HC Deb 31 March 2003 vol 402 c516W
Mr. Gray

To ask the Secretary of State for Transport how many communications masts will be required for the new GSM-R digital network. [105416]

Mr. Jamieson

I understand that Network Rail is upgrading its analogue radio systems network of around 1,400 telecommunications masts to a national digital network of approximately 2,000 masts. The increased number arises from the extended coverage of the new system across the entire rail network, including all tunnels and cuttings.
