Woodward Iron Company 2-4-0 "Porter" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 7 (Locobase 12147)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 214 See also Southern Railway's 75th anniversary salute to the WIC in 1959 , archived at http://southern.railfan.net/ties/1959/59-1/wood.html . Works number was 14235 in March 1895.

This small 6-wheeler adopted an unusual wheel arrangement for a mining company in Alabama. After it served the industrial road into the 1920s, the WIC sold the 7 to the Birmingham Rail & Locomotive. BR & L rebuilt the locomotive by adding another axle apparently at the order of Elsberry Brothers company in Wimaume, Fla in May 1925. The conversion must have been unsatisfactory as EB sold the engine back to BR & L in December of the same year.

BR & L removed the extra axle and sold the locomotive to the R L Dowling Lumber Company of Bradenton, Fla. After 5 years, the boomerang took the little engine back to BR & L, which sold it out of the South in May 1930 to Katona Mining in West Lynn, West Virginia.
