The British Rail Class 222 is a diesel multiple unit high-speed train capable of 125 mph (200 km/h). Twenty-seven units have been built in Belgium by Bombardier Transportation.
The Class 222 is similar to the Class 220 Voyager and Class 221 Super Voyager trains used by CrossCountry and Virgin Trains, but it has a different interior. The Class 222 trains have more components fitted under the floors to free up space within the body. Since 2009 East Midlands Trains has been the only train operating company using Class 222s.
All coaches are equipped with a Cummins QSK19 diesel engine of 750 hp (560 kW) at 1800 rpm. This powers a generator, which supplies current to motors driving two axles per coach. Approximately 1,350 miles (2,170 km) can be travelled between each refuelling.
Class 222 have rheostatic braking using the motors in reverse to generate electricity which is dissipated as heat through resistors situated on the roof of each coach; this saves on brake pad wear.
In common with the Class 220s, B5000 lightweight bogies are used - these are easily recognisable since the entire outer surface of the wheel is visible, with inboard axle bearings.
The Class 222 are fitted with Dellner couplers, as on Class 220 Voyager and Class 221 SuperVoyager trains, though these units cannot work together in service because the Class 222 electrical connections are incompatible with the Class 220 and Class 221 trains.
All Class 222 units are maintained at the dedicated Etches Park depot in Derby, just south of Derby station.
