Adirondack and St. Lawrence Railroad

Also known as the Mohawk and Malone Railway, the Adirondack and St. Lawrence Railroad was built by Dr. William Seward Webb. The line crossed the northern Adirondacks at Tupper Lake Junction, just north of Tupper Lake. Webb began by purchasing the narrow gauge Herkimer, Newport and Poland Railroad, which ran 16 miles from Herkimer to Poland. He then had track built from Tupper Lake to Moira and thence to Montreal. This was variously called the Adirondack and St. Lawrence Railroad and the Mohawk and Malone Railway. It opened in 1892 from Malone Junction to Childwold Station with a branch from Lake Clear Junction to Saranac Lake. After 1893, it was controlled by the New York Central and Hudson River Railroad, and in 1913, it merged with the Central as the "Adirondack Division".

Detroit and Chicago Railroad (original)

Detroit, Monroe and Toledo Railroad (original) Chartered in 1855, the Detroit, Monroe and Toledo Railroad (DM&T) ran from Detroit, Michigan, south-southwest along the shore of Lake Erie to Monroe, Michigan. It crossed the state line into Ohio, where it ran into Toledo, Ohio. The line was completed on December 25, 1856. The DM&T leased itself in perpetuity to the Michigan Southern and Northern Indiana Railroad (MS&NI) on July 1, 1856. The MS&NI merged with the Lake Shore Railway in 1869 to form the Lake Shore and Michigan Southern Railway (LS&MS). The New York Central and Hudson River Railroad achieved a controlling interest in the LS&MS in 1877, and the two companies merged in 1914 to form the New York Central Railroad. The DM&T's assets were merged into the NYC on January 1, 1915.
