69-600: The Dennis Domino was a step-entrance midibus chassis manufactured by Dennis in Guildford , England in 1984 and 1985. It was in essence, a scaled down single-decker version of the Dennis Dominator . Developed for intensive urban work, the Domino was fitted with Perkins T6.354.4 turbocharged engine, Maxwell automatic transmission, front radiator, full air suspension and power steering. It can be regarded as
138-708: 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
207-612: 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
276-479: A certain gauge , or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. 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
345-463: 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
414-516: 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
483-564: 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
552-522: A flat floor ranging between 760 and 1,370 mm (30 and 54 in) above the top of the railhead (ATOR). To enhance accessibility and optimize dwell times , railway platform heights at stations are sometimes standardised to allow level boarding for commuters on high platforms. According to one definition, level boarding means the gap between the platform and the floor of the track varies by no more than 76 mm (3 in) horizontally and 16 mm ( 5 ⁄ 8 in) vertically. Level boarding
621-491: 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
690-598: 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
759-615: 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

This form of design and construction will avoid the need for subsequent rebuilding of stops on tram routes, even though both cities already have underground lines with high-floor platforms. Buses in the UK were traditionally step-entrance built, however this has created problems for people who use wheelchairs as
897-408: A predecessor of the successful Dennis Dart . It was only sold to two customers, Greater Manchester Transport and South Yorkshire Transport . The Dominos for Greater Manchester Transport were bodied by Northern Counties , and South Yorkshire Transport's by Optare . In 1983, Greater Manchester Passenger Transport Executive (GMPTE) realised its nine-year-old Seddon Pennine midibuses in use on
966-434: A railcar more rapidly if they do not have to climb stairs to enter, reducing dwell time at a stop, and reducing overall travel time. In addition, high-platform railcars have more floor space for passengers if space is not required for stairways, and wheelwells needed to accommodate train bogies . Because bilevel rail cars have two passenger levels within a standard height rail car, the lower level, where passengers board,
1035-400: 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
1104-874: 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
1173-595: 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
1242-432: 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
1311-563: 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
1380-717: Is also known as stepless entry since passengers do not have to negotiate a staircase to board the passenger car. For newly constructed routes, routes primarily located in tunnels, or routes with a dedicated right of way and enough space, high platforms are usually preferred, since high-floor vehicles are cheaper to manufacture, and have better operating characteristics. High platforms do have significant advantages beyond level boarding for wheelchair accessibility. Physically disabled passengers (e.g. those using wheelchairs or who have difficulties climbing stairs) also benefit, as do travelers pulling wheeled luggage or small folding shopping carts. Even physically non-disabled passengers can board
1449-430: Is generally lower than a conventional high-floor car. Hence level boarding with a bilevel car is accomplished using a lower platform, as low as 460 mm (18 in) ATOR. Because tram/light-rail/streetcar vehicles often share loading gauge sizes with heavy rail vehicles, these passenger vehicles usually also use high floor designs. Existing tram/streetcar/light-rail networks generally feature low platforms as many of

In contrast with some light rail underground lines, which are often provisionally equipped with low platforms or with tracks laid on raised ballast, there are new developments in the German cities of Düsseldorf (Wehrhahn line) and Dortmund (east–west line). In each of these cities,

These trains may consist of unpowered passenger railroad cars (also known as coaches or carriages) hauled by one or more locomotives, or may be self-propelled; self propelled passenger trains are known as multiple units or railcars . Passenger trains travel between stations or depots , where passengers may board and disembark. In most cases, passenger trains operate on

France, Russia, Switzerland, and Japan were leaders in adopting widespread electrified railroads, while other nations focused primarily on dieselization . By 1980, the majority of the world's steam locomotives had been retired, though they continued to be used in parts of Africa and Asia, along with
1863-507: The Stockton and Darlington Railway in 1825. British engineer George Stephenson ran a steam locomotive named Locomotion No. 1 on this 40-kilometer (25-mile) long line, hauling over 400 passengers at up to 13 kilometers per hour (8 mph). The success of this locomotive, and Stephenson's Rocket in 1829, convinced many of the value in steam locomotives, and within a decade the stock market bubble known as " Railway Mania " started across
1932-640: The loading gauge profile to avoid fouling bridges and lineside infrastructure with this being a potential limiting factor on loads such as intermodal container types that may be carried. 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
2001-405: 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
2070-570: The 1960s. The 20 GMPTE Dominos with Ken Mortimer-designed Northern Counties bodies entered service in late 1985. One was demonstrated for an extended period early in 1986 to London Transport in a version of their livery, but the only other customer for the type was the South Yorkshire Passenger Transport Executive (SYPTE), who wanted to replace a batch of second-hand Bristol LHs on services reaching into more inaccessible areas of Sheffield . Whereas

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

Nothing was at that time readily available that would meet the PTE's requirements and Dennis was requested to provide a solution. This used a very-short-wheelbase version of the Dominator frame, with the optional air-over leaf suspension to axles with 16-inch wheels and low profile tyres, overall body length
2346-482: 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
2415-790: The United States, the Gatimaan Express in India, and the KTM ETS in Malaysia. A number of types of trains are used to provide rapid transit to urban areas. 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
2484-578: 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

Despite low-floor buses first being phased into the UK in 1994, a large number of step-entrance buses remained in use as well as being manufactured. However with the popularity of low-floor buses expanding by the late 1990's due to their easy accessibility for elderly passengers with reduced mobility, passengers with disabilities and parents carrying prams and pushchairs,

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

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
2829-465: 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

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

In many systems, two or even all three of these types may exist on different portions of a network. Trams, also known in North America as streetcars, typically operate on or parallel to streets in cities, with frequent stops and a high frequency of service. Light rail is a catchall term for
3381-404: The interior floor of these vehicles. The term is used in contrast with low-floor designs, which offer a decreased floor and entry height above the street surface. Since low-floor designs generally were developed after high-floor vehicles, the older high-floor design is sometimes also known as conventional or the “traditional” design. A rail vehicle of conventional or high-floor design usually has
3450-473: The interior flooring of commuter vehicles primarily used in public transport such as trains , light rail cars and other rail vehicles, along with buses and trolleybuses . Interior floor height is generally measured above the street surface or above the top of the rail. High-floor designs usually result from packaging requirements: mechanical items such as axles, motors, crankshafts, and/or transmissions, or luggage storage spaces are traditionally placed under
3519-480: 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

In San Francisco , the Muni Metro light-rail system, which has both on-street and underground stations, uses a combination of high and low platforms, and the vehicles feature retractable stairs to accommodate both platform types. For on-street stations, stairs are deployed within
3657-715: 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
3726-502: The most efficient mode of motorised passenger transport. Aside from shipping, freight rail is the most energy-efficient and least carbon-intensive way to transport goods." 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
3795-533: 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
3864-541: The production of step-entrance buses slowed, with the last ever non-compliant step-entrance bus design being the double-decked East Lancs Pyoneer in 1997. The production of step-entrance buses in the UK almost fully ceased by 31 December 2000, with the legal requirement for new buses produced to be wheelchair accessible, which forced bus manufacturers to concentrate on making low-floor buses, however bus operators were still allowed to order secondhand non-compliant step-entrance buses and run them on their services until they reach

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
4002-547: 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
4071-550: The retrofitting of high platforms on existing routes, while still providing improved accessibility. Although low-floor vehicles began to be developed in the 1920s, the first low-floor tram is generally recognized as the Duewag / ACM Vevey design of 1984 deployed in Geneva, providing a floor height of 480 mm (19 in) ATOR. Tourist coaches generally have very high floors, sometimes greater than 1,000 mm (39 in) above
4140-591: The road surface, in order to have ample room for luggage under the floor. Since boarding must be allowed directly from flat ground, long and steep staircases are needed. Transit buses also use high floors to provide mechanical clearances for solid axles, but the use of dropped axles has enabled the creation of low-floor buses and by 2008 in the United States, the majority of new transit bus orders were for low-floor types. Today, in Germany, all rapid transit railways, most commuter trains , and many light rail vehicles operate as high-floor networks. A notable exception
4209-440: The stations or stops are in the streets. The high construction/conversion cost of high platforms and the difficulty of making high platforms compatible with other features of the urban landscape are a significant obstacle to converting tram networks these into urban or commuter rail networks with high platforms. These problems were a major motivation for the development of low-floor trams , which allow transit operators to avoid

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

Train A train (from Old French trahiner , from Latin trahere , "to pull, to draw" ) is a series of connected vehicles that run along 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
4416-636: 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 the late 1800s to transport large numbers of people in and around cities. 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

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
