Hampton & Branchville 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 44 (Locobase 14917)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 77, p. 551. See also the South Carolina Railroad Museum Inc's Project 44 website at [] . Works number was 59751 in January 1927.

This superheated Ten-wheeler freighter had few novelties in its design, but its hotter steam merited 9 1/2" (241 mm) piston valves to deliver the steam to the cylinders.

The 44 operated for the H&B for more than three decades before it was retired in 1959. It was sold in June 1969 to Charleston, South Carolina's chapter of the National Railway Historical Society. Operated in the Southern Railway freight yard for years, the 44 was sold to the SCRM in June 1991 where it went on static display at Wrinnsboro.

Beginning in 2009, the Project 44 Committee began raising funds to restore the 44 to operated on the Rockton, Rion & Western. An assessment of the 44's condition turned up the welcome news that the engine was in remarkably good condition.
