History

While the 2-8-8-2 had been built in the United States since 1909,E. W. King, Jr. in Drury pp.298–299 most development work had gone into making subsequent locomotives larger and heavier. The Norfolk and Western Railway however, had taken development in a different direction. By using smaller cylinders and higher boiler pressure, the result was a locomotive capable of powerful performance, and a turn of speed higher than the maximum of the ‘traditional’ designs. The USRA 2-8-8-2 drew heavily on the Norfolk and Western Railway’s Y2 class locomotive design, as their delegate to the 2-8-8-2 design committee had brought a full set of
