Due to a shortage of train crew, we expect significant disruption to services on Sunday 10 November. A significantly reduced, amended timetable will be in place for services between London and Bristol Temple Meads and London and South Wales.
Fewer trains will run on these routes, and those that do will be very busy. Services may also be cancelled or delayed at short notice.
Because of the late notice changes, and the complexity of updating timetable systems, journey planners will not show changes correctly before Sunday morning.
We're sorry for the impact this will have on your journey. We advise customers to only travel if absolutely necessary and change plans if possible.
If you have already bought tickets for Sunday 10 November, they will be valid on Saturday 9 or Monday 11 November, or you can claim a full refund.
