Ren Xiangwu, the project leader at CRRC Yongji Electric Co., Ltd., introduced that this new energy shunting locomotive for urban rail transit features low noise and zero emissions. It is suitable for scenarios such as traction, shunting, and rescue operations of urban rail transit vehicles.

It is reported that this locomotive uses power-type lithium iron phosphate batteries as the vehicle's traction batteries, with a battery capacity of up to 800 kWh. These batteries have high safety, high energy density, long cycle life, and good charge-discharge performance. In terms of power, the locomotive's traction motor uses a permanent magnet synchronous motor, which can single-handedly start and pass through a 5% gradient with a load of 220 tons at a speed of no less than 10 km/h. The comprehensive range can reach up to 120 km.
