Although primarily a Northern English railway, the NER had a short length of line in Scotland, in Roxburghshire, with stations at Carham and Sprouston on the Tweedmouth-Kelso route (making it the only English railway with sole ownership of any line in Scotland), and was a joint owner of the Forth railway bridge and its approach lines. The NER was the only English railway to run trains regularly into Scotland, over the Berwick-Edinburgh main line as well as on the Tweedmouth-Kelso branch.
