What's Happened?
We have been made aware of a signalling problem between Swansea and Llanelli.
As a result, fewer trains will be able to run through the area until the signalling system is working normally.
Our colleagues at Network Rail are aware of the problem and technicians are currently en route to the affected signalling.
We will publish more information here, once we have received an update from the infrastructure technicians.
Please check back shortly. We apologise for the disruption caused to your journey.
