Westbound CTA Blue line train. Chicgo IL. June 2009.

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

A westbound Chicago Transit Authority blue line rapid transit train enroute to Chicago's O'Hare International Airport, passes underneath the Canfield Road expressway overpass bridge at the Chicago city limits near Park Ridge Illinois.

The CTA train, is traveling in the median of the I-90 Kennedy Expressway during the evening rush hour commuting period.
