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 two operators, CrossCountry (25 sets) and Grand Central (two sets). CrossCountry sets had their tilt function disabled in 2008 to improve reliability and reduce maintenance costs, and Grand Central sets do not use theirs, although they remain in place. There are also a number of additional sets in storage, having been stood down from Avanti West Coast in December 2024. ^[9]
