SB CTA purple line train. Evanston IL. Aug 2011.

I photographed this digital live sound video one morning recently, in north suburban Evanston Illinois.

We are facing west on Dempster Street near Chicago Avenue. A southbound Chicago Transit Authority Purple line rapid transit train enroute to downtown Chicago Illinois, departs from the Dempster Street station ( Out of view to the right.), and crosses the Dempster Street concrete viaduct in bright early morning sunshine.
