A Singing Subway

I don't know why I hear it or if I'm just loosing my mind but sometimes... I can hear public transportation making music.

When I stepped out of my car this afternoon, I focused on the hum of the 18 wheelers behind me. The highway wails at me even through my window as I sit at this desk. Yesterday the subway rails sounded like a woman singing a sad note. These things catch my attention and stick out.

Remember in the Broadway play Wicked when Elphaba, (the wicked witch of the west) realizes she can make the broom fly? The broom didn't sing of course but the ladies sang and Galinda sings, "you're having delusions of grandiure".

But Elphaba wasn't. She rode away on her broom and the music got louder.
