This project includes over 330 global system for mobile communications-railway (GSM-R) 1800 MHz base transceiver stations (BTS) on greenfield and existing radio sites. UGL is responsible for the radio frequency (RF) coverage planning, site selection and EME analysis. Duplicated core network switching centres are located at diverse sites with automated changeover in the event of a major incident.
The network contains 115 control consoles located at signal boxes, sophisticated dispatch terminals in control rooms and 77 kilometres of leaky feeder systems in tunnels. The 330 BTS sites are connected to the switching centres and control points by a high-speed fibre optic network using Dense Wave Division Multiplexing (DWDM) technology.
UGL was also responsible for the deployment of a sophisticated Network Management System (NMS) which allows detailed monitoring and integration of all network elements from the Network Operations Centre (NOC), or by remote dial in for maintenance support.
A sub system provides actual signal strength measurements from each site ensuring the integrity of both equipment and antenna systems.
The electrified rail network utilises almost 1,000 multi-car train sets which were fitted with radio equipment to allow train drivers and guards to communicate with signallers and to receive and generate vital emergency messages using location-based message addressing.
UGL’s contract included training to TfNSW for engineering and field staff enabling them to manage and control the DTRS network. A long term Through-Life-Support contract with logistic services and maintenance was also included within the contract.
