I stand corrected, Wouter - sort of. In the case you outline, you are correct, Wouter - if we presume that the 1st AR was preconditioned by a previous section that is in the same phase as the short fi

Wouter Not so, because there is no technical reason why, when the second gap is bridged, that the first AR doesn't respond at the same time as the second, which is the same as having the two ARs adjac

Bill It gets tricky to answer this with confidence without a sketch to refer to; in addition, I'm working from my phone and don't have my groups login, so even if you post a sketch, i won't be viewing

BillD When incorporating sections of your loop, you must also ensure that those sections are longer than your longest train. Otherwise the problem just moves. Think you may have done so, but just clar

BillD Think of any single loco as a pair of wires hovering, one over each rail, drooping to touch the rail at each point where a loco's wheels do. In order for a short length between AR sections to do

David, You'll have to post the picture to the photos area here. I saw your post on the Digitrax list. You have two options: 1) The stretch from the crossover to the small 'y' could be fed via an autor

Alan Cut (using Dremel disk or jewelers saw) through the rail(s) at the desired location, fill the new gap with a bit of styrene glued in (I use epoxy, others use ACC), file smooth the rail head if th

Nick Whoops, I just noticed, this is your thread. You may hijack at will! Blair

Nick You've hijacked the thread, this is no longer about MERG Cbus. It's good form to raise your own new topic instead (by hijacking, you've ensured that those who aren't interested in MERG won't see

Greg As I see it, that's a DPDT toggle switch, or a slider, the output from it is used to both control the Tortoise and the track polarity. "SV #1" is probably "SW #1", i.e. switch number 1. Although,

John Two thoughts on this. 1) I have a p2K SW8 that was giving me fits with stop-start issues. Turned out one lead from one truck was broken, so it was running on only one truck's connections on the l

A friend recently purchased a Digitrax DB210 as someone told him he'd need one for his layout. He's trying to figure out how to connect it to his DCC++EX base station. Can he simply use the signals fr

I've built a small detector circuit which detects Railsync on the Loconet cable and, after a programmable delay, energises a relay. That relay turns on my booster at the far end of the basement. A sec

If you intend to use a lot of locomotives with sound, you'll want to use PSX circuit breakers as they're solid state; I have four PM42 boards in operation, and I have to limit the number of locos in t

This actually makes sense. The length of static rail needs to be long enough to give the AR response time. Simple enough at reasonable velocities. Correction noted. Blair

I concur with Allen. As long as - the normal section is truly longer than the longest single electrical entity crossing it (i.e. if you wired all pickups on two locos together to lengthen their electr

Charles Answer - If your booster has a booster common, that's where the PM42 "ground wire" goes; do not 'ground' it. I'm not an NCE user. Someone with knowledge of how to common-reference NCE boosters

If I understand you, Charles, what I'd advise is connecting the reverser at the center of the reversing section, feeding the reverser from the nearby bus feeding the rest of the track. Blair

How about giving us a hint, Steve, as to where you would gap? Similar to my sketch, or differently? Blair

Clarification - the reversing section does not need to include the turnout at E, but must be long enough for your longest train, as does the reversing loop at the bottom, from turnout A to turnout C.
