Customer Advice
-
Amended service to run during extreme heat following rare Met Office red weather warning.
-
Essential travel only on Wednesday 24 and Thursday 25 June into, through, or out of the red warning area.
-
Due to a rare red warning of extreme heat, customers are being warned of essential travel only on Wednesday and Thursday.
-
Extreme heat can cause rails to expand and buckle, so when temperatures reach certain thresholds, trains must run more slowly to keep services safe. This will mean fewer trains and slightly longer journey times during the warmest periods of each day.
-
Prolonged high temperatures can also affect equipment on our older regional train fleet, including engines and cooling systems. This means there may be some short-notice changes or cancellations, particularly during the hottest parts of the day.

To help customers, those with tickets to travel on Tuesday 23, Wednesday 24 and Thursday 25 June can use them to travel on Monday 22, Tuesday 23 and up to and including Friday 26 June. The ticket changes apply to those travelling into, through, or out of the red warning zone local journeys in Devon and Cornwall do not apply.

While we expect to operate the majority of services across the network, the reduction follows the Met Office extreme heat weather warning from Monday 22 June until Thursday 25 June.
