I wonder if it just coincidence that the FGW "meet the manager" sessions which are planned for tomorrow have all been cancelled? Maybe FGW are concerned for the safety of their staff?
More sessions are planned though - I think they could be quite lively..

I'll be going to the one in Cheltenham on the 7th February to ask about the Cheltenham - Westbury services, and then get back here and e-mail the media if I can on any response, as it is Cheltenham where the Melksham trains start/terminate in the week.
Interesting there is no session for Gloucester - are they expecting people to use the train to get to Cheltenham?
