Richland Parish 2-4-2 "Columbian" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 13707)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 30 and Volume 36, p. 113. Works number was 35081 in August 1910.

Immediately after Louisville's Mengel Box Company's second 2-4-2 for its Hickman, Ky operations (Locobase 13496) came off the line, Baldwin produced a twin for the Rayville, Louisiana timber company. About 9 years after it went to Louisiana, however, the 1 wound up with its twin sisters on the Timber Railroad.
