Problems Setting DCC Address For Locomotive

Roy has this question for readers:

“I have an HO steam loco with sound and am having a problem setting a long address. I use NCE Power Cab. I reset the address from 3 to a long address of 5063 and it runs well on that address. I turn the layout off but next time I run the loco in question the address has reverted to 3. I have tried to change it several times on the main but after turning the system off it still reverts to 3. Any suggestions to solve this annoying problem? Thanks in advance.”

    Tough to answer with specific instructions as you don’t say what decoder you are using. It doesn’t matter what DCC system you are using. You probably have a CV that tells the decoder to use long or short address. If you look in the manual for the manufacturer of your decoder (not the one that came with your loco), it can be accessed on line, it will tell you what CV tells the decoder to use either address. You will have to change the number in the CV to tell the decoder to use the long address. It will then only respond to the long address until you change the CV back to its current value or until you reset the entire decoder to its default values.

    Hi Roy
    You should do the following.
    Set CV 17+18 to 0 (zero) and subtract 1 from the value in CV29. CV1 should have a value of 3
    That should allow you to use 4 digit addresses.

    Thanks for suggestions. It is a QSI decoder. I have reset CV 49,50 and 56. No luck

    If using recall loco – make sure that the # of recalls is set to 2. Otherwise recall will only bring up 1 loco – #3

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!
