Class Details by Steve Llanso of Sweat House Media

Class E (Locobase 1329)

Data from (http:/fp-www.wwnet.net/`dulong/dssa/locomot.thm) and from

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p 111.

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 for scrap in 1933.
