adding sound to already dcc equipped bachman trains. which decoders should i use
Not the decoder that comes on the locomotive. It would be a great help if we were to know what locomotives you wish to convert. BTW, a "train" is a rail unit with motive power and rear marker light(s). A locomotive is "motive power."
