That, my friends, is the tone I want! (Actually, reminds me a big of Juzzie Smith).
But if someone left my harmonica on the train tracks I think I'd be kind of annoyed. (I wonder though, if you had a full train instead of just a hand cart go over just a cover plate what it would look like?
Edit- maybe not such a good idea. At least one train has been derailed by some kids leaving a brick on the track, and pennies, apparently, can come of the track with a lot of force. No deaths from that, although a bunch of people have been killed by trying to put pennies on the track and not getting out of the way. I wonder if a train company would let you put one under a train that was just starting up...
I just had a weird thought looking at the bell harmonica in the intro to that last video- I wonder if you could hook it to a battery to get it to ring more like a school bell.
I can't think of any practical reason to do it, but I'm still curious.
