I have a Bachmann Spectrum C40-8W DCC equipped without sound. What is involved in adding sound to this locomotive. What can I expect to pay?
The last entry under 'Bachmann Spectrum Diesels' in the Soundtrax decoder selection shows the various decoders and speaker needed to install sound in your locomotive. You can get the pricing info by clicking on the link for each of the decoders listed.
