Canadian National 4-6-4 No. 5701 pauses at the depot in Kitchener, Ontario at an unknown date in the 1950s. The transparency, ascribed to Walter Taylor, comes to this Collection courtesy of Tom Rock of T.D.R. Productions. Erected in 1930 by Montreal Locomotive Works, locomotives of the K-5-a class featured 23x28-inch cylinders and a boiler pressure of 275 p.s.i. They had a locomotive weight of 356,400 pounds and exerted a tractive force of 43,000 pounds (53,300 with booster in operation). Their 74 square feet of grate area, 3377 square feet of evaporative heating surface and 1465 square feet of superheater surface helped make them the speedsters they were in premium CNR passenger service before the arrival of diesels.
