Train passengers across Wales are facing widespread disruption on Wednesday as rail operators cancel and delay services amid an unprecedented red weather warning for extreme heat. The Met Office has issued a rare red warning covering much of south Wales from 9am on Wednesday until 9pm on Thursday, with temperatures forecast to climb towards 38C.
Affected Routes and Service Reductions
Rail routes across north, mid and south Wales have been affected. Among the routes impacted are services between Manchester Piccadilly and Cardiff Central, Bridgend and Maesteg, Cardiff Central and Ebbw Vale Town, Shrewsbury and Birmingham International, and Llandudno and Blaenau Ffestiniog. A reduced service is being operated throughout the day for these routes, with multiple trains already cancelled.
Passengers travelling across the Welsh rail network have been urged to check before they travel and allow extra time for journeys. Rail operators have warned that further timetable changes and cancellations remain possible as the heatwave continues.
Met Office Red Warning Details
The Met Office said an "exceptional spell of hot and humid weather" is expected, with temperatures forecast to reach 38C in parts of south-east Wales by 4pm on Thursday. The warning area includes Cardiff, Newport, Swansea, Carmarthenshire, Neath Port Talbot, Bridgend, Caerphilly, Blaenau Gwent, Merthyr Tydfil, Rhondda Cynon Taf, Monmouthshire, Torfaen, Powys and the Vale of Glamorgan.
The Met Office warned that the heatwave is likely to cause significant disruption to daily life and transport infrastructure, with roads and railways particularly vulnerable to the effects of prolonged extreme temperatures. Wednesday is expected to be one of the hottest days ever recorded in parts of Wales, with Cardiff forecast to reach around 35C. Overnight temperatures are also expected to remain unusually high, offering little respite before even hotter conditions arrive on Thursday.
Health Advice and Impacts
The Met Office said the combination of extreme temperatures and high humidity could lead to health impacts, changes to working practices, increased demand on emergency services and further disruption to transport networks. Public Health Wales has advised residents to stay hydrated, try to stay in the shade, keep buildings cool by closing curtains, blinds and windows during the day, and use a sunscreen of SPF 30 and above with at least 4-star UVA protection.
