Great Western Railway has joined South West Trains in warning would-be train users of the upcoming disruption.

Industrial action will affect rail services this coming Saturday and also on Friday September 1 and Saturday the 2nd.

GWR says it, along with other train operators will be running a revised timetable and you should check your journey before setting out.

 The company adds; " If you've already purchased a ticket on a strike day, you can claim a full refund or change the date and time of your ticket. "
