An axle counter which compares axle passage pulses generated in an electromagnetic rail contact with a predetermined threshold value and, when this threshold value is exceeded, feeds an axle counter pulse to presence-of-trains indicating equipment, is equipped with overwritable memories (SMA, SMI) for storing this threshold value. In response to a setup command entered manually by depressing a key or transferred from a distant control facility (STW), the memories can be overwritten with a current axle passage pulse value or a statistically determined value corresponding to an average axle passage pulse. This eliminates the need to reposition the rail contact at regular intervals and permits this repositioning to be replaced by an adaptation of the threshold value to the axle passage pulses, which change as a result of rail wear, for example.
