I used the Zimo MX645 decoder in my goose and now have control of the motor, lights and sound.
This is a 3 watt audio amp, programmable, works on DC and DCC, has features where the sound and lights are on before the engine moves, and for digital users you can drive a servo.
My railbus runs point-to-point over a short distance, so mostly just sits, and I was thinking that the Phoenix card could be a waste in this application. I could just as easily use an ITT “industrial diesel” that just idles with a 9-volt battery for a fraction of the cost and complexity.
But you got me thinking that I can put a time delay relay in the railbus to start the card with a lower voltage before the motor gets power at which time the voltage ramps up to the sound card.
That way we can hear the operator open and close the door, and crank over the engine, before the railcar moves out. (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-cool.gif)
