Holston Valley 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 12558)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 24, p. 76. Works number was 19610 in October 1901.

This mid-size Consolidation served several narrow-gauge line in several states. Holston Valley was a lumber road connecting Bristol with Big Creek in Tennessee. Soon after its arrival on the HVRR, however, it was sold to Virginia's Farmville & Powhatan, which was just then emerging from receivership under the new name Tidewater & Western.

Locobase 13687 describes the unusual end of the T & W in 1917. At that point, the 4 was sold off to locomotive rebuilder/reseller Southern Iron & Equipment. The SI & E sold the engine to the 29.8-mile long West Virginia Midland, which connected Holly Springs and Webster Springs. The WVM operated until 1931.
