GWR have advised us that: –
“GWR is advising customers to check their journey on Sunday morning before leaving home because of a shortage of train crew.
Scheduled engineering work in Oxfordshire and the Severn Tunnel means more train crew than normal are required to run train services, while sickness and England reaching the final of the Euros likely to reduce the number of colleagues available for overtime shifts.
GWR will implement contingency plans to protect core services and minimise disruption for customers. These are particularly likely to impact frequencies on branch line services and cause short-notice cancellations and alterations, on long-distance services between:
- London Paddington and Bristol
- London Paddington, Swindon and Cheltenham/Gloucester
- Bristol Temple Meads and Exeter/Plymouth
The number of cancellations could lead to a train every two hours on these lines, and other routes may also be affected.
On the impacted routes, where trains are able to run they are expected to be very busy and customers may find it more convenient to travel the day before or after.
To help customers, tickets for Sunday 14 July will be valid on Saturday 13 or Monday 15 July.
Journey planners and other industry systems are expected to be updated on Friday morning with key changes. There are likely to be other short-notice changes through the day on Saturday and customers can keep up-to-date with the latest information at www.gwr.com/check.
If trains are cancelled, customers can use their existing ticket on the previous or the next available service. If you choose not to travel the usual refund arrangements remain in place.
GWR expects to run a full service on Monday 17 June.”
