Shorting Out on Peco Code 100 Turnout

Brian has OO gauge and has this question for knowledgeable  readers:

“When joining turnouts running with 12v DC together in a string the locos frequently short out the supply to the track. It would appear to be at the point where one or the other of the loco pick ups crosses a certain part of the turnout. Is this something that can be cured by wiring adjustments?

    If there is a short I would look at how low the wheel wiper contacts are and make sure they aren’t touching the rails as it passes through the points. Very wide wheels may contact both rails at a frog so you might have to extend the insulated area with a little paint on the rail heads. Hope that helps.

  • Don Jenningssays:

    Brian before you tear up a lot of track, Try a different locomotive. If that problem does not show up then it is the first locomotive. Good Luck Don

  • Frank Bsays:

    There are free instruction sheet downloads on the Peco website which give advice on wiring, trouble-shooting and problem solving.


    E.g. “Some locomotives with long rigid wheelbases may experience short circuiting between the open blade and the stock rail. Should this electrical problem occur, the wiring on the underside of turnouts must be modified”

    (Basically this involves cutting links under the track and wiring in a switch to the point motor.)

  • David Stokessays:

    I know we all think we don’t need to read the instructions, but your problem might well be solved by taking Frank’s advice. As K say in Men In Black, read the literature – that includes the very excellent magazines available from your local newsagency, and of course – join the National Model Railroaders Association (NMRA) which has a large library of recommended practice and standards sheets available for members.

Use Tiny Railroad Micro Controllers

A micro controller is basically a small programmable computer device to help the model railroader “make things operate.” It is clever way to realistically replicate the movements, actions and functions you are likely to see on a full size railroad.

It’s YOUR Railroad!

Your rolling stock and locomotives might actually be the center of attention on your layout, but the scenic features that surround and envelop your layout is what's likely to make your train setup stand proud of the rest. Your selection of scenery and structures will add an element of customization that will make your railroad truly unique.

Scenery, structures, and fine detailing is a fundamental aspect of any good model railroad, particularly if it is intended to replicate a true-to-life railroading scene. How realistic or authentic you make your railroad is entirely up to you... and you alone.

Some enthusiasts like to replicate every tiny detail so as to accurately depict, in every aspect, a miniaturized version of a real life scene.

Others in this hobby adopt a more "free-style" approach and choose to mix and match accessories and features they personally prefer. Even though the purist will possibly be unimpressed with unrealistic or out of context elements, it is YOUR railroad layout so you can make it anything you personally want!
