Thales UK has won contracts worth £28.8M to provide railway traffic management systems.
The technology firm will deploy its systems at Network Rail’s Cardiff and Romford operating centres by the end of next year.
Control of Britain’s rail network is planned to move from more than 800 signal boxes into 12 modern rail operating centres over the next three decades.
Robin Gisby, Network Rail’s managing director of network operations, said: “As the number of people and businesses relying on rail continues to grow, it is vital we have the technology to make the best use of Britain’s rail infrastructure.
“The traffic management which will be deployed on the network uses tried and tested technology used on railways around the world to help deliver a leaner, more efficient and reliable network.”
