| Here is a photo that was published originally in the April 1964 issue of "Trains" magazine, page 38. It was the lead photo of an 11-page article by Bert Pennypacker entitled "All About America's Largest Locomotive Fleet." Photo Caption: "Low-nose GE U-25B's 2500, [2508], and 2502 exert a total of 7500 h.p. climbing westward around Horse Shoe Curve." Shown here (L to R) are Pennsylvania Railroad engines #2500, #2508, and #2502. All are GF-25's built by General Electric in 1962 and rated at 2,500 horsepower each; #2500 and #2502 were constructed in August, while #2508 was built one month later. |
