Engineering work is taking place overnight between Cardiff Central and Bridgend via Pontyclun, closing some lines.

As a result the following amendments will apply:

• The 22:30 Swansea to Cardiff Central service will be diverted via Barry.
• The 23:15 Cardiff Central to Carmarthen service will be diverted via Barry. A rail replacement bus service will run between Cardiff Central and Bridged via Pontyclun.
