2. A circuit for measuring the rated force of a rail brake, composed of an electric coil of this brake placed on a rail characterised in that it has an immobile electric measuring coil (4) placed in a lengthwise recess (5) of the section of the rail head (6), connected, via an integrating unit (3) and a rectifying unit (2), with a meter (1), where the units are connected, via a feeder (7), with a control panel (8) which, in turn, is connected, via a feeder (12), with the electric coil (11) of the brake.<IMAGE>
