FIELD: engineering of regulating devices, mounted along routes of trains and locomotives. ^ SUBSTANCE: device has contacts of green and yellow signal relays and two light diode circuits of different radiation types. Selected connection scheme of light diode circuits to power source though contacts of signal relays makes possible receiving of three colors of traffic lights indications, green, red, and yellow, in case of presence of light diode circuits of green and red colors. ^ EFFECT: substantially simplified construction, lower manufacturing costs and lower operation costs. ^ 1 dwg
