Crossover Problem

Chris asks: “I’ve a problem with my HO Atlas (X) cross over in that I get a stall and will not go through. If I power through it sometimes works and others a hesitation. I’m running straight DC with equipment from the 1960-1970’s except for track (Peco & Atlas).”

    Older stock generally have deeper flanges on the wheels so firstly check the wheel gauge then carefully run a wheel set over the crossover and note if there is a lifting of the wheel as it crosses the frog. If this is the problem then either file the flange down or dig the base of the frog deeper.

    Howdy Chris,

    I also use older 1950 to 1970 engines and some are 0-4-0 which tend to stall out on frogs that are not powered. I found out the hard way on my first layout. I finally went to powered frogs which eliminate the stalls on the crossovers. I use Atlas snap relays hooked up to the switches to power the frogs. I am not a fan of insulated frogs as 0-4-0 switcher engines will always stall on the frogs. All my turnouts (switches) are now Atlas Customline Mark III or Mark IV´s. I have a double crossover on my layout and the frogs are powered using Atlas snap relays.

    Thanks guys for the tip. Found wheels were the problem and am working on the depth so they won’t lift and break contact. When filing down to make it deeper any recommendations on working the sides also, or just leave them as they are?

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!
