Central Vermont 4-4-0 "American" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class B-16-a/H-2 (Locobase 15639)

Data from [link] (19 June 2003), Rene Gourley's website describing this Eastern Canadian railway. See also Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 19, p. 95. Works number was 14296 in October 1895.

Locobase 5589 shows the two Ottawa, Amprior & Parry Eight-wheelers produced in 1893. As noted, two identical locomotives joined the pair in 1895, but a third stayed in the US to run on the CV's Vermont & Province Line. That line was absorbed by the CAR in 1899, at which point the 30 took number 625. By 1905, the 625 had moved to the Grand Trunk Railway and bore first #1328, then 2237. With the amalagamation the GTR within the Canadian National, the 2237 had #308 by 1913 as its final id.

The 308 remained in service until it was disposed of in July 1925.

NB:The heating surface areas are good estimates derived from a comparison with the #21 of the Matanzas Railroad of Cuba delivered in 1903 and described in Locobase 11540. Not only did both have the same number of identical-diameter boiler tubes running the same length (less 1/2 inch), they also had grates and fireboxes that measured identically to the quarter-inch.
