The Class 170 "Turbostar" is a 122-strong class of British diesel multiple-unit built by Bombardier Transportation between 1998 and 2005.


The new generation Class 170 multiple units were built at Derby and feature a welded aluminium body structure and hydraulic transmission. Each vehicle is powered by a 422 Horsepower diesel engine providing a maximum unit speed of 100 miles-per-hour. There are no un-powered trailer vehicles.

The engine and transmission are situated under the body and provide drive to one bogie per vehicle. Class 170 units use a BSI automatic coupling to work in multiple and are also compatible with British Rail classes 150, 156 and 158 Sprinters. Class 170 units have been categorised into six sub-classes all with the same basic specifications - the differences are seating arrangements specified by the different operators. This can vary the unit weights by up to 2 tonnes.

The Class 171 units are identical to the Class 170 in structural design except for the coupling type. These were changed from BSI to Dellner type shortly after delivery to Southern Railways, for compatibility with Class 377s if needed.

For Train Simulator, the Class 170 add-on was primarily developed by Thomson Interactive and released by RSC on Steam. Oovee Entertainment assisted with audio development, LUA Scripting and vehicle physics and Richard Holmes created the scenarios for the add-on.

The pack is available standalone or included free with the Edinburgh Glasgow add-on.
