Pittsburgh & West Virginia 2-8-2 "Mikado" Locomotives in the USA

The Pittsburgh & West Virginia Railway operated in the Pittsburgh, PA and Wheeling, WV areas. It was built as the Wabash Pittsburgh Terminal Railway, a Pittsburgh extension of the Wabash Railroad. The railway went into receivership in 1908 and the line was cut loose from the Wabash. It did ok on its own and even built an extension in 1931 to connect to the Western Maryland Railway at Connellsville, PA. The P&WV had 112 miles of main line track extending from Pittsburgh Junction, OH, through parts of West Virginia to Connellsville, PA and approximately 20 miles of branch lines.

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.

Class 1010 (Locobase 7875)

Data from P & WV 12 - 1937 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

An interesting Mikado that was a bit smaller and lighter than the USRA Light Mike design that appeared later in the year.
