The Baltimore and Ohio Railroad (B&O) was one of the oldest railroads in the United States, with an original line from the port of Baltimore, Maryland, west to the Ohio River at Wheeling and Parkersburg, West Virginia. It is now part of the CSX network, and includes the oldest operational railroad bridge in the world. The B&O also included the Leiper Railroad, the first permanent railroad in the U.S. In later years, B&O advertising carried the motto: "Linking 13 Great States with the Nation.".
