1 Introduction1.1 Background to the ProjectRailCorp currently operates an analogue train radio system known as MetroNet <strong>for</strong> operationalcommunications between signallers and train drivers. This system has reached the end <strong>of</strong> itsserviceable life and requires replacement. The New South Wales Government and RailCorphave begun work on the implementation <strong>of</strong> a Digital Train Radio System (DTRS) which willreplace this analogue system and address a number <strong>of</strong> recommendations from the WaterfallSpecial Commission <strong>of</strong> Inquiry (WSCOI).The primary objectives <strong>of</strong> the DTRS project are to:• provide continuous radio coverage across 100% radio <strong>of</strong> RailCorp’s electrified network;• replace and improve on the current RailCorp MetroNet communications system;• provide a technology plat<strong>for</strong>m <strong>for</strong> future development <strong>of</strong> the automatic train protectionsystem (ATP); and• adopt best management and administrative practices while complying with the principles <strong>of</strong>ecologically sustainable development.The DTRS will provide secure and reliable voice and data communications via a GlobalSystems Mobile – Railway (GSM-R) plat<strong>for</strong>m. It will be used by train controllers, train drivers,train guards and signallers. The system is designed to allow <strong>for</strong> growth in both the size <strong>of</strong> thenetwork and the number <strong>of</strong> services using it. It will be compatible with communications systemsused by other users <strong>of</strong> the network, e.g. freight operators.The DTRS will provide 100% radio coverage along approximately 1455 kilometres <strong>of</strong> theRailCorp electrified network as well as in 66 tunnels covering approximately 70 kilometres andhas an expected design life <strong>of</strong> at least 15 years.The DTRS will include:• a main switching centre at a CBD location;• a geographically separated back-up switching centre at Homebush;• on-train equipment in approximately 675 train cabs;• about 250 base transceiver stations (BTS) as well as other base stations in tunnels;• approximately 65 dispatcher terminal units; and• capability to provide staff with handheld terminals.The DTRS will provide continuous coverage along the entire RailCorp electrified network <strong>for</strong> ontrainradios and permit at least 14 simultaneous voice calls from each base station.Page 7 <strong>of</strong> 64
