West Wales rail passengers are being urged to plan ahead and check before they travel for the rest of April as infrastructure upgrades take place across the Wales and Borders network.

It has been confirmed that buses will be replacing trains between Carmarthen, Milford Haven and Fishguard Harbour on Saturday 29 and Sunday 30 April.

Jan Chaudhry-Van der Velde, Chief Operations Officer at Transport for Wales, said: “We’d like to thank our customers for their continued patience while the vital transformation work takes place on the Valleys lines and as we continue to work to resolve the issues with our Class 175 trains.

“Our Class 175 trains have been receiving urgent safety checks and engine repairs, after a number of recent incidents.

"This has left us with a temporary shortage of rolling stock across the network and has meant we have had to redistribute rolling stock to affect the minimum number of passengers possible.

“As the rolling stock shortages have eased, we have been able to restore much of our timetabled service.

"However, some services are still being operated by different trains with less capacity than usual, so we’re continuing to work through the repair programme on the Class 175 trains. 

"As soon as each train is repaired and passes the safety checks, it is brought back into passenger service.”

South Wales

Transport for Wales (TfW) will be carrying out infrastructure upgrades across the Core Valley Lines network for the South Wales Metro, resulting in buses replacing rail services on some routes.

North Wales

Elsewhere on the network, engineering work will take place on a number of lines over the weekend of Saturday 22 and Sunday 23 April.

The North Wales Coast Line will be closed between Rhyl and Bangor and the Conwy Valley Line will be closed throughout. Replacement buses will be in operation across these routes.

West Wales

The following weekend, buses will be replacing trains between Carmarthen, Milford Haven and Fishguard Harbour on Saturday 29 and Sunday 30 April.

Current services

TfW is continuing to advise customers that those services which are running will continue to be very busy while their ongoing maintenance programme on the Class 175 trains continues.

The number of trains available for use has increased, allowing TfW to reinstate services on nearly every route across the Wales and Borders network, including the Borderlands Line between Wrexham and Bidston, services between Chester and Liverpool via Runcorn, and the Conwy Valley Line.

However, some services may still be running with reduced capacity, and services between Newport and Crosskeys remain paused.
