Hi,I've been considering an expansion on my layout which would roughly be 24*24 feet.I'm considering devoting all or much of the lower level to Cheyenne Yard. Would that be an adequate space to get a decent representation of the yard? What should I concentrate on? The roundhouse is an obvious thing as well as the passenger station since I love passenger stations.But most importantly, is there any maps over the yard. I got one in the book "Sherman Hill" but that shows the yard in the 70's so much would be different. Anyone got any ideas?Thanks,Magnus
