Changes to train services

Travelling on the Rhymney line April - December 2025?

We’ll be carrying out engineering work as part of the South Wales Metro, with various late evening, weekend, and weekday closures planned during this period.

Check your journey before you travel.

From 24 March, all Caerphilly - Penarth services will run direct between Caerphilly and Cardiff Queen Street as a trial, to help alleviate disruption in the area. If travelling to Lisvane, Llanishen or Heath High Level, please check your journey on the customer information screens.
