The British Rail Class 221 Super Voyager is a class of tilting diesel-electric multiple unit express passenger trains built in Bruges, Belgium and Wakefield, by Bombardier Transportation in 2001–02.

The class is similar to the Class 220 Voyager, but was built with a tilting mechanism enabling up to six degrees of tilt to allow higher speeds on curved tracks. Additionally, most have five coaches, and they have a different bogie design. They have a maximum speed of 125 mph (200 km/h).

The trains are divided between three operators, Avanti West Coast (13 sets), CrossCountry (25 sets) and Grand Central (2 sets).^[2] CrossCountry sets had their tilt function disabled in 2008 to improve reliability and reduce maintenance costs.
