Well, I've sat and looked at the various holes on my small pike and would try fitting existing structures here and there with limited success. So a scan through the online pic of kits was in order.. Well, I'm going to have to spend some money on this one..
I love the timber craftsman kits but this area in question is the rear side of the city, so 99% brick and concrete/cement. I have some Monster Model Works laser sheeting but I'd need to spend a lot more than I can for the size of the structures I need to justify even one box car against it.

About ten years ago, I built a bunch of DPM kits but left the unseen half untouched, using MDF for the backwalls. Since then, I've found that these structures as they stand don't fit. So I had to remember what paints I used on the initially completed portions and apply these to the fresh ones. This, folks isn't as easy as it sounds. Ten years is a long time in modelling and paints change or don't even exist.
