The invention provides a train rescue control system which is used for a fault train side and comprises a first switching module coupled between a storage battery of a train and an intermediate direct current loop; the control module is electrically connected with the first switching module and a traction inverter of the train and is configured to be used for controlling the first switching module to conduct electric connection between the storage battery and the intermediate direct-current loop when the fault train is dragged and driven to reach the preset rotating speed. The traction inverter is controlled to obtain direct current input from the intermediate direct current loop, invert the direct current input into alternating current with preset frequency and output the alternating current to an excitation system of the fault train to establish excitation; and responding to successful excitation establishment, controlling a traction inverter to reverse, obtaining alternating current input from the excitation system, rectifying the alternating current input into direct current, outputting the direct current to an intermediate direct current loop, and parallelly supplying power with a storage battery. The rescue cost can be greatly reduced, and the rescue efficiency is improved.
