The British Rail Class 150 Sprinter is a class of diesel multiple-unit trains built by BREL York from 1984 to 1987. A total of 137 units were produced in three main subclasses, replacing many of the earlier, first-generation "Heritage" DMUs.

At the beginning of the 1980s, British Rail (BR) had a large fleet of ageing "Heritage" DMUs built to various design types. While some of the more reliable types were retained and refurbished, BR replaced many of the non-standard or unreliable models with new second-generation units built to modern standards. Two different types were developed: low-cost "Pacers", built using bus parts for use on short-distance services, and "Sprinters", based on BR's Mark 3 body design for longer-distance services.
In 1984, BREL built two prototype, three-car, Class 150/0 units, numbered 150001 and 150002. 150001 was fitted with Cummins engines and Voith hydraulic transmission, and 150002 was fitted with Perkins (Rolls-Royce) engines and a fully automatic gearbox developed by the Self-Changing Gears company.
The design specifications of the prototypes were similar to the later production units, but they were to remain as the only Class 150s to be built as three-car units. Additional three-car units were created later by re-marshalling a 150/2 car in the middle of a 150/1 set, but only the prototypes had purpose-built centre cars without driving cabs. Both cab doors are air-operated, unlike the Class 150/1 production model but seen later on in the 150/2 variant.
150002 proved to be the worse of the two for reliability and was consequently chosen for use as the testbed for the Class 158, being re-geared to a maximum speed of 90 mph (140 km/h) and fitted with Cummins engines and Voith transmission, and with a Class 158 interior. One car was fitted with the Class 151 Twin Disc 'hot-shift' transmission, which it used successfully once the control software was sorted out. To distinguish this unit, it was reclassified as the Class 154. It has since been returned to the standard configuration and reverted to its original number. Both prototypes were still in service with London Midland until 2011. 150001 entered service with First Great Western in January 2012, with 150002 to follow after refurbishment and re-livery. They are now used primarily on the Reading-Basingstoke line, with both 150001 & 150002 in the new Great Western Railway green livery.
At the same time that BREL built the 150/0s, Metro-Cammell built two prototype Class 151 units at its Washwood Heath plant.[a] The two types of unit were exhaustively tested, with a view to placing further orders for the more successful. In the event, the two Class 150 units proved to be more reliable, and as a result an order for 50, two-car units was placed with BREL.

This second batch of fifty units were classified as Class 150/1 and numbered in the range 150101-150. Like the prototype units, they did not have front-end gangway connections which allowed passengers to move between two units that were working in multiple. Originally based at Derby Etches Park depot, these units were introduced in 1986, mainly concentrated around Birmingham and Manchester, and in later years restricted mainly to commuter services.
The final batch of 85 two-car units were built with front-end gangway connections. These units were classified as Class 150/2 and numbered in the range 150201-285. They were used on longer-distance services. The end gangways make them very similar in appearance to the Class 317/2 and Class 455/7 and 455/9 EMUs, also based on the Mark 3 bodyshell.
Some of the Class 150/2 units were later disbanded, and the vehicles were used to make some of the Birmingham and Manchester-based Class 150/1 units into three-car sets. The units in Manchester were later returned to their original configuration, but the Birmingham-based units were renumbered into the 1500xx range by subtracting 100 from the previous number (e.g. 150103 became 150003). This also gave the operational advantage of there being an extra set of passenger door controls within the train for use by the conductor, making it easier to collect revenue without having to run the full length of the unit between stations.
The 450 Class is built using the Class 150 bodyshell and is operated by Northern Ireland Railways. It came to the end of its design life in 2014 so most of them were scrapped, though two remained.
One further unit was built specifically for testing duties. Originally numbered in the Class 180 series, the unit is now in the departmental Class 950 series, numbered 950001, and carries the yellow Network Rail livery.
The Class 150 units have BSI couplers which enable them to work in multiple with Class 142, Class 143, Class 144, Class 153, Class 155, Class 156, Class 158, and Class 170 units, as well as with units of the same class. However, they cannot work in multiple with Class 165 or Class 166 units due to incompatible wiring arrangements.
Unique passenger door controls
When introduced, the Class 150s had unique interior door open/close buttons. In the north of England they were square and blue. In the south of Scotland they were yellow in colour, and lit up turquoise when enabled. The button lit up bright yellow in the south of England.
The illumination feature was intended to aid visually impaired people, although they did not meet the subsequent standards set out by disability regulations that were later introduced, because they had no raised braille and were too small for some disabled people to locate.
As a result of this, the blue buttons are being replaced by the standard EAO series 56 'easy to see, easy to press' raised circular door button, with braille writing for the visually impaired, over a yellow surround to comply with the Rail Vehicle Accessibility Regulations.
After privatisation, North Western Trains (which was taken over by First North Western shortly afterwards) and Arriva Trains Northern operated Class 150/1 and 150/2s on their routes. The North Western Trains units underwent refurbishment by Hunslet-Barclay in Kilmarnock. When Northern Rail took over, both the former NWT and ATN Class 150s were transferred to Newton Heath depot, Manchester, with the former North Western Trains Class 158s taking the 150s' places at Northern's Neville Hill depot (Leeds). All Northern 150s contain high-density 2+3 seating. During late 2011, Northern Rail received various ex London Midland 150/1s and 150/2s when the brand-new Class 172 units entered service in the Midlands. This enabled Northern Rail to increase its most overcrowded services.
The new Northern franchise are receiving the Angel Trains 150/0s and 150/1s currently leased by GWR. These started transferring North in September 2017 and will finish in April 2019. Northern has announced that 24 of their class 150 units will be reformed into three-car units by March 2019. The three-car sets will be used on routes including the Penistone Line and Leeds to Goole.

After British Rail was privatised, the fleet passed to Porterbrook who leased the trains to Wales & West, which was later split up into Wessex Trains and Wales & Borders (later Arriva Trains Wales) in 2001.
The two prototype three-car Class 150/0 units transferred from London Midland have replaced the Class 165 and 166 Turbo units currently used by Great Western Railway on the Reading to Basingstoke Line, which allowed the Turbo units to reinforce Thames Valley services. 150001 entered service in January 2012. Table 122 of the Winter 2012/2013 National Rail Timetable shows all FGW services on this route to be standard-class only.
Following privatisation, Wales & Borders continued to use the fleet of Class 150 units on branch-line services as well as on the commuter services around Cardiff known as the Valley Lines and the Vale of Glamorgan Line. The units transferred to Arriva Trains Wales in December 2003, with more later acquired for the reopened Ebbw Vale line. All of the ATW units were transferred to Transport for Wales on 14 October 2018.
Upon the privatisation of British Rail, the bus company National Express ran ScotRail, and its successor First ScotRail operated 18 Class 150s out of Edinburgh Waverley on Fife Circle services. Other workings included Dundee and Carnoustie, as well as operating alongside other DMUs such as Class 158s on the Crossrail services between Newcraighall through Edinburgh to Bathgate, Stirling, Dunblane and occasionally Perth. In May 2005, all 18 units were transferred to Arriva Trains Wales.
Anglia Railways was created upon privatisation of British Rail, and it initially inherited a small fleet of nine Class 150/2 units, later supplemented with a tenth. The units were based at Norwich Crown Point depot, and put to use on rural services in Suffolk and Norfolk. Lines using the units included the Bittern Line, the East Suffolk Line, and the Wherry Lines, as well as services from Ipswich to Cambridge. One unit each weekday was sub-leased to First Great Eastern for use on the Sudbury Branch Line.
Anglia Railways named almost all of its fleet after famous local figures.
150245 was the only unit not to be named. On 1 April 2004, Anglia Railways became part of the new 'One' franchise. The Class 150 units were transferred to Arriva Trains Wales (no. 150245) and Central Trains (all other units), having been replaced by Class 156 units from Central Trains.
National Express operated the North London Railways franchise from 1997 under the Silverlink brand. They had eight Class 150s; seven were cascaded from Central Trains following delivery of new Turbostar units in 2000, to replace the ageing fleet of Class 117 and Class 121 units. The eighth unit, no. 150121, was transferred to Silverlink in late 2005.
London Overground, which took over the North London network in 2007, inherited the eight Class 150/1 units. Six were employed on the Gospel Oak to Barking Line, while two were sent on long-term loan to First Great Western.
All units had names.[not in citation given] The majority of the names are references to the Marston Vale Line on which they operated during Silverlink's franchise: Leslie Crabbe was a long-standing railway employee, who worked on the route; Richard Crane is the chairman of the Bletchley to Bedford Rail Users Association who has campaigned for the line to be retained and expanded. Three of the names (marked with an asterisk) were inherited from the previously incumbent Class 121 units. All the units are now with First Great Western, and their names are no longer applied.
- 150120 - Gospel Oak - Barking 2000
- 150121 - Silver Star (renamed from Willesden Eight in 2007)
- 150123 - Richard Crane (renamed from Bletchley Seven[b] in May 2006)
- 150127 - Bletchley TMD*
- 150128 - Bedford - Bamberg 30 (renamed from Community Forest in September 2007)
- 150129 - Marston Vale*
- 150130 - Bedford - Bletchley 150
- 150131 - Leslie Crabbe*
By the end of October 2010, all London Overground's Class 150/1s had been replaced by a new fleet of eight two-car Class 172 units operating exclusively on the Gospel Oak to Barking Line. Their final use was on 28 October 2010, when unit 150128 formed the 19:02 Barking to Gospel Oak service. The six units were cascaded to First Great Western, together with nine of the London Midland fleet.
In 2010, London Midland ordered Class 172 replacements for its Class 150s. It initially hoped to retain some of the 150s as additional capacity, although they were also wanted by First Great Western and Northern Rail.London Midland was expected to lose all of its Class 150s, but a change in plan saw it retain three Class 150 vehicles as additional capacity, following a statement from the Department for Transport on 10 August 2011. However, London Midland lost two Class 153s to First Great Western as a result.
