A strike called by the train drivers’ union Aslef on Friday, September 1, is expected to cause a two-day shutdown Cotswold Line services.
The walkout on Friday, September 1, will be followed on Saturday, September 2, by another one-day strike by train managers and senior conductors who are members of the RMT union .
Both unions have called on their members to strike in long-running disputes over pay and terms & conditions of employment.
The RMT union, which represents train managers and senior conductors, has also called a strike on Saturday, August 26.
These strikes are expected to cause widespread disruption to GWR services and trains will probably not run on most of the GWR network, including between Oxford, Worcester and Hereford, and between Worcester, Gloucester and Bristol.
