The chain (abbreviated ch) is a unit of length equal to 66 feet (22 yards), used in both the US customary and Imperial unit systems. It is subdivided into 100 links. [1][2] There are 10 chains in a furlong, and 80 chains in one statute mile. [2] In metric terms, it is 20.1168 m long. [2] By extension, chainage (running distance) is the distance ...
Rail transport. A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train.
Buffers and chain couplers are an assembly of several devices: buffers, [1] hooks and links, or turnbuckle screws. [2] Screwlink coupler and buffers – the UIC de facto standard in the EU and UK – on a British diesel locomotive. On the modern version of the couplers, rail vehicles are mated by manually connecting the end link of one chain ...

Rail transport. Rail transport terms are a form of technical terminology applied to railways. Although many terms are uniform across different nations and companies, they are by no means universal, with differences often originating from parallel development of rail transport systems in different parts of the world, and in the national origins ...
Rail transport. Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. [1] Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, [2 ...
v. t. e. 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.
