Abstract

A system wherein a central control station (4) supplies, through a three-pole cable (66), a peripheral station (6), wherein an electric motor (10) causes a railroad track switch (8) to move between a first and a second limit of travel position. System (1) comprises an electromechanical position sensor (20), coupled with a first and a second capacitor (41, 40), connected in series, for either first or second position, and through three-pole cable (66), with a first and a second inductor (54, 60), respectively, of the control station. A signal generator (46) supplies, at its output, a periodic alternating signal (S), capable of causing the electric circuit, comprising first capacitor (41), connected in series with first inductor (54), or second capacitor (40), in series with second inductor (60), to resound. Central station (4) comprises first and second measuring means (58, 61), respectively coupled with first and second inductors (54, 60) and capable of measuring thereon a resonance voltage peak to measure the position of both position sensor (20) and switch.
