The locomotive served as a demonstrator for GMD, bearing number #275, between 1960 and 1962, including a period in Egypt, but no sales resulted.cite web

After nearly 30 years of service, it was sold in 1992 to the South Simcoe Railway, a heritage museum railway, in Tottenham, Ontario, but in 1995 it was declared surplus to requirements by the railway's directors. After a fund-raising effort, the Southern Michigan Railroad Society purchased the locomotive in 1996, where it remains in operable condition as of 2006. [cite web
