Re: Dual Mode? DCC/DC

Greg Harter

Just for info:  Our club, in Columbus, Indiana, is over 25 years old, and has been running both DC and DCC on the same layout for over 20 years.  We use DCC detector boards, which we designed and built, that preclude a loco going from a DC track to a DCC track, or vice versa.  We have four mainlines, several crossovers and a couple of reversing loops, If the current on two specific mainlines isn't the same (DC or DCC), the crossovers will not operate, and/or the isolated track section between those two mainlines will not receive any current of either type.  We have never had an incident where this did not work, and have not had an incident involved any damage to a loco.  

We planned this originally because we had several members who wanted to run DC and several who wanted to run DCC.  

We did a clinic at the 2016 NMRA in Indianapolis on how this operates.  

Dual mode decoders are okay, but very limited.
