It is intentional, because it was a light railway. But one of those arguments that I can never quite resolve for myself given the later take-over. Even it was just Reedness Junction it would have appeared.Is it intentional that the Axholme Railway is omitted ? Although initially built as a (longish) light railway, it was taken over jointly by L&YR and NER, and ran passenger services until 1933, crossing into Lincolnshire near Thorne South.
Great map; wish I had the time (and ability/patience) to try something similar for Lancashire
Edit: Actually it'll be the whole of that branch as Fockerby is Yorkshire although the two stations before it are Lincolnshire (although Eastoft is a 50-50 split between counties, I read!).
No - that's another light railway.
As I say it's something that I'll probably keep coming back to, but for now they're excluded - see the Notes section on the map.
Further edit having slept on it: assuming I can work out how to do the fiddly boundary for the Axholme Joint's Fockerby branch, and shuffle the station labels around to make space for the Derwent Valley, there might well be a Second Edition later in the year. If I can find a timetable on Timetable World with Nidd Valley Light Railway services that will get added as well. No promises
