In the photo albums, the first photo in “Charles layout design” shows the 3 isolation locations on the peninsula for auto rev. #2. I’ve removed all electricity from this area except the output

Ken, If i am understanding what you wrote I should be OK. Currently my PSX and AR Boards are daisy chained directly from my Command station al all centrally located. From each PSX or AR (only 2)

Your frogs and short circuit protection devices should be located in the wiring between your track detectors and you DCC track power. In this way they do not see the supply current. Not detecting on

Hi Perry, I'm glad to know people are reading my column. Sorry if the September column ruined your day. As far as using the Atlas signal system, I am not an expert on it's use. I just read up on it

I just read Allan's column in MRR sept. I am gald I did. What blow to my plans. Now I have a cunundrum. I have laid all my track. I am using DCC specialties PSX, PSX-AR and Frog -ARs. I also planned

Thanks. -- Dave Portland, OR

Dave, That’s correct, but only if the programming track is isolated from the rest of the layout — which is the answer to the question you asked. Bill D N&W Steam Only

I can buy that John. Don't need to be a victim of Murphys Law. Thank you. -- Dave Portland, OR

Dave, The isolation track is to protect the main track from being powered by the program track, IF the loco being programmed wanders toward the main and shorts across the track boundary insulators.

Hi Bill. But I thought that was the purpose of the auto switch. It senses that you are programming so it de-energizes the main and only programs the program track. If I had 3 locos on the main it

Dave, As I understand it, you don’t need an isolated program track IF the only Loco on your layout is the one you want to program. Without isolation every Loco will be programmed. By isolating

Hi - On this one-line diagram Jim shows the autoswitch wired to a programming track with an isolation track. I understand that the purpose of the isolation track is to keep you from accidentally

Don, Update I now have it working I removed the extra feeders from both side of the loop and now my AIU-01 is showing a LED as On when the train enter the block. All good now Thanks Tom -- Tom

Don Sorry the image disappeared I will place the image in the upload section and post the link The photo is here w4dccqa@groups.io | Album Can you tell me if I have this correct? When I train is in

Tom, the AR controller still needs to be wired from the main DCC bus and all track feeders inside the AR section(s). Each new BD20 needs to monitor all track current to one of the rails Inside the new

Hello All I have a reverse Loop and I setup two blocks in the Loop for signaling All trains can run in either direction thru the loop with now problem. Today on the two feeders I connected my NCE

A final thanks to everyone that has provided feedback. It is much appreciated and at this point I feel I have sufficient information to move forward. Nick

While there are many tracks, if you print out the track plan and look at it carefully, you'll see it comes down to a mainline oval, with a yard connected as a wye at F, with multiple tracks for each
