201307 – Strike & Crivelli – Using Axle Counters for Block Control the ARTC Experience

Utilisation of axle counters over the last two decades has been expanding to encompass many
signalling and non-signalling applications. Their uses range from simple triggering devices for
wayside equipment such as hot box detectors and weighing systems, to more complex train detection
systems for train signalling.

The use of high quality fail safe (SIL4) axle counters for occupancy detection have been widely
applied in Australia for short track sections where communications are reliable and visual cues
provide an extra level of safety confidence. Life cycle costs can be substantially lower with axle
counters when compared to other technologies and with advancements in technology; capital costs
can also be reduced.
