  • David Tuttlesays:

    Can’t tell without more info, with just thus much I would suspect a wiring issue, but cannot be certain.

  • Johnsays:

    What power supply are you using on your layout?

  • Gerrysays:


    You don’t say ‘How’ you’re trying to run your engine i.e. conventional, DCS, TMCC or what, as this makes a difference. Let’s assume you’re simply wanting to run conventional for this discussion. All I can suggest is to check your track has voltage, if not then you need to figure out why it doesn’t. All other future discussions will branch off from there..

    You also don’t say if you’re running two rail (DC) or three rail (AC)…

  • Charles Sealersays:

    Let’s start with what we know: Your Lionel SD-40 works on other layouts. It does not work on your layout. Do you have a volt meter to test track voltage of our layout? Can you have your friends bring their engine over to your track and see if it works? Can you ask them for help?

    Main question: Does your track have voltage?
    Is it clean and free of obstructions?
    Are you using DC or DCC?

  • N. Glennsays:

    Statement: Your loco works, just not on YOUR site, therefore, your site is broken. You need a multimeter to determine if you’re getting voltage to your tracks. If not, check your power source for output. If none, check your input….wiring, fuses (if any), plug-in, and if your outlet is ‘live’! This is basic. If you still have problems, deeper investigation is required.

    Hi Daniel
    I have been repairing lionel trains for over 20 years what do you mean that the engine doesnot work does the engine run or is it just sitting on the track with the lights on does your engine have command control or is it conventional maybe it could be your transformer ,does any other engines run on your layout I need more info to you get back on track.

  • Anthony Germagliottisays:

    HI Daniel,
    One more thing you can try is to make a small loop of track connect up your transformer an see if it runs if it does you have track problems on your layout also do you have lionel tubular track or fast track if it is fast track check to see if their is a bad connection you could also power up your layout and take a bulb with a socket and touch one lead to the center rail and the other to the outside rail if it lights do the the same thing around at different parts of your to make sure you have power around your the whole layout if you do your engine should run if not send me more info and I will try to help you.

  • Ken Dollsays:

    Is you transformer putting out ac voltage or dc voltage the problem seems to be power supply make shure you have voltage at track all around layout check for shorts and on transformer/ controller check that’s hooked properly ac to track is varrible ac to assesorys is constant check for voltage at all connections Ken

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!
