Class Details by Steve Llanso of Sweat House Media
Class 5 (Locobase 15320)
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 73, pp. 374. See also Paul C Leibe, "Trains once rolled regularly through St Mary's", 27 December 2006 archive by SoMdNews.com at [

Railroad" at [] Works number was 58005 in September 1924.
Based in Charlotte Hall, Maryland, the WP&LP was only the latest incarnation of this railroad, which was originally chartered as the Southern Maryland Railroad in 1869. The two citations above give the details of the complicated history of the railroad, which gained its name in 1917. At the time, the line was on the verge of abandonment, but local farmers combined to buy the line.
It was during this period that the WB&LP bought this small Mogul. After about fifteen years in service, the 5 was sold to the Hoosac Tunnel & Wilmington in August 1938, where it operated until it scrapped in 1949.
