RAIL strikes will "significantly affect" train services next week.

Industrial action by members of train drivers’ union, Aslef, will significantly affect train services this coming Sunday, February 4 and Monday, February 5.

On Sunday and Monday, many parts of the Great Western Railway network will have no train services, and where trains are able to operate, a reduced timetable will be in place.

The action is part of a rolling programme of strikes by Aslef and is also affecting other train operators this week.

There will be significant disruption to services on strike days, and customers are advised to travel on alternative days. A reduced timetable will operate and many parts of the GWR network will have no service at all. Trains that are running will only be operating for a limited period during the day. 

If you intend to travel on Sunday and Monday, please check before you travel. Trains that are operating will be busier than usual because GWR will not be able to offer the normal service frequency. Other train operators are also affected by strike action, so onward travel could also be affected. 

Where GWR can run services, they are expected to be extremely busy and bus replacement services will not be provided. 

On Tuesday, February 6, there will be some changes to the first services of the day including some planned cancellations. Please check before you travel. 

Limited disruption continues this week which could see some short-notice alterations and cancellations. 

Readers who are travelling until Saturday, February 3, are advised to check both outward and return journeys before travelling. GWR plans to operate a near normal level of service, however, there will be some, limited short-notice changes and cancellations. 

Online journey planners have been updated, please check www.gwr.com/strike for the latest information.

Customers who have bought tickets but do not travel 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.
