context_page_description: The British Rail Class 317 is an alternating current electric multiple unit constructed by British Rail Engineering Limited in two batches, 48 sets being produced in 1981–82 and 24 sets in 1985–87. They were the first of several classes of British Rail EMU to be based on the all-steel Mark 3 bodyshell, departing from the "PEP"-aluminium design which had spawned the earlier Class 313 to Class 315, Class 507 and Class 508. The Mark 3 bodyshell was also the basis of Class 318, Class 455, and the diesel Class 150.
context_section_description: In 2000, nine Class 317/1 units were selected to be refurbished for the dedicated Stansted Express service, from London Liverpool Street to Stansted Airport, replacing the previously dedicated Class 322 units. The work was again carried out by Railcare at Wolverton, and included the fitting of luggage racks and new window frames, identical to existing 317/2 units. The units also received a revised front end design, and a new metallic blue livery. The nine units were reclassified as Class 317/7, and were renumbered such that the last two digits of the set number remained unchanged. Again some Class 317/7 units have had their original Stone Faiveley AMBR pantograph replaced by the Brecknell Willis High Speed design.
  In 2006 twelve further Class 317 EMU trains were given a more basic refresh of new carpets, retrimmed seats in new moquette and new dado side panels; by Wabtec Doncaster and the bodysides were painted in a lighter shade of blue than the Class 317/7. These units were reclassified as Class 317/8.
  Both Classes 317/7 and 317/8 could occasionally be found working on West Anglia services and also it was not uncommon for Classes 317/5 and 317/6 units to work Stansted Express services alongside the dedicated Classes 317/7 and 317/8.
  Following the arrivals of the new Class 379 units on Stansted Express services, the Class 317/7s and 317/8s were originally used alongside other Class 317s as a common pool. This changed when Abellio took over the East Anglia franchise on 5 February 2012, as the Class 317/7s were deemed too expensive to lease and surplus to requirements, and so they entered storage.
