CN 6400

thanks, Traj!

 The mid 1930s was the time of the streamlined steam locomotive. In the US, among others, NYC had their Henry Dreyfus-designed Hudsons, Pennsylvania RR their Raymond Loewy K4s and Milwaukee Road, the Hiawathas. In Canada both the CPR and CNR were experimenting with their versions.
The Canadian National Railway 6400 was the result of wind tunnel testing at the National Research Council and there were five of these built built for CNR, designated the U4A class. Intended for high speed passenger service in Ontario and Quebec they were used till the end of steam. 
There were also six built to the same design by Lima for the Grand Trunk Western, designation U4B. 
 Canada did better than their American counterparts in preserving their streamlined locomotives, 6400 survived and is on display at the Museum of Science and Technology in Ottawa.
