A train (from Old French trahiner, from Latin trahere, "to pull, to draw") [1] 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.
A railroad car, railcar (American and Canadian English), [a] railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck (British English and UIC), also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport network (a railroad/railway).
A train is a connected series of rail vehicles that move along the track. Propulsion for the train is provided by a separate locomotive or from individual motors in self-propelled multiple units. Most trains carry a revenue load, although non-revenue cars exist for the railway's own use, such as for maintenance-of-way purposes.
The SA3 coupler is one of the strongest couplers in the world – maximum tonnage of a train that uses this type of coupler is about 8000 t [31] – but provides only mechanical coupling. [24] Adding automatic electrical and pneumatic connectivity is a complex challenge. [32] There are many variations and brand names for these couplers.
Map of the world with rail density (length of rail network divided by area of country) highlighted. This does not necessarily reflect actual rail use. This is a list of countries by rail usage. Usage of rail transport may be measured in tonne-kilometres (tkm) or passenger-kilometres (pkm) travelled for freight and passenger transport ...
The Austro-Hungarian Ganz Works built steam trams prior to the First World War. The Santa Fe Railway built a steam powered rail car using a body by American Car and Foundry, a Jacobs-Schupert boiler and a Ganz power truck in 1911. Numbered M-104, the experiment was a failure, and was not repeated.
Flexible tubes made of alternate layers of rubber and canvas by which the brake pipes under engines, tenders, and cars are connected together, and compressed air, which operates the brakes, conducted through the train. The hose is made with a coupling at each end of the engine and tender so that it can readily be connected or disconnected.
High-speed trains are made up of cars from a single manufacturer and usually of a uniform design (although the dining car on the German ICE 1 has a dome). In the 1960s and 1970s countries around the world started to develop trains capable of traveling in the 150–200 mph range, to rival air travel.
