My N scale 2'x10' layout has concentric loops and a yard in the
middle. I have a Heljan two stall engine house which opens at both
ends. Since the bldg. is in the middle of the layout and is quite
long, I can use one side as the railroad's engine house at the inside
edge of my yard. The other side of the house is accessible from a
switch on the back side of the inside loop, and passes for heavy
industry. It is designated on my timetable as a car repair facility
in a different town. This gives me an additional industry without
using the space (or capital) for another building.
