They were a development of the earlier Class 141 which were introduced in 1984. DescriptionThe unit's body is based on that of the original Leyland National bus, and many fixtures and fittings of the bus can be found on the units.[10][11] Each unit has a seating capacity of any number between 102[6] and 121 passengers per two-car set. In theory there should be 106 or 121 seats per unit.[12] However, many units have had seats removed to provide additional space for wheelchair access.{{Citation needed|date=February 2009}} The same engines and mechanical transmissions were used as on Class 141, as also the same double-folding external doors. Each car has a fuel capacity of 125 gallons.[13] Rail squealExcessive flange squeal on tight curves has been a problem on many routes operated by 142s,[14] caused by the long wheelbase and lack of bogies. The rough ride which can result has led to the units being nicknamed (along with the related {{brc|143|cs}}) Nodding Donkey. The 142s were officially known as "Skippers" when they were briefly allocated to Cornwall in the mid-1980s. They were transferred elsewhere when they proved unsuitable for the sharply curved branch lines there. Upgrades and refurbishmentsThe class was upgraded in the early 1990s. All units carry a more powerful Cummins engine - 230 bhp per car, which equals 460 bhp (340 kW) per twin-car unit - and Voith two-stage hydraulic transmission, starting with a torque converter which switches to fluid coupling drive once the unit is up to {{convert|45|mi/h|km/h|0}}.[15] This has proven successful, although incidents have occurred, such as when a Northern Rail unit derailed en route from Blackpool to Liverpool in June 2009.[16] Operations{{Refimprove section|date=February 2009}}British Rail Provincial/Regional RailwaysFrom new, some units were painted according to the region they operated in. For example, the first 14 Greater Manchester Passenger Transport Executive sponsored units (142001-014) received GMPTE orange and brown, then the next 13 West Country based units (142015-027) were painted in a Great Western Railway inspired chocolate and cream livery and marketed as 'Skippers'.[17] Post privatisationNorthern England{{Expand section|date=March 2010}}Upon the privatisation of British Rail, the Class 142 Fleet was divided between North Western Trains in the North West and Northern Spirit in the North East. Northern Spirit started its operations in 1997 and continued until 2000. At this point, parent company MTL ran into difficulties and the company was sold to Arriva, who renamed it as Arriva Trains Northern. In 1998 ATN swapped seven Class 142s (142085-142091) for seven Class 150/2 units from Valley Lines.[18] In October–December 2002 these were swapped for unrefurbished units 142072-77 and 080-3, as 142086-091 had only recently been refurbished by Northern Spirit and Valley Lines wished to start their own refurbishment from scratch. In 2004 First North Western and Arriva Trains Northern were merged into the Northern rail franchise, which inherited a combined fleet of 79 Class 142s. All 79 Class 142s are now painted in Northern Rail livery. Due to rising passenger numbers in the north of England (by about 10% per annum and even by over 25% per annum at some stations where 142s are in operation),[11] some units have been replaced by Sprinter trains.[19] Five Class 142 Pacers, in service with First Great Western, were returned to Northern Rail in December 2008; the rest returned to Northern Rail by November 2011, much later than originally planned. Despite being built for branch-line stopping services, the Class 142s are mainly used on urban commuter services in and out of cities like Liverpool, Manchester, Sheffield, Leeds and Newcastle and can be seen on longer-distance services of up to three hours including the 1632 Middlesbrough-Carlisle service (nearly 110 miles); they had also been used on services between Blackpool North and Chester via Stockport, which ceased to operate in December 2008. All 79 passed with the Northern franchise to Arriva Rail North in April 2016. Class 142s have operated the following routes:
MerseysideA total of seventeen Class 142 units based at Newton Heath TMD (142041-049 and 142051-058) were refurbished for use on Merseyside Passenger Transport Executive's City Line on services around the Liverpool and Greater Manchester areas.[20] The refurbishment included dot-matrix route indicators, a new design of individual low-backed seating and the units were repainted into Merseyrail's livery. Upon privatisation these units passed to First North Western in March 1997. All of these sets are now with Northern and however remain in the livery of previous operator Northern Rail. Wales{{Expand section|date=March 2010}}Valley Lines acquired its Class 142s by swapping Class 150/2 units with Arriva Trains Northern. The Class 142s were initially painted in Valley Lines livery. Transport for Wales uses its Class 142 Pacer trains on the commuter lines around Cardiff, Barry and Penarth known as the Valley lines. All of its Class 142 Pacer fleet now bear the turquoise and cream house colours of Arriva Trains Wales. The Class 142s are frequently used for the Cardiff to Penarth service calling at Grangetown, Dingle Road and Penarth. The Class 142 units are also primarily used on South Wales Valley line routes and routes through the Vale of Glamorgan. On Valley and Vale of Glamorgan services, Class 142s are often coupled together with Class 143 or Class 150 units to cope with demand on the busy Valley Lines network. The Class 142s have received minor refurbishments with retrimmed seats in new moquette, plus the installation of ceiling-mounted CCTV cameras. South West EnglandTwelve Class 142 Pacers were received by First Great Western in 2007, and started operations in December 2007. These were loaned from Northern (where they had been stored), in part to cover for refurbishment of FGW's Sprinter fleets but also to allow the Class 158s to be reformed as three-coach sets. The 142s were based at Exeter TMD, working alongside the similar {{brc|143|cs}} on services in Devon and Cornwall, including the Avocet Line, Riviera Line and Tarka Line. Five 142s were returned to Northern Rail in the autumn of 2008, following the completion of the refresh of Class 150 Sprinter units. The remaining seven units were returned to Northern Rail in November 2011 after being replaced by class 150 units cascaded from London Overground and London Midland. FutureAll 94 Class 142s will be withdrawn by December 2019, as they do not comply with the Persons of Reduced Mobility Technical Specification for Interoperability (PRM-TSI).[21] Bidders for the Northern franchise that commenced in April 2016 were required to order new DMUs and take on Sprinters and Turbostars (Classes 150, 156, 158 and 170) released by other franchises as replacement.[22] 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.[23] Northern withdrawals were scheduled to commence in November 2018 with the last to be removed from traffic in October 2019.[24] This has been slightly delayed until the first Class 195s enter service. New Wales & Borders franchise holder KeolisAmey Wales will replace all of its Class 142s by December 2019.[25] Upon withdrawal 142001 will be preserved by the National Railway Museum.[26] LiveriesFleet details
