The British Rail Class 222 is a diesel-electric multiple unit high-speed train capable of 125 mph (200 km/h). Twenty-seven units have been built by Bombardier Transportation.
The Class 222 is similar to the Class Class 220 Voyager and Class 221 SuperVoyager trains used by CrossCountry and Virgin Trains but units have a different interior, which is less cramped than the Voyagers. The Class 222 trains have more components fitted under the floors to free up space within the body.
Technical details
Below are the technical details for the Class 222 Meridian / Pioneer.
Engine
All coaches are equipped with a Cummins QSK19 diesel engine of 750 hp (560 kW) at 1800rpm. 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.
Formation
Class 222 units are currently running in the following formations:
East Midlands Trains: seven cars with 236 standard seats and 106 first-class seats.
Coach A - Standard Class with driving cab and reservable space for four bikes
Coach C - Standard Class
Coach D - Standard Class
Coach E - Standard Class with Shop/Buffet counter
Coach F - First Class
Coach G - First Class
Coach J - First Class and driving cab
East Midlands Trains: five cars with 192 standard seats and 50 first-class seats.
Coach A - Standard Class with driving cab and reservable space for four bikes
Coach B - Standard Class
Coach C - Standard Class
Coach D - Standard Class / First Class
Coach G - First Class and driving cab
First Hull Trains: four cars
Coach A - First Class and driving cab
Coach B - First Class / Standard Class
Coach C - Standard Class
Coach D - Standard Class with driving cab and reservable space for bikes
Brakes
Class 222 units make use of rheostatic braking (the same as the Class 220 Voyager and Class 221 SuperVoyager trains). This system brakes the train by using the motors of the train in reverse, to generate electricity which is then dissipated as heat through resistors situated on the roof of each coach. This slows the train and saves on brake shoe wear.
Couplers
The Class 222 are fitted with Dellner couplers, as used on the Class 220 Voyager and Class 221 SuperVoyager trains, though these units cannot be coupled to work together in service because the electrical systems are incompatible. They can be coupled to push or pull each other though if a unit becomes faulty. The first-class end of the train is indicated by a yellow bar on the coupler.
