Hebard Cypress Company 2-6-2 "Prairie" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 14034)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 52, p. 307 and Volume 71, pp. 254+. (Thanks to Chris Hohl for his 21 November 2015 email noting the tender capacity.) Works numbers were 41863 in January 1915 and 55301 in March 1922.

Hebard's operations in Florida offered some challenges to these logging Prairies, including 2 1/2% grades in some places, but the grades were never more than 10 degrees (574 foot/ 175 metre radii) on the level and only 5 degrees (1,146 foot/349 metre radii) on the steepest grades.

Locobase doesn't know when the 4 was sold to Ford, but can say that it was renumbered twice by the auto builder to 7 and 24. Ford owned lumber holdings in northern Michigan. 5 also went to Ford and was renumbered 26.

The 24 was sold in 1933 to Menominee Sugar Company.
