Claim 0:
1. A locomotive drive arrangement, the arrangement comprising:
a locomotive having a drive system and a main energy-provision system being a main system, said main system being configured to feed drive power to said drive system for use by said drive system to move said locomotive;
a railroad car having at least one further energy-provision system being an ancillary system, said ancillary system being configured to feed drive power to said drive system at different times from said main system;
wherein components that are required by said main system are disposed entirely on said locomotive to enable an autonomous operation of said locomotive;
wherein components to be used both by said main system and by said at least one ancillary system are implemented only once; and
wherein components to be used exclusively by said at least one ancillary system are disposed on said railroad car; and
wherein, with said at least one ancillary system being based on an energy storage mode, said railroad car includes the following components of said at least one ancillary system:
an energy storage device;
a partial intermediate circuit; and
an energy converter configured to convert energy received from said energy storage device into a desired intermediate circuit voltage;

wherein, with said main system being a diesel drive, said locomotive includes the following components for an autonomous, diesel-based operation in a predetermined first track:
a diesel engine;
a generator for generating a required electrical power;
a partial intermediate circuit;
a three-phase asynchronous motor being a drive motor;
a cooling system for said drive motor;
a compressed-air braking system; and
a compressor system for said compressed-air braking system

said locomotive being configured to choose, depending on a given section of track, between the main system and the ancillary system, by connecting the respectively required components to one another via a selection circuit, to thereby operate the locomotive in dependence on the given section of track; and
a DC electrical connection between said partial intermediate circuits of said railroad car and said locomotive for selectively forming an operational locomotive-railroad car twin unit, by connecting said at least one further energy-provision system of said railroad car with the drive components of said locomotive.
