Several routes of rapid transit elevated trains, all referred to simply as the “L”, loop around a section of Chicago’s downtown, then fan out in different directions throughout the city. The Blue Line ends at O’Hare Airport. The Orange Line ends at Midway. Take a Red Line to Wrigley Field for a Cubs game or down the Dan Ryan Expressway to 35th Street for a Sox game. There’s a Green Line, Purple, Brown, Yellow, and Pink Lines too. The entrance stairway here on Wabash leads to one of the downtown elevated rapid transit “L” platforms where most of these Lines stop. Capturing the graphic lines that caught my eye was a challenge I couldn’t pass up. Love those lines. For sale in “Prints For Sale” above.
