Caption: A Carl Bury image. In September 1975 the Brantford resident did a driving trip to the western provinces. One of his classic discoveries was CN's first SD40 resting between road trips at Jasper AB, already showing signs of heavy use after 8 years of age. Make no mistake, this is THE unit of the class. Unfortunately, having lasted until Dec2006 on the active roster, she met the torch at Lac La Biche AB during June2007 after efforts for preservation fell short.
