The thin plexi walls presents an interesting idea... it would required laminated detail on the interior as well... And yes, at some point I will be adding some interior details like the elevated platforms, and some sort of representation of inspection pits. I need to put some thought into that. Unlike the original roundhouse, the tracks for this will be fixed to the roadbed, so I'll be able to fool with that stuff down the line somewhat.
As it is, the budget dictates using materials on hand, so it is what it is for now...
