The deal will see BT provide services to several hundred Network Rail sites, including offices, control centres, depots, signal boxes, and level crossings.

According to the company, the new network will be integrated with Network Rail’s FTN project, which is aiming to renew and replace 16,000km of copper cabling and 11,000km of fibre optic cabling. Network Rail plans to launch a new digital driver-to-signaller radio system.

The company also says it hopes the deal will result in more reliable communications, increased efficiency and reduced costs.

John Dovey, president UK corporates, BT Global Services, said: We are delighted to secure this contract with Network Rail. It is an organisation that is subject to more public scrutiny than most and its technology infrastructure needs to be reliable, cost-effective and fit for the challenges of the future. The new IP network will be central to bringing this vision to life.

Network Rail manages over 20,000 miles of rail track across the UK carrying three million passengers daily. The organisation is responsible for the tracks, signals, tunnels, bridges, viaducts, level crossings and stations.
