Data from "Recent Schenectady Locomotives," The Railway Ages (24 November 1899), p. 877. See Colin Churcher's roster -- [], last accessed 10 April 2010. (Many thanks to Chris Hohl for his 20 May 2017 email with builder's card attached that corrected several points of data.) Works numbers were 5104 in July 1899 and 5464 in 1900.
Like the 2-8-4T described in 11197, this pair of Baltic tanks served the Dominion Coal Company's S&L Railway for decades. They were preceded almost a decade earlier by the Sir Donald, a smaller "Mogul Forney" described in Locobase 20058.
The later pair met distinctly different ends. S&L 44 was later converted to a 2-6-0 tender-engine before being scrapped in 1936. The 43 was sold to the Cumberland Railway & Coal in April 1955. It was scrapped in 1961.
Data from Locomotive Cyclopedia entry archived on line by Old Line Trains at [], last accessed 23 Novmber 2017. For a detailed background essay on the S&L in particular and Cape Breton coal and iron exploration in general, see David Frank, "The Cape Breton Coal Industry and the Rise and Fall of the British Empire Steel Company" Acadiensis (1977), pp. 3-34. (Thanks to Steve Low in his November 1917 email supplying a copy of the LC entry.). Works numbers were 66318 in October 1925.
Ordered from Montreal at the same time as the first of two Mikados (Locobase 16320), this single tank's profile showed relatively small and short side tanks flanking a high-pitched boiler, stubby rear bunker, and long wheelbase.
After twenty years as a tank engine, the 45 was converted to a 2-6-0 with tender. Most likely, the intent was to increase on-board fuel and water stowage.
