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; and
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 autonomous operation of said locomotive;
said main system being a diesel drive and said at least one ancillary system being an AC drive;
said railroad car carrying the following components of said ancillary system: a current collector, a main circuit breaker, a transformer, and an H-bridge;
said locomotive carrying the following components of said main system: a diesel motor, a generator connected to said diesel motor for generating required electrical power, and an inverter; and
an intermediate circuit between said H-bridge and said inverter being arranged optionally and at least partially on said railroad car or on said locomotive.
