The GNR main line toward Scotland may have made an “end on” junction with the NER main line in that area but some would argue that the West Riding of Yorkshire was the destination of the GN “Main line” which actually got as far North as Keighley, where they had a little used junction with the MR, a company who only eventually built their railway to Carlisle because Parliament forced them to (Shouldn’t play politics with politicians).
Thank heaven for that, or we wouldn’t have the S & C route.
Anyway, Normanton gets my best junction station vote. On the Midland, end of the L&Y’s eastward route and Hudson’s westward route and a fabulous station in it’s heyday.
