| Turbine. Here is a photo by William B. Beamer that was taken at the Horseshoe Curve near Altoona, Pennsylvania, c. 1944. It was published originally in David R. Sweetland's (2000) book entitled "Pennsylvania Railroad Color Pictorial: Volume One ~ Altoona To New York City," page 26. Shown here is PRR engine #6200, the S-2 (6-8-6) "Steam Turbine" built by the Baldwin Locomotive Works during September of 1944, rated at 6,900 horsepower, and retired in January of 1952 after barely eight years of experimental service. |
