SoundTraxx Decoder Selector

Welcome to the SoundTraxx Decoder Selector! This section will assist you in locating the correct decoder and bill of materials for installing a SoundTraxx digital sound decoder in your locomotive. Simply click on the scale of your locomotive, then the manufacturer of your locomotive and finally your specific model. Please note, those models with the initials NA listed under the speaker/ baffle column come with a speaker and baffle factory installed therefore these are Not Applicable. Those models that have not available listed under the speaker/ baffle column require a speaker or baffle that SoundTraxx doesn’t currently offer.
