Artist Tristan Hummel has transformed a CTA train into a 400 foot long mobile art show that tours the Loop just once a year. The traveling art show, Art on Track, circles between 4 stops in the Loop – and spectators can come along for the ride. WBEZ's Lizzie Schiffman wandered inside an Orange Line car the morning of this year's show, as artists were busy assembling their displays.
