Network Rail Telecoms Assets

Network Rail operates various essential telecommunication circuits for signalling and electrification control systems, train radio systems, lineside communications, level crossing CCTV, station information and security systems as well as more general IT and business telephony needs. The fixed bearer network infrastructure comprises transmission systems and telephone exchanges linked by a fibre optic and copper cable network that is located mainly within trackside troughing routes on the former British Rail Telecommunications network. (It is the largest private telecoms network in the UK).

Network Rail operates several analogue radio networks that support mobile communication applications for drivers and lineside workers which consist of base stations, antenna systems and control equipment. The National Radio Network (NRN) was developed specifically for the operational railway, it provides radio coverage for 98% of the rail network through 500 base stations and 21 radio exchanges. The Radio Electronic Token Block RETB system is based on similar technology as the NRN and ORN but provides data communication for signalling token exchange as well as voice communication.

Fixed communication at trackside is provided by telephone. These are primarily provided for signallers to communicate with train crew, via telephones mounted on signal posts, and with the public through telephones located at level crossings. GAI-Tronics provides many of the telephones sited on trackside and at level crossings. They also provide Public Access Help Points on platforms and stations to provide passengers with easy access to Information and Emergency control centres.

GSM-R radio systems are being introduced across Europe under EU legislation for interoperability. In the UK, as of March 2014, Network Rail is well underway in the UK implementation of GSM-R to replace its legacy National Radio Network (NRN) and Cab Secure Radio (CSR) systems currently in use.
