PRR ROSE Tower, 1963
Title:  PRR ROSE Tower, 1963
Description:  8th Street. Here is an original photo that I took in Altoona, Pennsylvania, on 10 August 1963. Shown here (L to R) are the Pennsylvania Railroad's ROSE Tower (in white), the 8th Street ("Red") Bridge, three ALCo road switchers waiting for their next assignment. and a Baldwin-built switcher shifting freight cars at the far right. Visible in the foreground are the west- and eastbound passenger/through tracks, as well as position-light Signal #2344. The three PRR road switchers shown here are numbers (R to L) #8663, #8660, and #8672. All are AS-18AM's built by the American Locomotive Company and rated at 1,800 horsepower each; #8663 and #8660 were built in January of 1958, while #8672 was built in March of 1958.

PRR 8670, AS-18AM, 1964
Title:  PRR 8670, AS-18AM, 1964
Description:  Wye Switches. Here is the third of seven successive original photo that I took at the Wye Switches in Duncansville, Pennsylvania, on 5 October 1964. Shown here (R to L) are Pennsylvania Railroad engines #8670, #8660, and #8673. All are AS-18AM's built by the American Locomotive Company and rated at 1,800 horsepower each. #8670 and # 8673 were built in March of 1858, while #8660 was built in January of the same year. These three units, PRR cabin car #477781, two freight cars, and three lead locomotives have just arrived from Altoona, proceeded up the New Portage Branch line for a short distance, and are now stopped. In a short while, they'll back into the Hollidaysburg Yards, pick-up a freight train, and then proceed up the New Portage Branch to Gallitzin and points West. Duncansville's Fifth Street is visible in the center, Second Avenue is at the left, while Third Avenue/US Route 22 is at the right. From 1834 to 1854, this was the right-of-way for the Allegheny Portage Railroad.
