The Erie Railroad was a major American railroad that operated primarily in the northeastern United States. Founded in 1832, it played a crucial role in connecting the Great Lakes with the Atlantic Ocean, facilitating trade and transportation. The railroad expanded over the years, reaching key cities like New York City and Chicago. In the late 19th and early 20th centuries, the Erie Railroad became known for its innovative services and extensive network. It faced financial difficulties during the Great Depression but continued to operate until it merged with the Lackawanna Railroad in 1960, forming the Erie-Lackawanna Railroad.
