Abstract: Operative monitoring of track brakes involves passing an electric current through a winding of a brake magnet, measuring the electric current and comparing the temporal progression of the measured current with a saved temporal progression of a reference current. Comparison is achieved by calculating the difference between the measured current and the reference current. The difference between measured current and reference current may be temporally integrated and compared with a threshold value. To determine a magnetic coupling between track brake and track, a calculation may be made as to whether the measured current has local minima and/or local maxima during the activation of the track brake, only the temporal progression of the measured current as the current increases being subjected to a comparison with the reference current. The current may be activated in pulses, with the comparison of the measured current and the reference current being restarted with each pulse.

Abstract: A magnetic rail brake device includes a brake magnet with a solenoid former supporting a solenoid. A horseshoe-shaped magnet core is disposed adjacent to the solenoid former. The horseshoe-shaped magnet core includes a yoke having cheeks that project away from the yoke. Pole shoes are formed at ends of the cheeks. The solenoid includes an upper part, with an upper height and an upper width, and a lower part, with a lower height and a lower width. The solenoid is disposed between the cheeks and engages vertically around the yoke. The upper height is less than the lower height, and the upper width is greater than the lower width. The upper and lower heights are measured parallel to a vertical center axis of the brake magnet, and the upper and lower widths are measured transversely with respect to the vertical center axis.
