Estimating the number of axle counters for single-track lines

The article attempts to determine the estimated number of axle counters for a single-track line, taking into account the number of simple turnouts, double slip switches, and simple turnouts with shared insulated sections. The relationships provided by the authors are their original reflections, but they have been supported by examples of the implementation of such systems in EU railways. The issue addressed is significant for the design of railway traffic control devices for regional lines. The paper provides examples of the implementation of computerized traffic control posts equipped with axle counting track circuits.One of the stages in designing railway traffic control systems is determining the number of track vacancy detection sections and the number of axle counters. The sum of track and turnout vacancy detection sections is easy to determine, but calculating the required number of axle counters to safely verify the vacancy of tracks and turnouts is not so obvious. It is easy to make a mistake here due to the various configurations of track layouts. (…)
