HI Chris ,I don't have any plans but I might be able to find some pics . I have a route in Anglia somewhere and its a junction somewhat like Melton Constable with a small running shed and turntable but to make it look good it needs some added things ,you know what I mean. George
Find what you can, I really need at least some prototype information to work from to make good assets. I have a great source of GE prototype photos, plans and data but I don't have the complete set at the moment (complicated situation) but should have by the new year.
Anyway, if you want, PM or email me any information you find and I'll see what I can come up with, but no promises on timescales .
