Thanks to everyone for your most generous assistance. So the conclusion I've come to is that the turntable will be on an AR. The track from the turntable to the three-way will be on the same power

Another (seldom mentioned) reason for not having a reversing sections with a lot of tracks (and therefore potentially a lot of locos) is, that an AR unit has its own maximum current, which is usually

ARs operate by detection of short circuits in the track power wiring, which is something I prefer to avoid. A relay connected to the switch machine insures that the polarity is correct for whatever

Thanks Tim, That is an excellent idea. Most of the time it will only be locomotives entering that central section, the classification tracks are on either side of this peninsula. I'm interested in

It really aint? that complicated. The frog has to be isolated, dremel or razor saw. Nothing else is reliable, trouble free, doesn't have to fooled with ever again. I admit I am in O scale. John

You don't need to make the whole yard a reverse section. Put double gaps on all three tracks leading into the 3-way switch at the center. The reversing section would be the three way switch and the

Thanks Don, If I am understanding this correctly, the yard would be on an AR and the turntable would be on another AR? -Michael

I started this thread looking for a good product? that would improve the point contact on turnouts.?It has gone beyond that and become as much about track cleaning products. This is a subject that

Michael, simply isolating and wiring that single straight track section leading to the turntable to be fixed polarity solves the issue. DonV

A little WD-40 trivia: WD stands for water displacement. the inventor(s) tried 40 combinations of ingredients before finding one that worked well. End of trivia, for now. Greg Harter

Dear bob I read his article which basically claims that wd40 contact cleaner and crc contact cleaner and protectant not only cleans the track but leaves a residue which helps conductivity and prevents

Perry, Suspect conductivity of the point rail swivel rivet joint. May need a flexible jumper across this joint to ensure conducive power path to the points. Especially if a loco causes the point rail

Hello Allan, Thank you for your help. The turntable is made by Custom Model Railroads and the wiring diagram indicates that an AR is required. - Michael

Hi Michael, What kind of turntable do you have?? If you have a Walthers, the turntable handles the reversing for you and does not use an auto reverser.? Turntables that use split rings for power

Nat, Do not worry too much about reversing loops. If you want one, it's not as big a deal as some of the discussions had made them out to be. There are few rules, and the wiring is pretty

Hello, I’m looking for advice on how to wire a classification yard. As the photo (Back-to-Back ARs?) in the Photo Folder shows, the mainline passes around the yard to the left. With its’ two
