Train route information!
If you've made your mind that you take a train to Edinburgh take a right side route. There are two train routes in between London and Edinburgh.
I went up to Edinburgh from London(from the famous Kings cross station) and I got back to London from Edinburgh. I took both routes and the right side route was much more scenic, something like window XP wallpaper!
