CHICAGO HEAVY RAIL
Tower 12

This image is taken just a few feet away from the previous photo in the series, but the "feel" is very different.  Orange Line trains switch to the left to wind up crossing themselves coming back along Wabash.  Green Line trains continue straight ahead to utilize one half of the Loop on their way out to Harlem/Lake.  The pedestrian overpass ahead is at Adams/Wabash.  Tower 12 controls "L" traffic in this area.
