And thinking of places not in Scotland - you've got that line over to
Aberystwyth - a good 2 hours or so from Birmingham.

I've done 7 day Rail Rovers in the past, and have ticked off most of the
'InterCity' routes, but made relatively little impression on the branches.
And by the end of each week I was totally fatigued - travelling being
somewhat draining even when you just sit in First Class for a few hours
being fed tea and cake.

You can always plan sleeps so you're on a long distance train. That'd be
one way of doing things....
