Network Rail and Transport for Wales have issued joint information ahead of Storm Ciara, which is expected to bring strong winds and heavy rain to the Wales and Borders route this weekend.
The Met Office has issued a yellow wind warning for the whole of the UK and two yellow rain warnings on Sunday.
Transport for Wales Operations Director Martyn Brennan and Amanda Newton, Senior Incident Officer at Network Rail said:
“With Storm Ciara set to bring gale force winds of up to 90mph on Sunday, Transport for Wales and Network Rail wish to urge all customers to check their journeys prior to travel.
“We’re expecting very stormy conditions, high tides and winds that have the potential to uproot trees and damage infrastructure.
“The safety of our customers and colleagues is our absolute priority and as such there are likely to be a number of speed restrictions in place around our network, while some other lines may be forced to close entirely. We are working closely together to minimise any disruption and will do all we can to keep our customers moving and informed.”
