High-quality low-poly model of a 660hp MLW/Alco S3 diesel/electric switcher as used by Canadian Pacific. This particular locomotive is part of the Schreiber Ontario Rail Museum, and is typical of the vast number of these S3 switcher units used by railroads in North America since the fifties. Many are still in use. Canadian Pacific, in particular, purchased and operated more S3 units than any Class-1 railroad in the world.
The model has a 2048x2048 main texture (which may be reduced) and 32-bit alphas for windows. All textures are in TGA format.
