Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 192-193. (Many thanks to Chris Hohl for his 5 August 2018 email noting the mismatch between the data from the source and the data originally shown in entry. Serious Locobase operator error caused by copying another record [Locobase 5148] and not changing the data.) Works number was 4281 in April 1895.
This 5 3/4-mile railroad served resort towns in the Catskill Mountains and was operated by the Albany and Susquehanna Railroad Company. The "Middleburg" ran on this line until the railroad was abandoned in 1936, after which it was scrapped.
