Green Bay & Western 2-8-0 "Consolidation" Locomotives in the USA
Class Details by Steve Llanso of Sweat House Media
Class R-2 / C-38 (Locobase 1351)
Data from 1947 diagram reproduced on [
] (accessed 17 June 2003). See the detailed roster at [], last accessed 20 December 2011. Works numbers were 67819-67820 in April 1929.
Drury (1993) comments that unlike earlier 20th-century Consolidations on the GB&W, these engines were well suited to the 70-lb rail. The lower works number represented Kewaunee, Green Bay & Western's #49 (sale price was $34,050) while its younger twin was numbered 69 on the GB&W.
They operated on the Green Bay Routes until November 1950, being renumbered 350-351 in 1936.When they were retired, 351 was sold to the Ahnapee & Western and 350 went to the Consolidated Water Power and Paper Company
