Engineering work is taking place between Cardiff Central and Radyr, closing all lines via Fairwater late on Wednesday and Thursday evenings.
As a result, the 22:52 Aberdare to Cardiff Central service will be diverted after Radyr to run via Cardiff Queen Street, and will not call at stations via Fairwater.
A replacement bus will run between Radyr and Cardiff Central via Fairwater.
