Weirton Steel Company 0-6-0 "Switcher" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 102 (Locobase 15005)

Data from Roy V Wright (Ed.) 1922 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1922), p. 999. Works numbers were 58808-58809 in 1919.

Weirton, WVa was the home of this giant steel mill, which opened in 1909. National Steel Corporation acquired it in 1929.

When the mill looked ready to close in the early 1980s, WSC employees initiated an employee-takeover plan in 1983. Although having to resort to public stock offerings that reduced the employees' share in 1994 to 49%, the works remained open into the 21st century.
