Another astoundingly good report, i'm saving part 2 or i wont get anything done today !
Like you i enjoy a good train journey and have done the Scottish trips you refer to. The trip to Wick isnt the most exciting and there are certainly better trips in the U.K you might well prefer. Devon is good and there are some interesting options in Wales. The Settle to Carlisle line is rightfully famous and i enjoyed tacking on a trip around the Cumbrian coast.
I always look out for reports from you, a legend in my eyes.
