Detroit Iron & Steel 0-4-0 "Switcher" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 15029)

Data from Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 154. Works number was 48349 in August 1910.

M A Hanna & Company were the buyers and they sent this saddle tank to Michigan. Locobase suspects that the count of 164 tubes given in the Locomotive Cyclopedia was a typographical error and that 154 tubes was a more likely figure given the stated tube heating surface area. Note the long wheelbase for an 0-4-0 saddle tank.
