The layout is progressing well-I think we might call it Clifton and Lowther Junction, we have traffic from the North East via Kirby Stephen (East) so we have weight issues via Belah, we have trains from Cockermouth and Keswick , and we seem to have traffic from Warcop to Longtown, and some main line movement toward Penrith -I am throwing the floor open to suggestions for interesting and appropriate consists: gunpowder? Haemetite? mixed trains? excursions?
Locos: Union Mills G2, Minitrix Ivatt 3mt, Union Mills Cauliflower,Minitrix 9f (2), Minitrix Brit,Union Mills D20, Pug.Lots of blood and custard, lots of weathered grafar vans.
Suggestions on a postcard-and I will put some pics up.

Couldn't find a postcard but have you thought about doing a milk train, that's the limit of my sugestions today. 

Though I'm curious about your layout being as you've got it set near my neck of the woods.
