Steel City Traction: The South Side Lines tells the story of the lines that operated southward from downtown Pittsburgh, including routes 35, 36, 37, 38, 39, 40, 42, 44, 47, 48, 49, 50, 51, and 53, the interurbans to Washington and Charleroi, five of the inclines, the experimental Skybus line, and the current light rail system. Over half the DVD is from vintage film footage dating back as far as World War II, showing standard cars as well as the famous PCCs, mostly in color. Modern professional video footage documents the operations of the light rail line. The organization of the program is geographical as well as historical, with many maps showing the development and eventual decline and rebirth of rail transit in Pittsburgh, and a full soundtrack of narration, music, and natural sound.
