ANOTHER round of rail strikes will affect services on Saturday, Monday, and Saturday, November 19, 21 and 26.

On these days train services on many parts of the GWR network will be disrupted. Trains on the days following the action may also be disrupted.

On Saturday, 19, and Monday, 21, train services operating through the Thames Valley between London Paddington and Bristol will be disrupted. All other areas of the GWR network will continue to operate as normal. Please check your journey.

In the affected areas, where we are able to run services, they are expected to be extremely busy. Online journey planners are being updated with the latest timetable information as soon as is possible.

Customers who have already purchased tickets for strike days can claim a full refund or amend their ticket; those who travel and are delayed may be entitled to delay repay compensation if they are delayed by 15 minutes or more.
