These locomotives were used 1930-1932 during construction of the massive hydro-electric dam and powerhouse on the St. Lawrence river. Engines became Beauharnois Light Heat & Power Co. 111-124. 112 and 114 sold 1940 to Defense Industries Ltd. 2001, 2002. (At least one of which was resold to National Steel Car) 118 sold to Quebec Sugar Co. 121 and 124 sold May 1935 to Falconbridge Nickel Mines 102, 103. They converted both to coal account oil firing not suitable for plant switching. Then, in 1950 FNM 103 was sold to M. J. Poupore Lumber Co. (owned by Falconbridge) in Skead. Around 1935-40 123 was sold to Cooksville Brick & Tile, Cooksville. Three more were sold for export to Japan and 5 were scrapped around 1950 by Andrew Merrilees (D), who could no longer market steam locomotives.

CNR locomotive engineer Alexander P. Brown of Parry Sound bought 124 (CLC #1896 2/30) in July 1969 in derelict condition and restored it to operation on a very short piece of track on his rural property. Upon Alex's death it went to Don Broadbear, who was (2003) restoring it in St. Thomas, to operation. In 2010 # 124 was moved to the new locomotive repair shop in St. Jacobs for the restoration to be completed.
