FIELD: transport.
SUBSTANCE: invention relates to brakes at railroad rolling stock. Proposed brake comprises electromagnet, wheel or wheel center with poles made of magnetic material arranged thereon. Poles of wheel or wheel center are located between electromagnet poles. Transducers of position of wheel or wheel center poles are arranged along the circle nearby electromagnet plunger poles. Outputs of said pickups are connected to control device inputs. Control device output is connected to input of switch connecting electromagnet winding to power supply. Another input of control device is connected to output braking instruction source.
EFFECT: higher reliability.
