Sentrarand Signalling Upgrade
ACTOM Signalling, the ACTOM group’s railway signalling business unit, recently completed a multi-million rand signalling upgrade contract for Sentrarand marshalling yard, near Bapsfontein, Gauteng.
The contract involved a comprehensive upgrade of the signalling system serving Sentrarand and the total of 28 stations that make up the network of freight lines radiating from the marshalling yard. These stations are controlled and monitored by Sentrarand’s centralised traffic control (CTC) system.
The upgrade project, dubbed “Sentrahub”, mainly comprised migration from coaxial copper cable to single-mode optic fibre cable for the interlocking and remote control systems on the block sections between stations.
ACTOM Signalling also installed other state-of-the-art signalling equipment in place of existing outdated equipment as part of the upgrade. This comprised Thales AZLM axe-counters to replace the old Telkor axle-counters and Vital 21 Fail Safe Data Transceiver (FSDT) equipment as part of the modernisation of the interlocking system.
The existing CS90 remote control system also had to be adapted and upgraded to enable it to communicate with the new axle-counters via optic fibre cable.
The upgrade contract, which commenced in April 2012, was completed in January this year.
