I like the idea, but I think a sound board triggered by ______ (something) with addressable loops would be the best approach! Not too hard for a single sound loop located on the side of the track, and triggered by isolated rail.
Anything more than that, and it's probably "Arduino time"! One of these days, I would love to try something like that...I've done a lot of programming in my days, but haven't got the nuances of the Arduino down yet! (But I keep playing with 'em)
