Works numbers were 57043-57052, 57704-57713. This class owns the distinction of having the biggest-diameter HP and LP cylinders of any 2-6-6-2 Locobase has uncovered. Firebox area was relatively grand as well, the basic hearth heating surface and largest-ever grate augmented by 50 sq ft in 5 arch tubes. The design also had tall drivers.
Eugene Huddleston (Trains, March 1991) tells us that the I-2s were an older design than the USRA Light Mallets that the railroad received just 2 years later (Locobase 7896). Locobase suspects they were good enough for two decades, although likely to run out of steam on main-line freight runs trying to supply those big HP cylinders, but when the much more upt-to-date K-1 2-8-4s (Locobase 64) came on the property in the 1930s, the W & LE shed these compounds quickly. By the end of the 1930s, they had all been scrapped.
Works numbers were 52178, 52268, 52287-52290, 52313, 52330, 52350, 52424. Compared to the Brooks-built 2-6-6-2s delivered 2 years earlier, these had smaller cylinders and drivers , but larger boilers and more firebox heating surface using longer boiler tubes. They were in fact USRA Light articulateds, one of that enterprise's less-successful designs that on the W & LE served mine runs out of Pine Valley, Ohio. According to Eugene Huddleston (Trains, March 1991, p 37), "No one on the Wheeling ever said the USRA Mallets were a bad design; it was just that a use for them could not be found commensurate with their specifications."
Six were scrapped in the early 1940s. The last 4 remained in service until the 1950s, essentially unchanged.
