Requirement: ARTC have undertaken a major project to resignal the line between Spencer Junction and Tarcoola in South Australia. Enabling greater efficiency of train movements through this section of the rail network was one of the main goals. In addition, it was also necessary to offer a solution that would provide reliable clear/occupied status in remote areas. Solution: The project was realised with the Frauscher axle counting system FAdC to- gether with Frauscher wheel sensors RSR180. Train detection is distributed along the track in cluster – small axle counter equipment cabinets. Three different technologies came into operation to establish communication in bet- ween these clusters. Fibre optic or a SHDSL network were used for short di- stance communication.
