EB & AL Stone Company 0-4-0 "Switcher" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 60 (Locobase 15032)

Data from Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 155.

Little oil-burning saddle tank for a stone-quarrying contractor responsible (at the very least) for the Santa Ana River Railroad Bridge in Riverside, California (completed in 1904). See Bridgehunter.com's entry at http://bridgehunter.com/category/builder/eb-al-stone-co/ . They abandoned the Rockaway Quarry near Oakland in April 1919 after railroad rates for handling the stone rose too high.
