The Class 221 are similar to the Class 220 Voyager units, but they were built with a tilting mechanism enabling up to six degrees of tilt to allow higher speeds on curved tracks. They have a maximum speed of 125 mph. Currently these trains are divided between two operators, Virgin Trains (21 sets) and Arriva CrossCountry (23 sets). The sets operated by CrossCountry have had their tilting equipment disabled. |
