Chicago Great Western 2-10-4 "Texas" Locomotives of the USA

Needing new motive power in the late 1920s, the Chicago Great Western Railroad placed orders with the Lima Locomotive Company and the Baldwin Locomotive Works for "Texas" type locomotives.

The first to arrive were fifteen of the 2-10-4s (road numbers 850 through 864) from Lima in 1930. Another three (road numbers 880 through 882) came from Lima in the same year. These eighteen locomotives were designated as Class T-1 and had 63" diameter drivers, 29" x 32" cylinders, a 255 psi boiler pressure, a tractive effort of 84,600 pounds and each weighed 462,900 pounds.

Another nine, "Texas" type locomotives were received from Baldwin in 1930. These locomotives were built to the same basic specifications as the T-1s, but weighed 463,980 pounds. They were designated as Class T-2 and were assigned road numbers 865 through 873.

All thirty-six of the coal burning CGW "Texas" type locomotives were retired between 1948 and 1950, and today there are no surviving examples

Class Details by Steve Llanso of Sweat House Media

Class T1/T2/T3 (Locobase 1187)

Data from tables and diagrams in 1930 Locomotive Cyclopedia and from CGW 1 - 1943 locomotive diagram book supplied in March 2004 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Vol 82, pp. 186+. Baldwin's works numbers for road numbers 865-879 were 61573-61587 in December 1931. Lima works numbers were 7501-7515 in April 1930, 7569-7571 in December.

Firebox heating surface included 98 sq ft in two thermic syphons (9.1 sq m), 91 sq ft (8.45 sq m) from the combustion chamber, and 21 sq ft (1.95 sq m) of arch tubes. All had 14" (356 mm) piston valves.

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 [Type S] feedwater heaters."

The 1943 diagram book 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 aRaildata 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 huge 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."

Batch summaries:

T-1 850-864 Lima 1930, 880-882 Lima 1931

T-2 865-873 Baldwin 1930 - Worthington feedwater heaters

T-3 874-879 Baldwin 1931 (Baldwin works numbers came in a batch 61573-61587 in December 1930) - Coffin feedwater heaters.

883-885 Lima 1931

All left service in 1948-1950.
