Cincinnati & Westwood 2-6-2 "Prairie" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 11986)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 17, p. 61. Works numbers were 12105 in August 1891 and 12360 in December. See [] (last accessed 31 December 2010) for more information on the C & W.

This independent road operated until 1928. It was opened in 1874 as a narrow-gauge line linking the suburb of Westwood to downtown Cincinnati, but never made much money and eventually was closed in 1886 because it was unsafe to operate.

The aptly named James N Gamble (co-founder of Proctor & Gamble) took a flyer on the abandoned line and enlarged the gauge to standard gauge and reopened the line to passengers in 1887. By 11 August 1896, Gamble had to cease passenger operations. It became, in essence, a terminal road, and the tanks provided much of the motive power.

The road closed to most traffic in 1924 and all traffic stopped in 1928. The 1 was sold to Laurentide Pulp Company.
