A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU.
A train 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, though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. Trains are designed to 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.
A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control.

British Rail Class 503 passenger trains were 65 mph (105 km/h) electric multiple units. They were introduced in two batches: the first were in 1938, by the London, Midland and Scottish Railway (LMS), with a further batch in 1956 by the then nationalised British Railways (BR). When introduced by the LMS, they were known officially as Class AM3. They were designed for, and operated on, the Wirral & Mersey lines from Liverpool to West Kirby, New Brighton and Rock Ferry. There were few places on their network of closely-spaced stations to attain their maximum speed, except for the open section between Moreton and Meols. All but one set were withdrawn and scrapped by 1985. The final set was used on special Merseyrail services until 1988; it was preserved and kept at the Electric Railway Museum near Coventry, until it moved on to the Locomotive Storage Ltd warehouse at Margate.
