Data from DeGolyer, Volume 13, p. 159 and CN Steam Locomotive Diagrams Assorted supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 8285, 8287 in December 1886, 9130 in January 1888, 9130 in March.
Over their nearly forty years of operation, the basic specifications for this quartet of Eight-wheelers changed very little. The 1888 locomotive boilers had two fewer tubes and the tender held 500 US gallons (1,893 litres) more water. At some later date, their driver diameters grew by an inch to 69" (1,753 mm).
They were, however, renumbered several times. The CAR gave them 609-612 in 1888. After the CAR's amalgamation with the Grand Trunk, they were renumbered 1320-1323 and renumbered again in 1910 as 2119-2122. Finally, the Canadian National took over the GTR and renumbered the four in 1923 to 244-247. Even then they had differences in detail rather than significant variations.
247 was scrapped in November 1924, followed by 246 (December). 244-245 were sent to the ferro-knacker's in June 1925.
