Frank & Grassy Mountain 2-6-0 Locomotives in Canada

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 12658)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 25 p. 216. Works number was 21659 in March 1903.

Originally intended for the Little River Lumber Company of California, this Mogul instead was sold to the UGF of BC. That line ran from the town of Frank in Alberta (or from the CP junction nearby) north "...through townships seven and eight, range four, west of the fifth meridian in the North-west Territories, to Grassy Mountain in the said township eight.", at least according to the "...Act respecting the United Gold Fields of British Columbia (Limited)", as amended.

Locobase believes that the photograph available at the Atlas of Alberta Railways site, [], is the #1. Its clarity allows the viewer to examine every part of the engine and study its crew. A topographical map also available at the site shows that a) the direction was more easterly along Gold Creek than northerly and b) that Frank was situated at 4200 feet above sea level near Crowsnest Pass on the Canadian Pacific.

The crew worked the trains that served the collieries at Lille

Ultimately, the 1 wound up on the West Canadian Collieries
