Engineering work is taking place between Bridgend and Cardiff Central, closing some lines early on Monday morning.
As a result, the 05:35 Bridgend to Ebbw Vale Town service will be amended to start from Cardiff Central at 06:05.
An earlier replacement bus will run from Bridgend to Cardiff Central, connecting with the amended train.

These changes are not currently shown in the National Rail Journey Planner, please check back nearer to the time of travel.
