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 first batch was classified 168/0 under TOPS and resembled the Class 165 units previously built by BREL York.

Network SouthEast originally planned the Class 168 for its expansion of service on the Chiltern Main Line to Birmingham Snow Hill or New Street.

These units were planned to have a higher top speed of 100 mph (160 km/h) and better acceleration than the Class 165 Networker Turbo DMU trains.

The units are receiving new carpets, reupholstered seats, 5G Wi-Fi & charging points, as well as a new revised livery.
