FIELD: transportation.

SUBSTANCE: electromagnetic rail brake with pole fastenings comprises of an electromagnet attached to the bogie frame and a switching device. Pole fastenings of rails are made in the form of poles, which are similar to the poles of the electromagnet. Position encoders of the pole fastening are located next to the electromagnet pole and connected to the inputs of the control device through their outputs. 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 rail brake.
