Transport for Wales (TfW) is urging rail passengers to check before they travel for the rest of April as infrastructure upgrades take place across the Wales and Borders network.

South 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.

Buses are replacing trains between:

• Cardiff Queen Street and Cardiff Bay from Saturday 15 April to 12:30 on Sunday 30 April
• Pontypridd and Aberdare from Sunday 16 April to Friday 12 May
• Cardiff Central and Radyr via the City Line from Monday 17 April to Friday 21 April, and from Monday 24 April to Tuesday 2 May
• Cardiff Central and Radyr via Cathays from Tuesday 25 April to Tuesday 2 May
• Radyr and Pontypridd from Tuesday 25 April to Friday 12 May
• Pontypridd and Merthyr Tydfil from Saturday 29 April to Tuesday 2 May
• Pontypridd and Treherbert from Saturday 29 April to early 2024
• Services between Cardiff and Ebbw Vale will be replaced by buses on Sunday 23 and Sunday 30 April.

North Wales

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 the weekend. Replacement buses will be in operation across these routes.

West Wales

Buses will replace trains between Carmarthen, Milford Haven and Fishguard Harbour on Saturday 29 and Sunday 30 April.

Current services

TfW is advising passengers that those services which are running will be very busy while the 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.

Some services may run with reduced capacity, but services between Newport and Crosskeys remain paused.

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.”
