Colorado Southern & Cripple Creek District 2-6-0 "Mogul" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 7702)

Data from CC&CS 1912 Locomotive DiagramRaildata collection supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 5625-5626 in August 1900, 6135 in July 1901, and 25623 in April 1901.

See Locobase 7699 for a brief description of this railroad. The four Prairies were small, stubby engines with the trailing axle behind the firebox. The tender sloped down in back, which suggests these locomotives were also used for switching.
