Brooklyn, Bath & West End 2-4-0 "Porter" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 11617)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 72. See Locobase 16616 for a detailed description of the this railroad. Works numbers were 9953, 9966 in April 1889.

The order shown in the specs book depicts a small six-wheeler optimized for fast starts and stops and trailing a four-wheel tender. Sure enough, contemporary photographs show just such a locomotive pulling 3 cars on th surface portion of the BB & WE.

It was a short-lived career. The BB&WE was electrified in 1893 and the 3 was sold to the Nova Scotia Development Company. The 4 may or may not have been completed as a tank locomotive. In 1893, it was sold to Hunters Run & Slate Belt, a 13.5-mile short line in western Pennsylvania.
