| Here is a photo taken by Bob Lorenz that was published in David W. Seidel's 2008 book entitled "Images Of Rail: Horseshoe Curve," page 39. Partial Caption: "Descending the east slope at Horseshoe Curve is a Baldwin Class BP-60 locomotive set led by No. 5823 powering an eastbound passenger train. These units, at 6,000 horsepower, were initially in passenger service but were later downgraded for freight service [at] only 5,000 horsepower." In this context, Pennsylvania Railroad engine #5823 is a BP-60 built by the Baldwin Locomotive Works in March of 1947 and retired in September of 1962 after just 15 years of revenue service. |
