Why were railroads built between Pittsburgh Pennsylvania and Duluth Minnesota from W?

Answer 1

Railroads were built between Pittsburgh, Pennsylvania, and Duluth, Minnesota, primarily to facilitate the transportation of iron ore and other raw materials essential for the steel industry. Pittsburgh was a major steel production hub, while Duluth served as a key shipping port on Lake Superior, allowing for the efficient movement of resources. The railroads connected these regions, promoting economic growth and enabling the rapid expansion of industrial activities in the late 19th and early 20th centuries. This infrastructure also supported the broader development of the American Midwest and its industries.
