Re: Wiring a Helix for DCC

For what it's worth, on my previous layout I had a 4 turn, 2 track helix in HO with a 27 inch radius.  Each turn was split into 2 parts with detection on each part.  I ran the track feeders down the the track bed supports to terminal blocks that connected to current detectors.  This arrangement was absolutely trouble free.  I used 18 gauge wire for all the track feeders from the terminal blocks.  Don't skimp on wire size.
