Toledo, Angola & Western 2-8-2 "Mikado" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 100 (Locobase 12875)

Data from "Elk River Coal & Lumber Company #10 Steam Locomotive", United States Department of the Interior National Park Service National Register of Historic Places (NPS Form 10-900), signed 7 August 2006 by Randall Reid-Smith, SHPO. Works number was 65430 in April 1924.

The TA&W was a 10 1/2 mile (16.9 km) long switching railroad in the Toledo area that used this light Mikado for 25 years. In December 1949, the TA&W went over completely to diesel power by replacing the 100 -- its only locomotive -- with an Alco S-1 switcher.

West Virginia's Elk River Coal & Lumber Company bought the 100, renumbered it #10 and ran it for nine years of short runs from the coal mines to the "gob pile".

In 1963, the ERC&L's corporate successor Pittson Coal Company gave the #10 to Huntington Railway Museum, Inc. The #10 was moved to Huntington, cosmetically restored, but relettered and renumbered to resemble the last Baltimore & Ohio steam locomotive to serve Huntington. Heritage Village opened in 1977 to house the #10 and several other historical structures and rail equipment. The #10 regained its number and ERC&L lettering in 2000.
