Tremont & Gulf 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 19 (Locobase 12892)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 30, p. 227. Works numbers were 30777, 30866 in May 1907.

The 20 was eventually sold to the Tavares & Gulf, the Tropical Trunk Line (or "Tug and Grunt") based in Florida.


Class 25 (Locobase 12895)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 48, p. 259. Works number was 40318 in August 1913.

Like most of the bought-new T & G locomotives, this Ten-wheeler stayed with the short line for decades. Only in 1953 was it sold to Dunham-Stephens
