Started laying out the O27 loop in the center. Also put together the other two bridges for the layout. I'm going to have the far straightaway of the O27 work a slight incline so I can feature the short extension bridge in the middle. If I have time, and it's warm enough in the workshop, I'm going to make new bases for the two girder bridges I have. They're for O27 track and the FasTrack doesn't fit. I have a bunch of aluminum flashing from a project way back. I just need to roll it out, cut it to fit, and hammer it flat and it should work just fine.
Once that's done, it'll be time to start figuring out where my buildings and accessories will go, and then time to truly wire the track up.
