Engineering work is taking place between Cardiff Central and Bridgend, closing all lines via Pontyclun.
As a result, the 20:45 (departing 20:38) and 21:45 (departing 21:38) London Paddington to Swansea services will be diverted between Cardiff Central and Bridgend (via Barry). They will call at Bridgend and beyond up to 30 minutes later than normal.
