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.

Diesel-electric locomotive

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.

A plurality of semiconductor arrangements arranged on interconnects are cected parallel to one another in a module. The arrangements lie opposite one another in pairs. At least one pair and at most two pairs of semiconductor arrangements are arranged to follow one another in the direction of an axis of the module and are further connected to lead conductors. Positions of the lead conductors with respect to the contacted semiconductor arrangements are the same for each pair of semiconductor arrangements or, respectively, two respective pairs of semiconductor arrangements. Corresponding lead conductors are connected to one another above the interconnects.
