Everett Iron Company 0-4-2 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Alpha (Locobase 11813)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 11, p. 214. See also "American Iron and Steel Institute , Earlston Furnace, Everett Iron Company (Everett, Pa.)" from the Hagley Museum of Delaware digital collection at [], last accessed 29 October 2022; and [], last accessed 29 October 2022. Works number was 6774 in May 1883.

This Pennsylvania furnace (possibly the Earlston furnace, which was built in 1884) bought a little tank that would pull a reasonable number of dump cars. The photo from the American Iron and Steel Institute archives shows two different elevated trestles leading to the furnace up which the Alpha might have climbed. The furnace went into blast 10 December 1884.

The new furnace didn't improve company finances in part because of poor quality iron ore and the company went into receivership. But Joseph Earlston Thropp was able to buy the business in 1889. He ran the company with some success, but entered bankruptcy in 1924 and the furnace was closed.
