This article is about the early type of push-pull train. For other uses, see Autotrain (disambiguation).
A preserved GWR autotrain, running with the locomotive sandwiched between two driving coaches on the South Devon Railway.
The Autotrain was a type of passenger train used in the early 20th century, where the steam locomotive could be remotely controlled from the rear of the train. This meant that the engine would not have to run-around at the end of a journey before returning. These trains were also known as motor trains or railmotors at the time, but the term railmotor is now used to refer to trains where the steam engine was integrated into the coach.
A driving cab in the rearmost coach (known as an autocoach or auto trailer) has controls to allow the driver to operate the regulator, brake and whistle when driving the train 'in reverse'. The fireman would remain on the engine in order to stoke the fire and to take off the brakes, as the driver could only apply them.
Autotrains could operate with one or two coaches: either with the locomotive at the front or rear of the formation, or sandwiched between the two driving coaches.
Autotrains were being used by most rail companies in Great Britain by the 1920s, and were particularly common on branch line services. They remained in widespread use until the 1950s and 1960s, when they were replaced by diesel multiple units (DMUs). They were in effect the ancestor of the modern driving trailers.
A railcar is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach, with a driver's cab at one or both ends. Some railway companies, such as the Great Western, termed such vehicles "railmotors".
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by air brakes.
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels.
London Underground rolling stock includes the electric multiple-unit trains used on the London Underground. These come in two sizes, smaller deep-level tube trains and larger sub-surface trains of a similar size to those on British main lines, both running on standard gauge tracks. New trains are designed for the maximum number of standing passengers and for speed of access to the cars.
The Lancashire and Yorkshire Railway (LYR) built suburban electric stock for lines in Liverpool and Manchester. The line between Liverpool to Southport began using electric multiple units (EMUs) on 22 March 1904, using a third rail 625 V DC. Additional trains were later built for this route, and in 1913 incompatible stock for the route to Ormskirk. Lightweight units were built to run on the Liverpool Overhead Railway.
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not.
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail.
Electric locomotives were first used on the London Underground when the first deep-level tube line, the City and South London Railway (C&SLR), was opened in 1890. The first underground railways in London, the Metropolitan Railway (MR) and the District Railway (DR), used specially built steam locomotives to haul their trains through shallow tunnels which had many ventilation openings to allow steam and smoke to clear from the tunnels. It was impractical to use steam locomotives in the small unvented tubular tunnels of the deep-level lines, and the only options were rope haulage or electric locomotives.
The GWR Autocoach is a type of coach that was used by the Great Western Railway for push-pull trains powered by a steam locomotive. The distinguishing design feature of an autocoach is the driving cab at one end, allowing the driver to control the train without needing to be located in the cab of the steam locomotive. This eliminates the need to run the engine round to the other end of the coach at the end of each journey.
A control car, cab car, control trailer, or driving trailer is a non-powered rail vehicle from which a train can be operated. As dedicated vehicles or regular passenger cars, they have one or two driver compartments with all the controls and gauges required to remotely operate the locomotive, including exterior locomotive equipment such as horns, bells, ploughs, and lights. They also have communications and safety systems such as GSM-R or European Train Control System (ETCS). Control cars enable push-pull operation when located on the end of a train opposite its locomotive by allowing the train to reverse direction at a terminus without moving the locomotive or turning the train around.
The Bristol and Exeter Railway Fairfield was an experimental broad gauge self-propelled steam carriage. In later use the carriage portion was removed and it was used as a small shunting locomotive.
Railmotor is a term used in the United Kingdom and elsewhere for a railway lightweight railcar, usually consisting of a railway carriage with a steam traction unit, or a diesel or petrol engine, integrated into it.
The steam rail motors (SRM) were self-propelled carriages operated by the Great Western Railway in England and Wales from 1903 to 1935. They incorporated a steam locomotive within the body of the carriage.
The Henschel-Wegmann Train was an advanced passenger express train operated by the Deutsche Reichsbahn in Germany, which ran non-stop express services between Berlin and Dresden from June 1936 to August 1939. Both the DRG Class 61 steam locomotive at its head as well as the coaches were streamlined.
Metropolitan Railway electric multiple units were used on London's Metropolitan Railway after the lines were electrified in the early 20th century.
Diesel multiple units and railcars are trains, usually with passenger accommodation, that do not require a locomotive. Railcars can be single cars, while in multiple units cars are marshalled together with a driving position either end. As of December 2010, 23 percent of the rail passenger cars used on Network Rail are part of a diesel multiple unit.
A steam railcar is a rail vehicle that does not require a locomotive as it contains its own steam engine. The first steam railcar was an experimental unit designed and built in 1847 by James Samuel and William Bridges Adams. In 1848, they made the Fairfield steam carriage that they sold to the Bristol and Exeter Railway, who used it for two years on a branch line.
The CSAR Railmotor of 1907 was a South African steam railmotor locomotive from the pre-Union era in Transvaal Colony.
The Cape Government Railways Railmotor of 1906 was a South African steam railmotor locomotive from the pre-Union era in the Cape of Good Hope.
The Ballymacarrett rail crash occurred on 10 January 1945 at 7:50am in the Ballymacarrett area of Belfast, County Down, Northern Ireland on the Belfast to Bangor Line of the Belfast and County Down Railway, when a train led by a heavy autotrain driving trailer ran into the back of a stopped passenger train consisting of lightweight wooden coaches. 22 died with 27 injured. It was the worst crash in Northern Ireland since 1889. The cause was found to be carelessness of the driver of the autotrain who was running too fast for conditions. Fog, unsafe railway rules, and possible distraction from passengers all may have contributed to the accident. Old lightweight rolling stock contributed to the great number of injuries and deaths. The accident led to the demise of the railway which was nationalised three years later.
