Class Details by Steve Llanso of Sweat House Media
Class E (Locobase 1329)
Data from ([
]) and from
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p 111.Works numbers were 32256-32257 in November 1907, 32347 in November, 33751 in September 1909.
Passenger locomotives originally delivered with 64" drivers, but diameter was soon increased to 67". 500 pressed 180 lb and had a slightly lower TE.
All sold to Duluth Iron & Metal Company for scrap in 1933.
