The Class 220 ''Voyager'' is a class of diesel-electric high-speed multiple-unit trains built in Belgium by Bombardier Transportation in 2000 and 2001. They were introduced in 2001 to replace the 30-year-old InterCity 125 and Class 47 fleets operating on the Cross Country Route, initially for Virgin Trains and since 2007 by CrossCountry. ==Technical details== All coaches are equipped with a Cummins QSK19 diesel engine of at 1800rpm. These power a generator which supplies current to motors driving two axles per coach,〔 (【引用サイトリンク】 Class 220 data ) 〕 with one axle per bogie powered.〔(M-Size Bogies B5000 For Coach and EMU Applications )〕〔(B5000 bogies bombardier )〕 Voyagers have both air and rheostatic brakes. They are fitted with Dellner couplers, like the Class 222, operated by East Midlands Trains and the Class 390 ''Pendolino'' electric trains used by Virgin 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 adaptive couplings a failed 220 or 221 can also be assisted by any air braked locomotive such as a Class 37, 47 or 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 and a maximum range of approximately between each refuelling. Their route availability is very good being RA 2〔 - in part due to the lightweight bogie design. Class 220 units do not have automatic sanding equipment, and instead have "one-shot" sanders which activate when all of the following conditions are met: #The emergency stop button has been pressed; #Wheel slip has been detected; #Train speed is over . As it was necessary to take the train out of service for refill following the deployment of sand, Bombardier fitted a second sand bottle, allowing two uses before the train would need to be withdrawn from service. The CrossCountry fleet was modified between February and June 2011. All ''Voyagers'' are maintained at the dedicated Central Rivers TMD near Burton-on-Trent. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「British Rail Class 220」の詳細全文を読む スポンサード リンク
