Sound Modules

It wont matter without a video


I have been looking around this Train Tech web site and I am very interested in these motion activated self contained coach lights. Looks perfect for Plarail. No wiring from coach to coach, no switches, perfect. In fact, my mind is saying I wonder if just the unit can be used for other applications like activating crossing gates only when a train passes by. Have to browse this site more when time permits. http://www.train-tech.com/index.php/ligh...h-lighting

Funny you should mention the crossing gates thing, I recently came across a capsule scenery piece which is a little train building that has an optical sensor built in which when activated triggers a sound clip. I was wondering if that could be modified to do something else instead, but not really had the time to look into it further yet
