Work begins at 1:30am on Saturday 11 May and finishes in the early hours of Monday 13 May, therefore trains between London Paddington and Bristol Temple Meads will be diverted via an alternative route and won’t be calling at Bath Spa or Chippenham stations. Rail replacement buses will be in operation and passengers are advised to check before travelling for details of how journeys will be affected.

This signalling work is part of Network Rail’s Railway Upgrade Plan and involves disconnecting, removing and replacing old signalling equipment. Once completed, signalling in the area will be operated from a state-of-the-art digital centre in the Thames Valley, which already covers much of the Great Western Main Line.

Project director Jonathan Davies said: “This signalling work is vital to ensure that the railway in the area is fit for the future and can meet growing demand for train services.

“Passengers will benefit from a more reliable and resilient railway, with fewer delays.

“Thank you to both passengers and the local community for your patience while we deliver this vital upgrade”
