Class T1/T2/T3 (Locobase 1187)

Firebox had combustion chamber and thermic syphons, boiler had feedwater heater, valve gear had limited cutoff. Firebox heating surface included 98 sq ft of thermic syphons and 21 sq ft of arch tubes.

Drury (1993) claims that these were duplicates of the Texas & Pacific 600-series locomotives -- and in terms of basic power, they were. He notes the few differences: "coal instead of oil fuel, a second sand dome behind the steam dome, and Coffin or Worthington feedwater heaters."

But data from the CGW's 1943 locomotive diagram book (supplied by Allen Stanley from his extensive collection in March 2004) suggests a very different origin. Alone among the American and Canadian 2-10-4s, these locomotives retained the 5 1/2" flues for the superheater. The areas are considerably smaller than those of the T&P engines.

An interesting vignette on the impact of these "Big Hogs" comes from a collection of stories about the CGW put up on http://www.trainweb.org/cgw/history-bin/true_tales.html by Jim L. Rueber (visited 11 August 2004):

"To help pay for these hugh engines" Rueber says, "a lot of employees lost their jobs. The shop force at Oelwein, Iowa was reduced. The Terminals at East Stockton, Illinois and Conception, Missouri were closed. These bigger engines resulted in fewer trains so the trainmen and enginemen took a hit. Even the operators at the various coal chutes were reduced to just one man."

Rueber adds that when a superintendent asked engineer Frank Anderson whether he liked the new engines, Anderson replied, "I don't". When Foster, the super, followed with "Why not?", Anderson said, "They pull too many cars."
