Consolidation Freight Locomotive No. 7688
Why it's listed
Built in Lima, Ohio in October 1915, Consolidation Freight Locomotive #7688 is a Class H10s 2-8-0 steam freight engine of the Pennsylvania Railroad. It weighs 127 tons, has 62-inch driving wheels, cylinders measuring 26 by 28 inches, and a tender carrying 8,000 US gallons of water and 34,600 pounds of fuel. Its tractive force is 53,200 pounds. The H10 was the basic freight locomotive in the Central and Western regions of Pennsylvania from 1915 to the late 1930s, where it hauled heavy trains over the grades of the Allegheny Mountains. More than 1,200 H10s were built between 1907 and 1915 at the Juniata Shops, by Alco, and at other shops under contract to the railroad. Locomotive 7688 is the only known surviving example of its class, which is why it was nominated as part of the Pennsylvania Railroad rolling stock group. It was assessed at 0.020 on the group's area calculation, a measure of its footprint used in the nomination.
Significance in brief: The nomination identifies this locomotive as the only known surviving example of the H10s class. The H10 was the last refinement of the H class and the basic freight locomotive in the Central and Western regions of Pennsylvania from 1915 to the late 1930s, serving the rugged Allegheny Mountains. More than 1,200 H10s were built from 1907 to 1915.
