Abstract
An assembly for supplying electrical energy to electrical traction motors in a rail vehicle, wherein the assembly includes at least one internal combustion engine, a generator allocated to the at least one internal combustion engine for generating the electrical energy, wherein the generator is mechanically coupled to the internal combustion engine such that it is driven by the internal combustion engine upon generator operation of the generator, a rectifier for rectifying an electrical alternating current generated by the generator, a direct voltage intermediate circuit that is electrically connected to the generator via the rectifier, a generator inverter that is present in addition to the rectifier or that is the rectifier operated in the inverter mode, wherein the generator inverter connects the direct voltage intermediate circuit to the generator in order to operate the generator in a motor mode as a motor, and a control for controlling the motor mode of the generator.
