Staines to Windsor track renewal

We upgraded the railway between Staines and Windsor, improving reliability for passengers.

Project timeline

Our engineers worked between Saturday 22 and Friday 28 March 2025 to complete a range of projects.

What work is taking place?

During this line closure, we laid 730 metres of new track on the 174 year old Black Potts Railway Bridge which crosses the Thames in West London.

We used 2 tampers, 9 trains and 7 on-track machines to complete these works. This included removing old rails and sleepers from site and installing new track. We also made sure they were tested and safe for travel when the line reopened.

Further along the Staines to Windsor line, our engineers widened the pedestrian walkway over Mays Level Crossing in Datchet.

When the closure expanded to include all lines through Staines, we worked between Staines and Egham at 8 different sites to install new track.

We also carried out structural repairs to the bridge over the River Wey in Addlestone, as well as re-aligning the wheel timbers over the bridge.

When is the work taking place?

Our teams worked around the clock to get this work done.

Our works benefit passengers by allowing trains to continue running safely over the River Thames and Wey into the future, and will help us provide smoother, more reliable journeys through Staines.

Pedestrians will also have more walking space over Mays Level Crossing in Datchet.
