This section of double super elevated track will be used on the helix, it will loop around the 3rd level and come back down on the other track. I made jumpers without cutting the wire. I striped the insulation and soldered it mid wire. I probably will just drop two sets of feeders instead of doing it that way though.
Nice work! You can also make your own powered unijoiners. https://www.fiferhobby.com/how-to-make-your-own-kato-uni-joiner-power-feeders/
I decided to use WAGO 221s as feeder terminal strips connections to the bus. Nice and compact. Handles 12-24 gauge wire, solid or stranded. Wago has jumpers (could just make one too) and mounting brackets for them also.
