Tidewater & Western 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 11 (Locobase 13687)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 35, p. 303. See also George Woodman Hilton, American narrow gauge railroads (), p. 543. Works number was 35192 in September 1910.

The T & W was originally built as the Farmville & Powhatan, which was never very profitable and went into receivership. A June 1905 auction turned the F & P property over to investors that reorganized the line as the Tidewater & Western.

The T & W fared well enough and eventually grew to 50 miles. But in May 1917, according to George Hilton: "The line met an unusual end. It surrendered its charter ...[receiver Langbourne M Williams] arranged sale of the rails and equipment to the French government for use in World War I. The line was dismantled for shipment in June 1918 ..."
