My favourite is the section of the East Coast mainline in Northumberland from Morpeth up to the Scottish border at Berwick upon Tweed, in particular the section looking across to Lindisfarne (Holy Island).
Completely agree! I was lucky to be travelling on this part of the ECML around sunrise last Easter time on route to Edinburgh and it's something else!
