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;
components to be used both by said main system and by said at least one ancillary system each being formed only once as a common component configured to be used jointly by said main system and by said at least one ancillary system;
components to be used exclusively by said at least one ancillary system being disposed on said railroad car;
components required by said main system being disposed entirely on said locomotive to enable an autonomous operation of said locomotive;
with said at least one ancillary system being based on an energy storage mode, said railroad car including an energy storage device as a component of said ancillary system;
said components of said main system of said locomotive including an inverter or a frequency inverter for driving motors of said locomotive; and
an intermediate circuit connected between said energy storage device and said inverter being arranged optionally and at least partially on said railroad car or on said locomotive.
