Railroad Short Name: CN
The SD50AFs were built General Motors Diesel Division (GMDD) in London, Ontario, Canada in 1985. They were effectively ‘demonstrator’ SD60F units with the then-new 710 prime mover installed in place of the 645 used on the SD50 series. A total of 4 units were built for the Canadian National Railway. Initially numbered CN 9900-9903, they were renumbered to CN 5500-5503 by 1989. All 4 units were retired by CN in 2017.
