Adding a couple of hand layed upper level loops to the old layout

Now that the test section is complete more or less, I moved on to thinking through how I want to layout the double track upper level loops.  I don't intend to change any lower level trackage.  I have had most of a single track upper level half built for probably 10 years. but never to the stage of running trains.  At first it was going to be 072 tubular then I thought Gargraves.  A while back I got hold of some Tru Scale roadbed from Carey Williams but it was not enough to build what I was after.  I do have a bunch of code 148 steel rail as well, but again not as much as I think I would need and I was really interested in seeing if I could make the Flyer rail work in this application.  So I got some 3/4" plywood sanded on one side and used the truscale roadbed to layout some double track roadbed sections on the plywood.  Inner oval is 48" radius and outer is 52 inch radius per the truScale roadbed.  This puts em on 4" centers.

Here are a bunch of ties laid out on the curved roadbed sections.

Below, I removed the older upper level plywood that had been in place in preperation of setting up the new double loops all the way around.

The straight section here will cross the room entrance and go behind the tinplate station that sits above the lower level terminal tracks.  The intention here is to build a lift out bridge section.

With the old upper level removed, you can see how the new upper level curves will sit above the lower level tracks.  They will actually be more open now than they were before. I'm thinking of building a cut down to the track on that curve and building a girder bridge section to span the lower level tracks.

High angle view, the raw plywood curves are just sitting on my lower level mainlnes.  Too much stuff and not enough organization.

In this shot you can see the elevated section I had built long ago for the old single track version.  Now the plan is to put together something similar but in double track.
