PROBLEM TO BE SOLVED: To provide an electric railroad system which does not require control switching at mutual translation between a stringing section and a non-stringing section, by putting together controllers of charging a battery and feeding to a drive system or the like and by connecting in parallel the battery and the drive system or the like. SOLUTION: The electric railroad system 1 includes a main feeder system 5, a power regulating unit 40, a three-phase induction motor 21 for running drive, a VVVF inverter 20, the battery 35, and a feeder system 22 for auxiliary equipment and the like, and is constituted so that a motor 21 may be driven by power from the stringing 7 in the stringing section, and the motor 21 may be driven by power from the battery 35 in the non-stringing section. The railroad system has a constitution where an input end of the power regulating unit 40 is connected to the main feeder system 5, and an output end is connected to the inverters 20, the feeder system 22 and the battery 35, and includes power control means 50 which sets a charging current to the battery 35 in the stringing section by using predetermined charging current setting means and controls the power regulating unit 40 so that the battery 35 may be charged by the charging current.
