Disclosed is an engine control system for one or more engines of one or more vehicles. The engine control system includes an electric power supply unit formed by an engine 21 and an electric power generator 22 for generating electricity by the driving of the engine 21. An electric power conversion unit 24 is provided for converting electric power generated by the electric power generator. Also provided is an electric power cutting-off unit 29 for cutting off connection between the electric power supply unit and the electric power conversion unit 24. A drive control unit 27 controls the electric power supply unit and the electric power conversion unit. A running-purpose main electric motor 25 is driven by the electric power converted by the electric power conversion unit and a vehicle control unit controls running of the vehicle. The engine control system has a running mode in which the main electric motor is driven by electric power generated by the electric power generator by the driving of the engine or electric power supplied from outside of the vehicle and a test mode in which the electric power cutting-off unit cuts off connection from the electric power generator to the electric power conversion unit and a running check test of the engine is performed. The engine 21 may be a Diesel internal combustion engine and the vehicle may be a locomotive. The external power may be supplied by overhead power cables.
