Westbound CTA Blue line train. Chicago IL. June 2009

I photographed this digital live sound video after work one evening, back in June of 2009.

We are looking east from on top of the North Canfield Road overpass bridge, near the Chicago city limits border close to Park Ridge Illinois.

It is the very busy evening rush hour on the Illinois U.S Route I 90 Kennedy Expressway, and the eastbound traffic is moving at a crawl.

A westbound Chicago Transit Authority Blue line train enroute to Chicago's O'hare International Airport in nearby northwest suburban Rosemont Illinois, moves quickly along to the next station stop at River Road.
