Caption: CN Toronto to London passenger train 75 with Hudson 5702 crosses Cooksville Creek at Mile 11.8, on the Oakville Sub in 1957. While competitor Canadian Pacific had a healthy fleet of 4-6-4 Hudson steamers, Canadian National only had 5: CN 5700-5704, K5a class units built by MLW in 1930. 5702 and her sisters were used in passenger service out of Toronto's Spadina Roundhouse until the end of steam, and today 5702 can be found on display at the Canadian Railway Museum (Exporail) in St. Constant, QC. Sister 5703 (as 5700) is at the Elgin County Ry Museum in St. Thomas ON.
