This was a result of trying to find a suitable building for a triangular site on my layout formed by a main road, side street and a siding. Checking through my kit stock and doing a net search, the Walthers Grocery Distributor seemed to be about the right size and could be fiddled with using a cut here and there. I came up an arrangement I was happy with. Then it was time to cut some walls, one thing led to another and here is the result. My take on a Smart and Final Wholesale Grocery of the 1950s (an actual company with a long Californian history).

I'm beginning to make some structures for my layout and finding many of my kits have poor model roofs. Feeling that roofs are so visible and thus important, I intend to replace with sealed seam metal roof and asphalt roof sheets from Evergreen, Micromark, respectively.

Question though: How do you experienced modelers solve for the roofcaps necessary on these roofs, how do you fabricate the roofcaps and what strip styrene do you use? (I'm modeling in styrene, not wood).

For my On30 roundhouse I'm trying to add details that would have been common in the 1920's.  I've been able to visit roundhouses in Baltimore (Ma & Pa) and Savannah (Central of Georgia Railway) but most of my inspiration has come from internet searches.  The Savannah roundhouse had wood block floors and rectangular smoke jacks that I copied.  The Baltimore roundhouse had wooden truss framing that I used in my modified Thomas Yorke model.  I added inspection pits based on Central Pacific RR drawings.  I also added a drop pit with a hydraulic lift
