Arrangement for driving a locomotive (LOK) having various energy-provision systems, - with a locomotive (LOK) which includes a main energy-provision system as the main system (HA), and a drive system with traction motors (FM), wherein energy provided by the main system (HA) is fed as drive power to the drive system and used by the latter to move the locomotive (LOK), - with a carriage (WA) which includes at least one further energy-provision system as an ancillary system (HS1), wherein the at least one ancillary system (HS1) is used to feed drive power to the drive system at different times from the main system (HA), - in which components which can be used both by the main system (HA) and by the at least one ancillary system (HS1) are implemented only once, such that these components are jointly used both by the main system (HA) and by the at least one ancillary system (HS1), and - in which components which can be used only by the at least one ancillary system (HS1) are arranged on the carriage (WA), - wherein the required components of the main system (HA) are completely arranged on the locomotive (LOK), such that autonomous operation of the locomotive (LOK) is made possible, - wherein the at least one ancillary system (HS1) is AC-based and the carriage (WA), as components of the at least one ancillary system (HS1), has a current collector, a main switch, a transformer and a four-quadrant actuator , - wherein the locomotive (LOK), as components of the main system (HA), has a converter or frequency converter for the traction motors (FM), - wherein an intermediate circuit, which is arranged between the four-quadrant actuator and the converter, is arranged optionally and at least partially on the carriage (WA) or on the locomotive (LOK). - with a locomotive (LOK) which includes a main energy-provision system as the main system (HA), and a drive system with traction motors (FM), wherein energy provided by the main system (HA) is fed as drive power to the drive system and used by the latter to move the locomotive (LOK), - with a carriage (WA) which includes at least one further energy-provision system as an ancillary system (HS1), wherein the at least one ancillary system (HS1) is used to feed drive power to the drive system at different times from the main system (HA), - in which components which can be used both by the main system (HA) and by the at least one ancillary system (HS1) are implemented only once, such that these components are jointly used both by the main system (HA) and by the at least one ancillary system (HS1), and - in which components which can be used only by the at least one ancillary system (HS1) are arranged on the carriage (WA), - wherein the required components of the main system (HA) are completely arranged on the locomotive (LOK), such that autonomous operation of the locomotive (LOK) is made possible, - wherein the at least one ancillary system (HS1) is AC-based and the carriage (WA), as components of the at least one ancillary system (HS1), has a current collector, a main switch, a transformer and a four-quadrant actuator , - wherein the locomotive (LOK), as components of the main system (HA), has a converter or frequency converter for the traction motors (FM), - wherein an intermediate circuit, which is arranged between the four-quadrant actuator and the converter, is arranged optionally and at least partially on the carriage (WA) or on the locomotive (LOK). <EOS>
