Comments on: CN once had a decent variety of six axle cowl units, by the late 1990’s the small fleet of Bombardier HR616’s were gone. Then the 2000’s would claim the somewhat troublesome SD50F’s. The SD60F fleet along with the handful of demonstrator SD50AF’s would soldier on through the 2010’s until being displaced by a large group of second hand standard cab ex Oakway SD60’s. This would leave CN’s Dash-8 cowls as the last Drapers on the roster until their retirement. The four demonstrator SD50AF’s 5500-5503 were unique as they were basically SD60F’s internally in a SD50F body. This day SD50AF 5503 was leading train 382 along with an IC SD70. By this time 5503 was running short on years remaining on CN’s roster and showing its age with damaged grills, replacement hood door and a good coat of weathering. Today the CN’s variety of cowls is certainly missed by railfans. http://www.railpictures.ca The BEST Canadian photos on the Internet, eh?
