Remember- Fastrack is ONLY as good as the joints are tight for electrical connectivity.
When you start removing the jumper bars between the outside rails to make the insulated rail sections.
Now, each of the track pins- 3 at each end (6 per track) all must work 100% all the time to not have dead spots. You start saying 10 feet of that- lots and lots of joints..... only takes 1 bad one.
If I was doing this (especially 10 feet worth), I would use 3 wires, and basically create a bus system for each of the 3 rails and each piece of track in this section. Outer, center, and insulated rail section (other outer).
While this picture is a a section, the idea is again, 3 wires, one for each rail connecting across the track joints. Especially on a more permanent install.
