The Pittsburgh & West Virginia Railway bought only three new "Mikado" type locomotives. They were built by the Baldwin Locomotive Works and were delivered in 1918 and given road numbers 1000 through 1002. These locomotives had 63" diameter drivers, 26" x 30" cylinders, a 200 psi boiler pressure, they exerted 54,724 pounds of tractive effort and with its booster 65,124 pounds and each weighed 305,311 pounds. The firebox was 259 square feet, the evaporative heating surface was 3,497 square feet and with the superheater the combined heating surface was 4,379 square feet.
In the late 1940s, five second-hand "Mikados" were put on the roster. One came from the CI&L and the other four came from the CRRNJ.
There are no surviving P&WV 2-8-2 "Mikado" type locomotives.

Data from tables in 1930 Locomotive Cyclopedia and from American Locomotive Company, Standardized Locomotives, US Railroad Administration (Alco Pamphlet 10049, 1918), pp. 16-17, reprinted by (Ocean, NJ: Specialty Press , 1973) and DeGolyer, Volume 58, pp. 61+. Works numbers were 49679-49681 in September 1918.
625 engines were built to very successful United State Railroad Administration light Mikado design in 1918-1919. These three were the only 2-8-2s built new for the P&WV. They were joined by four more that came much later in 1945 from the Central Railroad of New Jersey. Firebox heating surface included 50 sq ft (4.7 sq m) in the combustion chamber and 27 sq ft (2.5 sq m) from four arch tubes. Cylinders were served by piston valves measuring 14" (356 mm) in diameter. The 1002 went to the scrapyard in 1945. 1000-1001 joined the steam departure parade on the P&WV as the ferro-knacker claimed them in 1951 and 1952, respectively.
