Howe Sound, Pemberton Valley & Northern


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 13555)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p. 172 . Works number was 34270 in February 1910.

Clearly based on the saddle-tank design sold to, among others, the nearby Seattle Southwestern in 1907 (Locobase 13040), this engine operated in British Columbia. It was operated with a tender on the line, which was almost immediately renamed the Howe Sound & Northern. The HS & N was taken over by the Pacific Great Eastern in November 1912 and ran for 8 more years before being sold. During their tenure, according to the WCRA, the 2 hit a gas-motor car and demolished it. This particular accident, which was an increasingly common kind of mishap, fortunately resulted in no fatalities.

Comox Logging of Ladysmith, BC bought the engine, renumbered it 7, and ran it for decades.

In November 1967, the City of Squamish gained title when Crown Zellerbach donated the 7. In 1993, the City of Squamish sold the engine to the West Coast Railway Association, a preservation group that restored the 2 to PGE colors. As of Locobase's 19 December 2011 visit to the WCRA website ([]), the group planned to restore the 2 to operating condition if the boiler proved sound.
