DP-Prints. Here is a print by Martin S. Zak that was taken near Perdix, Pennsylvania, c. 1966. Shown here (L to R) is Pennsylvania Railroad engine #5840 and two more units whose road numbers are not recorded. All were built by GM-EMD. #5840 is an EP-20 built in August of 1947 and rated at 2,000 horsepower. In this context, this A-A-A set is pulling a passenger train out of Harrisburg bound for Altoona. Blue Mountain dominates the distance. Brad Mann Collection.
Here is a duplicate 35mm color slide of a photo by Charles Houser that was taken in Bay Head Junction, New Jersey, on 5 September 1964. Shown here (R to L) are Pennsylvania Railroad engines #5840 and #5866. Both are EP-20's built by GM-EMD and rated at 2,000 horsepower each. #5840 was built in August of 1947, while #5866 was constructed in March of 1949. ("Tchowee"; #8 of 27)
17th Street. Here is an image of a photo by John Dziobko, Jr., that was taken from the 17th Street Bridge in Altoona, Pennsylvania, on 25 July 1952. This was the site of the Pennsylvania Railroad's engine ladder and ready tracks at 17th Street, now long gone. Passing under the Bridge is a PRR passenger train pulled by an A-B set of unidentified EP-20's built by GM-EMD and rated at 2,000 horsepower each. (Perhaps it's E-7A #5840.) The train will stop at the Altoona Passenger Station for crew changes, as well as to discharge and receive passengers, before resuming its journey to Harrisburg and points East. Parked near the trainshed is a K-4S (4-6-2) "Pacific" steam locomotive, waiting for its next helper run up the Allegheny Mountains via the Horseshoe Curve to Gallitzin and back. William E. Burket Collection.
