|24th Street. Here is an original photo that I took of a Pennsylvania Railroad train in Altoona, Pennsylvania, on 11 October 1963. Shown here (L to R) are PRR engines #5850, #5803, and #5849. All were built by EMD. #5850 and #5849 are EP-20's built in 1947 and rated at 2,000 horsepower each. #5803 is an EP-22 built in 1952 and rated at 2,500 horsepower. They are about to pass under the 24th Street Bridge and will shortly stop at the Altoona Passenger Station for a crew change with a 27-car mail/express train. The famous Brick Plant is visible in the right center of the photo.
