|Slope to Works. Here is an original photo that I took of a Pennsylvania Railroad train between SLOPE and WORKS Towers in Altoona, Pennsylvania, on 06 June 1965. Shown here (R to L) is PRR engine #5865 and two other units whose numbers are not visible. All were built by EMD. #5865 is an EP-20 built in 1948 and rated at 2,000 horsepower. They are pulling an eastbound passenger train, and will soon stop at the Altoona Passenger Station on their way to Philadelphia and New York City.
