Class Details by Steve Llanso of Sweat House Media

Class Analomink (Locobase 15811)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 16, p. 104. Works number was 11183 in September 1890.

Although the SPR had been constructed and opened in 1870, it was served by horse-drawn tram cars until 1892. An 1889 report notes the railway's modest scale. Its horse-traction service averaged 15 miles an hour on 28 and 30 lb/yard (14-15 kg/metre) track that ran for 1 5/8 miles (2.6 km) down Main Street in Stroudsburg and East Stroudsburg to the Delaware, Lackawanna & Western railroad station. . Each horse traveled 12-14 miles a day and a typical run required 15-20 minutes running time.

In 1892, when the company was reformed under a new franchise specifically to convert from horse to steam traction, the roadbed was completely rebuilt. It ran for 2 miles on 45 lb/yard (22.5 kg/metre) rail. The Analomink and its larger Baldwin stablemate each pulled one of the five trail cars on the roster.

Indeed, this Baldwin was quite the smaller of the two. It was originally ordered by the Rapid Transit Company of Baltimore, but was perhaps too small for that larger city's traffic demand.

The 1 was sold in the late 1890s to locomotive rebuilder/recycler Birmingham Rail & Locomotive. BR&L found a buyer in McClure Lumber of Eutaw, Alabama, which named the dummy Eutaw. McClure returned the Eutaw to BR&L, which sold it in October 1908 to Alabama Consolidated Coal & Iron.
