Travel Advice for South Wales. A joint statement from Transport for Wales & Network Rail.

A red extreme heat warning is currently in place across parts of the Midlands, South Wales and Southern England until 21:00 on Thursday 25 June. In addition, further Amber warnings have been issued for Friday 26 and Saturday 27 June.  

We are advising passengers that are travelling into, through or out of the red warning area on Thursday 25 June to only travel if absolutely necessary. We are also advising passengers to only travel if necessary to, from or within amber warning areas on Friday 26 June.  

Passengers travelling across the rest of the network are advised to check before they travel.  

Temperatures could reach up to 38°C, which is likely to cause significant disruption to train services. Extreme heat can affect tracks, overhead power lines and trains, meaning services may be delayed or cancelled at short notice, or may take longer than usual due to speed restrictions. 

Please check your journey before setting off using our live map, app or website. Allow extra time as journeys may take longer than usual and bring plenty of water to stay hydrated. If you feel unwell, seek help from onboard or station staff. 

Services to coastal destinations are expected to be very busy, with queuing systems in place at key stations. 

If you no longer wish to travel on Thursday 25 June or Friday 26 June, your ticket can be used on any day up to and including Tuesday 30 June 2026. If you choose not to travel, these tickets are eligible for a full refund from the point of purchase. You may also travel earlier than your scheduled travel time on the date of your ticket.  

Please be patient and follow staff guidance whilst travelling with us.
