Northern No. 6333 of the Grand Trunk Western heads a manifest freight at Durand, Michigan, in David V. Leonard's June 6, 1958 photograph. These class U-3-b 4-8-4s had an 84-square-foot grate area, with 4400 square feet of evaporative heating surface and 1955 square feet of superheater surface, all of which rendered them able to steam freely with both passenger and freight trains over the GTW's undulating Michigan profile. Most were equipped with the cast steel pilot with recessed drop coupler, as shown here. At the end of their careers, displaced on the main line by diesels, these fine locomotives were reduced to suburban or local service between Detroit and Durand and can be viewed in the Herron video/DVD Glory Machines of the Grand Trunk Western. There are two survivors of the class, No. 6323 displayed at the Illinois Railway Museum and No. 6325, in operating condition, at the Age of Steam Roundhouse in Ohio.
