Operation and maintenance of the Country Regional Network (CRN) was transferred to John Holland on 15 January 2012, with train control functions shifting to a newly created CRN control centre at Mayfield.
The centre was fitted out specifically for train operations with all supporting train control technology. 4Tel was contracted to deliver all train control technology, including: train control systems (train order and Rail Vehicle Detection), telemetry systems, voice and train communication systems, supporting systems for operations and maintenance, and data networks for all system and operational connectivity. All design, procurement, installation, configuration, testing and commissioning was done within a 12 month mobilisation period to enable operations to commence on 15 January 2012.
4Tel provides ongoing support for the CRN control centre systems including the provision of a 24/7 technical support desk working directly with the network control staff. All systems have been configured with system health monitoring and logging, in addition to alarm management provided via 4Site.
After 18 months of operation, the benefit of 24/7 onsite maintenance and supporting structure is now being realised. System availability exceeds all targets and industry benchmarks. With callout reductions and improved health monitoring, the costs for support of train control and signalling infrastructure is now being reduced.
