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.
The East Kent Railway (EKR) is a heritage railway in Kent, England. It is located at Shepherdswell station on the London and Chatham to Dover mainline. The line was constructed between 1911 and 1917 to serve the Kent Coalfields. See East Kent Light Railway for details of the original lines. The Kent Collieries were mostly a failure with only Tilmanstone on the line producing any viable commercial coal and commercial traffic over the line. The line is operated by heritage diesel locomotives. It is home to a collection of heritage diesel locomotives including a British Rail Class 08, DEMU and electric multiple units including an in service British Rail Class 404 built in the 1930s and a more modern British Rail Class 365, which is to be used as a restaurant and a major events venue.
The British Rail Class 207 (3D) diesel-electric multiple units were built by BR at Eastleigh in 1962. The fleet had a lifespan of 42 years. The Southern Region class 201 to 207 DEMUs are nicknamed 'Thumpers' due to the noise their engine units make.
The British Rail TC multiple units were unpowered fixed formations of 3 or 4 carriages with a driving position at each end of the set, converted by BR's Holgate Road carriage works from locomotive-hauled Mark 1 carriages in 1966–1967 and 1974. The units built on experience gained from the prototype 6TC unit. In time the 3 car units were reformed into four car units to match the rest of the fleet and later classified as Class 442. This was later changed to Class 491, under which they spent the majority of their working lives. Shortly before withdrawal they were reclassified Class 438 and the units were renumbered to 8001-8034.
The British Rail Class 204 designation has been used twice for two similar types of diesel-electric multiple units.
The Marshlink line is a railway line in South East England. It runs from Ashford, Kent via Romney Marsh, Rye and the Ore Tunnel to Hastings where it connects to the East Coastway line towards Eastbourne and Brighton.
The British Rail Class 171 Turbostar is a type of diesel multiple unit (DMU) passenger train built by Bombardier Transportation at Derby Litchurch Lane Works in England. It is identical to the Class 170, except for the replacement of the BSI coupler with a Dellner coupler. This provision was made to allow emergency joining with Class 377 DC third-rail electric units, which Southern runs extensively on most lines. The units work on the southern regions of the British railway system, operating services from London Bridge to Uckfield and from Eastbourne to Ashford International, these routes being unelectrified between Hurst Green Junction and Uckfield and between Ore and Ashford International, respectively.
The British Rail Class 201 six-car diesel-electric multiple units (DEMUs) were built in 1957–1958 at Eastleigh and underframes were built at Ashford.
The Southern Region was a region of British Railways from 1948 until 1992 when railways were re-privatised. The region ceased to be an operating unit in its own right in the 1980s. The region covered south London, southern England and the south coast, including the busy commuter belt areas of Kent, Sussex and Surrey. The region was largely based upon the former Southern Railway area.
The British Rail Class 501 electric multiple units were built in 1955/56 for use on the former LNWR/LMS suburban electric network of the London Midland Region. A total of 57 three-car units were built.
The British RailClass 414 were two-car electric multiple units that were built between 1956 and 1963. They were withdrawn in 1995.
The British Rail Class 203, initially classified 6B, was a type of diesel-electric train. Seven units, numbered 1031-1037, were constructed in 1958 for use on the Southern Region. They were similar to the earlier Class 202 units, differing only in the substitution of a trailer buffet car for one of the three trailer second opens.
Network SouthCentral (NSC) was a shadow franchise that existed from 4 February 1994 to 13 October 1996, when Connex South Central took over the running of the franchise. The franchise is now part of the Thameslink, Southern and Great Northern franchise operated by Govia Thameslink Railway under the Southern brand. As with all shadow franchises, Network SouthCentral was a wholly owned subsidiary of the British Railways Board.
The British Rail Class 206 or 3R was a type of Diesel-electric multiple unit (DEMU), introduced in 1964. They were not 'built' as such but rather re-formed from Class 201 and EPB vehicles for use on Reading-Redhill-Tonbridge services. Six three-car sets were created, numbered 1201-1206.
Pullman trains in Great Britain were mainline luxury railway services that operated with first-class coaches and a steward service, provided by the British Pullman Car Company (PCC) from 1874 until 1962, and then by British Railways from 1962 until 1972. Many named mainline service trains have subsequently used the word 'Pullman' in their titles, but most of these have been normal trains with increased first-class accommodation. Since 1982 however, some railtours have been operated by companies using Pullman coaches dating from the 1920s to 1950s to recreate the ambience of the heyday of Pullman travel.

Network SouthEast (NSE), the sector of British Rail which ran passenger services in London and southeast England between 1986 and 1994, operated a wide variety of rolling stock during its existence. The majority of the network was electrified, and further electrification schemes took place during the 1986–1994 period; and the 7,000 vehicles owned by NSE in 1986 consisted of a mixture of electric, diesel-electric and diesel multiple units, diesel locomotives and the coaches they hauled.
Class 201, Class 202 and Class 203 were the TOPS codes for a series of Diesel-electric multiple units built for the Southern Region of British Railways in 1957–86. They were classified by the Southern Region as 6S, 6L and 6B respectively, and known collectively as the Hastings Diesels or Hastings Units. They were built for service on the Hastings Line, which had a restricted loading gauge due to deficiencies in the construction of the tunnels when the line was built between 1845 and 1852. The Hastings Units served from 1957 to 1988, being withdrawn when the Hastings Line was electrified with single-track sections through some of the tunnels.
An electro-diesel multiple unit (EDMU) or bi-mode multiple unit (BMU) is a form of a multiple unit train that can be powered either by electric power picked up from the overhead lines or third rail or by using an onboard diesel engine, driving an electric generator, which produces alternating current (AC) or direct current (DC) electric power.
The Vivarail D-Train is a family of multiple units remanufactured by Vivarail for the British rail network. They are converted from London Underground D78 Stock, originally manufactured between 1978 and 1981 by Metro-Cammell. Two versions have been produced: the Class 230 diesel electric multiple unit and the Class 484 electric multiple unit.
