Colorado & Wyoming 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 7 (Locobase 12426)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 23, p. 62. Works numbers were 18092 in September 1900, 19795 in November 1901, and 19813, 19840 in December.

Colorado Fuel and Iron operated a variety of iron mines, coal mines, steel mills all across Colorado and in Wyoming. In 1908, the Directory of Iron & Steel Works described its railroads. There was the Crystal River Railroad Companyoperating 21 miles of standard and 12 miles of narrow gauge track in Garfield and Pitkin counties. The CRRR was known as the "marble road" as it exploited marble deposits, some or all of which may have been used in steel making.

The Colorado & Wyoming had three separate (and separated) divisions. The Northern division included 17.9 miles of track in Laramie county, Wyoming. Middle division was the biggest with 94.6 miles around Pueblo's Minnequa Steel Works. And the Southern division's 58.2 miles were located in Las Animas county, Colorado.

The C & Ws were quite typical of the hundreds of standard-gauge designs produced in this period and fell in the middle of the pack.
