Between 2021 and 2024 we’re upgrading signalling equipment controlled by our Feltham Area Signalling Centre and Wokingham Signal Box to improve reliability.

State of the art signalling system
A state-of-the-art signalling system is being installed between 2021 and 2024

The Feltham Area Signalling Centre and Wokingham Signal Box jointly covers 80 miles of railway and 500 separate pieces of signalling equipment, on key areas of the South Western Railway (SWR) network including Feltham, Hounslow, Shepperton, Twickenham, Windsor & Eton Riverside and Wokingham.

The existing equipment – such as signals, the traffic light system for the railway, and track circuits, which tell signallers where trains are on the network – dates back to 1974 and is becoming harder and harder to maintain.
In a long-term programme that will run through to mid-2024, we’re renewing that equipment with a modern equivalent that will be more reliable. We’ll also deliver a number of enhancements to improve train performance, as well as renew or upgrade 13 level crossings.

Once all those renewals and upgrades are complete, we will then move control of that equipment from Feltham and Wokingham to Basingstoke and into the Wessex Rail Operating Centre (ROC).

Digital railway

Our new signalling equipment uses digital technologies, which bring a number of benefits such as increased capacity for trains on the network, fewer delays, enhanced safety and lower costs.

In 2019 the Shepperton branch line, controlled by the Feltham Area Signalling Centre, became the first in the UK to use the Atkins ELIX system.

It’s just one example of how signalling is being transformed for passengers, business and freight operators under the rail industry’s Digital Railway programme

What we're doing

To install our new signalling equipment, we first have to conduct enabling works such as installing new cabling and signal posts. We then have to commission that equipment, which requires the railway to be closed to trains.

All of this work is done over a period of months and on different parts of the network. The first phase of work, phase zero, was completed in June 2019 with the commissioning of new signalling equipment between Strawberry Hill and Shepperton.

From 2021 onwards, we are set to commission new signalling in the following areas on the following dates:

Red signal
Red signal
  • Phase two: Virginia Water and Ascot – Easter 2022*
  • Phase three: Windsor and Staines – August 2023
  • Phase four: Feltham and Kew Bridge – August 2023
  • Phase five: Wokingham – March 2024

Line closures

Details of upcoming line closures will be published here.

Level Crossing Closures

We’re going to renew or upgrade signalling equipment for 13 level crossings, which will involve a number of closures.

In 2021, the following level crossings will be closed to traffic for the following dates:

  • London Road, Sunningdale – Saturday 23 – Sunday 31 October
