identification and that of its new corporate cousins, the Illinois Central Railroad (acquired by CN in 1999) and Wisconsin Central Ltd. (acquired by CN in 2001), are referred-to with CN's name and corporate image. However, while each railroad's locomotives would eventually receive CN's logo and black, red-orange and white paint scheme, they would still retain their respective reporting marks. Despite the corporate re-branding, GTW's blue color scheme and its logo would persist on rolling stock and locomotives for several years while they were slowly either repainted or retired. CN also reintegrated managerial and some operational control of GTW, as it would gradually shift out of Detroit and into CN headquarters in Montreal. GTW would continue to maintain some office and dispatching functions from offices in suburban Troy, Michigan. All the routes that make up GTW are part of CN's Midwest Division in its Michigan Zone. Grand Trunk Corporation, now formally headquartered at CN in Montreal, is the holding company for almost all of CN's U.S. properties, which include Grand Trunk Western, Illinois Central, Wisconsin Central, Duluth, Winnipeg & Pacific and Great Lakes Transportation, which includes the Bessemer & Lake Erie Railroad and the Duluth, Missabe and Iron Range Railway. The Association of American Railroads has considered the Grand Trunk Corporation as a single, non-operating Class I Railroad since 2002. Grand Trunk Western still exists as a corporate entity, but can now be considered a company on paper. CN refers to GTW's routes and operations in its corporate communications as the former Grand Trunk Western territory. Locomotives Steam Grand Trunk Western was one of the last U.S. railroads to employ steam locomotives. It ran the last scheduled steam passenger train in the United States on March 27, 1960, on its train #21 from Detroit's Brush Street Station north to Durand Union Station. The run drew thousands of rail enthusiasts. With 3,600 passengers holding tickets, train #21 had to be run in two sections (as two separate trains) to accommodate the excess of passengers. GTW U-3-b class Northern-type locomotive 6319 led the first section of train #21 with 15 passenger cars, and GTW Northern 6322 pulled the second section with 22 passenger cars. Steam was used on some freight trains until 1961. GTW's predecessor lines primarily used American-type locomotives before the turn of the 20th century. Throughout its history, GTW has shared the same type and class designations of its locomotives with
