Re: New DCS52
? ... or if you are like me you use an NCE PowerCab for your "basic/initial programming".
The PowerCab is, quite simply, the best programming environment ... reliable, fast, and easy.? I got one of these beauties back when I was primarily a Digitrax guy (and had a "Zephyr in a box" for programming ... with a PowerPax) and have never looked back. ? There are guys who recommend other programming environments such as the Sprog - I've tried almost all of those and haven't found them any better than my PowerCab.?? ? Additionally, since I'm now running NCE on the layout, I can use the PowerCab on the layout as a ProCab. ? Yes, I have a "PowerCab Programming Track" that is on a dedicated test and programming track (just some track on a board with a PCP attached to the board and the track) that I use for all of my "initial set up of the decoder".? And I have the ability, when wanted, to use JMRI against the layout using Programming On the Main - and use that (POM) for stuff like speed matching, setting sound levels for the actual layout (when needed, not usual), etc. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? - YMMV ...

Re: Seeking reversing section input
Nick, I agree with Tim.? I'd make the upper purple section from the red turnout as far back as your longest anticipated train your reversing section, or longer.? If you are using DCC, I'd recommend a version of the PSX-AR, as well as PSX devices for the rest of your railroad.? You'll find plenty of help on this and other group.io sites directing you to some form of "best practice" or another.?
Enjoy. John? |
Re: DCC system resets when accelerating locomotives
It might be other reasons, but this as happened on our museum layout a number of times, and it has always been too many sound-equipped locomotives and/or lighted cars in the same block. Too much amperage draw which looks to the system like a short. Lighted passenger cars are often overlooked as a sink I agree with Don, try running a train with a single locomotive through the section, stop and then start, then add a locomotive, and another, and so on, yu should reach a maximum that the system can take.

Re: Seeking reversing section input
If you eliminate these connections to the main track
Then your situation will be greatly simplified. Your layout is then a simple oval with the branch line on the tail of a wye to Dubols. Make the branch from Dubols to the turnout on the lower left the reversing section. It's a long reversing section, but there's only one entrance to it (which is good). I would control it with a DPDT relay controlled by the switch machine on that turnout, but you could use an auto-reverser. I would recommend a PSX-AR. Tim Rumph Lancaster, SC |
Re: DCC system resets when accelerating locomotives
Allan and others, an NCE Power CAB can measure and display the ampere demand. It is rated for only 2 amperes. A PowerPRO system (with the right power source/supply) is rated for 5 amps but cannot display the amp demand. Which system is being used? Monitor the voltage from the power supply. Is it also dropping out or is it only the internal booster?
Look also for other clues. Does it occur with the same or group of same loco(s)? Does it occur near the same Section of track? Look for an internal wiring short due to something in the loco touching the frame due to flexing or a loco to loco short through metal couplers as they bump one another. If it is only happening with a multi unit consist, try removing the locos one at a time. Does it occur when pulling no cars? DonV |
Seeking reversing section input
Hi, I'm re-starting my RR from scratch (getting more space is wonderful).? I've found reversing sections aren't my strong suit, so I'm seeking feedback on the plan to see if I have it right - or too much, or too little, or missing something else altogether.? Please refer to the RED section of this link?/g/w4dccqa/files/ReverseLoops/New%20RR%20Design.pdf
Ignore the tracks that appear to overlap, there are height differences that may not be apparent unless you have outstanding eyesight (or a magnifying glass).? Thank you in advance for any insight you can provide! Nick |

Re: DCC system resets when accelerating locomotives
Phil,
? The PowerCab is seeing a short/high amp draw - there's enough power for the layout to come up but not enough for the added draw of trying to move a loco.? Sound locos draw more than non-sound.? Did you add more locos?sitting on the track?? Even one more than you used to use can cause a problem.? ? Take everything off the track (including cars), test one loco at a?time to see if it is one of your locos - no?? Now start adding additional locos one at a time to see if it just too many at once.? Start adding cars back - say 3?or 4 at a time - still no? ? Look for a tool laying on the track just out of sight - such as a screw driver or pair of pliers. ? If you've made any recent track changes - look there.? If you've done any recent scenery work look for possible shorts caused by same. ?

DCC system resets when accelerating locomotives
Phil T.
On my NCE DCC Power Cab layout, after over 10 years of successful operation, my DCC locomotives began to reset the system after I had accelerated above 3 or 4 on the 28 speed setting. By reset, I mean that the system turned off and then went through its starting cycle. Using my multi meter I looked for residence and found heavy resistance in one rail leading to a turnout. I suspect it must be the problem, but I don't know what to do about it. Should I make new wiring connections there? Should I get a new turnout? What is the best way to handle resisitance? Additional info: My layout is small. It's the Yule Central from the Small Railroads You Can Build, edited by Bob Hayden in 1983. It's an oval on a 4 x 6 foot table with two spurs, a tiny run around track, and a small two track stub yard. There are six Atlas snap turnouts and four DPDT switches for block control. I coverted to DCC around 2010 by upgrading wiring. I installed a 14 gauge bus line and attached the 22 gauge feeders with solder and suitcase connectors. I sent my PowerCab into NCE and they tested it and found that it was working perfectly (I have the 1.28C Chip). They suggested I test my decoders and wiring, and perhaps consider purchasing a Smart Booster. Further testing my PowerCab system on an EZ Track oval showed my decoders and PowerCab were working fine. Some of my decoders required resets to factory defaults. I tested my wiring for short circuits using the "quarter test," and each time the quarter was laid on both rails my system turned off. |
MERG (Model Electronic Railway Group)
Several posts on this forum have referred to MERG CBUS as a layout control protocol (perhaps most popular in the UK where MERG is headquartered), and several people have referred to the many electronics kits made available by MERG. ?I joined MERG about a year ago (it is a hobby organization with about 4000 members) and have much enjoyed participating in their Zoom meetings as well as reading their quarterly journal and ¡°knowledgebase.¡± ?They have said that Zoom meetings will continue indefinitely as it has boosted their geographic reach and made it a more worldwide organization. ?DCC of course is core to many discussions. ?Just passing this on in case others may also find this group of value. ?See?

Re: Digitrax Throttles not working
Your problem sounded familiar as soon as you said, "My Club." if you have someone who uses their own throttle it probably wasn't attached to the layout and was not affected by a software change and should work.?When you turn on Digitrax, it beeps a code that tells you the systems status. The codes are in your command station manual, there are a bunch. Have you reprogrammed your command station and boosters. They can only store so much information. When you start up, use one throttle and one engine (preferably a lighted, sound, engine), turn on the power, if the engine doesn't operate, touch Pwr,? +,? Pwr and try again. Don't program on your layout, If you have folks that program with their throttle, move them to an isolated command station on a test track. When a throttle speaks, EVERYTHING on the layout listens. If you have a short, the equipment will shut down and restart until the short clears and the ticking sound it makes is very subtle. If there is any noise, you wont hear the very light ticking.?Parking on switches and across gaps are a common cause. You can roll across gaps and switches for a thousand years and everything is fine, park on one and you can have a short. Consider using Electronic Circuit Breakers or Digitrax PM42s to separate power districts.? I am guessing that you have already discovered the problem or it vanished. It didn't vanish, someone unknowingly fixed it. We go for months, even do OP Sessions without a hitch in our Getty-Up and suddenly humanity is teetering on the edge of DCC heck. It almost always turns out to me something simple.? An alternative solution is to brew a pot of coffee and arm-chair for a time, that is fun too. I hope you have as much fun as i do. jd
