| Oil Power. Here is a photo by an unidentified photographer that was taken in St. Louis, Missouri, c. 1950. Shown here (L to R) is Pennsylvania Railroad engine #5786 and another unit whose road number is not recorded. Both are BP-20's built by the Baldwin Locomotive Works and rated at 2,000 horsepower each. #5786 was constructed in December of 1948, later regeared and reclassified as a BF-16Z, and retired in September of 1962 after just 14 years of revenue service. |
