Decoder Selector

Here’s how you can be the expert and answer the question, “What decoder is recommended for this locomotive?” Below are three drop-down selection boxes to help you find the decoder(s) you need. Start at the left box and click on the arrow to the right of the box. This will open a list of all the available scales we have in our guide. Click on the appropriate scale. The selected scale will now be the only one showing in this box. Then move one box to the right and select the Engine Brand. Repeat this for Engine Model. When all three have been selected, the appropriate decoder(s) will appear in the Digitrax Product box. We’ve included a button, which will allow you go directly to each decoder's product page.
