Railroad Acts refer to a series of legislative measures enacted primarily in the 19th century that aimed to promote the construction and expansion of railroads across the United States. These acts were crucial in facilitating industrial growth and urbanization by providing federal land grants, financial incentives, and regulatory frameworks that encouraged private investment in rail infrastructure. The establishment of railroads transformed transportation, enabled the movement of goods and people, and played a key role in shaping the economic landscape during a time of rapid industrial development.
