Engineering work is taking place between Bridgend and Port Talbot Parkway, and also between Neath and Swansea, closing some lines.

As a result, the 20:15, 21:15 and 22:45 London Paddington to Swansea services will be diverted between Cardiff Central and Port Talbot Parkway, extending journey times.

Additionally, the 21:15 and 22:45 London Paddington to Swansea services will terminate at Neath. Replacement buses will run between Neath and Swansea.
