The Class 717 is a class of electric multiple unit being constructed for Great Northern by German rolling stock manufacturer Siemens for services from Moorgate, London. A total of 25 6-car units are to be built.
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 are currently 40 years old as of 2016) currently operating on services to and from Moorgate, with up to 25 six-car units intended to be procured. 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 2018.
A significant difference between the Class 700s and Class 717s will be the latter's inclusion of cab end doors. These are required in the Moorgate tunnels to allow for the evacuation of passengers in the event of an emergency.
The order was finalised in February 2016.
