Class 2 (Locobase 15413)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 79 pp. 8+. See also Richard A Rajala, Clearcutting the Pacific Rain Forest: Production, Science, and Regulation (Vancouver, BC: UBC Press, 2011), pp. 62-63 and the Preserved Steam BC website's detailed account of the 2/7/1007/1055/18/1055/7's history at [], last accessed 5 September 2013. Works numbers were 60942-60943 in August 1929.

Rolling on 56 and 60 lb/yard (28 and 30 kg/metre) rail, these two oil-burning, superheated logging Mikados were presented with daunting 9% grades and tight 30-35 degree curves (radii of 191 and 164 feet). The specs said that the oil would be relatively light at 17-18 degrees Baume (specific gravity of .947 to .953).

Campbell River sold and Alberni Pacific of Franklin River and the two tanks were renumbered by 7-8. The 8 was scrapped after 1957 for parts, but the 7 became a numerology exercise, eventually bearing five different numbers. Alberni closed in 1953 when it left the logging business and sold the 7 to to MacMillan Bloedel and renumbered 1007. A year later in 1954, the 1007 plunged through a bridge over the Franklin River, killing both engine crewmen. Although recovered and repaired, the 1007 took a new number: 1055.

Leased briefly by Comox Logging in 1959, the 1055 took the number 18, it returned to MacMillan Bloedel. Incredibly, the latter company kept the 1055 in mainline service until 1969 and operated the engine as a switcher until 1971.

In one of those oddly foresightful acts, the BC government bought the 1055, placed it in storage, held onto it until 1991, and donated it to Port Alberni. Its first restoration was completed in 1995, but a more complete overhaul in 1999 greatly extended its service life. Remarkably, this stubby saddle tank remained in tourist service in 2013.

Much later, the 1055 regained its CRTC number as it entered tourist service on the Alberni Valley
