The Class 717[5] is an electric multiple unit used by Govia Thameslink Railway, on its Great Northern routes. They are manufactured by German rolling stock manufacturer Siemens, mainly for services from Moorgate station, in London. A total of 25 six-car units are to be built. Starting in January 2019, limited preview services began[6] and the phase-in of regular service began in March 2019.[7][8]

History[edit]

Upon winning the Thameslink, Southern and Great Northern franchise, Govia Thameslink Railway (GTR) announced that it would seek to replace the existing Class 313 units (which were 40 years old by 2016) operating on services to and from Moorgate, with up to 25 six-car units intended to be procured.[9] In December 2015, GTR announced that it had selected Siemens to provide this new fleet as a follow-on order from the main Class 700 order, with entry into service expected from March 2019.[10] The order was finalised in February 2016.[11][12]

A significant difference between Class 717s and the earlier Class 700s is the provision of emergency end doors. These are required for evacuation of passengers[5] while in the Moorgate tunnels.[13]

Siemens began testing the Class 717 units in Germany during June 2018.[14] The first unit operated a single preview service in late September 2018, with gradual introduction from the spring of 2019.[6]
