K-5-a 4-6-4 Hudson

Only five of these Hudsons were owned by the CNR unlike the competition (CPR) which had 65, the second largest fleet in North America after the New York Central. Built especially for the very competitive Montreal-Toronto passenger service these engines performed well with short trains however, when traffic grew beyond nine cars they could not handle the fast schedule required. They were replaced by Northern 4-8-4's and re-assigned to Toronto-London-Sarnia/Windsor service.

Cylinders 23" x 28" Drivers 80" Boiler pressure 275 lbs. 43,000 tractive effort (53,300 with booster)
Equipped with Baker valve gear, popular on CNR. 14,000 gallon (18 ton) tender was the largest on the CNR system.
Locomotives (engine and tender) weighed 330 tons in working order.

These two views of a spotless 5704 are proof that these Hudsons were the finest looking steam locomotives in Canada.
