The B&O Railroad, or Baltimore and Ohio Railroad, was one of the first railroads in the United States, established in 1827. It was created to provide a transportation link between the eastern cities and the western frontier, facilitating trade and travel. The railroad played a significant role in the economic development of the nation, particularly in the Mid-Atlantic region. The B&O Railroad was known for its innovative approaches, including the use of steam locomotives and the construction of the first long-distance passenger train service. Over the years, it expanded its network, connecting major cities and contributing to the growth of the American railroad industry. The B&O eventually became part of the CSX Transportation system in 1980.
