Class 170 Turbostar

The Class 170 Turbostar is one of the largest fleets of new generation DMUs built post-privatisation. The Class 170 typically operates on regional and long-distance (cross country) services and is a development of the Class 168 Clubman DMU [1]. Indeed later built 168s and 170s have a very close resemblance (some Class 170s have been re-classified as Class 168/3s). The follow-on Turbostar DMUs Classes 171 and 172 also look near identical meaning the Turbostar "look" is a very common one on British rails.
