Escanaba & Lake Superior 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 11 (Locobase 13809)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volumes 45, p. 180 and 39, p.38. Works numbers were 33272 in March 1909 and 33338 in April, and 36809 in August 1911.

At least as far as Baldwin products meant, the 1909 Ten-wheelers represented a substantial step up in size and power from earlier engines. Both of these engines remained with the E & LS for their entire careers; 11 was scrapped in 1943 and 12 sold for scrap in September 1946.


Class 14 (Locobase 13810)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 53, p. 413. Works number was 45083 in February 1917.

A few years after it took delivery of the two Ten-wheelers shown in Locobase 13809, the E&LS returned to Baldwin for a superheated variant of the same design. The usual trade off of tubes for flues saw nearly half of the former replaced by 22 of the latter. Remarkably, the adhesion weight remained about the same and the engine weight gain was held to about 2 1/2 tons.

The 14 enjoyed a long working life. The E&LS put it in reserve when it began operating Baldwin diesels in 1946-1947. In 1963, the company sold the engine to the Arcade & Attica of New York State. The 15-mile-long A & A operated the 14 in tourist service in the Tonawanda Valley until its boiler certificate expired and the engine was stored.
