Rail disruptions between 9 and 29 June 2025

From Monday 9 – Friday 20 June and on Sunday 29 June, we will be working on track replacements at Filton and Stoke Gifford, as well as completing maintenance on the overhead power lines inside the Severn Tunnel itself. While this work is being completed we’re making the most of the closure of the railway, also carrying out points maintenance and tamping (compacting stone around the track) between Pilning and Severn Beach, and de-vegetation work around the English entrance to the Severn Tunnel.
