93-536: The Waikato Connection was a short-lived express passenger train between Hamilton and Auckland in New Zealand 's North Island . It consisted of a weekday single return service using diesel multiple unit railcars . Like its southern counterpart, the Capital Connection between Palmerston North and Wellington , the service was operated by Tranz Scenic and run as a commercial venture. The service
186-430: A railway track and transport people or freight . Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars . Passengers and cargo are carried in railroad cars , also known as wagons or carriages. Trains are designed to a certain gauge , or distance between rails. Most trains operate on steel tracks with steel wheels,
279-708: A third rail electric system , which is then used to power traction motors that drive the wheels. Electric traction offers a lower cost per mile of train operation but at a higher initial cost, which can only be justified on high traffic lines. Even though the cost per mile of construction is much higher, electric traction is cheaper to operate thanks to lower maintenance and purchase costs for locomotives and equipment. Compared to diesel locomotives, electric locomotives produce no direct emissions and accelerate much faster, making them better suited to passenger service, especially underground. Various other types of train propulsion have been tried, some more successful than others. In
372-612: A train driver controls the train's operation. They may also be installed on unpowered train cars known as cab or control cars , to allow for a train to operate with the locomotive at the rear. To prevent collisions or other accidents, trains are often scheduled, and almost always are under the control of train dispatchers . Historically, trains operated based on timetables ; most trains (including nearly all passenger trains), continue to operate based on fixed schedules, though freight trains may instead run on an as-needed basis, or when enough freight cars are available to justify running
465-443: A barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A loading gauge is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in
558-414: A close match between rail spacing and the configuration of the wheelsets, and the importance of the gauge was reinforced. Railways were still seen as local concerns: there was no appreciation of a future connection to other lines, and the choice of track gauge was still a pragmatic decision based on local requirements and prejudices, and probably determined by existing local designs of (road) vehicles. Thus,
651-463: A driver directly present. Around the world, various track gauges are in use for trains. In most cases, trains can only operate on tracks that are of the same gauge; where different gauge trains meet, it is known as a break of gauge . Standard gauge , defined as 1,435 mm (4 ft 8.5 in) between the rails, is the most common gauge worldwide, though both broad-gauge and narrow-gauge trains are also in use. Trains also need to fit within
744-505: A few holdouts in Europe and South America. China was the last country to fully dieselize, due to its abundant coal reserves; steam locomotives were used to haul mainline trains as late as 2005 in Inner Mongolia . Trains began to face strong competition from automobiles and freight trucks in the 1930s, which greatly intensified following World War II. After the war, air transport also became
837-564: A fixed schedule and have priority over freight trains . Passenger trains can be divided into short and long distance services. Long distance passenger trains travel over hundreds or even thousands of miles between cities. The longest passenger train service in the world is Russia's Trans-Siberian Railway between Moscow and Vladivostok , a distance of 9,289 kilometers (5,772 mi). In general, long distance trains may take days to complete their journeys, and stop at dozens of stations along their routes. For many rural communities, they are
930-595: A gauge of 5 ft 6 in ( 1,676 mm ), and the Ulster Railway of 1839 used 6 ft 2 in ( 1,880 mm ). Locomotives were being developed in the first decades of the 19th century; they took various forms, but George Stephenson developed a successful locomotive on the Killingworth Wagonway , where he worked. His designs were successful, and when the Stockton and Darlington Railway
1023-484: A locomotive) is referred to as a rake . A collection of rail vehicles may also be called a consist. A set of vehicles that are coupled together (such as the Pioneer Zephyr ) is called a trainset. The term rolling stock is used to describe any kind of railway vehicle. Trains are an evolution of wheeled wagons running on stone wagonways , the earliest of which were built by Babylon circa 2,200 BCE. Starting in

#17328552846371116-591: A means of fighting traffic congestion on highways in urban areas. Bogies, also known in North America as trucks, support the wheels and axles of trains. Trucks range from just one axle to as many as four or more. Two-axle trucks are in the widest use worldwide, as they are better able to handle curves and support heavy loads than single axle trucks. Train vehicles are linked to one another by various systems of coupling. In much of Europe, India, and South America, trains primarily use buffers and chain couplers . In
1209-615: A mile of stopping distance. As such, emphasis is on educating motorists to yield to trains at crossings and avoid trespassing. The first trains were rope-hauled, gravity powered or pulled by horses. Steam locomotives work by burning coal, wood or oil fuel in a boiler to heat water into steam, which powers the locomotive's pistons which are in turn connected to the wheels. In the mid 20th century, most steam locomotives were replaced by diesel or electric locomotives, which were cheaper, cleaner, and more reliable. Steam locomotives are still used in heritage railways operated in many countries for
1302-567: A novelty in the shape of a mixed-gauge goods train was introduced between Truro and Penzance. It was worked by a narrow-gauge engine, and behind the narrow-gauge trucks came a broad-gauge match-truck with wide buffers and sliding shackles, followed by the broad-gauge trucks. Such trains continued to run in West Cornwall until the abolition of the Broad Gauge; they had to stop or come down to walking pace at all stations where fixed points existed and
1395-400: A significant competitor for passenger trains. Large amounts of traffic shifted to these new forms of transportation, resulting in a widespread decline in train service, both freight and passenger. A new development in the 1960s was high-speed rail , which runs on dedicated rights of way and travels at speeds of 240 kilometers per hour (150 mph) or greater. The first high-speed rail service
1488-874: A single rail, while funiculars and rack railways are uniquely designed to traverse steep slopes. Experimental trains such as high speed maglevs , which use magnetic levitation to float above a guideway, are under development in the 2020s and offer higher speeds than even the fastest conventional trains. Trains which use alternative fuels such as natural gas and hydrogen are another 21st-century development. Trains can be sorted into types based on whether they haul passengers or freight (though mixed trains which haul both exist), by their weight ( heavy rail for regular trains, light rail for lighter transit systems), by their speed, by their distance (short haul, long distance , transcontinental ), and by what form of track they use. Conventional trains operate on two rails, but several other types of track systems are also in use around
1581-645: A slight variation from the nominal gauge for pragmatic reasons. The gauge is defined in imperial units , metric units or SI units. Imperial units were established in the United Kingdom by the Weights and Measures Act 1824 . The United States customary units for length did not agree with the imperial system until 1959, when one international yard was defined as 0.9144 meters and, as derived units, 1 foot (= 1 ⁄ 3 yd) as 0.3048 meter and 1 inch (= 1 ⁄ 36 yd) as 25.4 mm. The list shows
1674-414: A small proportion of the train systems in use worldwide. Almost all monorail trains use linear induction motors Track gauge In rail transport , track gauge is the distance between the two rails of a railway track . All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present
1767-595: A train. Simple repairs may be done while a train is parked on the tracks, but more extensive repairs will be done at a motive power depot . Similar facilities exist for repairing damaged or defective train cars. Maintenance of way trains are used to build and repair railroad tracks and other equipment. Train drivers , also known as engineers, are responsible for operating trains. Conductors are in charge of trains and their cargo, and help passengers on passenger trains. Brakeman , also known as trainmen, were historically responsible for manually applying brakes, though
1860-432: A variety of systems, which may include characteristics of trams, heavier passenger trains, and rapid transit systems. There are a number of specialized trains which differ from the traditional definition of a train as a set of vehicles which travels on two rails. Monorails were developed to meet medium-demand traffic in urban transit, and consist of a train running on a single rail, typically elevated. Monorails represent
1953-563: A wide variety of cargo, flatcars (also known as flat wagons ) which have flat tops to hold cargo, hopper cars which carry bulk commodities, and tank cars which carry liquids and gases. Examples of more specialized types of train cars include bottle cars which hold molten steel, Schnabel cars which handle very heavy loads, and refrigerator cars which carry perishable goods. Early train cars were small and light, much like early locomotives, but over time they have become larger as locomotives have become more powerful. A passenger train

In current practice, it is specified at a certain distance below the rail head as the inner faces of the rail head (the gauge faces ) are not necessarily vertical. Some amount of tolerance is necessarily allowed from the nominal gauge to allow for wear, etc.; this tolerance

China and Poland use standard gauge, while Central Asia and Ukraine use 1,520 mm ( 4 ft 11 + 27 ⁄ 32 in ). When individual railway companies have chosen different gauges and have needed to share a route where space on the ground is limited, mixed gauge (or dual gauge) track, in which three (sometimes four) rails are supported in

The Arbroath and Forfar Railway opened in 1838 with
3162-1006: The Rocky Mountains of North America, Central Europe and South America. Industrial railways and mine railways across the world are often narrow gauge. Sugar cane and banana plantations are mostly served by narrow gauges. Very narrow gauges of under 2 feet (610 mm) were used for some industrial railways in space-restricted environments such as mines or farms. The French company Decauville developed 500 mm ( 19 + 3 ⁄ 4 in ) and 400 mm ( 15 + 3 ⁄ 4 in ) tracks, mainly for mines; Heywood developed 15 in ( 381 mm ) gauge for estate railways . The most common minimum gauges were 15 in ( 381 mm ), 400 mm ( 15 + 3 ⁄ 4 in ), 16 in ( 406 mm ), 18 in ( 457 mm ), 500 mm ( 19 + 3 ⁄ 4 in ) or 20 in ( 508 mm ).

Train accidents sometimes occur, including derailments (when a train leaves the tracks) and train wrecks (collisions between trains). Accidents were more common in the early days of trains, when railway signal systems, centralized traffic control , and failsafe systems to prevent collisions were primitive or did not yet exist. To prevent accidents, systems such as automatic train stop are used; these are failsafe systems that apply
3627-405: The 1500s, wagonways were introduced to haul material from mines; from the 1790s, stronger iron rails were introduced. Following early developments in the second half of the 1700s, in 1804 a steam locomotive built by British inventor Richard Trevithick powered the first ever steam train. Outside of coal mines, where fuel was readily available, steam locomotives remained untried until the opening of

Freight trains remain important for the transport of bulk commodities such as coal and grain, as well as being a means of reducing road traffic congestion by freight trucks. While conventional trains operate on relatively flat tracks with two rails, a number of specialized trains exist which are significantly different in their mode of operation. Monorails operate on
3813-533: The GWR's broad gauge continued to grow. The larger railway companies wished to expand geographically, and large areas were considered to be under their control. When a new independent line was proposed to open up an unconnected area, the gauge was crucial in determining the allegiance that the line would adopt: if it was broad gauge, it must be friendly to the Great Western railway; if narrow (standard) gauge, it must favour

During this period, many locations practicality required mixed gauge operation, and in station areas the track configuration was extremely complex. This
3999-475: The United Kingdom. News of the success of steam locomotives quickly reached the United States, where the first steam railroad opened in 1829. American railroad pioneers soon started manufacturing their own locomotives, designed to handle the sharper curves and rougher track typical of the country's railroads. The other nations of Europe also took note of British railroad developments, and most countries on

These are distinct from traditional passenger trains in that they operate more frequently, typically do not share tracks with freight trains, and cover relatively short distances. Many different kinds of systems are in use globally. Rapid transit trains that operate in tunnels below ground are known as subways, undergrounds, or metros. Elevated railways operate on viaducts or bridges above

Rolling stock on the network must have running gear ( wheelsets ) that are compatible with the gauge, and therefore the gauge is a key parameter in determining interoperability, but there are many others – see below. In some cases in
4278-567: The benefits of trains for transport led to a revival in their use and importance. Freight trains are significantly more efficient than trucks, while also emitting far fewer greenhouse gas emissions per ton-mile; passenger trains are also far more energy efficient than other modes of transport. According to the International Energy Agency , "On average, rail requires 12 times less energy and emits 7–11 times less GHGs per passenger-km travelled than private vehicles and airplanes, making it

More advanced safety systems, such as positive train control , can also automatically regulate train speed, preventing derailments from entering curves or switches too fast. Modern trains have a very good safety record overall, comparable with air travel. In the United States between 2000 and 2009, train travel averaged 0.43 deaths per billion passenger miles traveled. While this

Hand brakes are still used to park cars and locomotives, but the predominant braking system for trains globally is air brakes, invented in 1869 by George Westinghouse . Air brakes are applied at once to the entire train using air hoses. For safety and communication, trains are equipped with bells , horns , and lights . Steam locomotives typically use steam whistles rather than horns. Other types of lights may be installed on locomotives and cars, such as classification lights , Mars Lights , and ditch lights . Locomotives are in most cases equipped with cabs, also known as driving compartments, where
4557-473: The closure of many rapid transit and tram systems during this time as well. Since the 1970s, governments, environmentalists , and train advocates have promoted increased use of trains due to their greater fuel efficiency and lower greenhouse gas emissions compared to other modes of land transport. High-speed rail , first built in the 1960s, has proven competitive with cars and planes over short to medium distances. Commuter rail has grown in importance since
4650-461: The continent constructed and opened their first railroads in the 1830s and 1840s, following the first run of a steam train in France in late 1829. In the 1850s, trains continued to expand across Europe, with many influenced by or purchases of American locomotive designs. Other European countries pursued their own distinct designs. Around the world, steam locomotives grew larger and more powerful throughout
4743-557: The convenience in laying it and changing its location over unimproved ground. In restricted spaces such as tunnels, the temporary way might be double track even though the tunnel will ultimately be single track. The Airport Rail Link in Sydney had construction trains of 900 mm ( 2 ft 11 + 7 ⁄ 16 in ) gauge, which were replaced by permanent tracks of 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) gauge. During World War I, trench warfare led to

#17328552846374836-411: The corresponding envelope. A structure gauge specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a railway track , usually measured at 12.7 millimetres (0.50 inches) to 15.9 millimetres (0.63 inches) below
4929-422: The distance between these rails is also referred to as the track gauge. The earliest form of railway was a wooden wagonway, along which single wagons were manhandled, almost always in or from a mine or quarry. Initially the wagons were guided by human muscle power; subsequently by various mechanical methods. Timber rails wore rapidly: later, flat cast-iron plates were provided to limit the wear. In some localities,
5022-448: The earliest days of railways, the railway company saw itself as an infrastructure provider only, and independent hauliers provided wagons suited to the gauge. Colloquially the wagons might be referred to as "four-foot gauge wagons", say, if the track had a gauge of four feet. This nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at

These successful diesel locomotives showed that diesel power was superior to steam, due to lower costs, ease of maintenance, and better reliability. Meanwhile, Italy developed an extensive network of electric trains during

A considerable progressive step was made when cast iron edge rails were first employed; these had the major axis of the rail section configured vertically, giving a much stronger section to resist bending forces, and this was further improved when fish-belly rails were introduced. Edge rails required
5394-713: The first train powered by electricity in 1879, and went on to pioneer electric trams . Another German inventor, Rudolf Diesel , constructed the first diesel engine in the 1890s, though the potential of his invention to power trains was not realized until decades later. Between 1897 and 1903, tests of experimental electric locomotives on the Royal Prussian Military Railway in Germany demonstrated they were viable, setting speed records in excess of 160 kilometers per hour (100 mph). Early gas powered " doodlebug " self-propelled railcars entered service on railroads in
5487-404: The gauge selection was pragmatic: the track would have to fit the rolling stock. If locomotives were imported from elsewhere, especially in the early days, the track would be built to fit them. In some cases standard gauge was adopted, but many countries or companies chose a different gauge as their national gauge, either by governmental policy, or as a matter of individual choice. Standard gauge

The broad gauge network was eventually converted—a progressive process completed in 1892, called gauge conversion . The same Act mandated the gauge of 5 ft 3 in ( 1,600 mm ) for use in Ireland. As railways were built in other countries,

The wagons were built to a consistent pattern and the track would be made to suit the needs of the horses and wagons: the gauge was more critical. The Penydarren Tramroad of 1802 in South Wales, a plateway, spaced these at 4 ft 4 in ( 1,321 mm ) over the outside of the upstands. The Penydarren Tramroad probably carried

Beginning in the 1920s, and accelerating following World War II , diesel and electric locomotives replaced steam as the means of motive power. Following the development of cars , trucks , and extensive networks of highways which offered greater mobility, as well as faster airplanes , trains declined in importance and market share, and many rail lines were abandoned. The spread of buses led to
6045-480: The leisure and enthusiast market. Diesel locomotives are powered with a diesel engine, which generates electricity to drive traction motors. This is known as a diesel–electric transmission , and is used on most larger diesels. Diesel power replaced steam for a variety of reasons: diesel locomotives were less complex, far more reliable, cheaper, cleaner, easier to maintain, and more fuel efficient. Electric trains receive their current via overhead lines or through
6138-552: The local dominant gauge in use. In 1840s, the 1,600 mm ( 5 ft 3 in ) Irish gauge was considered a medium gauge compared to Brunel's 7 ft 1 ⁄ 4 in ( 2,140 mm ) broad gauge and the 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) narrow gauge, which became the modern standard gauge . In modern usage, the term "narrow gauge" generally refers to track spaced significantly narrower than 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ). Narrow gauge

Trains have their roots in wagonways , which used railway tracks and were powered by horses or pulled by cables . Following the invention of the steam locomotive in the United Kingdom in 1802, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in
6324-715: The mid 1900s, gas turbine locomotives were developed and successfully used, though most were retired due to high fuel costs and poor reliability. In the 21st century, alternative fuels for locomotives are under development, due to increasing costs for diesel and a desire to reduce greenhouse gas emissions from trains. Examples include hydrail (trains powered by hydrogen fuel cells) and the use of compressed or liquefied natural gas . Train cars, also known as wagons, are unpowered rail vehicles which are typically pulled by locomotives. Many different types exist, specialized to handle various types of cargo. Some common types include boxcars (also known as covered goods wagons ) that carry

As such, rail transport is considered an important part of achieving sustainable energy . Intermodal freight trains, carrying double-stack shipping containers , have since the 1970s generated significant business for railroads and gained market share from trucks. Increased use of commuter rail has also been promoted as

In rare situations, three different gauges may converge on to a rail yard and triple-gauge track is needed to meet the operational needs of the break-of-gauge station – most commonly where there is insufficient space to do otherwise. Construction and operation of triple-gauge track and its signalling, however, involves immense cost and disruption, and
6603-533: The only form of public transportation available. Short distance or regional passenger trains have travel times measured in hours or even minutes, as opposed to days. They run more frequently than long distance trains, and are often used by commuters. Short distance passenger trains specifically designed for commuters are known as commuter rail . High speed trains are designed to be much faster than conventional trains, and typically run on their own separate tracks than other, slower trains. The first high speed train
6696-416: The other companies. The battle to persuade or coerce that choice became very intense, and became referred to as "the gauge wars" . As passenger and freight transport between the two areas became increasingly important, the difficulty of moving from one gauge to the other—the break of gauge —became more prominent and more objectionable. In 1845 a Royal Commission on Railway Gauges was created to look into
6789-418: The plates were made L-shaped, with the vertical part of the L guiding the wheels; this is generally referred to as a "plateway". Flanged wheels eventually became universal, and the spacing between the rails had to be compatible with that of the wagon wheels. As the guidance of the wagons was improved, short strings of wagons could be connected and pulled by teams of horses, and the track could be extended from
6882-535: The respective dimensions. In modern usage the term "standard gauge" refers to 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ). Standard gauge is dominant in a majority of countries, including those in North America, most of western Europe, North Africa, the Middle East, and China. In modern usage, the term "broad gauge" generally refers to track spaced significantly wider than 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ). Broad gauge
6975-712: The rest of the century as technology advanced. Trains first entered service in South America, Africa, and Asia through construction by imperial powers , which starting in the 1840s built railroads to solidify control of their colonies and transport cargo for export. In Japan, which was never colonized, railroads first arrived in the early 1870s. By 1900, railroads were operating on every continent besides uninhabited Antarctica. Even as steam locomotive technology continued to improve, inventors in Germany started work on alternative methods for powering trains. Werner von Siemens built
7068-547: The rest of the world, Janney couplers are the most popular, with a few local variations persisting (such as Wilson couplers in the former Soviet Union). On multiple units all over the world, Scharfenberg couplers are common. Because trains are heavy, powerful brakes are needed to slow or stop trains, and because steel wheels on steel rails have relatively low friction, brakes must be distributed among as many wheels as possible. Early trains could only be stopped by manually applied hand brakes, requiring workers to ride on top of
7161-416: The same track structure, can be necessary. The most frequent need for such track was at the approaches to city terminals or at break-of-gauge stations. Tracks of multiple gauges involve considerable costs in construction (including signalling work) and complexities in track maintenance, and may require some speed restrictions. They are therefore built only when absolutely necessary. If the difference between
7254-611: The service was reported to be "performing up to expectations" and was later extended beyond the trial period. Tranz Rail announced in October 2000 that it intended to exit the passenger rail business to concentrate on its freight interests. The new owner of Tranz Scenic, two directors of West Coast Railway in Australia, had limited purchase funds, and so were only prepared to purchase the most profitable services, prompting Tranz Rail to terminate those services that were not purchased, including
7347-763: The term is used today to refer to crew members who perform tasks such as operating switches, coupling and uncoupling train cars, and setting handbrakes on equipment. Steam locomotives require a fireman who is responsible for fueling and regulating the locomotive's fire and boiler. On passenger trains, other crew members assist passengers, such as chefs to prepare food, and service attendants to provide food and drinks to passengers. Other passenger train specific duties include passenger car attendants, who assist passengers with boarding and alighting from trains, answer questions, and keep train cars clean, and sleeping car attendants, who perform similar duties in sleeping cars . Some trains can operate with automatic train operation without
7440-595: The time had a policy of not subsidising rail services, decided against providing funding at $ 400,000 pa, which was deemed to be too expensive. An approach was also made to the government for funding, especially in light of the subsidy that they had extended for the Southerner , but this was also declined. Tranz Scenic reported that the Waikato Connection was "the most unprofitable service" but that they would be prepared to consider retaining it with community support which they expected would be needed for about three years. At
7533-399: The time of its cancellation the Waikato Connection was being patronised by an average of 129 passengers per trip, most of whom boarded at Pukekohe or Papakura, with only about 30 of those travelling the full distance between Hamilton and Auckland. Some considered the cancellation premature as the service was beginning to grow in popularity. A refurbished NZR RM class (88 seater) nicknamed
7626-406: The top of the rail head in order to clear worn corners and allow for rail heads having sloping sides. The term derives from the "gauge", a metal bar with a precisely positioned lug at each end that track crews use to ensure the actual distance between the rails lies within tolerances of a prescribed standard: on curves, for example, the spacing is wider than normal. Deriving from the name of the bar,
7719-612: The two gauges is large enough – for example between 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) standard gauge and 3 ft 6 in ( 1,067 mm ) – three-rail dual-gauge is possible, but if not – for example between 3 ft 6 in ( 1,067 mm ) and 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) metre gauge – four rails must be used. Dual-gauge rail lines occur (or have occurred) in Argentina, Australia, Brazil, Japan, North Korea, Spain, Switzerland, Tunisia and Vietnam. On
7812-540: The world, such as monorail . The railway terminology that is used to describe a train varies between countries. The International Union of Railways seeks to provide standardised terminology across languages. The Association of American Railroads provides terminology for North America. The British Rail Safety and Standards Board defines a train as a "light locomotive, self-propelled rail vehicle or road-rail vehicle in rail mode." A collection of passenger or freight carriages connected together (not necessarily with
7905-441: Was compounded by the common rail having to be at the platform side in stations; therefore, in many cases, standard-gauge trains needed to be switched from one side of the track to the other at the approach. A special fixed point arrangement was devised for the purpose, where the track layout was simple enough. In some cases, mixed gauge trains were operated with wagons of both gauges. For example, MacDermot wrote: In November 1871
7998-540: Was exported to European countries and parts of North America, also using standard gauge. Britain polarised into two areas: those that used broad gauge and those that used standard gauge. In this context, standard gauge was referred to as "narrow gauge" to indicate the contrast. Some smaller concerns selected other non-standard gauges: the Eastern Counties Railway adopted 5 ft ( 1,524 mm ). Most of them converted to standard gauge at an early date, but
8091-865: Was higher than that of air travel at 0.07 deaths per billion passenger miles, it was also far below the 7.28 deaths per billion passenger miles of car travel. In the 21st century, several derailments of oil trains caused fatalities, most notably the Canadian Lac-Mégantic rail disaster in 2013 which killed 47 people and leveled much of the town of Lac-Mégantic . The vast majority of train-related fatalities, over 90 percent, are due to trespassing on railroad tracks, or collisions with road vehicles at level crossings . Organizations such as Operation Lifesaver have been formed to improve safety awareness at railroad crossings, and governments have also launched ad campaigns. Trains cannot stop quickly when at speed; even an emergency brake application may still require more than
8184-571: Was opened in 1825, it used his locomotives, with the same gauge as the Killingworth line , 4 ft 8 in ( 1,422 mm ). The Stockton and Darlington line was very successful, and when the Liverpool and Manchester Railway , the first intercity line, was opened in 1830, it used the same gauge. It too was very successful, and the gauge, widened to 4 ft 8 + 1 ⁄ 2 in or 1,435 mm and named " standard gauge ",
8277-525: Was originally impossible; goods had to be transshipped and passengers had to change trains. This was obviously a major obstacle to convenient transport, and in Great Britain, led to political intervention. On narrow gauge lines, rollbocks or transporter wagons are used: standard gauge wagons are carried on narrow gauge lines on these special vehicles, generally with rails of the wider gauge to enable those vehicles to roll on and off at transfer points. On
8370-407: Was restored in 2021 for a five-year trial as " Te Huia " . The service commenced as a six-month trial on 26 June 2000 and was primarily aimed at business people who regularly commuted to work in Auckland. It used Silver Fern railcars with full onboard catering and stopped at the intermediate stations of Huntly , Pukekohe , Papakura , Middlemore , and Newmarket . Four months into the trial
8463-544: Was the Japanese Shinkansen , which entered service in 1964. In the following decades, high speed rail networks were developed across much of Europe and Eastern Asia, providing fast and reliable service competitive with automobiles and airplanes. The first high-speed train in the Americas was Amtrak 's Acela in the United States, which entered service in 2000. Towards the end of the 20th century, increased awareness of
8556-538: Was the Japanese Shinkansen , which opened in 1964. In the 21st century, services such as the French TGV and German Intercity Express are competitive with airplanes in travel time over short to medium distances. A subset of high speed trains are higher speed trains , which bridge the gap between conventional and high speed trains, and travel at speeds between the two. Examples include the Northeast Regional in
8649-542: Was well on its way to becoming the established norm. The Liverpool and Manchester was quickly followed by other trunk railways, with the Grand Junction Railway and the London and Birmingham Railway forming a huge preponderance of standard gauge . When Bristol promoters planned a line from London, they employed the innovative engineer Isambard Kingdom Brunel . He decided on a wider gauge, to give greater stability, and
