Berkeley Railroad 0-4-4 "Forney" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 12280)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 20 p. 29. Works number was 16016 in June 1898.

D L Risley was the President of this South Carolina short line, which linked Chicora and Monck's Corners with 10 miles of line; Monck's Corner was located 31 miles north of Charleston. According to Wikipedia: "The Berkeley Railroad was built by A.S. Emerson, an early real estate developer who wanted to promote a development he called "New England City", in Berkeley County."

Interesting name to try to promote in the founding state of the Confederacy. Perhaps that's why New England City failed and the line was sold at auction in July 1906 to a local lumber company.
