I had a (pardon the expression) choo-choo sound card that fitted in a steam loco tender (namely a Bach 2-8-0) & was activated by a reed switch & magnet on a axel,only a very small pc card with some resistors etc etc on it,no brand name. Someone that thought they needed it more than me,decided not to return it. Anyhow,does anyone know of what I'm on about?A brand name?It only makes a choo choo sound,oh & has a vey small speaker attched to it. I suspect it's a japanese brand/make. I want to buy a few of these,at least 2 for fitting into the cab-forward
I have a car from Aztec that make choo-choo sounds. It is a stock car, has a on/off switch under it and a reed switch over one wheel with a magnet. It runs off watch batteries. It's not very loud and really doesn't sound very real either.
