Cincinnati & Westwood 2-8-2 "Mikado" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 13919)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 41, p. 142. Works number was 37531 in February 1912.

The C & W was an interurban line that connected Cincinnati with a nearby suburb. As early as 1905, however, it was clear that the road's alignment simply couldn't compete with other passenger service. However, the route was useful for conveying coal and other freight and the 3 was purchased to provide additional motive power. See Locobase 11986 for more details about the railway.

The line closed in 1924 and further details about the 3's career are not available.
