RailWorks - Canadian National Wide Nose

The EMD SD40-2W is a Canadian-market version of the SD40-2 diesel-electric locomotive, built for the Canadian National Railway by the Diesel Division of General Motors of Canada Ltd. (formerly General Motors Diesel) of London, Ontario. A total of 123 were constructed between May 1975 and December 1980. The major difference between the SD40-2W and a regular SD40-2 is the fitment of a wide-nose Canadian comfort cab, denoted by the W in the model name.

The Canadian comfort cab or wide cab is a broad-nosed cab design found on several diesel locomotive types. It occupies the entire width of the locomotive, and typically has an access door on the front.
