Abstract: A diesel-electric locomotive includes a diesel engine which is connected to a generator. A cable originates from the generator to supply electrical power to a drive unit. An additional cable originates from the generator to supply electrical power to secondary appliances. The additional cable further includes a transformer therein.

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.

Abstract: A diesel-electric locomotive includes an assembly including a diesel engine and a generator, a drive unit and a control device, connectable to control devices of other locomotives. Further, a traction grouping includes at least two such diesel-electric locomotives, the locomotives being connected to one another by a control connection. There is provision for a power line to be present with terminals for power lines of other locomotives. In the traction grouping, the locomotives are connected to one another by a power line.
