Canadian Pacific Hudson No. 2818 is captured on film in Windsor, Ontario by an anonymous photographer probably around 1950, in an image provided by Tom Rock of T.D.R. Productions. No. 2828 belonged to class H1b, ten locomotives delivered in 1930 by Montreal Locomotive Works. With 75-inch drivers, these engines developed a tractive effort of 45,300 pounds. They had 22x30-inch cylinders and carried 275 pounds of boiler pressure. Their steaming capacity stemmed from an 81-square-foot grate area, together with an evaporative heating surface of 3791 square feet augmented with 1542 square feet of superheater surface. Like all newer Canadian steam locomotives and many built for railroads in the northern United States, No. 2818 had an all-weather vestibule cab providing greater protection for the engine crew during the colder seasons. Sister locomotive No. 2816 survives, restored to operation and providing public relations for the Canadian Pacific system as the "CPR Empress".
