ABSTRACT:
A diesel-electric locomotive includes an assembly including a diesel engine and a generator, to which a drive unit is connected. The diesel engine is connected to a cooling system holding fluid. The drive unit is electrically connected to a braking resistor. There is provision for the braking resistor to be arranged in the cooling system so as to give off heat to the fluid. For example, the braking resistor is connected to a separate heating voltage source which may be, for example, a voltage source in a second locomotive which is coupled to the locomotive in a traction grouping.
