Stroudsburg Passenger Railway 0-4-2 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Pocono (Locobase 15810)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 18, p. 55. Works number was 12926 in September 1892.

Like the 1 (Locobase 15811), the Pocono helped the SPR convert to steam dummy. It too was sold in the late 1890s to locomotive rebuilder/recycler Birmingham Rail & Locomotive. BR&L sold the Pocono eight years later in January 1906 to Sanders & Lemack of Ritter, South Carolina, which logged Colleton County. S&Llater merged with Colleton Mercantile & Manufacturing of Ravenel, SC.
