Description
Prototype Information:
The SD50Fs were built by General Motors Diesel Division (GMDD) in London, Ontario, Canada in two batches – in 1985 and 1987, respectively. It is the Canadian variant of the EMD SD50 six-axle diesel-electric freight locomotive. Nicknamed the ‘Draper Taper’ after CN’s Chief of Motive Power at the time, it has a full-width cowl body and cab, with a tapered section immediately behind the cab for improved rear visibility. A total of 60 units were built, all for the Canadian National Railway. They saw extensive mainline freight service on the CN network across Canada and in the United States. They were retired by CN in 2008. A limited number of locomotives still operate today with second-hand owners.
