Long-Bell Lumber 2-8-2 "Mikado" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 803 (Locobase 14274)

Data from [] . Works number was 66275 in 1925.

Locobase 14273 describes the basic design of this Alco logging Mikado. It began its varied career on Long-Bell, which was based in Ryderwood, WA. The 803 was sent to Longview Lumber's Portland & Northern Railway. In 1947, the LP&N added a tender and operated the engine even as it went back to Long-Bell, which was later bought out by International Paper in 1956. By 1959, the engine was idled as a stationary boiler at the Longview sawmill.

Eventually, the 803 was owned by the Puget Sound Railway Historical Assn of Longview, WA.
