English Lumber Company 2-8-2 "Mikado" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 8 (Locobase 14942)

Data from DeGolyer, Volume 65, pp.114. Works number was 53255 in May 1920.

The ELC was one of many Northwest loggers and was the successor to the Clothier & English lumber company that began timber harvesting at Barney Lake in 1882. The 8 (later 10) was the latest of the ELC's locomotives and was a typical Baldwin logging Mikado. It had a saturated boiler and 25 sq ft (2.3 sq m) of arch tube that contributed to the firebox heating surface.

Such engines moved around during long operating careers. The ELC sold the 10 to the Twin Falls Logging Company, who replaced a very similar 103 with this engine. In May 1943, the TTLC sold the 103 to Red River Lumber Company in northern California as its 105 (joining the virtually identical 104). Less than a year and half later, the Red River's assets were sold to the Fruit Growers Supply Company. The locomotive was scrapped in August 1950.
