British Rail Class 314

The British Rail Class 314 is a retired class of alternating current electric multiple unit trains built by British Rail Engineering Limited at Holgate Road carriage works in 1979. The units were derived from British Rail's 1971 prototype suburban design, which as the BREL 1972 family eventually covered 755 vehicles over five production classes: 313, 314, 315, 507 and 508. The three-car units worked inner-suburban services on the Strathclyde Passenger Transport rail network in and around Glasgow, most typically on the Argyle, North Clyde, Cathcart Circle, Paisley Canal and Inverclyde lines. Current of 25 kV collected from the overhead line by the pantograph passed from the transformer in the intermediate trailer to four 110 horsepower direct current traction motors under each driving car. The fleet was withdrawn from service in 2018 and 2019 because it did not meet the Persons with Reduced Mobility accessibility requirements.
