It almost doesn't look real to me in this shot . . . as though it was a model with a fake background. But it's real - and it's noisy. The "el" or "L" as it's called here, is short for elevated. It's like a subway, but most of it is above ground - hence, elevated. :-) The central business district of Chicago is called the Loop because the L makes a loop around it. This is at the corner of Randolph and Wabash.
