Let me ask this, does the DCC card in my engine EMD GP 40 need to be removed or do I wire the new card into the factory installed part. This is really confusing as I also see sound decoders for sale a little packet no larger then a packet of sugar. Any and all advice is taken in and saved.
Thank you very much

Even some of the experienced people (shops) have no idea as to what board goes in what, I spoke with a reputable shop and was told to purchase the Tsunami TSU-GN1000 and nothing jived when I removed the body or should I say did not look proper. I then called Digi and was told I needed the AT1000 great now I have a board I cannot use. Darn this stuff is like a crap shoot. 7-11

Hello dear friends, This whole sound thing sounds horrifically difficult but hope you can help or send me in a different direction. I have the Bachmann EMD GP40   TSU-AT1000 EMD 645 Turbo   828041   810113 with DCC on Board and I would like to add sound to this engine if it is possible .
Thank you
