FIELD: transportation.
SUBSTANCE: electromagnetic track brake comprises an electromagnet attached to the bogie frame and a switching device. A third rail with rail poles on it is laid on the railway track. Rail pole position sensors connected by their outputs to the inputs of the control device are located near the electromagnet pole. The control device output is connected to the input of the switching device connecting the electromagnet coil to the power supply source. A brake force control device output is connected to the other input of the control device. A retainer comprising a pin is attached to the bogie frame near the electromagnet.
EFFECT: increasing the reliability and wear resistance of an electromagnetic track brake.
