Hocking Valley / Holston Valley 2-8-0 "Consolidation" Locomotives in 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.


Class C8 (Locobase 7852)

Data from Hocking Valley 9-1924 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 5957-5966 in June 1903.

While Brooks was delivering its orders of Belpaire-firebox Consolidations (see Locobase 7851), Rogers added ten more very similar locomotives with a round-top boiler, six more boiler tubes, and a slightly larger grate and firebox.

For some reason, the HV had disposed of the entire class by the time the Chesapeake & Ohio absorbed it in May 1930.
