FIELD: physics; control.
SUBSTANCE: invention relates to railway automation means and telemechanics, and is meant for use in systems for controlling train and shunting operations at railway stations. The device for controlling the electric drive of a railroad switch comprises a switch point position sensor, a three-phase electric motor, auxiliary contacts, five line conductors, a resistor, a diode, dc, ac single-phase and three-phase voltage sources and switching relays.
EFFECT: high reliability and low cost of maintenance of an electric switch mechanism.
