FIELD: transportation; information technology. ^ SUBSTANCE: proposed device for receiving information on a railway vehicle contains amplifier (1), consisting of a power supply terminal, a transformer, two transistors (8) and (9), resistor (5), diode (6), stabiliser (7), relay (11) and capacitor (12). The device also contains interference blanking unit (2), consisting of second and third diodes (13) and (14), second and third resistors (15) and (16), second capacitor (17) and a second relay (18). ^ EFFECT: more accurate reception of information due to reduction of noise effect of power lines on the operation of devices for automatic cab signalling. ^ 1 dwg
