Installing the second mainline flextrack went quickly too. I had seen an s-curve at a local layout and thought it makes for a nice scenic view. I therefore put one in this layout.
Another overall view of the corner opposite the room's entrance. As you can see, I learned the hard way that under-the-layout storage is great, until you stand up straight too early. I covered all exposed benchwork with pipe insulating foam. This doesn't help with a real quick move, but it does prevent the occasional scrape. The foam has a strip of glue which I exposed so that they remained attached to the benchwork.
As mentioned in the layout's design page, I got bored with the around-the-room loop of mainline track. However, in the back of my mind I always thought that I might expand the layout's track plan. I had previously used Micro Engineering turnouts, but I wound up doing so much work on them to get them to function correctly on my DCC layout, that I thought it might take just about as much time to build my own. This photo shows the first two (acceptable) turnouts I built. The GP-7 is on the inside mainline. The two turnouts provide access to spurs on either side of the mainlines.
I put a sheet of foam board loosely on the plywood boards I used by the door, and then used sheets of freezer paper, crumpled up, to do some visualizing of what this mountain range might look like.
Happy with the idea, I cut and installed a sheet of plywood to cover the door's view. Because of the odd angles of the plywood triangles in this corner, I wound up having to use a 1/4" sheet of plywood to allow for some curvature of this sheet. At the top, right, it had to clear the backdrop board installed there. It was a lot of testing and fitting.
I had bought a 135-foot Diamond Scale turntable, so I wanted to use it on the layout. I removed the inside spur track I had laid early, and cut this sheet of plywood, extended the layout benchwork, and cut a hole for the turntable in it.
This view shows how I extended the benchwork supports to accommodate this layout expansion. The turntable area protruded into the room quite a bit, but the plywood surface had to be cut back to the right to allow for access into the room.
