Cornwall & Lebanon 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 10 (Locobase 11869)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 13. p 216. Works number was 8542 in May 1887.

This Eight-wheeler had a long, shallow firebox for burning anthracite coal. 30 years after it entered service, the 10 accompanied several other C & L engines as they merged with the Pennsylvania's stud in 1918. Placed in the D odd class (along with a medley of other outliers), the 3689 remained on the roster for another 5 years until it was scrapped in October 1923.
