Ontario Northland 1737 - a 3000 hp General Motors SD40-2 built in 1974 at London, Ontario and seen at Dartmouth, Nova Scotia on 5 February 1998. This loco was on loan to CN as a payback of horsepower-hours used by ON when CN locomotives hauled ON trains. There are no dynamic brakes. More photos at our home pages.
