A diesel-electric locomotive includes an assembly including adiesel 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 diesel locomotive which is coupled to the locomotive in a traction grouping in railway vehciles.
A diesel electric locomotive includes a main generator for a drive apparatus and an auxiliary generator for auxiliary appliances, connected to a diesel engine. The main generator is connected by a first rectifier to the direct current traction intermediate circuit of the drive apparatus. The auxiliary generator is connected via a second rectifier to a direct current auxiliary operation intermediate circuit of the auxiliary appliances. The main generator is likewise connected via the rectifier and a DC/DC converter to the direct current auxiliary operation intermediate circuit.
diesel locomotive with a frame and at least one preferably diesel-electric drive unit, the frame being supported on at least two bearing sections, in the area of which the frame rests on wheel frames, and having at least one preferably dropped middle section extending between two bearing sections, wherein the middle section (B) substantially comprises two side parts (4, 4′) spaced apart from each other, each of which has a lower chord (6, 6′) and upper chord (5, 5′) running in longitudinal direction and at least one stay (7, 7′; 27, 27′) connecting the lower chord to the upper chord, and in that at least one drive unit (10, 10′) is arranged in the middle section (B) of the bogie frame
