Abstract
A method for operating an axle counter system for monitoring the occupation status of a track section being limited by counting positions which have at least one detection point and at least one counting position a set of redundant detection points, includes the steps of: (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; (c) determining the number of remaining axles within the track section; and (d) outputting a track occupation status. 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. In step (c) the counter values of the selected detection points are used for determining the number of remaining axles and the counter values of the non-selected redundant detection points are ignored.
