Pittsburgh, Cincinnati, Chicago & St Louis 2-4-0 "Porter" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 12295)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21, p.254. Works number was 16240 in October 1898. See also John H White, The American Railroad Passenger Car, Volume 2 (Baltimore, MD: Johns Hopkins University Press, 1978), pp. 585-587

Locobase 12237 outlines the history of this very short-lived type - the steam coach (steam rail motor in England) in which the front section held the vertical boiler and the running gear underneath while the after section held passengers. Like the two others delivered by Baldwin (see also Locobase 12269), this Vauclain compound proved a failure on the Pan Handle Route and was quickly sold to the Cincinnati, Lebanon & Northern.
