Thanks for the explanation Eric, I wasn't quite sure myself as I'm too young to know for sure, but I'm actually in the process of building an N gauge model of Inveresk station and jsut trying to understand my stock requirements.
I did have a previous layout that was based on waverley route stock, primarily from the Edinburgh end but I also decided to add in a good few Kingmoor entries including two Brits. Like you I'll probably just run them to be honest, but I'll need to see.
Thanks again for the explanation
