It was on the local BBC news today that the train due to run this service will not be ready until September as work to update to latest safety regs is behind schedule. Does someone in the know what's caused these delays? What is the planned train being used - I guess some kind of DMU? Surely SWR could have a quiet word with GWR and maybe get a cascaded 165 on loan for the summer. Seems a lost opportunity to miss out on the summer season.
