How to a Wire K-Line Crossing Gate

Charles asks readers:

“I forgot how to wire my crossing gate. It has two bolts with nuts in front of the gate. K-line made it. Everything I try it only does two things.

1. It goes without a train going pass.
2. It doesn’t go down at all.

I even tried to insulate the track outer rail as well as the center rail. Still did the same two things. I lost the paper on them how to wire them when we moved three years ago. Please can I get some help on wiring the O gauge crossing gates – thank you.”

    One lead goes to your AC accessory source (10-14VAC). The other goes to an insulated outside rail. When the three-rail equipment rolls into the insulated rail section, it completes the circuit to common and the gate comes down. If you’re using FasTrack, you can remove the cross-plates from the bottom of the track section and remove the track pins from one of the outside rails to create an insulated section. Atlas 3-rail track is already insulated; just use insulated joiners for the section. MTH ScaleTrax is also insulated so you just have to cut breaks in one of the outside rails. Lionel/K-Line tubular track just requires removal of one of the rails and wrapping the mounting area with electrical tape to keep the ties from contacting the rail, then use insulating pins.

    Another way is to use an infra-red optical sensor to connect the signal to common. You’d connect the wire to the “normally open” side. When the train passes the sensor, it completes the circuit and lowers the gate.

    Hope this helps.

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!
