Colin Lea, Planning and Performance Director at TfW, said: “This programme of work includes vital infrastructure upgrades for the South Wales Metro and other essential maintenance of our network.

“We understand rail replacements are frustrating for customers and we’ve worked hard to keep service disruption to a minimum.

“We have a comprehensive bus replacement plan to keep people moving while the work is taking place, and we advise customers to check for the latest information using the TfW website or mobile app before travelling.”

Nick Millington, Network Rail Wales and Borders route director, said: “This essential maintenance will help to make the route more robust before we go into the busy summer season.

“We recognise there is never a good time to close the railway, but we have planned the work to minimise disruption as much as possible.

“I would like to thank passengers for their patience and urge them to check their journey before travelling.”
