According to a roster published in 1941 the Pennsylvania Railroad owned 582 2-10-0 or Decapod type engines, the mainstay of its coal hauling operations in its namesake state. The vast majority of these, or 501 engines, belonged to class I1s, including No. 1753 appearing in this shot by an anonymous photographer. No. 1753 was built by the railroad's Juniata shops at Altoona in 1918. She had 30½x32-inch cylinders, 62-inch drivers, and 250 p.s.i. of boiler pressure. These locomotives weighed 352,500 pounds without their massive 16-wheeled tenders. They had 4590 square feet of evaporative heating surface and 1643 square feet of superheating surface, and put forth a hefty 90,024 pounds of tractive effort. These Decapods were noted for their "banshee" or one-toned whistle, and the signature double air reservoirs visible on No. 1753's pilot. Only one I1, No. 4483, cheated the scrapper's torch.
