An arrangement for supplying electric energy to traction motors and auxiliaries of a railway vehicle includes, at least two internal-combustion engines, each in combination with an assigned electric machine. At least one internal-combustion engine/machine combination is operated, whereupon the electric machine generates alternating current during a generator mode of operation, which alternating current, in a first operating mode, is rectified by at least one generator rectifier and supplied to a direct-current link in the form of direct current. The direct-current link supplies electric energy to at least one traction motor of the railway vehicle. In the first operating mode, electric energy from the direct-current link is supplied to the auxiliaries via an auxiliaries inverter and via an auxiliaries connector. In a second operating mode the auxiliaries inverter is out of operation, and which is an emergency operation condition, electric energy is supplied to the auxiliaries by the electric machine of one of the internal-combustion engine/machine combination through an emergency operation electric line.
