Yes, you can! A product such as the MRC0001665 Sounder Decoder is an add-on to any existing DCC locomotive. It includes the sound decoder and speaker.
I’m looking at the Bachmann (BAC44905) DCC control system and I just wondering if has everything needed to convert to DCC?
Yes, this DCC set includes everything needed to convert your existing Bachmann HO scale set to a DCC ready set. Basically, this set replaces your locomotive, command center, and power supply switching everything to DCC.
