PROBLEM TO BE SOLVED: To balance an organized rolling stock, improve redundancy attributed to operation, and reduce battery capacity in the organized rolling stock with a battery-driven and inverter-controlled car connected as a train, and to provide provide the most suitable train to a non-electrified line. SOLUTION: This rolling stock has at least one motor car, mounted with an AC motor to drive the car, an inverter to drive it at a variable speed, and a plurality of trailer cars with no motor nor inverter mounted. Batteries are mounted separately on at least two trailer cars, to supply DC power of the batteries to the inverter of the motor car. In rolling stock with a plurality of motor cars and trailer cars connected respectively, at least two trailer cars are mounted with batteries, whose terminals are parallel-connected through a common power line across the respective trailer cars, thereby supplying power to the inverters of the respective motor cars through the power line. |
