I recently bought an athearn genesis CSX sd70mac and am planning on putting sound in it. What is the best sound decoder for this locomotive?
I'd recommend a Soundtraxx Tsunami (TSU-GN1000 with the EMD 710 sound in it or wait for the SD70ACe decoder to come out as it has the autostart sound in it.) is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
