The Electro-Motive Divison of General Motors constructed streamlined diesel locomotives beginning in 1939. Their performance and aesthetic appeal led to the demise of the steam locomotive’s costly burden. Although most railroads in the United States were either gone or in severe financial straits by the 1960s, these locomotives remained in service. They stand as historical relics, pieces of equipment that witnessed the pre-1950s railroad hegemony transition into today’s geographically indistinct rail conglomerates. This is an ongoing project where I am documenting existing F- and E-series locomotives carrying markings of these once powerful and regionally distinct railroads. Affectionately called “Fallen Flags”, these roads crossed the country with over 230,000 track miles, more than double today’s mileage.
