I'm modifying this one on the fly. The building will act as a scenic divide to separate the yard from the return loop, which has to be hidden due to the insults I've committed to the reality of the return loop. It is not a rail served industry.
Cleaning up all the flash on the back side of the parts.
Second wall now in and I realise that perhaps I need to add another wall to this building, and that cutting the foundation part off was not such a good idea.
So, here is the other wall, with the foundation piece added back to provide support the wall.
And here is the modified building that shows how the front of the building will hide tracks that cut across the back of the structure. Still a ways to go, but this is enough to serve as it is for the time being.
