| Mann. Here is a photo by an unidentified photographer that was taken near Rockville, Pennsylvania, c. 1966. Shown here (R to L) are Pennsylvania Railroad engine #9766 and another "EF" Class unit whose road number is not recorded. Both were built by GM-EMD and rated at 1,500 horsepower each. #9766 is an EF-15A constructed in January of 1951. In this context, this A-A set is heading toward the Rockville Bridge with a mixed-cargo freight train. (Gift from Brad Mann.) |
