The portion of my layout I'm working on is described under the thread "Layout Planning for SWSM". It is intended to be a highly operational layout and so the reliability of trackwork is critical. The two key aspects of highly reliable track is good alignment and track quality, and good electrical conductivity of all track. I have already have a good start on the laying of track but will back up a bit and show how I've done things so far, and some of the lessons I've learned.
I will try to keep the commercial references to other manufacturers to a minimum. Other than curves, the majority of the track I've laid has been constructed using fixtures and tools from FastTracks. They have made great documentation and videos to show you how to build turnouts, so I'll leave it to you to follow them if you wish.
A couple of areas that I've found lacking is how to actually install, and wire and weather. That's part of what I hope to share in this thread. I'm not saying I'm an expert, or that I do it the best way, but what will follow is what I've found works well so far.
