Full report: "This train has been cancelled.This is due to a member of train crew being unavailable. "

As it was a Bank Holiday, I don't expect there would have been very many customers anyway; I can' say that I fancy 07:48 to 18:45 in Swindon when most people are off, nor is the 11 hours the service offers much good for a day out.
