Upgraded weather warning will bring significant disruption from Monday, GWR warns customers

The Met Office has issued a red weather warning for parts of the country on Monday and Tuesday, with temperatures forecast to reach as high as 40°C in some areas, including London.

Following the warning Network Rail has assessed the impact of the extreme heat on the railway infrastructure and said it would be introducing speed restrictions to ensure the safe running of trains.

As a result, GWR services are expected to be significantly impacted and those trains that do run will be extremely busy. Journeys will take longer and there is a high likelihood of cancellations, delays and last-minute alterations.

Customers are being advised to only travel if absolutely necessary on Monday and Tuesday. Passengers who choose to travel are being advised to check their journeys and ensure they are well-prepared for the extreme conditions – wearing cool clothes, taking handheld fans and ensuring they have plenty of water to drink.

To help customers, GWR is allowing people with tickets for travel on its services on Monday and Tuesday to travel on Wednesday and Thursday instead.

Our Refund and Book with Confidence policies will remain in place. For further information on GWR train services visit:
