The Class 168 Clubman is a British diesel-hydraulic multiple unit passenger train used on Chiltern Line services between London Marylebone and the West Midlands. The trains were built by Adtranz at the Derby Litchurch Lane Works in several batches from 1998.
The first batch was classified 168/0 under TOPS and resembled the Class 165 units previously built by BREL York. The Networker-design cab was an interim solution pending the design of a completely new cab for further Turbostar batches. Subsequent builds, subclassed as 168/1 and 168/2, were constructed at the same time as the Class 170 Turbostar and thus are part of the Turbostar family of trains.
