If something has ever tempted me to switch scale and guage, then this is it.
Its a shame that they never worked on the White Pass and Yukon proper. The railway closed in October 1982 before they could be delivered. Stored for years, 3 wound up working for US gypsum in Plaster City, CA (112, 113 in 1991 and later 111 as a wreck replacement for 113)
Finally in 1994, 114 was sent to work on the WP&Y (now solely a tourist line) and has been there since.
Would be an interesting "what if" to have a 1980s WP&Y survive with a fleet of these along with the Alcos and GEs.
