Been a while since I posted, so here's an update. All of the girder rail in the city area is down, but there have been some issues with the underlayment material the guys used in portions of the area. The material won't hold spikes so we need to do some retrofit. On the plus side, the "main line" including the other reverse loop is now all in, including the tracks for the car house and small yard.
The club guys would like to extend the auto reverse run over essentially the full length of the run, but that means I will have to take the Dremel to several of the Orr single-point turnouts to gap them for two-rail. I've been reluctant to do that, but wondered if any of you had done this and what pitfalls I might encounter.
