You're welcome! :-) It's a route I've done a few times, and I must say I think the trains are excellent. Not so amazing in the week, but at least they go from A to B without going via the rest of the alphabet in between!!!
georgit79 - Thanks so much, but I'm way the heck out in San Francisco at the moment. I was asking this question for when I fly to London in a few months. :)
