Thank you all for your replies.
TJ thanks for the pictures. In addition to the forced perspective aspect I too have an Ertl farm equipment dealership. Although 1/64 I think the building works well with O. I've been thinking about getting one of those grain elevators also. Now that I see it next to a flat car I think the shorter silos will be too short next to covered hoppers. Not saying it's definitely out of the question but I will have to rethink it.
