The building I have built is designed to sit on a level grade. I made the front (track side) taller so the back add on sections were the proper height. Our plan is to bury the front of the building so it still appears to be the correct height. I drew and redrew the plans for this model several times, and found multiple sets of plans and drawings before I was happy with the sizing.
Our Cumbres yards are not to scale, and were designed around the buildings. I am hoping to include the section house, the depot, the snow sheds, a speeder shed, and a few of the various small "tool" sheds around the area. We will not have room to include the trestle here. Our layout is loosely based on the 30's and 40's. This way we can include multiple paint schemes for all our equipment, as well as different structures (like the water tower in Cumbres).
