Okay, I give up. I googled and wikied and the only things that looked like they might be able to give me the answer were images too freakin' small to read the text.
So on a locomotive, a passenger car on a turn-of-the-century era train, what's the parts of the wheels that make the infamous clackity-clack sound? I'm assuming it's the bar between them, but is that called anything in particular? And if it's something else, what is it? I think what I'm looking for is
"brake beam", but I'm not sure. ANSWERED! Thank you!
(And for a bonus - does anyone know what the sound would be like from inside of such a car, either from personal experience or from background noise in movies? I'm deaf, so that makes it a little hard for me to figure out the answer directly.)
Damn fussy characters. -_-
