Dear Patsy
RAILWAY TELECOMMUNICATIONS MASTS
During questions on 22 June, you asked me whether the telecommunications masts which have been erected on the West Coast Main Line were now operational and I agreed to let you know when they will come into operation. I am writing to explain the latest position.
As you are aware, these masts were originally installed as part of a proposed new signalling system for the West Coast, Modernisation this known as the Train Control System (TCS). In the event, TCS was not deliverable and the modernisation project is proceeding with conventional signalling. However, Network Rail is also in the process of implementing a new communications system known as the Global System for Mobile Communications for Railways (GSM-R). The masts which were installed as part of the TCS project will be used to deliver GSM-R on the West Coast Main Line. Some of the masts are already operational supporting an interim Voice Radio System which is being used on some re-signalled sections.
GSM-R will replace existing outdated systems and improve safety by enabling high priority emergency calls to connect drivers and signallers within two seconds of an emergency and enable signallers to communicate with all trains in an area. It will implement a key conclusion of the Cullen report into the Ladbroke Grove accident and also enable compliance with European legislation relating to the interoperability of rail systems.
A pilot trial is due to start in Strathclyde in Winter 2004 to test the system thoroughly before a national roll-out which will give priority to the more heavily used sections of the network. GSM-R should be operational on all TENS routes, including the West Coast Main Line, and in areas where the existing communications infrastructure is in poor condition by Winter 2006. The programme for coverage of other routes is still being reviewed.
I am placing a copy of this letter in the library of the House.
Yours sincerely
