Even crazier to think there were two stations at Barcombe.
I suppose the thing to remember was that railways weren't really designed with passengers in mind in the early days.
If someone can help me in my ongoing quest to find a picture of an active Hartington Road Halt I'd be grateful. But, alas, none seem to exist
