China: The family of seven models offers output ranging from 1,000 to 2,000 kW, tractive effort from 340 to 510 kN, and a design speed of 100 km/h.
The four- or six-axle vehicles feature a modular design that is also used in other Fuxing vehicles.
The locomotives are equipped with three types of traction systems: a battery pack, a hydrogen system, and hybrid system that uses diesel engine with batteries. The batteries are either LiFePO4, with a capacity of up to 1,260 kWh, or LTO, with a capacity of up to 600 kWh and a stated lifespan of 12 years. Furthermore, the locomotives are equipped with a smart diagnostic system.
The new family of shunting locomotives has been developed in response to China’s decision to limit the service life of diesel locomotives to 30 years with the aim of decommissioning the old vehicles by 2035. In pursuit of this objective, several hybrid locomotives have recently been developed. The new generation includes the FXN3B, FXD3H, CHA3C1, and HXN6. Conversion projects for applying alternative traction at old locomotives are also underway.
