Thanks Don.? And thank you all for your comments.

Don V shares: "Mike, placing a snubber at/on the track end of a current based occupancy detector is problematic. So I would say no. It is not really a sub buss unless you run both wires as a pair

How all. What causes a short at the gaps from crossing over from one to the other district . You see the train stop on the gap with arking on the wheels at the gap. Till the booster resets till the

Mike, placing a snubber at/on the track end of a current based occupancy detector is problematic. So I would say no. It is not really a sub buss unless you run both wires as a pair all the way out to

Any DCC signal bus 30 or more feet long is likely to operate erratically if it doesn't have a snubber. YMMV, but good practice is to add the snubber. Don W

I'm planning on using a single wire sub bus for signalling and block detection purposes consisting of 12 AWG stranded wire.? The blocks will be from 18' to 30' and fed by either 10 awg or 12 awg main

Allen, I should have done more testing. It wasn't the MTH. I have a 6 stall roundhouse. It's powered with a "vampire" terminal strip. I disconnected the power to the strip and the ACM started working.

Greg, In this digital age, I know that some of the switches I have used in the past are no longer commonly available.? I did find what I was looking for on eBay. I have seen industrial switches in

Thanks--but this pushbutton only has one set of contacts. ?I need one set for the LED and one set for the twin coil.

Greg, I have used the following lighted push buttons from E-switch. I purchased mine from Mouser but I don’t see them listed anymore. Looks like they can be purchased directly from E-switch in a

Remember GE's ASTRAC? ?That's how long I've been in (generic) multiple train control. ?1972! ?I have a DCC layout that was started before Tortoises were available, and before turnout friendly items

Make sure there is a booster common connection between the two boosters. Wire the PSX-AR directly between one of the boosters and the track. DonV

Cliff, I'm glad you found the problem. I'll have to try a MTH locomotive and see what it does to the track signal.? I've got a couple packed away.? I've got a lot on my plate at the moment.? It

Don, The PSX-AR is a combination electronic circuit breaker and a automatic reverse section controller.? It should be placed between booster and the track to be reversed.? Do not place it before or

I’m installing a PSX-AR board for a reversing section on my layout. ?The reversing section is located between two different buss power districts (DCC). ?At the moment I’m only planning on using

Can I use commercial 1-to-1 connectors between Atlas signal boards? ?RJ45 and RJ12, etc. RicZ

Allen, You had an excellent idea of disconnecting the track. It worked. I reconnected the track and it failed. So I started looking at engines on the track and decided it was the MTH diesel. It's off

Hi Cliff, Since it worked sometimes and you have worked over the RJ phone cords, I'd look at the DCC signal coming into the ACM.? Since you probably don't have a scope to look at signal integrity,

Allen, Thanks for responding. Everything worked perfectly with the blue box that came with the turntable (except the electric eye). But the unit has never failed. The ACM did not for about four tries

There are about a dozen different features of the ACM that you can use.? Since you mention my article, I will assume that you are trying to set up DCC control of your turntable. Since you mention
