Cincinnati, Lebanon & Northern 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class D-37 (Locobase 12105)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 101. Works numbers were 14002 in April 1894; 14004-14005 in May.

Locobase was at first startled when he saw that this trio of locomotives had virtually the same specifications, point by point, as had the Lebanon Springs Eight-wheeler produced in 1890 (Locobase 11696). But further research showed over a dozen American 4-4-0s with very similar numbers. It was the last gasp of standardized deep, narrow fireboxes before adoption of the wide firebox would open up American design and production.

An interesting note in the spec was "Boiler to carry water on 3% grade", that is not to take an angle so extreme as to expose the crown sheet.

Gene Connelly wasn't able to pin down the subsequent careers of these three engines very cleanly. Two may have gone to the Lake Erie & Detroit River; these may have later turne up as Pere Marquette 806-807. 3 certainly seems to have wound up on the Pontiac, Oxford & Northern as their #9. A year later, the PO & N would come under the Grand Trunk's sway and this engine was renumbered 2337.
