The National Limited was the premier train of the Baltimore and Ohio Railroad (B&O) on its route between Jersey City, New Jersey and St. Louis, Missouri, with major station stops in Washington, D.C., and Cincinnati, Ohio. It operated from 1925 to 1971. For much of its life it offered exclusive all-Pullman service, and it was the first long-distance train to be entirely air-conditioned. The National Limited was one of many trains discontinued when Amtrak began operations on May 1, 1971. Amtrak revived the name for another New York–St. Louis service which did not use the B&O route.

The Central Railroad of New Jersey Terminal, also known as Communipaw Terminal and Jersey City Terminal, was the Central Railroad of New Jersey's waterfront passenger terminal in Jersey City, New Jersey. The terminal was built in 1889, replacing an earlier one that had been in use since 1864. It operated until April 30, 1967.
