It seems like a similiar problem with Lionel Railsounds. I suspect with DCC the engine needs to be addressed. If it has a decoder an address is programmed. In normal DC ops it may need some bell/ whistle commands. I suggest going to the Spectrum site and reading up.I have found the brand names have good sites with plenty of reference material.
Some members do have Spectrums so maybe they can give more info. This is my limit on the knowledge part.
