It shouldn't be doing this.

John White
 

I have to apologize cause this is a bit long, but here goes.

So, here is my multi attempt frustration. I just recently purchased a used Proto 2000 GP30 DC locomotive. Nothing wrong with it running. It ran fine. With me converting to DCC a few years ago, I was definitely converting this one. I'm not a newby to converting DC over to DCC. I've got roughly 100 conversions (give or take) to my credit. So it's not like I don't know how to do this. So I converted it and the problems started. I've used Digitrax and NCE basic decoders, so I think that eliminates decoder problems. I soldered the red and black wires to the trucks, as I've done many times before for good contact. The gray to the bottom connection of the motor and the orange to the top. Everything wired like I've done many, many times with no issues. No wires pinched or anything to make it have a problem down the road. I did have to replace two axle gears making sure no contact between the axles. With all that said, here is what I've been dealing with for the last month. Yea, I said month. Mostly to get away from it and the frustration and dive back in.

 

So here is what I'm dealing with. When I run it on my layout from right to left, it wants to stop or at least pause in or out of the curves, but not always. But that is only once in awhile, cause most of the tie it will stop. So, I just touch it as in nugging it very very lightly. I don't hardly even touch it and it resumes running until the next spot it decides to do it again. It did do this four or five times in one complete run. I kept messing, trying to figure it out and with each try, it did get better to the point of only hesitating two or three times but keeps going. I filed, lightly, the frame so the trucks didn't touch the inside of the opening for the trucks. I also added tape on the same area, but it don't seem to have helped. I made some of the changes to the frame tonight with minor improvements. I also put another exact type of drive powered locomotive and it runs very well, with no issues. So I am totally lost as to what could be causing this problem. I'm not stupid, but this one makes me feel that way and I know better. I just can't figure it out. Also, my track is fine as nothing else does this.

 

Think this one over and see if you can help me solve this problem, that shouldn't be this complicated.

Thanks for reading,

JT

Ryan,

I tested Engine Driver to find that I am mistaken. It does not take a response from JMRI to show turnout positions.

Ryan,  

I don’t have a pro cab only a power cab but from my experience with NCE the cab controller only sends commands to the Walters machine. There isn’t any confirmation response to the cab, the cab only remembers the last thing it sent. I believe engine driver through JMRI will receive a response, though I am not 100% sure. 

The machines have multiple feedback options to drive other sets of facia LEDs near your second position or daisy chain the facia controller to a second controller.

Alan,

18 gauge should be fine to operate the Peco motors.  Even 20 would probably be okay.

I am going to be using Cobalt ADS -SX accessory decoders with my Peco twistlok point motors.  What would be the recommended size wire to use in connecting the two units?  My initial thought was either 16 or 18 gauge stranded wire.

Re: Converting from DC to DCC on existing HO scale layout

Hi all and thanks for the responses. Based on this I think that I have a better understanding of the turnout issue and my existing layout. I would never attempt to mix DC with DCC as this was not my intent with this layout.
Best Regards,
Charles Trevey 


Re: Converting from DC to DCC on existing HO scale layout

Don Vollrath
 

Charles, you have good start for a DC to DCC conversion. Code 83 Atlas turnouts do generally have a dead frog with sometimes marginal point rail connections. Barely noticeable unless you run DC trains at slower speeds. But putting in a keep-alive to each loco like as you convert to DCC will easily overcome those issues without making any changes to the turnouts and allow you to run DCC trains at realistic speeds.
Have fun!

Hi Charles,

Your layout sounds like it is in pretty good shape.  If you have some stalling, you may have trouble with sound locomotives.  Upon power interruption, your sound locomotives may cut out and the sound will restart.  A stay alive capacitor will probably take care of that.  This will be easier than trying to modify your turnouts and powering the frogs.

Re: Converting from DC to DCC on existing HO scale layout

Charles, convert a couple of your locos to DCC; buy your DCC system of choice; remove your DC transformer; install your new DCC system and have fun running your trains!
Please don’t attempt to mix the two systems; use one or the other.

Converting from DC to DCC on existing HO scale layout

catrevey@...
 

Hi. As noted above, I am considering converting some of my locomotives to DCC. I have an existing layout where the track is already painted and ballasted and am concerned about whether the turnouts would need to be altered in some way. My track is Atlas code 83 where the turnouts have insulated frogs. The layout runs well on DC with little to no stalling on these insulated frogs. Would the turnout frogs need to be separately powered or would a locomotive decoder with a stay alive capacitor work is this situation? The layout has two rail wiring, with #14 buss wiring and #20 feeder wires spaced every three feet on center. The turnouts are manually thrown. Thanks in advance for any help.
Regards,
Charles  


Re: DCC Specialties PSX-AR

Re- bypassing a circuit breaker...
Remove the 2 wires from the OUTPUT/TRACK side of the breaker and connect them to the power Input wires of the breaker. Be sure to get the polarity correct to avoid problems at other power districts boundaries.

Technobabble- note that the AR unit will almost always power up with the same polarity result, provided no conflict at isolating gaps. This means that the polarity of the AR section will always be the same after each booster power up and match that same entrance end. So you could more easily reverse the AR section wires to demonstrate that the issue now occurs at the opposite end and that the AR section wiring works as expected.

Re: DCC Specialties PSX-AR

Don and to All,

That is the exact problem that I am having. The locomotives travel through the leg of the wye and enter the #6 turnout and set the buzzer off then proceed to the mainline. When then locomotives leave the mainline, travel through the #6 turnout and enter the leg of the wye, it is a seamless transition. Don, how do I bypass the circuit breaker for the mainline that trips and how do I adjust the timing on the AR so it resets in time not to set off the buzzer? I have a VERY hard time reading manuals and then following what they say to do.. I am a watcher and copier person. If I watch you do it, then I can do it.

Re: DCC Specialties PSX-AR

William,
  Check the trip current settings (jumpers).  If different change them to
the same, if same change one to less than the other.  This sounds
like one of the breakers is seeing the boundary crossing as a short
for a bit and then 'getting it right'.
  Have you tested this with a loco with sound?  With a keep alive?
Is the keep alive working correctly (do a quarter test)?

Re: DCC Specialties PSX-AR

Swanny
 

William, you may be seeing a little discussed issue with the timing between DCC Specialties breakers.  Don touched on it, and you'll find mention of it in the PSX-AR manual.  The fix is to program the PSX to delay slightly to allow time for the PSX-AR to properly "reverse" it's polarity.  Done properly, the PSX doesn't see the potential short and shuts down before the AR has a chance to resolve it, which is supposed to happen.  I don't have the docs handy, nor the time to search, but check the AR manual.
Thanks.

Re: DCC Specialties PSX-AR

The power for the AR is coming from the NCE Power Pro Booster directly. The power for the mainline Peco #6 is coming from a DCC Specialties circuit breaker.


Re: DCC Specialties PSX-AR

Paul O <pomilian@...>
 

William, are you feeding the input of the auto reverser from a circuit breaker?
I had a similar problem with that type of connection. Try feeding the auto reverser directly from your DCC power supply.

DCC Specialties PSX-AR

I have hooked this AR in my wye, but I am still having problems. I have insulated both legs of the wye coming out of the wye and leading into (2) Peco #6 Electrofrog turnout back to the main line. on one side the transition is seamless. On the other side when the lead locomotive leaves the leg of the wye and moves across the insulated rail joiners into the #6 turnout the short buzzer on the AR goes off and there is a momentary pause in the consist as the locomotives leave the wye leg and enter the mainline. It only happens one that one side not the other. I am stumped to trouble shoot to solve the problem. 

Any and all help will be appreciated.

Re: Method - was Re: NCE DCC EB1 Circuit Breakers

I have 6 EB1s on my layout with many sound locos and a  lighted passenger train,.  No issues…

Tom/all,

  There is one approach to wiring that works - and all the rest don't
work as well.  It goes like this:

  What you wire today - you test today (or first thing tomorrow morning).

  Seems simple enough - but the important part of it is that you end up
with an "ever growing - Working - railroad".
  Although testing with a meter can work the best method is to actually
run a train (loco) over the newly wired track that you just wired.  For
example testing with a meter probably would have shown your EB1
to be "OK" but running a loco across that joint would have shown
the flipped wires right away.  Yes, there are ways to test with a meter
that find everything ... but my experience is that running a loco is
quicker and more positive.  Plus you get to run trains!

  One of the worst practices is to wire for days, weeks, or months ... and
then test.

  Sometimes scenery work can cause a short.  Usually only temporary
but not always.  Scenery is often far after the track wiring.
                                                                                                      - Jim

P.S. My experience is that the EB1 breakers are fine (work well) ... until
       you start to use sound locos or lighted passenger trains.  I use
       only the PSX breakers for this reason.
