Marcellus & Otisco Lake 2-4-2 "Columbian" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 13922)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 22, p. 228,. See also Locobase 9647 for a description of the M & OL. Works number was 37520 in February 1912.

About six years and 10,000 builder's numbers after Baldwin supplied a medium-sized saddle-tank to Berlin Mills (Locobase 12909), the Philadelphia builder delivered a very similar engine to a New York State short line. Like the 2-4-0 that preceded it, the 3 had to handle 2% grades and relatively tight 150-ft (46-metre) radius curves. The rails weighed a relatively heavy 70 lb/yard (35-kg/metre).

Unlike the 1, however, the 3's mission was moving freight for the mills in Marcellus and Marietta. After almost 30 years of service, it was scrapped in 1941.
