Rail passengers across South Wales are being urged to plan ahead, stay hydrated and expect disruption as extreme temperatures hit the region this week.
The Met Office has issued a red extreme heat warning from 9am on Wednesday 24 June until 9pm on Thursday 25 June, covering parts of the Midlands, South Wales and southern England. Forecasters say temperatures could climb as high as 38°C, creating hazardous conditions for rail infrastructure.
Transport for Wales and Network Rail say the heat is likely to cause significant disruption, with tracks, overhead power lines and trains all vulnerable to extreme temperatures. As a result, services may be delayed, cancelled at short notice, or run at reduced speeds, extending journey times.
Passengers are being advised to:
-
Check their journey before travelling using the TfW app, website or live map
-
Allow extra time for delays and queues
-
Carry plenty of water and stay hydrated
-
Seek help from staff if feeling unwell
Services to coastal destinations are expected to be extremely busy, and additional pressure is anticipated in Cardiff on Wednesday due to The Cure’s concert at Blackweir Fields, where queuing systems will be in place at key stations.
For those who decide not to travel, tickets dated for 24 or 25 June will be valid on Friday 26 June instead. Passengers can also travel earlier than planned on these dates. Refunds are available in full from the original point of purchase, provided claims are made before 11:59pm the day before travel.
Both organisations are asking passengers to be patient during what is expected to be one of the hottest periods ever recorded in the UK for June.
“Please follow staff guidance and take extra care while travelling,” the joint statement said.
