DCC Bus reversing question
Thanks for the generic DCC reversing how to, Jim; I'm sure it is well intentioned. Doesn't address my question exactly, but others will benefit. I have to reverse a large area of my layout(up to 16 tr

Block Detection for signalling and automation
Hi Folks When blocking a section of track for signalling and automation, is it necessary to isolate and detect each turnout, or can the turnout be part of the approach block? I can see how it might be

DCC Bus reversing question
That's a good point, Don. Instead of a >10A DPDT to reverse the booster outputs, I could swap the Railsync signal wires. If I dedicate a booster to each yard that would work, if I find a small solid s

Building a yard ladder
I have found the pinwheel style of ladder to be very effective and compact while also being forgiving in clearances. With Peco C100, 7 turnouts give you 84 degrees curvature at the throat of an 8-trac

If using PECO C100, they told me they're designed to give you 2" spacing if laid nose-to-tail. If you want wider spacing, you can easily calculate a length based on the diverging angle(12*) and the de

I have two large staging yards. They are accessed via two parallel tracks that enter an optional crossover - trains can go straight through either side of the crossover, or can cross over. This allows

Twisted bus - diversion into ballast conductivity discussion
Thanks. We use diluted carpenter's yellow, haven't had a problem yet but detection is just arriving on scene - I've been relying on just checking bus-to bus-resistance so far, for the little bit we've

Okay, you're on the right track, but I think you've misinterpreted. If the lights on the DCS don't go out when you short the track, you've not lost your DC input, the DCS is trying to protect itself f

Sorry for the cross mailing. Verify all of these points again: DCS output is wired to the two PSX units, and nothing else. (i.e. no other track segment, etc.) One PSX is wired to one portion of the la
