The invention concerns a method for operating an axle counter system (AC3,) for monitoring the occupation status (F, O) of a track section (TS1, TS2) being limited by counting positions (CP1, CP2, CP3), wherein at each counting position (CP1, CP2, CP3) at least one detection point (DP1, DP2, DP3) and at at least one counting position (CP1, CP2, CP3) a set of redundant detection points (DP1, DP2, DP3, RDP1, RDP2, RDP3) is provided, said method comprising: (a) incrementing or decrementing axle counter values (#) in dependence of the moving direction of a passing axle; (b) transmitting the axle counter value (#)to an axle counter evaluator (ACE3); (c) determining the number of remaining axles within the track section (TS1, TS2); and (d) outputting a track occupation status (F, O); characterised in that prior to step (c) for each counting position exactly one detection point is selected for further processing independent of the selection at any other counting position; that in step (c) the counter values of the selected detection points are used for determining the number of remaining axles and that the counter values of the non-selected redundant detection points are ignored.
