There is severe disruption on the rail network in south Wales after heavy rainfall has caused lines to close.
Network Rail said storms and heavy rain mean a number of lines on the network are flooded and have been closed for safety reasons.
It is advising passengers to find alternative travel with rail travel out of Cardiff "unlikely to be an option".
“With wet weather predicted to continue for the rest of today, we strongly advise passengers to expect disruption and look at alternative bus or road options available to them. Rail travel out of Cardiff is unlikely to be an option for many and we do not expect this situation to improve quickly.
“We will continue working round the clock to reopen lines as soon as possible and thank passengers for their patience and understanding.”
Train tracks at places like Llanharan and Skewen have also been flooded, with Transport for Wales confirming there is no service between Pontypridd and Radyr due to flooding.
Network Rail says heavy rain falling on saturated ground is causing issues and that flooding is anticipated in a number of locations.
Transport for Wales has also suspended the service between Newport and Gloucester due to a landslip at Lydney.
