==== Class 319 ====
[[File:319004 Thameslink train at St Albans.jpg|thumb|86 Class 319s worked the Thameslink route from 1987 to 2017]]
Rolling stock used on Thameslink included the 86 [[British Rail Class 319|Class 319]] trains built between 1987–1988 and 1990. These are [[Railway electrification in Great Britain|electrically powered]] dual-voltage four-car units rated to carry 289, 308 or 319 passengers. Four Class 319 trains had been transferred from [[Southern (train operating company)|Southern]] in December 2008 and the last four followed in March 2009, from which point they were all on Thameslink. The last was withdrawn in August 2017.<ref>{{cite news |url=http://www.railtechnologymagazine.com/rail-news/thameslink-replaces-last-of-30-year-old-class-319-fleet |title=Thameslink replaces last of 30 year old Class 319 fleet |archive-url=https://web.archive.org/web/20170915204248/http://www.railtechnologymagazine.com/rail-news/thameslink-replaces-last-of-30-year-old-class-319-fleet |archive-date=15 September 2017 |publisher=Rail Technology Magazine |date=1 September 2017 |url-status=dead}}</ref>

==== Class 377 ====
First Capital Connect acquired 23 four-coach [[British Rail Class 377|Class 377]] sets during 2009 on sublease from [[Southern (train operating company)|Southern]], for the Thameslink route for additional capacity and to allow some of the Class 319 trains to be released for the [[Catford Loop Line|Catford Loop]] service to Sevenoaks, now jointly operated with [[Southeastern (train operating company)|Southeastern]] under [[Thameslink Programme#Summary of project phases|Key Output 0]] of the Thameslink Programme.<ref>{{cite web |url= http://www.thameslinkprogramme.co.uk/index.php/faqs/faqs_categories/public_index#question_29 |title= Do we really have to wait until 2012 and 2015 for some relief to the overcrowding? |date= 20 October 2008 |publisher= [[First Capital Connect]] |access-date= 28 October 2008 |url-status= dead |archive-url= https://web.archive.org/web/20081109090627/http://thameslinkprogramme.co.uk/faqs/faqs_categories/public_index#question_29 |archive-date= 9 November 2008 |df= dmy-all}}</ref>

==== Class 317 ====
[[British Rail Class 317|Class 317]] units built in the early 1980s were still in use when services into Moorgate ceased in March 2009: the last timetabled service ran from Farringdon to Bedford on 9 October 2009.

==== Class 387 ====
Due to delays in the new [[British Rail Class 700|Class 700]] fleet, the DfT and Southern ordered 116 electric dual-voltage {{convert|110|mph|kph|adj=on}} carriages (29 trains) with the option for another 140 carriages (35 trains).<ref name="DfT">{{cite web |publisher =Department for Transport |url= https://www.gov.uk/government/news/department-for-transports-boost-to-train-builders |title= Boost to train builders |date=21 December 2012 |access-date=23 May 2014}}</ref><ref name="Southern">{{cite press release |url=http://www.southernrailway.com/southern/news/procurement-of-new-rolling-stock/ |title=Procurement of New Rolling Stock |archive-url=https://web.archive.org/web/20130329061413/http://www.southernrailway.com/southern/news/procurement-of-new-rolling-stock/ |archive-date=29 March 2013 |url-status=dead}}</ref> The tender for the new {{BRC|387}} trains was won by Bombardier and the first set entered service in December 2014, with all in service by May 2015.
