After it dried overnight, I was looking at the picture of the Middletown track and noticed that the decking is quite close to the outside rail. This makes sense, since there's no reason in building the concrete-lined pit any bigger than needed. It will also look better in the scene.
For most of the frame I need to use two pieces stacked on top of each other for the correct thickness. This also allows me to do the single layer that is needed under the scale house.
I decided I wanted to permanently attach the scale house to the scale track. In addition, all of this is made of different materials, and I wanted to attach the frame and foundation to styrene so I could use styrene cement for a better bond around the unit. So I cut a base from 0.010" styrene. The PC Board is slightly shorter than the craft foam, so this won't really have an impact on the track.
I assembled the rest of the styrene strips onto the base and around the scale track. The scale house is a Blair Line model, built according to the instructions. I considered the Walthers kit, but it has the house with angled corner walls. While some New Haven scale houses were of this type, this one matches the Middletown one better.
I started by painting all of the "concrete" using Tru Color Concrete. I then used the Citadel brown ink, thinned with an alcohol wash I have that already has brown and black inks, plus India ink. It's a very thin wash, though (I use it to dip line poles overnight), and the citadel inks are too concentrated (probably more so since I bought them in the '80s).
Once it's installed I'll need to make the rain guards. I also need to look at where I'll install the sensor for the Boulder Creek Engineering working track scale.
