Axle counter technology is a proven, reliable method of track vacancy detection suited for a variety of installations. But despite the many advantages this technology can offer it has not rivalled conventional track circuits as a form of track vacancy detection within single line sections in Australia. This perhaps can be attributed to a number of inherent issues that impeded the effectiveness of axle counters system when configured to transmit data over long distances. However, in recent years there have been a number of advancements in both axle counter and telecommunications technology which have overcome some of these inherent issues. This paper investigates whether axle counter technology is now a smarter solution for single line sections, or if conventional track circuits still provide the best solution.
