| RR City. Here is an original photo that I took in connection with the Pennsylvania Railroad's "Railroad City Limited" in Altoona, Pennsylvania, on 25 April 1964. Shown here (R to L) are PRR engines #8609, #8610, and #8606. All are APS-24MS's built by the American Locomotive Company and rated at 2,400 horsepower each; #8609 and #8610 were built in 1956, but #8606 was built in 1955. They are running light to the Altoona Passenger Station where they will couple onto the 18-car "Railroad City Limited" for its journey out the Hollidaysburg Branch Line, up the New Portage Branch via the Muleshoe Curve, making a loop through the tunnels at Gallitzin, and then heading down the Allegheny Mountains via the Horseshoe Curve to the Altoona Station. This photo was taken adjacent to ALTO Tower, just short of the 17th Street Bridge. |
