PRR 8671, AS-18AM, 1959
Title:  PRR 8671, AS-18AM, 1959
Description:  Muleshoe. Here is a photo by William D. Volkmer that was taken at the Muleshoe Curve on the New Portage Branch Line west of Duncansville, Pennsylvania, on 29 October 1959. It was published originally in his 2019 book entitled "Pennsylvania Railroad-Best Of Bill Volkmer: Volume 3-Altoona," page 81. Shown here (L to R) are PRR engines #8671, #8674, and #8677. All are AS-18AM's built by the American Locomotive Company in March of 1958 and rated at 1,800 horsepower each. They are pushing an iron-ore train up the Allegheny Mountains to Gallitzin, where they will uncouple and return to East Altoona for yet another run up "The Mountain."

PRR 8671, AS-18AM, 1964
Title:  PRR 8671, AS-18AM, 1964
Description:  17th Street. Here is an original photo that I took in Altoona, Pennsylvania, on 25 April 1964. Shown here (R to L) are Pennsylvania Railroad engines #8671, #8677, and #8678. All are AS-18AM's built by the American Locomotive Company and rated at 1,800 horsepower each. #8671 was built in March of 1958, while #8677 and #8678 were built in April of 1958. In this context, they're serving as tail end pushers on a mixed-cargo freight train that's heading up the Allegheny Mountains to Gallitzin, where they'll be uncoupled and returned to East Altoona for further assignment. Note the trainphone apparatus on N-8 cabin car #478216. Partially visible on the far side of the 17th Street Bridge are some of the PRR's 12th Street Car Shop buildings.

PRR 8677, AS-18AM, 1965
Title:  PRR 8677, AS-18AM, 1965
Description:  Derailment. Here is an original photo that I took at the site of a derailment in Altoona, Pennsylvania, on 21 May 1965. At the left is Pennsylvania Railroad engine #8677, an AS-18AM built by the American Locomotive Company in April of 1958 and rated at 1,800 horsepower. It's coupled to the "eastern" work train and steam-powered crane that are working on the derailed cars and locomotives of the eastbound freight train on the next track over. Visible in the center (L to R) are the two derailed locomotives, PRR engines #5631 and #8890. Both were built by the American Locomotive Company and rated at 1,000 horsepower each. #5631 is an AS-10AM built in August of 1950 and #8890 is an AS-10 built in December of 1950. At this point in the clean-up process, they remain coupled to a single box car: CGW 9166. Visible in the background are two of the original PRR 12th Street Car Shop buildings. A portion of 10th Avenue is visible in the foreground. (#10 of 14)
