FIELD: railway transport; counting of wheels of cars which have passed over pickup installed on rail. SUBSTANCE: wheel counter pickup has summer, filter and voltage stabilizer installed along rail and connected through matching element to one end of connecting line. Connected to other end of line are inputs of frequency current values and upper and lower frequency recorders, supply source, inductance coils, each of which being connected to input of corresponding frequency signal shaper by value of inductance. Output of frequency signal shaper is connected with corresponding input of summer. Output of summer is coupled through filter and matching element with first above-indicated end of connecting line. Coils are arranged inside rail gauge with turns located in horizontal plane at level of passing wheel flange, and distance from plane of rail head to surface of coil guard cover is selected to exceed distance between maximum value of wheel flange radius and minimum value of radius of wheel worn-out rim. EFFECT: enlarged operating capabilities, improved reliability. 3 dwg
