FIELD: transport engineering.
SUBSTANCE: invention relates to method of transmission of control signal Is to vehicle 5 set into operation by traction current Ia in placed 20 of input of traction current into traction current conductor 15, vehicle being electrically connected with traction current conductor 15 through traction current receiver 10. traction current receiver 10 forms, together with traction current input place 20, track section 25. Control signal Is is supplied to traction current conductor 15 and is received at side of vehicle inductively coupled withy traction current conductor 15 through current sensor 45, 50. Current sensor 50 lying out of track section 25 is used to prevent action of frequency interference of traction current in transmission of control signal Is.
EFFECT: reduced influence of interference in contact wire onto control signal.
