Chirago, Burlington and Quincy Railroad Company

Chirago, Burlington and Quincy Railroad Company - The Baltimore and Ohio Railroad, based in Baltimore, Maryland, was one of the two or three oldest, largest, most important railroads in the history of the mid-Atlantic region. Its great rival was the Pennsylvania Railroad. The B&O was the first Class I railroad in the U.S. as well as one of the first in the nation. During its peak years, the railroad carried coal, steel, and other freight, as well as passengers, as far North as New York City, and as far west as Chicago. Most surviving trackage is operated by CSX Transportation. The B&O provided critical logistic support to the Union during the Civil War, when it was the target of repeated Confederate raids.
