| Here is page 16 of a 64-page booklet published by Harry P. Albrecht entitled "World Famous Horseshoe Curve, Altoona, Pennsylvania Railroad." It was first issued in September of 1973. Partial Photo Caption: "Looking eastbound this picture, taken about 1912, shows how [Kittanning Mountain] was 'sliced-off' so that the tracks might make a giant semi-circle, forming the Horseshoe Curve on the Pittsburgh Division, six miles west of Altoona." |
