They were the fourth variant of BR's standard 1972 design for suburban EMUs, eventually encompassing 755 vehicles and five classes (313/314/315/507/508). They have mostly worked on the Merseyrail network since 1983, and continue to do so, now refurbished by Alstom's Eastleigh Works. The Class 508 unit is now {{age|1979|01|01}} years old, making them among the oldest units still in service on the UK mainland rail network, after the Class 313 and Class 507. DescriptionThe class was developed for Merseyside following extensive trials and testing of the 4Pep/2Pep stock built in the early 1970s. Testing of Class 313 took place on the Northern Line on Merseyside, using 313013/063[7] which were loaned from the Great Northern Line of the Eastern Region[8] to Hall Road depot. Original plans were drawn up for 58 Class 508s to be constructed,[8] although costing issues limited the eventual number to 43. However, following planning and building, British Rail decided to divert 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.[8] Based at Wimbledon Park depot, they soon became problematic due to their non-standard dimensions and brake problems caused by leaf fall.[8][9] Once a new build of Class 455 EMUs were complete, the Class 508s were slowly sent to their originally intended home on the Merseyrail network. Driver training began at Kirkdale on 17 February 1982,[10] and the first Class 508 began service on the Northern Line the following month.[10] The first Wirral Line service commenced on 8 June 1984,[10] and the Class 508s had completely displaced the Class 503 fleet by the end of March 1985.[10] 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. Delivered to the Southern Region as four-car sets numbered 508 001–043, all of the sets were reduced to three cars for Merseyside operation by the removal of one trailer and renumbered as 508/1. The individual passenger door controls were plated over before they were sent north. The spare trailer car from each set was incorporated into class 455/7 EMUs. Carriage numbering is as follows:
Current operationsMerseyrailMerseyrail operates 27 508s, which are used interchangeably between the Northern Line and the Wirral Line. They commonly work the following services:
Merseyrail's fleet of Class 508 units are primarily maintained at Birkenhead North TMD, with minor maintenance being undertaken at Kirkdale TMD. The units, when out of service, have stabling points at various sidings around the Merseyrail network. These can be found at the station termini and the depots, as well as at Rock Ferry station and Birkenhead North station. Past operationsSoutheasternConnex South Eastern leased twelve Class 508s freed up by capacity reductions on Merseyrail services in 1996 (508101/105/106/107/109/113/116/119/121/129/132/133), for operation on specific Kent services. Their main duties included {{rws|London Bridge}} to {{rws|Tunbridge Wells}}, {{rws|Paddock Wood}} to {{rws|Strood}}, {{rws|Maidstone West}} to {{rws|Three Bridges}} and {{rws|Sittingbourne}} to {{rws|Sheerness-on-Sea}}, as well as {{rws|Grove Park}} to {{rws|Bromley North}} for a short period. Units were based at Gillingham Depot.[11]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.[12] Following this timetable change the fleet was reduced to six serviceable units. There were five sets in 'warm store' at Ashford Chart Leacon, and one unit, 508212, was cannibalised to keep the surviving service units in operation, including the swap of its TSO coach with one from a unit that ran into a tree on the Redhill to Tonbridge Line. With the transfer of the Tonbridge to London via Redhill services to Southern, Southeastern placed its remaining 508s in store in December 2008.{{citation needed|date=January 2017}} SilverlinkSilverlink leased three 508s from Angel Trains in 2003 for operation on the Watford DC Line to assist its fleet of {{brc|313}} EMUs. These were withdrawn following the delivery of {{brc|378}} Capitalstar units. These three Class 508/3 units were modified by Alstom Eastleigh to designs provided by Interfleet Technology to make them inter-operable with Class 313 units.

Incidents
ReplacementOn 14 May 2012, Merseytravel announced that it was beginning a project for replacement of the 508s and 507s.[34][35] The lease on the Class 507s and 508s has been extended to 2018. As part of the agreement with Angel Trains, the fleet will receive a refresh package including external re-livery, internal enhancements and engineering work.[36] On 11 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.[34] In December 2016, Merseytravel announced that Stadler had won the £460 million contract and that the new {{brc|777}} trains would be delivered from summer 2019 with all the old trains replaced by 2021.[37] References1. ^1 2 3 4 5 6 7 8 9 10 {{harvnb|Fox|1994|p=86}} 2. ^1 2 3 4 5 6 7 8 9 10 11 12 {{cite book| last = | first = | title = Vehicle Diagram Book No. 210 for Electric Multiple Units (Including A.P.T.) | publisher = British Railways Board | location = Derby | date = 1981 | page = EA208, EH218, EI203 | work=Barrowmore MRG |url=http://www.barrowmoremrg.co.uk/BRBDocuments/Diagram_Book_210_for_Issue.pdf |isbn = }} 3. ^1 2 3 4 {{cite web|url=http://www.therailwaycentre.com/Recognition%20Tech%20Data%20EMU/EMU_508.html|title=Class 508|work=The Railway Centre|accessdate=31 January 2016|archiveurl=https://web.archive.org/web/20080724190140/http://www.therailwaycentre.com/Recognition%20Tech%20Data%20EMU/EMU_508.html|archivedate=24 July 2008}} 4. ^{{harvnb|Maund|2001|p=78}} 5. ^{{harvnb|Marsden|1982|pp=4, 6}} 6. ^{{cite web|url=http://www.abrail.co.uk/MAG%2036.htm|title=Trans Pennine: The Magazine of the Pennine Railway Society|work=AbRail|accessdate=3 August 2016}} 7. ^{{harvnb|Cadwallader|Jenkins|2010|p=42}} 8. ^1 2 3 {{harvnb|Maund|2001|p=82}} 9. ^{{cite magazine|title=Readers' round-up|magazine=Rail Enthusiast|publisher=EMAP National Publications|date=February–March 1982|p=51|issn=0262-561X|oclc=49957965}} 10. ^1 2 3 {{harvnb|Maund|2001|p=85}} 11. ^{{cite web|url=http://www.kentrail.org.uk/class_508.htm|title=Class 508|work=Kent Rail|accessdate=2 December 2015}} 12. ^{{cite web|url=http://www.southeasternrailway.co.uk/news.php?id=38&u=news.php&lm=remindpass|title=New Southeastern timetable begins in December|date=5 September 2006|accessdate=4 June 2014|archiveurl=https://web.archive.org/web/20061006132551/http://www.southeasternrailway.co.uk/news.php?id=38&u=news.php&lm=remindpass|archivedate=6 October 2006}} 13. ^{{cite web|url=https://www.flickr.com/photos/95289374@N04/30040483283/|title=Class 508 (508201) at Seacombe|author=|date=|website=flickr.com|accessdate=10 April 2018}} 14. ^{{cite web|url=https://www.flickr.com/photos/130120190@N03/30719753495|title=508209 -
