of the Detroit and Toledo Shore Line Railroad, in 1981. GTW management found it cost-effective to lease or purchase second-hand diesel locomotives. It purchased several former Rock Island GP38-2s after that railroad closed in 1980. Union Pacific sold GTW several surplus former Missouri Pacific SD40-2s after it had acquired that railroad. It was also common for GTW and CN to share steam and diesel locomotives when either of them was in need of extra motive power. GTW also sent diesel locomotives for use to its fellow GTC subsidiary railways Central Vermont and Duluth, Winnipeg and Pacific. , many GTW GP38s still wore their original blue, red/orange and white paint scheme and were found operating throughout CN's other US subsidiaries. However, since 1991, CN gradually retired, sold or applied its own paint scheme to GTW locomotives. , the last GTW-painted SD40-2, 5936, was still operated by CN. Facilities Over its history, Grand Trunk Western has had rail yards and engine terminals located in Detroit, Battle Creek, Durand, Flat Rock, Flint, Grand Rapids, Pontiac, Port Huron, Blue Island, Illinois and Chicago. In each of these cities, GTW had engine terminals and facilities for locomotive maintenance, including roundhouses and turntables. Prior to 1910, the railroad constructed its major locomotive repair shops in Battle Creek, while railcar repair and maintenance was handled by GTW's Port Huron car shops. Its major freight yards were Durand Yard and Pontiac Yard, located in the two Michigan cities that were major GTW junction points. There is also Nichols Yard in Battle Creek, Tunnel Yard in Port Huron, Torrey Yard near Flint and East Yard near the Milwaukee Junction area in the Detroit enclave of Hamtramck. City Yard was the railroad's rail yard on the Detroit riverfront adjacent to Brush Street Station and its ferry slip dock. The yard, dock and station were eventually all removed and redeveloped by 1975 for construction of the Renaissance Center. It also obtained the former Penn Central Winona Yard in Bay City when it acquired that trackage from Conrail, in 1976. On Chicago's south side, GTW's Elsdon Yard served as its primary yard and locomotive facility there since the railroad laid tracks into the city in the 1880s. GTW also had a smaller transfer yard south of Chicago near rail junction Blue Island, Illinois. In 1975, GTW opened an intermodal freight terminal yard in Chicago known as Railport. The facility is in Chicago's
