Data from CV 1957 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Vol 47, pp. 137. Works numbers were 37560-37563 in March 1912.
Modified from the four saturated-boiler Pacifics delivered by Baldwin to the CV in 1912, this class was superheated along the same lines as other classes. The #289 was later transferred to the CN when the CV determined that three passenger Pacifics would suffice for their independent requirements. Those three were scrapped in March 1952 (230, 232) and 1954.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 47, p. 135. Works numbers were 37560-37563 in March 1912.
These were duplicates of the GTR/Baldwin octet that was delivered to the Grand Trunk in 1910 (Locobase 14096). See Locobase 14098 for these engines upgraded with superheaters.
