Locobase 9069 shows the Grand Trunk's compounds of the same year. The Shore Line's Moguls had a longer stroke and eight fewer tubes.
The TStL rebuilt the class as simple-expansion, superheated engines. 1 and 6 were scrapped in 1929 and 2-5 in 1934.
A trio of Moguls for the western Canadian prairies. Purchased by the railway that would be better known after 1908 as the Duluth, Winnipeg & Pacific. Even with that name, the railway didn't connect directly to Winnipeg, let alone the Pacific Ocean. Its Canadian terminus, Fort Frances, Ontario, met the Canadian Northern mainline.
All served the CV for almost forty years. Six were scrapped in the mid-to-late 1920s. 315 was retrofitted with a new boiler by Alco in 1921. The vessel was pressed to 160 psi and held 246 tubes. This rejuvenation delayed the 315's retirement and scrapping until June 1934.
Very similar to most other Grand Trunk Moguls, these four went to the D&TSL. The specs show a tender that weighed 120,000 lb (54,431 kg)
Apparently they were never superheated before they were scrapped in 1929.
