WOW! Thanks so much for the details. I did this trip many years ago and wasn't sure what I was looking at. I did leave from Paddington Station as I remember. It will be a nice diversion from London for a day. (A day trip on the Eurostar could never tempt me to Paris, that's for sure.)

I have been to the cathedral where Catherine of Aragon is buried; Peterborough, right?

And thanks for the lunch recommendation, StockyClub.
