Reply to "Jim Barrett Video on electrical switches for yard spur power?"

Hokie71,

I think the biggest issue with DCS and separately powered yard tracks is something called the watchdog signal.  Apparently, if you apply power to a single track after the rest of the layout is powered up, an engine on that track will not "see" or "hear" the DCS signal.  This means engines on that track will start to run in conventional mode at 18V when you flip the switch, kind of like the old "bat out of h***."

Gunrunnerjohn has developed at least one method to resolve this problem; just search the forum for "watchdog signal."
