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.
