Following a change of plans on my part, I now intend making a trip to the Isle of Man instead of Ireland. I enquired today at Didcot (killing time) about the timings for a train/ferry trip from Bristol to Douglas, IOM.
This is the resulting journey plan that was printed off for me.
All looks fine until you check the 'Operating Company' column. Is there a Pendolino ferry I haven't heard about!?!
