The British Rail Class 144 Pacer diesel multiple units (DMUs) were built by BREL Derby from 1986 to 1987. A total of 23 units were built, replacing many of the earlier first-generation "Heritage" DMUs.
The Rail Vehicle Accessibility (Interoperable Rail System) Regulations 2008 require that all public passenger trains must be accessible by 1 January 2020. No Pacer trains currently meet this requirement. Porterbrook has proposed an extensive refurbishment of the Class 143 and 144 units in an attempt to meet this requirement although this would significantly reduce the number of seats. Bidders for the next Northern Rail franchise must not operate any Pacer trains after 31 December 2019. They are required to order at least 120 new self-powered vehicles and are permitted to take on Sprinter and Turbostar units released by other franchises. The Long Term Passenger Rolling Stock Strategy for the Rail Industry indicates up to 500 non-electric carriages will need to be built in the short term.
At the beginning of the 1980s British Rail (BR) had a large fleet of ageing "Heritage" DMUs, built to many different designs in the late 1950s and early 1960s. Some of the more reliable types were retained and refurbished. However, BR decided to replace many of the non-standard or unreliable types with new second generation units, built to modern standards. Two different types were pursued; low-cost "Pacers" built using bus parts and used on short-distance services; and "Sprinters" built for longer-distance services.
Twenty-three Class 144 units were built. The units have a maximum speed of 75 mph (121 km/h) and are externally similar to the earlier Class 143 Pacers (they have a Walter Alexander body like the Class 143), built in 1985–1986. The first thirteen of the class, No. 144001-013 are 2-car units. The remaining ten, No. 144014-023 are all 3-car units, although all were originally built as 2-car units, the centre vehicle being added later. These ten Pacers are the only Pacers to contain intermediate vehicles.
Units are formed of two driving motors, one of which contains a toilet. The 3-car units have an additional intermediate motor. All vehicles have standard-class seating only. The technical description of the formation is DMS+(MS)+DMSL. Individual vehicles are numbered as follows.
- 55801-55823 - DMS
- 55850-55859 - MS (units 144014-023 only)
- 55824-55846 - DMSL
The class were built specifically for local services sponsored by West Yorkshire PTE (since rebranded as Metro). As such, the fleet was painted in the crimson/cream West Yorkshire Metro livery, although three units (nos. 144011-013) were later repainted into Regional Railways livery. Units are used on services such as:
- Harrogate Line - York-Harrogate-Leeds
- The Wakefield part of the Huddersfield Line - Leeds-Huddersfield
- The Huddersfield branch of the Calder Vale line
- Hallam Line - Leeds-Barnsley-Sheffield
- Penistone Line - Huddersfield-Barnsley-Sheffield
- Pontefract Line - Wakefield-Pontefract
They can also be found operating the Leeds-Morecambe services, services between Scunthorpe and Adwick to Sheffield and Lincoln and more recently from 2008, between Manchester Victoria and Leeds (usually via Brighouse) amongst others. Prior to 1994, they were also used on Leeds/Bradford-Ilkley and Leeds/Bradford-Skipton services. These lines were electrified in 1994, and passenger services were operated by Class 308 electrical multiple units. Due to their similarities, services booked for a Class 144 can often be replaced by a Class 142, and vice versa.
Since privatisation, the fleet has been operated by several franchises. The first operator was Northern Spirit, which was later taken over by Arriva Trains Northern who refurbished the fleet between 2002 and 2004, with units emerging in a new silver and red Metro livery complete with refurbished interior. In December 2004, the fleet was transferred to the new Northern Rail franchise. Northern Rail has started to replace the silver and red Metro livery with Northern Purple and Blue. During 2009, 144001-013 were all repainted. As of April 2010, all Class 144s have been repainted.
Northern Rail have commenced a refurbishment programme to their fleet of Class 144 trains. 144006 is the first one to be so treated and this was also the first one to be refurbished in the joint Arriva Trains Northern/WYPTE Metro programme eight years ago in 2002.

The Class 144e (Evolution) is a proposed refurbished variant of the Class 144 which will bring it up to the requirements of the Disability Discrimination Act of 2005. The prototype Class 144e unit (144012) will feature a number upgrades such as the addition of new 2+2 style seating, a fully accessible toilet, two wheelchair spaces and spaces for bicycles and luggage. The demonstrator unit is expected re-enter traffic in April 2015.
