Two further days of rail strikes will take place (February 1) and Friday (February 3), and GWR is reminding those looking to travel to check their journey beforehand.

The Aslef union, which represents train drivers, is taking action that will affect rail services on the two strike days, and a revised timetable will operate across several train operators, including GWR.

On strike days only a reduced service will operate on a limited number of routes.

Many parts of the GWR network will have no service at all.

A limited service, starting later and finishing earlier (between 7.30am and approximately 7.30pm), will run only on routes between Plymouth and Gunnislake, Penzance and St Ives.

Unlike previous strikes, the days between strike days and immediately after the last strike day will be largely unaffected and GWR expects to be able to operate a full level of service, with some very minor alterations.

Online journey planners have been updated with the latest timetable information.

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

To help customers, tickets will be valid for travel on alternative days on GWR services: tickets for February 1 and 3 can be used the day before, or up to and including Tuesday, February 7.
