Class 150
The Class 150 was the first of BR's 'Sprinter' DMUs, 1980s replacements for life-expired first generation units. Around 130 are in use, mostly 2-cars with a few 3-car sets, operating local services for Northern, Great Western, West Midlands and Transport for Wales. Withdrawals of TfW units have recently begun.
Class 444, 450
These classes are similar EMUs from the Siemens Desiro Mainline range. The 127 Class 450 4-car units for outer suburban services were introduced in 2003 and the 45 Class 444 5-car units for long distance services the following year. All are 750V DC 3rd rail units and work for South Western Railway.
Class 158, 159
The 2-car Class 158 DMUs were introduced in 1989 to replace loco hauled trains on major regional routes. Some now run as 3-car sets. The 159s are very similar 3-car units originally owned by Network South East rather than Regional Railways. Both classes are still hard at work across the network.
Class 220, 221, 222
Classes 220, 221 and 222 are similar high speed DEMUs built by Bombardier between 2000 and 2005. In total 105 units were built in various configurations for long-distance services. Cross Country, East Midlands and Grand Central all currently operate these trains but Avanti have recently replaced theirs.
Class 165, 166
The Class 165 and 166 DMUs were introduced in 1990 for local and regional services on the Thames Valley and Chiltern routes. Many have now moved to other GWR services further west. As DMUs go they're among the most attractive in use today with rounded fronts unspoilt by corridor connections.
Class 800 - 810
Classes 800 to 810 are new bi-mode high-speed units built by Hitachi for various operators including LNER, GWR and TPE and introduced in 2017. Some units have plenty of diesel power and can operate normally away from the wires, others just enough to keep them moving if the power fails.
Class 390
Virgin Trains introduced the 53 Alstom built Class 390 Pendolinos to the West Coast Main Line in 2002 and these 9 and 11 car 25kV EMUs soon dominated Inter City services on the route. At the end of 2019, the class 390s passed to Avanti West Coast, the new franchisee, and remain on WCML services.
Class 375, 377, 379, 387
Classes 375, 377, 379 and 387 are all Bombardier Electrostar EMUs, intended for outer suburban and medium distance services. Some are 25kV AC only, others 750V DC only and yet more are dual system. Almost 500 units are in service with various operators, mainly in the south-east of England.
Class 458
The 30 Class 458 4 car 750V DC EMUs were the first new design for a privatised operator and have had an interesting life, being rebuilt twice in a career of less than 30 years. Most units are now running as 4-car 458/4s but a few 5-car 458/5s remain, all in service with SWR but they face an uncertain future.
Class 345
Class 345 EMUs are 9-car 25kV units from the Bombardier Aventra family introduced in 2017 for use on Crossrail services operated by TfL. Many units entered service as 7-car sets but all 70 were strengthened to 9-cars by the time the full Elizabeth Line service was introduced in May 2023.
Class 168 & 170-172
Classes 168, 170, 171 and 172 are all developments of the BR Class 165 and 166 DMUs and were built for privatised operators by Bombardier in Derby from the late 1990s. Many are used on longer distance services such as Marylebone - Birmingham, Nottingham - Cardiff or Glasgow - Inverness.
Class 455, 456
137 Class 455 4-car 750V DC EMUs were built in the mid-1980s to replace older slam-door stock. The 24 Class 456 2-car units followed in 1991. The 456s and many of the 455s have recently been withdrawn. The remaining 455s are in service with South Western but are overdue for replacement.
Class 701
The Class 701 750V DC EMUs are from the Bombardier Aventra range and intended for use on South Western's inner and outer suburban routes. An order for 60 10-car and 30 5-car sets was placed in 2017 and, although testing has taken place, the vast majority of units are yet to enter service.
Class 491 4TC
The Class 491, later 438, also known as the 4TC, was developed for the Bournemouth electrification in 1967 and was an unpowered 4-car unit that was pulled or pushed by locos or EMUs. They saw use on other routes including the Waterloo - Salisbury line. All were withdrawn by 1990.
Class 397
A small class of 12 EMUs operated by Trans-Pennine on long distance services linking Glasgow and Edinburgh with Liverpool and Manchester via the WCML. The 5-car units were built by CAF and introduced by TPE in late 2019. Despite running at up to 125mph they have no yellow warning panels.
Class 319, 769
86 Class 319 4-car 25kV AC / 750V DC EMUs were built between 1987 and 1990 for Thameslink services. Since their replacement in 2015 some have been used on other routes or converted to Class 768 parcel units or Class 769 diesel/electric hybrids. The remaining 319s and 769s are due for withdrawal.
Class 185
The 51 Siemens built Class 185 3-car DMUs all work for Trans Pennine Express on various medium to long distance routes across northern England, occasionally reaching Glasgow or Edinburgh as well. They were built in 2006 and are the UK's only examples of Siemens Desiro DMUs.
Class 325
The 16 Class 325 4-car EMUs were introduced in 1995 for postal services on 25kV AC and 750V DC electrified routes. They were owned by Royal Mail and operated by DB Cargo between Willesden, Warrington and Shieldmuir. Mail trains ceased in 2024 and several 325s have since been scrapped.
Class 350
The 76 Class 350s are 4-car 25kV EMUs from the Siemens Desiro Mainline range, built for outer suburban and long distance services from 2005. They are very similar to the Class 450 750V DC units. All 350s are now with London Northwestern, part of WMT, but 10 were used by Trans Pennine until 2020.
Class 707
The 30 class 707 5-car 750V DC inner suburban EMUs are from Siemens' Desiro City range and capable of modification to use 25kV AC. They entered service with South West Trains in 2017, principally on Windsor Lines services. The whole class has recently been transferred to South Eastern.
Class 180
The 14 5-car Class 180 high speed DMUs were plagued with reliability issues in their earlier years. Originally all were with First Great Western but some later went to Hull Trains. The only current operator is Grand Central but they also worked for East Midlands until recently.
Class 156
Metro-Cammell built 114 2-car Class 156 DMUs for BR in the late 1980s. They were originally intended for medium-distance limited-stop services but soon gravitated to less important duties. All 114 units are still in service, currently working for the ScotRail and Northern franchises.
Class 423 4-VEP
The 4-VEP, later Class 423 750V DC EMU was a mainstay of the Southern Region's outer suburban services from the late 1960s until the early 2000s. They were 90mph 4-car units with an external door to every seating bay, a factor that led to their demise due to safety concerns over slam door stock.
Class 442
The Class 442 750V DC EMUs were 5-car sets built for Waterloo - Weymouth services when electrification was extended to Weymouth in 1988. They worked for Gatwick Express from 2007 to 2016. A return to SWR for Portsmouth services was cancelled in 2021 and most vehicles have now been scrapped.
Class 421 4-CIG
The 4-CIG, later Class 421, was the standard Southern Region long distance 750V DC 4-car EMU from the late '60s, used across the region and particularly on the Central division. Safety concerns over slam-door stock led to their replacement by new sliding door stock during the first few years of this century.
Class 320, 321, 322
Classes 320, 321 and 322 are closely related 25kV AC EMUs built by BREL's York Works around 1990. The 3-car Class 320s work for ScotRail around Glasgow. A few Class 321 4-car units have been converted for light freight use but the vast majority of 321s and all the 322s have now been withdrawn.
