Sounds like a cue for the Beach Boys!

Sometimes it is a resonate frequency.  I had a place on the floor of my 
room when I was a kid that would bouce the Bogen/Lenco B-61 turntable 14 
feet away.  You might try an office supply store for a typewriter 
vibration mat.  They might still make them for printers.  These were 
soft but dense quarter inch thick rubber mats that we used under 
electric typewriters years ago.

Leah's got a hyperactive ten year old boy upstairs.  Russian single 
mother.  Not very friendly.

The Midnight Special?  I know it ain't The City Of New Orleans,  
California Clipper, or Orient Express.  Since I hear trains when I visit 
Birmingham, maybe it's Birmingham Bertha.
