| Oil Power. Here is a duplicate 35mm color slide by an unidentified photographer that was taken near Duncannon, Pennsylvania, on 6 August 1962. Prominent here (R to L) is Pennsylvania Railroad engine #9490 and another unit whose road number is not recorded. Both were built by Fairbanks-Morse and rated at 2,000 horsepower each. #9490 is an FF-20 constructed in October of 1948 and retired in December of 1963 after just 17 years of revenue service.
