 which were introduced in 1984.

They were initially built for use on rural branch lines. However, as of September 2011 they are mainly used on busy commuter routes in the major cities in the north of England, with some also in use on local services around Cardiff and on Devon branch lines.

Under the Disability Discrimination Act drawn up in the mid 1990s, all public transport will need to be accessible by 2019. Pacers are unable to meet this requirement so will have to be withdrawn by the end of 2019.

Description

The train body is based on that of the original designs of Thomas Kenneth Cullum and the Leyland National
Leyland National

 of any number between 102 and 121 passengers per twin-car set. In theory there should be 106 or 121 seats per unit. However, many units have had seats removed to provide additional space for wheelchair access. The same engines and mechanical transmissions were used as on Class 141

, as well as the double-folding external doors.

Excessive flange squeal on tight curves has been a problem on many routes operated by 142s, 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 ) Nodding Donkeys. 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 to be unsuitable for the sharply curved branch lines there.

Upgrades and refurbishments

The class was upgraded in the early 1990s. This was after a number of problems were experienced with the mechanical transmission and engines (including complete seizures), and now all units carry a more powerful 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 45 mi/h. This has proven very successful, although incidents have occurred. In 2002 a North Western Trains unit derailed on the Carlisle to Whitehaven line when its engine fell off the chassis, and then a similar incident occurred when a Northern Rail

 unit derailed while on route from Blackpool to Liverpool in June 2009.

Detail modification is the replacing of the unreliable double folding doors with standard rigid folding examples used on Class 143 and 144 Pacers. The trains have also had new fire extinguisher equipment fitted, and more importantly, the replacement of the cable worked brakes by direct acting brakes.

 operated Pacers have been refurbished. This included an external relivery into the Valley Lines colours of red, white lime green and green. The doors were painted in lime green due to requirements by the 1998 Disability Discrimination Act.

The interior refurbishment included the following:
  • Installation of non slip vinyl flooring
  • Replacement of the existing 2+3 bench style bus seats with Chapman bespoke high backed seats to the 2+2 layout
  • Repainted dado side panels and wall ends
  • Installation of DPTAC 'easy to see, easy to press' yellow tactile LED Passenger Door Control buttons on a raised rubber surface surround

British Rail Provincial/Regional Railways

From new, some units were painted according to the region they operated in. For example, the first 14 Greater Manchester PTE-sponsored units (142001-014) received GMPTE Orange, then the next 13 WestCountry-based units (142015-027) were painted in a GWR-inspired chocolate and cream livery and marketed as 'Skippers'.. The remaining 69 units (142028-096), initially working across Lancashire / Greater Manchester, Merseyside and Yorkshire, received Provincial railbus two-tone blue livery.

Unit 142050 was the first Pacer to be fitted with Voith hydraulic transmission - initially on an experimental basis - to see if this configuration would be more reliable than the SCG mechanical gearboxes had been. In early Summer 1988, it was sent to Heaton depot (Newcastle) to work alongside the similarly troubled Class 143s, on what were considered arduous routes. The trial was considered enough of a success for all Pacers to be so converted in due course.

Owing to problems with excessive wheel wear on the sharp curves of the Cornish branches, the units from the West Country (142015-027) were moved north from late Summer 1988 - seven to Heaton depot (Newcastle) and six to Newton Heath depot (Manchester), to help alleviate DMU shortages in those regions. By the mid-1990s, the six former West Country units which had initially gone to Newton Heath were also transferred to Heaton, most / all still wearing their original chocolate and cream livery.

In 1989, Heaton depot implemented a planned Pacer renumbering scheme - which was to cover all Classes 142-144 - in which Class 142s would be renumbered 1422XX (SCG mechanical gearboxes) and 1425XX (Voith hydraulic transmission), thus, their units carried numbers 142516, 142518, 142519, 142520, 142521, 142522 and 142525, and all of their Class 143s were renumbered. However, the other two depots with Pacers, Newton Heath and Neville Hill (Leeds), never implemented this scheme. 142050 was not renumbered 142550, even though it remained allocated to Heaton throughout this time, probably because it was (still) considered to be 'on loan' from one of the other depots for the purpose of the trial. Subsequently, most of the Heaton units received a modified version of Tyne & Wear PTE yellow+white livery from 1992 (after the class 143s originally carrying this livery had transferred to Cardiff), and the opportunity was taken to renumber all back to 1420XX, in line with the rest of the class at the other depots.

Towards the end of the British Rail period, apart from T&WPTE livery mentioned above, other units began to be out-shopped in a revised GMPTE scheme, MerseyRail yellow+white, or standard Regional Railways livery.

 franchise, which inherited the combined fleet of 68 Class 142s.

Of the 68 Class 142s, most have been repainted in Northern Rail's dark blue and purple livery, with a small number retaining the Arriva Trains Northern livery. 142009 is named "Newton Heath 125 1876-2001".

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) some have been replaced by Sprinter trains and there are plans to replace more 142s.

Five 142s in service with First Great Western were returned to Northern Rail in December 2008, the rest returned to Northern by November 2011, much later than originally planned.

Despite being built for branch line stopping services, Class 142s are mainly used urban commuter services in and out of cities like Liverpool

 derailed while on route from Blackpool to Liverpool. All 40 passengers on board escaped serious injury, but one person was taken to hospital with minor injuries. An investigation is currently being carried out, but it has been suspected that a major problem with the engine occurred as passengers saw large parts of it on the track. Problems with engines on 142s have been experienced before.

The ensuing report recommended that they be withdrawn and replaced in the near future with heavier, more sturdy Sprinters. However, as there are no spare Sprinters available, only 142008 and 142059 have been withdrawn, both through accident damage. 142059 was withdrawn in 1990 after colliding with a buffer stop at Liverpool Lime Street. The train had run away down the hill from Edge Hill whilst returning with brake problems. The train was running without passengers at the time and the driver and guard both survived the accident without serious lasting injury. The platforms were evacuated in time before the train struck the buffers.
