This drive system represents the first hybrid vehicles in and for China. The three-part vehicles are driven with two RailPacks 400DE, both with a 375 kW diesel engine and a 345 kW generator. The first three RailPacks have already been delivered to the customer Changchun Railway Vehicles Company Ltd. (CRC). They underwent a range of comprehensive tests at the company's own test ring in Changchun and at Beijing Jiaotong University. Next year the rail vehicle is to be tested and approved by the China Railway Corporation, the national railway operator of China.
The Chinese vehicle manufacturer has planned 30 of these hybrid vehicles. This is an absolute first for China. They are to be used in the routes in the city suburbs that have not yet or have only partially been electrified. Outside these areas, daily service runs smoothly with the Voith RailPack 400DE, while inside towns and cities the operator can run the vehicles with electrical drive, with zero emissions. The hybrid vehicles reach top speeds of up to 120 km/h with diesel-electric drive. The RailPacks 400DE also feature a quick switch system from electric to diesel-electric. The Voith drive system is also designed to withstand extreme climate demands: it can handle temperatures down to minus 40° Celsius.
The cooperation between CRC and Voith in this pioneering rail vehicle project is based on Voith's readiness to use existing, tried and tested system technology to develop customer-specific solutions. The Chinese partner regarded the diesel-hydraulic and diesel-mechanical RailPacks that have already been put to the test thousands of times with their reliable components as a convincing argument for the RailPack 400DE.
