I installed the section of track during the evening when things had cooled down a bit, and it fit fine.
The last major trestle is now complete. It includes a plate girder bridge where the upper track crosses over a lower track/tunnel portal. I hope to have some pics posted in a few days.
I’ve also added some diagonal bracing on a couple older trestles, which I’d been putting off for a long time.
I still have another plate girder bridge to build, for the track which crosses Serenity Canyon behind the “big trestle”. For now though I’ll get by with a piece of 2x4.
At Cora Canyon on the west end of the layout, I need to build a pair of small stone arch bridges.
And on the upper level I have a few feet of track that need minor realignment and ballasting, plus a passing siding that hasn’t been installed.
And now that all the conduits are in place and the track work is nearing completion, I should do something about putting in the rest of the wiring and junction boxes.
