Centennial Narrow Gauge 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Schuykill (Locobase 9681)

Data from Emory Edwards, Modern American Locomotive Engines, (Philadelphia: Henry Carey Baird & Co, 1883), pp. 120, 122. Baldwin works numbers 3878 in May 1876.

Like the 2-6-0 shown in Locobase 9680, this engine was acquired by the Easton, PA-based West End Railway Company to operate on a narrow-gauge line at the 1876 Centennial Exhibition. It's interesting that the larger boiler went on the Eight-wheeler and not the Mogul. The 4-4-0 also had fewer fire tubes with larger diameters.

After not being delivered to the Manhattan Beach Railway, the Schuykill was sold to the Foxburg, Saint Petersburg & Clarion in western Pennsylvania (part of the Pittsburgh & Western network) in 1878 as their #1. The FSP & C was sold to the Pittsburgh, Bradford & Buffalo in 1881 and the engine went along as its #1. This railroad also was part of the P & W network, which the #1 served until it was sold in January 1892 to the Altoona & Wopsononock Railroad, which was reorganized in 1893 as the Altoona, Clearfield & Northern Railroad, which in turn was reorganized in 1897 as the Altoona & Beech Creek Railroad.
