Planning ahead. Reading and watching. Can I have one bus wire for my spiral helix? 5 levels, outer and inner tracks. Outer loop has sixteen 14 inch curves 16x14" plus 120" of straight =344". Inner loop runs slightly shorter. Rounding up for extra that's 344"x10=3440 or 286+ feet. That's a LOT of wire! The plan was to follow the roadbed and make a channel in the edge so wire can be recessed. Short feeder wires coming from the side.
Using the newest ZW-L. If doable was going to run 4 consists with ABA TMCC at the same time. My hope because of the amount of track and levels they could run with adding Blocks?
Extra effort needed because I'm not hiding the helix.
