This engine was likely put into service between 1993-1995 when the short-lived "CN North America" logo was used. Today company sports the plain "CN" logo minus the map image. An in depth discussion of the history of CN's logo can be found at Best Logos -- World's Best Logo and Brands blog. I remember seeing the CN logo on engines and rail cars when I was a growing up outside of Detroit, including the ones that spelled out Canadian National Railways in a box back lit by a Maple Leaf.
CN is the largest railway in Canada with 22,000 employees, Incidentally, the firm owns twenty-one thousand miles of rails run from coast to coast including extensive rails in the central United States running all the way to the Gulf of Mexico, according to Wiki. . From time to time there are proposals to link Alaska with the Canadian rail system, which I think would be a fine idea, but the economics don't seem to warrant it.
Thanks for the card and stamps, Glenn.
