Two British Rail Class 220 units operated by CrossCountry coupling to form a longer train

All coaches are equipped with a Cummins QSK19 diesel engine of 750 hp (560 kW) at 1800 rpm. These power a generator which supplies current to motors driving two axles per coach, with one axle per bogie powered. Voyagers have both air and rheostatic brakes. They are fitted with Dellner couplers, like the Class 222 operated by East Midlands Railway and the Class 390 Pendolino electric trains used by Avanti West Coast, meaning they can be coupled in rescue/recovery mode (air brake only) in the event of a failure. 220s and 221s can also be easily assisted by Dellner fitted Class 57s (Thunderbirds) in the event of a failure. By use of adaptor couplings a failed 220 or 221 can also be assisted by any air braked locomotive such as a Class 37, Class 47 or Class 66 or even an HST. The units can work in multiple with Class 221 units but not Class 222 units as the electrical connections of the Class 222 units are incompatible with the Class 220. The Class 220s and closely related Class 222s have B5005 bogies, which are distinctive as they are of inside-frame design and so the axles are supported by bearings behind the wheels, meaning the outside face of the wheel is visible. The related Class 221 Super Voyager has outside-frame bogies and hence a more conventional appearance.
