Brooklyn, Bath & Coney Island 2-4-0 "Porter" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class May C (Locobase 11800)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 11, p. 76. Works number was 6738 in March 1883.

This tank was one of the steam dummies that powered the railroad that connected Brooklyn to both Bath Beach and Coney Island beginning in 1864.. The BB & CI was reorganized on 1 December 1885 as the Brooklyn, Bath & West End Railroad and the May C continued in service until the line was electrified in 1893. The redundant locomotive may have been sold to the large contracting firm of Norcross Brothers.
