Not every picture is worth a thousand words. Some are worth 20, 25, 30–the length of the caption that lets you know what you’re looking at. After months of dour warnings, the CTA shifted from four tracks to three on its north-south corridor between Addison and Armitage. The Tribune sent its photographers out to capture the suffering commuters, and posted their results online: an eight-picture essay titled “CTA Woes.” The problem is that what they were shooting was almost unshootable. Nobody looks happy waiting for an el train in the best of times. A line is a line. A two-bus convoy is a two-bus convoy, even if the caption, “Buses stack up on Marine Drive north of Irving Park in Chicago on Monday, the first day of major construction to the Brown and Red Lines,” tries hard to stir up a sense of barely endurable trauma.
