The British Rail Class 508 (4PER) electric multiple unit (EMU) passenger trains were built by British Rail Engineering Limited, at Holgate Road carriage works, York, in 1979 and 1980. They were a variant of British Rail's standard 1972 design for suburban EMUs, eventually encompassing 755 vehicles and five classes (313/314/315/507/508).[10] They mostly worked on the Merseyrail network from 1982 until withdrawal on 16 January 2024.[1]

Description
Summarize
Perspective
The class was developed for Merseyside, following extensive trials and testing of the 4Pep/2Pep stock that was built in the early 1970s. Testing of Class 313 took place on the Northern line on Merseyside, using 313013/063[11] which were loaned from the Great Northern Line of the Eastern Region to Hall Road TMD. Original plans were drawn up for 58 Class 508s to be constructed, although costing issues limited the eventual number to 43. Following planning and building, British Rail diverted the 508s to work alongside much older first-generation 4Sub EMUs in the London Waterloo area. The first unit was delivered to Strawberry Hill depot on 9 August 1979. Based at Wimbledon Traincare Depot, they soon became problematic due to their non-standard dimensions and brake problems caused by leaf fall.[7][12]
Once a new build of Class 455 EMUs was completed, the Class 508s were sent slowly to their originally intended home on the Merseyrail network. Driver training began at Kirkdale on 17 February 1982 and the first Class 508 began service on the Northern line the following month. The first Wirral line service commenced on 8 June 1984 and the Class 508s had completely displaced the Class 503 fleet by the end of March 1985. The fleet was then working in parallel with the already well-established fleet of Class 507 EMUs across the River Mersey, which had been working on Merseyside since 1978.[7]

Perspective
Silverlink/London Overground
Silverlink leased three 508/0s in 2003 for operation on the Watford DC Line to assist its fleet of Class 313 EMUs. They were modified to make them inter-operable with 313s and were reclassified as Class 508/3. These were withdrawn following the delivery of Class 378 Capitalstar units, and the 508/3s were scrapped in 2013.[8]
Merseyrail
In the late 1980s under British Rail, the entire class of 43 units operated on the Merseyrail network,[13] By 2010, the number operated by Merseyrail had been reduced to 27 units.[14] and were primarily maintained at Birkenhead North TMD, with minor maintenance being undertaken at Kirkdale TMD.
A farewell tour for the Class 508 operated using units 508139 and 508141 took place on 29 October 2023,[15] and the class was withdrawn from service on 16 January 2024.[1]
Southeastern
Connex South Eastern leased twelve Class 508s freed up by capacity reductions on Merseyrail services in 1996, for operation on specific Kent services that would replace slam-door 4CEP units.[16] They were refurbished at Eastleigh Works, including the installation of 2+2 seating and wheel-in cycle racks in the centre cars, and reclassified as the Class 508/2 (508201-212).[17] Their main duties included London Bridge to Tunbridge Wells, Paddock Wood to Strood, Maidstone West to Three Bridges and Sittingbourne to Sheerness-on-Sea, as well as Grove Park to Bromley North for a short period. Units were based at Gillingham Depot.[citation needed]
Due to their comfort and ride quality, alongside the lack of toilets and first class facilities, which were felt as a downgrade from the slam-door units they replaced, the Class 508s were unpopular with passengers. In 2005, one unit was refurbished by interim operator South Eastern Trains to improve external appearances, with a black, white and yellow livery.[citation needed]

Replacement
Summarize
Perspective
Southeastern
In September 2006 new operator Southeastern announced that a cascade of rolling stock would see Class 466 units replace the 508s on the Sheerness and Medway Valley lines in the December 2006 timetable.[18] Following this timetable change, the fleet's diagrams were reduced to six serviceable units, resulting in five sets being placed in "warm store" at Chart Leacon TMD, and one unit was cannibalised. With the transfer of the Tonbridge to London via Redhill services to Southern, Southeastern placed its remaining Class 508 units in store in December 2008.[19]
Network Rail's Route Utilisation Strategy for Merseyside has called for an expansion to Merseyrail's current fleet to allow for both additional services and lengthening of trains to six cars. In December 2009 it was reported by various sources that the former Southeastern and London Overground units would be transferred to Merseyrail.[20][21]
Merseyrail
In May 2012, Merseytravel announced that it was beginning a project for replacement of the Class 508 and 507.[22][23] The lease on the Class 507s and 508s had been extended to 2018. As part of the agreement with Angel Trains, the fleet received a refresh package including external re-livery, internal enhancements and engineering work.[24]
In January 2016, Merseytravel announced the short list of companies bidding to build new trains which will replace the Class 507 and Class 508s on the Merseyrail network.[22] In December 2016, Merseytravel announced that Stadler had won the £460 million contract and that the new Class 777 trains were to be delivered from summer 2019 with all the old trains replaced by 2021.[25] The first unit entered service late in January 2023.[26]
The last Class 508 unit was sent for scrap in February 2024.[27]
Accidents and incidents
- On 21 April 1982, unit 508031 was running the 06:34 service from London Waterloo crashed at Shepperton, demolishing barriers and a wall. The train also slid into some new pedestrian crossing lights, rendering them unusable. The crash was initially believed to be the result of braking tests the previous night, which involved applying grease to the tracks, and that the grease may not have been sufficiently cleaned off. It was later found that the train's brakes were faulty.[28]
- On 26 October 2005, unit 508124, forming 2W43 17:06 West Kirby return via Liverpool Lime Street, derailed 200 m (660 ft) short of Liverpool Central, caused by track gauge widening due to poor track condition. There were no serious injuries. The RAIB report cited incompatibility between Class 508 (and 507) EMUs and the Liverpool Loop track as a causal factor, along with maintenance and other track design concerns.[29]
- On 6 March 2007, a Class 508/3 unit, forming the 05:00 Tonbridge to Gatwick Airport, derailed near Crowhurst, Surrey, after hitting a fallen tree on the line. None of the eight people on board were hurt.[30]
