Continuing the Rail Truck sound saga, can anyone help me sort out the most suitable Loksound Goose decoder options? Most web sites quote a model number of 72461 but this seems now to be a downloadable sound file on the ESU web site. I'm told by one supplier that this is an obsolete non-supported item and the new version which they supply is 74461. Also, there appear to be two versions of this, an 8 pin and a 21 pin. What's the difference? As a relative newcomer to DCC I haven't met this distinction before. There seem to be other options but I suspect they are blank decoders that need loading with the sound file. I'm assuming I need a minimum 1Amp decoder for the Bachmann Rail Truck. Don (Paladin) has suggested I post this on a "two heads are better than one" basis and thanks ,Don, for your input to date.
Sorry to be late with this response. I have used two Soundtrax TSU750 sound decoders in two of my Bachmann 0-4-0 Gas Mech and they sound very good. They are small but fit ok with some work, they too sound like they are changing gear.
