Botwood 2-6-2 Locomotives in Canada


Class Details by Steve Llanso of Sweat House Media

Class 10 (Locobase 14980)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 65,, p. 357. See also [link] and [link], both last accessed 21 December 2011. Works number was 53503 in August 1920.

This Prairie saddle tank joined the two others from 1909-1910 described in Locobase 13569. Duplicating all the principal dimensions, the 10 weighed 2 1/2 short tons (2.27 metric tons) more.

In 1957, the Grand Falls Central bought the lines of the Anglo-Newfoundland Development Corporation between Windsor, Grand Falls, Bishop's Falls and Botwood. The 10 was scrapped in 1958.


Class 3 (Locobase 13571)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 49, p. 5. See also [link] and [link], both last accessed 21 December 2011. Works number was 33470 in June 1909.

Compared to the two that would follow (Locobase 13569), this saddle-tank Prairie was quite a bit bigger. Was it too big?


Class 4 (Locobase 13569)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p. 224 and Volume 49, p. 3. See also [link] and [link], both last accessed 21 December 2011. Works numbers were 34711 in May 1910 and 38184 in August 1912.

The pair of saddle tanks in this order joined smaller tanks like the 2 (Locobase 13570) in serving the newsprint shuttle between Grand Falls and the port of Botwoodville.
