To solve the problem of maintaining equipment on high-speed railway lines with long ramp,this paper designs an electric drive traction system for engineering vehicles suitable for long ramp,by increasing the power of the diesel engine and combining the good traction and braking performance of the electric drive.The traction system can adopt a two-vehicle fixed couple operation mode, and the vehicle has high power and strong braking ability. It effectively solves the problems of insufficient power for uphill and high temperature of downhill brake shoes for traditional maintenance vehicles running on long ramp. Compared with HXN5 freight locomotive, the designed electric drive engineering vehicle has the characteristics of light weight, small inertia and short braking distance, which greatly reduces the possibility of damage to the rail during maintenance. Compared with HXN5 freight locomotive, which can only be pulled forward and cannot be driven backward, the new electric drive engineering vehicle can travel forward and backward, which greatly reduces time waste and improves maintenance efficiency.Type test result of whole vehicle and actual test result of Xicheng high speed railway show that the electric drive rail engineering vehicle using this traction system can reach a maximum speed of 107 km/h uphill, and can run stably within 100 km/h after applying resistance braking as the vehicle being downhill, and the electric drive traction system is stable and reliable.
