Content: 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. The Class 220s operate in four-coach sets with a carriage mass of between 45 and 48 tonnes and a total train weight of 185.6 tonnes, a top speed of 125 mph (200 km/h) and a maximum range of approximately 1,350 miles (2,170 km) between each refuelling. Their route availability is very good being RA 2 - in part due to the lightweight bogie design. Class 220 units are fitted with an AB Hoses variable rate sanding system. All Voyagers are maintained at the dedicated Central Rivers TMD near Burton-on-Trent . Accidents and incidents
Units have sometimes been stopped by salt water, when storm-driven waves broke over the train at Dawlish in south Devon and inundated the resistor banks, causing the control software to shut down.
