1. A method for the operative monitoring of track brakes, in which an electric current passes through a winding of a brake magnet, the method comprising:

  • measuring the electric current (i2, i4);

    comparing a time profile of the measured current with a stored time profile of a reference current (i1, i3); and

    wherein local minimum values (e min) and/or local maximum values (e max) of the measured current (i4) are determined, and wherein only the time profile of the measured current (i4) with an increase in the current (i4) is subjected to comparison with the reference current (i3).
