| Oil Power. Here is a duplicate 35mm color slide of (L to R) Pennsylvania Railroad engine #5755 and another unit whose road number is not recorded. Both are AP-20's built by the American Locomotive Company and rated at 2,000 horsepower each. #5755 was constructed in November of 1947 and retired in September of 1962 after just 15 years of revenue service. Looks to me like it's already being cannibalized for parts! The photographer's name, the exact date, and the location are not recorded. |
