiency. Trevithick visited the Newcastle area in 1804 and had a ready audience of colliery (coal mine) owners and engineers. The visit was so successful that the colliery railways in north-east England became the leading centre for experimentation and development of
3250-459: A rigid frame with a 30% weight reduction. Generally, the largest locomotives are permanently coupled to a tender that carries the water and fuel. Often, locomotives working shorter distances do not have a tender and carry the fuel in a bunker, with the water carried in tanks placed next to the boiler. The tanks can be in various configurations, including two tanks alongside ( side tanks or pannier tanks ), one on top ( saddle tank ) or one between
3375-508: A single internal fire tube or flue passing horizontally through the middle. Hot exhaust gases from the fire passed through the flue thus increasing the surface area heating the water and improving efficiency. These types were installed in the Boulton and Watt pumping engines at Dolcoath and more than doubled their efficiency. Again in 1812, he installed a new 'high-pressure' experimental condensing steam engine at Wheal Prosper. This became known as
3500-401: A tank in the locomotive tender or wrapped around the boiler in the case of a tank locomotive . Periodic stops are required to refill the tanks; an alternative was a scoop installed under the tender that collected water as the train passed over a track pan located between the rails. While the locomotive is producing steam, the amount of water in the boiler is constantly monitored by looking at
3625-521: A train along the tramway of the Penydarren Ironworks , in Merthyr Tydfil , Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica . Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of
3750-517: A wide range of products. From around 1858 the employees were working an eight-hour day while doing as much work as English workers did in ten hours. In 1871 Phoenix completed the locomotive named Governor Weld which was the first steam locomotive to operate in Western Australia. Also in August 1871 the foundry successfully tendered for the first Victorian Government railway locomotive contracts, with
3875-405: Is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam . It is fuelled by burning combustible material (usually coal , oil or, rarely, wood ) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam

4000-449: Is admitted alternately to each end of its cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in
4125-475: Is crucial to the efficiency of any steam locomotive, and the internal profiles of the chimney (or, strictly speaking, the ejector ) require careful design and adjustment. This has been the object of intensive studies by a number of engineers (and often ignored by others, sometimes with catastrophic consequences). The fact that the draught depends on the exhaust pressure means that power delivery and power generation are automatically self-adjusting. Among other things,
4250-419: Is directed upwards out of the locomotive through the chimney, by way of a nozzle called a blastpipe , creating the familiar "chuffing" sound of the steam locomotive. The blastpipe is placed at a strategic point inside the smokebox that is at the same time traversed by the combustion gases drawn through the boiler and grate by the action of the steam blast. The combining of the two streams, steam and exhaust gases,

The boiler is rigidly mounted on a "saddle" beneath the smokebox and in front of the boiler barrel, but the firebox at the rear is allowed to slide forward and backwards, to allow for expansion when hot. European locomotives usually use "plate frames", where two vertical flat plates form
4500-596: The Cornish engine , and was the most efficient in the world at that time. Other Cornish engineers contributed to its development but Trevithick's work was predominant. In the same year he installed another high-pressure engine, though non-condensing, in a threshing machine at the Trewithen Estate, a farm in Probus, Cornwall . It was very successful and proved to be cheaper to run than the horses it replaced. In use for 70 years, it
4625-874: The Drache , was delivered in 1848. The first steam locomotives operating in Italy were the Bayard and the Vesuvio , running on the Napoli-Portici line, in the Kingdom of the Two Sicilies. The first railway line over Swiss territory was the Strasbourg – Basel line opened in 1844. Three years later, in 1847, the first fully Swiss railway line, the Spanisch Brötli Bahn , from Zürich to Baden
4750-574: The Ohio Historical Society Museum in Columbus, US. The authenticity and date of this locomotive is disputed by some experts and a workable steam train would have to await the invention of the high-pressure steam engine by Richard Trevithick , who pioneered the use of steam locomotives. The first full-scale working railway steam locomotive was the 3 ft ( 914 mm ) gauge Coalbrookdale Locomotive built by Trevithick in 1802. It
4875-587: The Pennsylvania Railroad class S1 achieved speeds upwards of 150 mph, though this was never officially proven. In the United States, larger loading gauges allowed the development of very large, heavy locomotives such as the Union Pacific Big Boy , which weighs 540 long tons (550 t ; 600 short tons ) and has a tractive effort of 135,375 pounds-force (602,180 newtons). Beginning in

Richard Trevithick built the first steam locomotive known to have hauled a load over a distance at Pen-y-darren in 1804, although he produced an earlier locomotive for trial at Coalbrookdale in 1802. Salamanca , built in 1812 by Matthew Murray for the Middleton Railway ,
5125-415: The axles were mounted directly on the boiler, with no frame. On the drawing, the piston-rod, guide-bars and cross-head are located directly above the firebox door, thus making the engine extremely dangerous to fire while moving. Furthermore, the first drawing by Daniel Shute indicates that the locomotive ran on a plateway with a track gauge of 3 ft ( 914 mm ). This is the drawing used as

5250-434: The gradient was sufficiently gentle, it was possible to successfully haul heavy carriages along a smooth iron road using the adhesive weight alone of a suitably heavy and powerful steam locomotive. Trevithick's was probably the first to do so; but some of the short cast iron plates of the tramroad broke under the locomotive, because they were intended only to support the lighter axle load of horse-drawn wagons. Consequently,
5375-590: The Government". The engineer from the government was probably a safety inspector, who would have been particularly interested in the boiler's ability to withstand high steam pressures. The configuration of the Pen-y-Darren engine differed from the Coalbrookdale engine. The cylinder was moved to the other end of the boiler so that the fire door was out of the way of the moving parts. That obviously also involved putting
5500-730: The Pen-y-darren locomotive was commissioned in 1981 and delivered to the Welsh Industrial and Maritime Museum in Cardiff. When that closed, the locomotive was moved to the National Waterfront Museum in Swansea. Several times a year, it is run on a 40 m (130 ft) length of railway outside the museum. Christopher Blackett , proprietor of the Wylam colliery near Newcastle, heard of

On 7 December 1835, the Adler ran for the first time between Nuremberg and Fürth on the Bavarian Ludwig Railway . It was the 118th engine from the locomotive works of Robert Stephenson and stood under patent protection. In Russia , the first steam locomotive

Exhaust steam
5875-599: The United States, including John Fitch's miniature prototype. A prominent full sized example was Col. John Steven's "steam wagon" which was demonstrated on a loop of track in Hoboken, New Jersey in 1825. Many of the earliest locomotives for commercial use on American railroads were imported from Great Britain, including first the Stourbridge Lion and later the John Bull . However, a domestic locomotive-manufacturing industry
6000-639: The Wylam colliery. He ran it on a circular track just south of the present-day Euston Square tube station in London. The site in Bloomsbury has recently been identified archaeologically as that occupied by the Chadwick Building , part of University College London . Admission to the "steam circus" was one shilling including a ride and it was intended to show that rail travel was faster than by horse. This venture also suffered from weak tracks and public interest
6125-545: The adhesive weight. Equalising beams connecting the ends of leaf springs have often been deemed a complication in Britain, however, locomotives fitted with the beams have usually been less prone to loss of traction due to wheel-slip. Suspension using equalizing levers between driving axles, and between driving axles and trucks, was standard practice on North American locomotives to maintain even wheel loads when operating on uneven track. Locomotives with total adhesion, where all of

He was popular with the miners because of the respect they had for his father. In 1797 Trevithick married Jane Harvey of Hayle . They raised 6 children: Jane's father, John Harvey , formerly a blacksmith from Carnhell Green , formed the local foundry , Harveys of Hayle . His company became famous worldwide for building huge stationary "beam" engines for pumping water, usually from mines. Up to this time such steam engines were of

The Puffing Devil was unable to maintain sufficient steam pressure for long periods, and would have been of little practical use. He built another steam-powered road vehicle in 1803, called the London Steam Carriage , which attracted much attention from the public and press when he drove it that year in London from Holborn to Paddington and back. It

In 1802 Trevithick built one of his high-pressure steam engines to drive a hammer at the Penydarren Ironworks in Merthyr Tydfil , Mid Glamorgan . With the assistance of Rees Jones, an employee of the iron works, and under the supervision of Samuel Homfray,
6625-402: The boiler materials to the point where it needs to be rebuilt or replaced. Start-up on a large engine may take hours of preliminary heating of the boiler water before sufficient steam is available. Although the boiler is typically placed horizontally, for locomotives designed to work in locations with steep slopes it may be more appropriate to consider a vertical boiler or one mounted such that
6750-404: The boiler remains horizontal but the wheels are inclined to suit the slope of the rails. The steam generated in the boiler fills the space above the water in the partially filled boiler. Its maximum working pressure is limited by spring-loaded safety valves. It is then collected either in a perforated tube fitted above the water level or by a dome that often houses the regulator valve, or throttle,
6875-399: The boiler. Boiler water surrounds the firebox to stop the metal from becoming too hot. This is another area where the gas transfers heat to the water and is called the firebox heating surface. Ash and char collect in the smokebox as the gas gets drawn up the chimney ( stack or smokestack in the US) by the exhaust steam from the cylinders. The pressure in the boiler has to be monitored using
7000-467: The company to not proceed to running it on their existing railway. To date, the only known information about it comes from a drawing preserved at the Science Museum, London , together with a letter written by Trevithick to his friend Davies Giddy . The design incorporated a single horizontal cylinder enclosed in a return-flue boiler . A flywheel drove the wheels on one side through spur gears , and
7125-632: The concept, but there is no indication that his ideas had ever come to Trevithick's attention. Independently of this, Arthur Woolf was experimenting with higher pressures whilst working as the Chief Engineer of the Griffin Brewery (proprietors Meux and Reid). This was an Engine designed by Hornblower and Maberly, and the proprietors were keen to have the best steam engine in London. Around 1796, Woolf believed he could save substantial amounts of coal consumption. According to his son Francis, Trevithick
7250-535: The condensing or atmospheric type, originally invented by Thomas Newcomen in 1712, which also became known as low-pressure engines. James Watt , on behalf of his partnership with Matthew Boulton , held a number of patents for improving the efficiency of Newcomen's engine—including the "separate condenser patent", which proved the most contentious. Trevithick became engineer at the Ding Dong Mine in 1797, and there (in conjunction with Edward Bull ) he pioneered
7375-444: The crankshaft at the chimney end. The locomotive comprised a boiler with a single return flue mounted on a four-wheel frame. At one end, a single cylinder , with very long stroke, was mounted partly in the boiler, and a piston rod crosshead ran out along a slidebar, an arrangement that looked like a giant trombone. There was only one cylinder, which was coupled to a large flywheel mounted on one side. The rotational inertia of

Trevithick was extremely strong and was a champion Cornish wrestler . Richard Trevithick was born at Tregajorran (in the parish of Illogan ), between Camborne and Redruth , in the heart of one of the rich mineral -mining areas of Cornwall . He

Trevithick's suggestion of a submerged tube approach was successfully implemented for the first time across the Detroit River between Michigan in the United States and Ontario in Canada with the construction of the Michigan Central Railway Tunnel , under the engineering supervision of The New York Central Railway's engineering vice president, William J Wilgus . Construction began in 1903 and

#17328449489687750-675: The dominant fuel worldwide in steam locomotives. Railways serving sugar cane farming operations burned bagasse , a byproduct of sugar refining. In the US, the ready availability and low price of oil made it a popular steam locomotive fuel after 1900 for the southwestern railroads, particularly the Southern Pacific. In the Australian state of Victoria, many steam locomotives were converted to heavy oil firing after World War II. German, Russian, Australian and British railways experimented with using coal dust to fire locomotives. During World War 2,
7875-440: The early 1900s, steam locomotives were gradually superseded by electric and diesel locomotives , with railways fully converting to electric and diesel power beginning in the late 1930s. The majority of steam locomotives were retired from regular service by the 1980s, although several continue to run on tourist and heritage lines. The earliest railways employed horses to draw carts along rail tracks . In 1784, William Murdoch ,

Running gear includes the brake gear, wheel sets , axleboxes , springing and the motion that includes connecting rods and valve gear. The transmission of the power from the pistons to the rails and the behaviour of the locomotive as a vehicle, being able to negotiate curves, points and irregularities in

The development of the fusible plug , a temperature-sensitive device, ensured a controlled venting of steam into the firebox to warn the fireman to add water. Scale builds up in the boiler and prevents adequate heat transfer, and corrosion eventually degrades
8250-585: The first locomotive being delivered on 27 February 1873, and by 1884 over 350 men were employed. Modernisation of the works was carried out after Shaw visited Britain in 1871 and 1885, with the workshops becoming the most advanced in the southern hemisphere . The hundredth locomotive was completed in April 1883 and the two hundredth by October 1887. The majority of locomotives built were duplicates of imported 'pattern engines' designed and built overseas by other companies. Problems arose in 1889 when Shaw attempted to enforce
8375-418: The flywheel would even out the movement that was transmitted to a central cog-wheel that was, in turn connected to the driving wheels. It used a high-pressure cylinder without a condenser. The exhaust steam was sent up the chimney, which assisted the draught through the fire, increasing the efficiency of the engine even more. The bet was won. Despite many people's doubts, it had been shown that, provided that

In the UK and other parts of Europe, plentiful supplies of coal made this the obvious choice from the earliest days of the steam engine. Until 1870, the majority of locomotives in the United States burned wood, but as the Eastern forests were cleared, coal gradually became more widely used until it became

The fire-tube boiler has internal tubes connecting the firebox to the smokebox through which the combustion gases flow transferring heat to the water. All the tubes together provide a large contact area, called the tube heating surface, between the gas and water in
8750-577: The highly mineralised water was available, and locomotive boilers were lasting less than a quarter of the time normally expected. In the days of steam locomotion, about half the total train load was water for the engine. The line's operator, Commonwealth Railways , was an early adopter of the diesel-electric locomotive . The fire-tube boiler was standard practice for steam locomotive. Although other types of boiler were evaluated they were not widely used, except for some 1,000 locomotives in Hungary which used
8875-401: The incident was exploited relentlessly by James Watt and Matthew Boulton ( competitors and promoters of the low-pressure engine) who highlighted the perceived risks of using high-pressure steam. Trevithick's response was to incorporate two safety valves into future designs, only one of which could be adjusted by the operator. The adjustable valve comprised a disc covering a small hole at
9000-657: The locomotive ran on a circular track in the factory yard. It was the first locomotive to be built on the European mainland and the first steam-powered passenger service; curious onlookers could ride in the attached coaches for a fee. It is portrayed on a New Year's badge for the Royal Foundry dated 1816. Another locomotive was built using the same system in 1817. They were to be used on pit railways in Königshütte and in Luisenthal on

When inside cylinders are mounted between the frames, the plate frames are a single large casting that forms a major support element. The axleboxes slide up and down to give some sprung suspension, against thickened webs attached to the frame, called "hornblocks". American practice for many years
9250-509: The mainframes. Locomotives with multiple coupled-wheels on a rigid chassis would have unacceptable flange forces on tight curves giving excessive flange and rail wear, track spreading and wheel climb derailments. One solution was to remove or thin the flanges on an axle. More common was to give axles end-play and use lateral motion control with spring or inclined-plane gravity devices. Railroads generally preferred locomotives with fewer axles, to reduce maintenance costs. The number of axles required
9375-470: The moment when the valve blocks a steam port, "cutting off" admission steam and thus determining the proportion of the stroke during which steam is admitted into the cylinder; for example a 50% cut-off admits steam for half the stroke of the piston. The remainder of the stroke is driven by the expansive force of the steam. Careful use of cut-off provides economical use of steam and in turn, reduces fuel and water consumption. The reversing lever ( Johnson bar in
9500-400: The nearby village of Beacon . His cousin and associate, Andrew Vivian , steered the machine. It inspired the popular Cornish folk song " Camborne Hill ". During further tests, Trevithick's locomotive broke down three days later after passing over a gully in the road. The vehicle was left under some shelter with the fire still burning whilst the operators retired to a nearby public house for
9625-826: The original John Bull was on static display in the National Museum of American History in Washington, D.C. The replica is preserved at the Railroad Museum of Pennsylvania . The first railway service outside the United Kingdom and North America was opened in 1829 in France between Saint-Etienne and Lyon ; it was initially limited to animal traction and converted to steam traction early 1831, using Seguin locomotives . The first steam locomotive in service in Europe outside of France
9750-468: The piston in turn. In a two-cylinder locomotive, one cylinder is located on each side of the vehicle. The cranks are set 90° out of phase. During a full rotation of the driving wheel, steam provides four power strokes; each cylinder receives two injections of steam per revolution. The first stroke is to the front of the piston and the second stroke to the rear of the piston; hence two working strokes. Consequently, two deliveries of steam onto each piston face in
9875-470: The plunger-pole pump, a type of pump—with a beam engine—used widely in Cornwall's tin mines, in which he reversed the plunger to change it into a water-power engine. As his experience grew, he realised that improvements in boiler technology now permitted the safe production of high-pressure steam, which could move a piston in a steam engine on its own account, instead of using pressure near to atmospheric, in
10000-459: The project, including a submerged cast iron tube , Trevithick's links with the company ceased and the project was never actually completed. The first successful tunnel under the Thames was started by Sir Marc Isambard Brunel in 1823, 0.75 miles (1,200 m) upstream, assisted by his son Isambard Kingdom Brunel (who also nearly died in a tunnel collapse). Marc Brunel finally completed it in 1843,
10125-723: The proprietor, Trevithick mounted the engine on wheels and turned it into a locomotive. In 1803, Trevithick sold the patents for his locomotives to Samuel Homfray . Homfray was so impressed with Trevithick's locomotive that he made a bet of 500 guineas with another ironmaster, Richard Crawshay , that Trevithick's steam locomotive could haul ten tons of iron along the Merthyr Tramroad from Penydarren ( 51°45′03″N 3°22′33″W / 51.750825°N 3.375761°W / 51.750825; -3.375761 ) to Abercynon ( 51°38′44″N 3°19′27″W / 51.645567°N 3.324233°W / 51.645567; -3.324233 ),
10250-411: The purpose of which is to control the amount of steam leaving the boiler. The steam then either travels directly along and down a steam pipe to the engine unit or may first pass into the wet header of a superheater , the role of the latter being to improve thermal efficiency and eliminate water droplets suspended in the "saturated steam", the state in which it leaves the boiler. On leaving the superheater,
10375-506: The same vessel. Trevithick's home was just a few miles from Falmouth so Uville was able to meet him and tell him about the project. On 20 October 1816 Trevithick left Penzance on the whaler ship Asp accompanied by a lawyer named Page and a boilermaker bound for Peru. He was received by Uville with honour initially but relations soon broke down and Trevithick left in disgust at the accusations directed at him. He travelled widely in Peru acting as
10500-506: The ships boilers for cooking. In May 1810 Trevithick caught typhoid and nearly died. By September, he had recovered sufficiently to travel back to Cornwall by ship, and in February 1811 he and Dickinson were declared bankrupt . They were not discharged until 1814, Trevithick having paid off most of the partnership debts from his own funds. In about 1812 Trevithick designed the ‘ Cornish boiler ’. These were horizontal, cylindrical boilers with
10625-418: The side of the piston receiving steam, thus slightly reducing cylinder power. Designing the exhaust ejector became a specific science, with engineers such as Chapelon , Giesl and Porta making large improvements in thermal efficiency and a significant reduction in maintenance time and pollution. A similar system was used by some early gasoline/kerosene tractor manufacturers ( Advance-Rumely / Hart-Parr ) –
10750-504: The steam exits the dry header of the superheater and passes down a steam pipe, entering the steam chests adjacent to the cylinders of a reciprocating engine. Inside each steam chest is a sliding valve that distributes the steam via ports that connect the steam chest to the ends of the cylinder space. The role of the valves is twofold: admission of each fresh dose of steam, and exhaust of the used steam once it has done its work. The cylinders are double-acting, with steam admitted to each side of
10875-469: The steam locomotive. Trevithick continued his own steam propulsion experiments through another trio of locomotives, concluding with the Catch Me Who Can in 1808, first in the world to haul fare-paying passengers. In 1812, Matthew Murray 's successful twin-cylinder rack locomotive Salamanca first ran on the edge-railed rack-and-pinion Middleton Railway . Another well-known early locomotive
11000-482: The success in Wales and wrote to Trevithick asking for locomotive designs. These were sent to John Whitfield at Gateshead, Trevithick's agent, who in 1804 built what was probably the first locomotive to have flanged wheels. Blackett was using wooden rails for his tramway and, once again, Trevithick's machine was to prove too heavy for its track. In 1808 Trevithick publicised his steam railway locomotive expertise by building
11125-544: The success of Rocket at the 1829 Rainhill Trials had proved that steam locomotives could perform such duties. Robert Stephenson and Company was the pre-eminent builder of steam locomotives in the first decades of steam for railways in the United Kingdom, the United States, and much of Europe. Towards the end of the steam era, a longstanding British emphasis on speed culminated in a record, still unbroken, of 126 miles per hour (203 kilometres per hour) by LNER Class A4 4468 Mallard , however there are long-standing claims that
11250-445: The top of the boiler above the water level in the steam chest. The force exerted by the steam pressure was equalised by an opposite force created by a weight attached to a pivoted lever. The position of the weight on the lever was adjustable thus allowing the operator to set the maximum steam pressure. Trevithick also added a fusible plug of lead, positioned in the boiler just below the minimum safe water level. Under normal operation
11375-434: The track, is of paramount importance. Because reciprocating power has to be directly applied to the rail from 0 rpm upwards, this creates the problem of adhesion of the driving wheels to the smooth rail surface. Adhesive weight is the portion of the locomotive's weight bearing on the driving wheels. This is made more effective if a pair of driving wheels is able to make the most of its axle load, i.e. its individual share of
11500-421: The tramroad returned to horse power after the initial test run. Homfray was pleased he won his bet. The engine was placed on blocks and reverted to its original stationary job of driving hammers. In modern-day Merthyr Tydfil, behind the monument to Trevithick's locomotive, lies a stone wall, the sole remainder of the former boundary wall of Homfray's Penydarren House . A full-scale working reconstruction of
11625-433: The two cylinders generates a full revolution of the driving wheel. Each piston is attached to the driving axle on each side by a connecting rod, and the driving wheels are connected together by coupling rods to transmit power from the main driver to the other wheels. Note that at the two " dead centres ", when the connecting rod is on the same axis as the crankpin on the driving wheel, the connecting rod applies no torque to
11750-473: The use of high-pressure steam. He worked on building and modifying steam engines to avoid the royalties due to Watt on the separate condenser patent. Boulton & Watt served an injunction on him at Ding Dong, and posted it "on the minestuffs" and "most likely on the door" of the Count (Account) House which, although now a ruin, is the only surviving building from Trevithick's time there. He also experimented with
11875-419: The water level in a transparent tube, or sight glass. Efficient and safe operation of the boiler requires keeping the level in between lines marked on the sight glass. If the water level is too high, steam production falls, efficiency is lost and water is carried out with the steam into the cylinders, possibly causing mechanical damage. More seriously, if the water level gets too low, the crown sheet (top sheet) of
12000-415: The water temperature could not exceed that of boiling water and kept the lead below its melting point. If the water ran low, it exposed the lead plug, and the cooling effect of the water was lost. The temperature would then rise sufficiently to melt the lead, releasing steam into the fire, reducing the boiler pressure and providing an audible alarm in sufficient time for the operator to damp the fire, and let
12125-401: The water-tube Brotan boiler . A boiler consists of a firebox where the fuel is burned, a barrel where water is turned into steam, and a smokebox which is kept at a slightly lower pressure than outside the firebox. Solid fuel, such as wood, coal or coke, is thrown into the firebox through a door by a fireman , onto a set of grates which hold the fuel in a bed as it burns. Ash falls through
12250-408: The wheel. Therefore, if both cranksets could be at "dead centre" at the same time, and the wheels should happen to stop in this position, the locomotive could not start moving. Therefore, the crankpins are attached to the wheels at a 90° angle to each other, so only one side can be at dead centre at a time. Each piston transmits power through a crosshead , connecting rod ( Main rod in the US) and
12375-411: The wheels are coupled together, generally lack stability at speed. To counter this, locomotives often fit unpowered carrying wheels mounted on two-wheeled trucks or four-wheeled bogies centred by springs/inverted rockers/geared rollers that help to guide the locomotive through curves. These usually take on weight – of the cylinders at the front or the firebox at the rear – when the width exceeds that of
12500-406: The will to increase efficiency by that route. The steam generated in the boiler not only moves the locomotive, but is also used to operate other devices such as the whistle, the air compressor for the brakes, the pump for replenishing the water in the boiler and the passenger car heating system. The constant demand for steam requires a periodic replacement of water in the boiler. The water is kept in
12625-844: The world also runs in Austria: the GKB 671 built in 1860, has never been taken out of service, and is still used for special excursions. In 1838, the third steam locomotive to be built in Germany, the Saxonia , was manufactured by the Maschinenbaufirma Übigau near Dresden , built by Prof. Johann Andreas Schubert . The first independently designed locomotive in Germany was the Beuth , built by August Borsig in 1841. The first locomotive produced by Henschel-Werke in Kassel ,
12750-492: Was Puffing Billy , built 1813–14 by engineer William Hedley . It was intended to work on the Wylam Colliery near Newcastle upon Tyne. This locomotive is the oldest preserved, and is on static display at the Science Museum, London . George Stephenson , a former miner working as an engine-wright at Killingworth Colliery , developed up to sixteen Killingworth locomotives , including Blücher in 1814, another in 1815, and
12875-549: Was arithmetic , for which he had an aptitude, though arriving at the correct answers by unconventional means. Trevithick was the son of mine "captain" Richard Trevithick (1735–1797) and of miner's daughter Ann Teague (died 1810). As a child he would watch steam engines pump water from the deep tin and copper mines in Cornwall. For a time he was a neighbour of William Murdoch , the steam carriage pioneer, and would have been influenced by Murdoch’s experiments with steam-powered road locomotion. Trevithick first went to work at
13000-550: Was a British inventor and mining engineer . The son of a mining captain, and born in the mining heartland of Cornwall , Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive . The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled
13125-625: Was built in 1834 by Cherepanovs , however, it suffered from the lack of coal in the area and was replaced with horse traction after all the woods nearby had been cut down. The first Russian Tsarskoye Selo steam railway started in 1837 with locomotives purchased from Robert Stephenson and Company . In 1837, the first steam railway started in Austria on the Emperor Ferdinand Northern Railway between Vienna-Floridsdorf and Deutsch-Wagram . The oldest continually working steam engine in
13250-510: Was completed in 1910. The Detroit–Windsor Tunnel which was completed in 1930 for automotive traffic, and the tunnel under the Hong Kong Harbour were also submerged-tube designs. Trevithick went on to research other projects to exploit his high-pressure steam engines: boring brass for cannon manufacture, stone crushing, rolling mills, forge hammers, blast furnace blowers as well as the traditional mining applications. He also built
13375-683: Was constructed for the Coalbrookdale ironworks in Shropshire in the United Kingdom though no record of it working there has survived. On 21 February 1804, the first recorded steam-hauled railway journey took place as another of Trevithick's locomotives hauled a train along the 4 ft 4 in ( 1,321 mm )-wide tramway from the Pen-y-darren ironworks, near Merthyr Tydfil , to Abercynon in South Wales. Accompanied by Andrew Vivian , it ran with mixed success. The design incorporated
13500-411: Was dictated by the maximum axle loading of the railroad in question. A builder would typically add axles until the maximum weight on any one axle was acceptable to the railroad's maximum axle loading. A locomotive with a wheel arrangement of two lead axles, two drive axles, and one trailing axle was a high-speed machine. Two lead axles were necessary to have good tracking at high speeds. Two drive axles had
13625-480: Was entered in and won the Rainhill Trials . This success led to the company emerging as the pre-eminent builder of steam locomotives used on railways in the UK, US and much of Europe. The Liverpool and Manchester Railway opened a year later making exclusive use of steam power for passenger and goods trains . Before the arrival of British imports, some domestic steam locomotive prototypes were built and tested in
13750-471: Was limited. Trevithick was disappointed by the response and designed no more railway locomotives. It was not until 1812 that twin-cylinder steam locomotives, built by Matthew Murray in Holbeck , successfully started replacing horses for hauling coal wagons on the edge railed , rack and pinion Middleton Railway from Middleton colliery to Leeds , West Yorkshire . Robert Vazie , another Cornish engineer,
13875-679: Was named The Elephant , which on 5 May 1835 hauled a train on the first line in Belgium, linking Mechelen and Brussels. In Germany, the first working steam locomotive was a rack-and-pinion engine, similar to the Salamanca , designed by the British locomotive pioneer John Blenkinsop . Built in June 1816 by Johann Friedrich Krigar in the Royal Berlin Iron Foundry ( Königliche Eisengießerei zu Berlin),
14000-524: Was opened. The arid nature of south Australia posed distinctive challenges to their early steam locomotion network. The high concentration of magnesium chloride in the well water ( bore water ) used in locomotive boilers on the Trans-Australian Railway caused serious and expensive maintenance problems. At no point along its route does the line cross a permanent freshwater watercourse, so bore water had to be relied on. No inexpensive treatment for
14125-576: Was selected by the Thames Archway Company in 1805 to drive a tunnel under the River Thames at Rotherhithe . Vazie encountered serious problems with water influx, and had got no further than sinking the end shafts when the directors called in Trevithick for consultation. The directors agreed to pay Trevithick £1000 (the equivalent of £100,528 in 2023 ) if he could successfully complete the tunnel,
14250-459: Was sent to England to investigate using Trevithick's high-pressure steam engine. He bought one for 20 guineas, transported it back and found it to work quite satisfactorily. In 1813 Uville set sail again for England and, having fallen ill on the way, broke his journey via Jamaica . When he had recovered he boarded the Falmouth packet ship 'Fox' coincidentally with one of Trevithick's cousins on board
14375-556: Was set up at Limehouse to manufacture them, employing three men. The tanks were also used to raise sunken wrecks by placing them under the wreck and creating buoyancy by pumping them full of air. In 1810 a wreck near Margate was raised in this way but there was a dispute over payment and Trevithick was driven to cut the lashings loose and let it sink again. In 1809, Trevithick worked on various ideas on improvements for ships: iron floating docks, iron ships, telescopic iron masts, improved ship structures, iron buoys and using heat from
14500-563: Was soon established. In 1830, the Baltimore and Ohio Railroad 's Tom Thumb , designed by Peter Cooper , was the first commercial US-built locomotive to run in America; it was intended as a demonstration of the potential of steam traction rather than as a revenue-earning locomotive. The DeWitt Clinton , built in 1831 for the Mohawk and Hudson Railroad , was a notable early locomotive. As of 2021 ,
14625-403: Was supplied at stopping places and locomotive depots from a dedicated water tower connected to water cranes or gantries. In the UK, the US and France, water troughs ( track pans in the US) were provided on some main lines to allow locomotives to replenish their water supply without stopping, from rainwater or snowmelt that filled the trough due to inclement weather. This was achieved by using
14750-517: Was the Nautical Labourer ; a steam tug with a floating crane propelled by paddle wheels. However, it did not meet the fire regulations for the docks, and the Society of Coal Whippers, worried about losing their livelihood, even threatened the life of Trevithick. Another patent was for the installation of iron tanks in ships for storage of cargo and water instead of in wooden casks . A small works
14875-483: Was the first commercially successful steam locomotive. Locomotion No. 1 , built by George Stephenson and his son Robert's company Robert Stephenson and Company , was the first steam locomotive to haul passengers on a public railway, the Stockton and Darlington Railway , in 1825. Rapid development ensued; in 1830 George Stephenson opened the first public inter-city railway, the Liverpool and Manchester Railway , after
15000-461: Was the first to make high-pressure steam work in England in 1799, although other sources say he had invented his first high-pressure engine by 1797. Not only would a high-pressure steam engine eliminate the condenser, but it would allow the use of a smaller cylinder, saving space and weight. He reasoned that his engine could now be more compact, lighter, and small enough to carry its own weight even with
15125-454: Was the youngest-but-one child and the only boy in a family of six children. He was very tall for the era at 6 ft 2 in (1.88 m), as well as athletic and concentrated more on sport than schoolwork. Sent to the village school at Camborne, he did not take much advantage of the education provided; one of his school masters described him as "a disobedient, slow, obstinate, spoiled boy, frequently absent and very inattentive". An exception
15250-444: Was then retired to an exhibit at the Science Museum . In 2023, the owners of the Trewithen Estate planned to redevelop their farm, which will also involve returning the historic Trevithick steam engine to its original location within the farm. In one of Trevithick's more unusual projects, he attempted to build a 'recoil engine' similar to the aeolipile described by Hero of Alexandria in about AD 50. Trevithick's engine comprised
15375-404: Was to use built-up bar frames, with the smokebox saddle/cylinder structure and drag beam integrated therein. In the 1920s, with the introduction of "superpower", the cast-steel locomotive bed became the norm, incorporating frames, spring hangers, motion brackets, smokebox saddle and cylinder blocks into a single complex, sturdy but heavy casting. A SNCF design study using welded tubular frames gave
15500-437: Was uncomfortable for passengers and proved more expensive to run than a horse-drawn carriage, and was abandoned. In 1831, Trevithick gave evidence to a Parliamentary select committee on steam carriages. Also in 1803, one of Trevithick's stationary pumping engines in use at Greenwich exploded, killing four men. Although Trevithick considered the explosion to be caused by a case of careless operation rather than design error,
15625-736: Was vented via a vertical pipe or chimney straight into the atmosphere, thus avoiding a condenser and any possible infringements of Watt's patent. The linear motion was directly converted into circular motion via a crank instead of using a more cumbersome beam. Trevithick built a full-size steam road locomotive in 1801, on a site near present-day Fore Street in Camborne. (A steam wagon built in 1770 by Nicolas-Joseph Cugnot may have an earlier claim.) Trevithick named his carriage Puffing Devil and on Christmas Eve that year, he demonstrated it by successfully carrying six passengers up Fore Street and then continuing on up Camborne Hill, from Camborne Cross, to
