    @Paul Schmidt Thanks for finding that out. That is a very logical, technical reason. I would never have guessed that was the issue.

    Is this a problem with Peco track , I have never had anything like this with Atlas C55.

    That's a great question. I have not had this issue with ME or Atlas code 55, but then again l don't use Tortoises. (I have nothing against them, but when l have used switch machines it's been the rotary type.)

    I think perhaps if one is trying to assure electrical continuity between the points and their respective closure rails, without having to add jumpers and all the fussy soldering that demands, then maybe this is something you would run into.

    I don’t have a problem with this and I use Atlas Code 55 and Tortoises (for frog power too).

    I wonder if they neglected to remove the springs that slam the points across for positive electrical contact. With the springs removed it shouldn't be a problem. I am quite happy with my PECO turnouts, but have felt no need to power the frogs.

    I've got a couple of Tortoise-operated Pecos where I used the Tortoise's built-in DPDT switch to power the frog. I didn't encounter any electrical issues, either when I installed them or in the 15 years since. But I removed the Peco turnout spring to get the Tortoise to throw them, as the piano wire supplied with the Tortoise was not stiff enough to overcome it.

    Thank You! I really appreciate you going out and getting me a definitive answer to my question

    does a yes anyone remember if there are Model Railroader Magazine issues that have n print the info thatís in the Canadian mountains DCC/DS64 config specs?

    i plan on replicating their control panel routing method, Iím hoping digitrax comes out with a DS64 type stationery decoder that does more than 4 Tortoise switching for routing reasons mostly I could really use an 8 Tortoise switching device controller

    "Ok, hereís the low-down on the Tortoise/Frog Juicer thing, and you can quote me on this to the nscale forum:

    "Peco N scale turnouts have a lot of trouble with maintaining good polarity throughout the points unless you bend the tips for a harder contact with the stock rail. I had all sorts of trouble with this on my New Haven layout, and it proved to be a source of some frustration.

    "The solution is to power not only the frog, but the points as well. In the past, Iíve used Frog Juicers for this with good results.

    "On the Canyons layout, since we were going to use Tortoises anyway, I decided to wire the points to them. The problem is that the throw distance on the N scale Peco is quite small. Without a considerable amount of fiddling, the Tortoise moves the Peco points into position faster than itís own internal switching contacts change. The result is the point contacts the opposite stock rail before the polarity changes on the points and frog, causing the system to short.

    "Weíve disconnected the contacts from the Tortoise and fit Frog Juicers under all the turnouts. Problem solved.

    "This would not have been an issue if we were simply powering the frog, and then wired the points to the matching stock rails, but that would take a lot more time than we had to accomplish the project.

    "So thereís the answer!"

    There may be other solutions, but this worked for them.

    You're welcome. David is a great person, and he and l hired on at MR about a week apart way back in October 2001. We have a lot of common interests in model railroading: we both like N scale, the Soo Line, OO 1:76 scale British railways (he the Great Western and me the LMS), and northeastern railroads (he the New Haven and me the Central Vermont).
