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.
Pacer was the operational name of the British Rail Classes 140, 141, 142, 143 and 144 diesel multiple unit railbuses built between 1980 and 1987. They were inexpensively developed using a passenger body based on the Leyland National bus on top of a chassis based on the HSFV1 research vehicle. The railbuses were intended as a short-term solution to a shortage of rolling stock, with a lifespan of no more than twenty years. As modernised replacements were lacking, the Pacer fleet remained in service on some lines until 2021, 37 years after their 1984 introduction.

The Greenford branch line is a 2 miles 40 chains (4.0 km) Network Rail suburban railway line in west London, England. It runs northerly from a triangular junction with the Great Western Main Line west of West Ealing to a central bay platform at Greenford station, where it has cross-platform interchanges to the London Underground's Central line. A triangular junction near Greenford connects to the Acton–Northolt line. The line serves mainly the suburbs of Ealing and Greenford.
The London Underground D78 Stock, commonly referred to as D Stock, was a type of sub-surface rolling stock which operated on the District line of the London Underground, except on the Wimbledon to Edgware Road service. The first units were withdrawn in January 2015 with the last withdrawn on 21 April 2017.

A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system (RESS), placed between the power source and the traction transmission system connected to the wheels. Since most diesel locomotives are diesel-electric, they have all the components of a series hybrid transmission except the storage battery, making this a relatively simple prospect.
A battery electric multiple unit (BEMU), battery electric railcar or accumulator railcar is an electrically driven multiple unit or railcar whose energy can be supplied from rechargeable batteries driving the traction motors.
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.

The British Rail Class 802 is a type of high-speed bi-mode multiple-unit passenger train designed and produced by the Japanese manufacturer Hitachi Rail. It has been operated by Great Western Railway, TransPennine Express, and Hull Trains; each of these train operating companies has given its own units a unique brand: Great Western Railway's units are branded Intercity Express Trains (IETs), TransPennine Express units are branded Nova 1s and Hull Trains' units are branded Paragons.
Although the railway network in Great Britain has some of the smallest loading gauges in the world, the vast bulk of it is still capable of operating full sized vehicles. However, British Rail, together with its predecessors and successors have, on occasion, been required to operate passenger trains to an even smaller loading gauge and have, as a consequence, obtained rolling stock identical to that of the "deep tube" lines of London Underground; these are lines built using the tunneling shield method, that were, by necessity, smaller than those lines built using the cut-and-cover method. In 1892, a Parliamentary Committee headed by James Stansfeld recommended that such lines be in tunnels with a minimum diameter of 11 ft 6in. Two routes operated by British Rail required the use of such deep-tube rolling stock, the Waterloo & City Line in London, and the Island Line on the Isle of Wight.

It operates passenger trains on the West Midlands franchise between London and the English Midlands under two trading names: within the West Midlands region as West Midlands Railway (WMR) and outside the region as London Northwestern Railway (LNR).
