The Kansas City Southern Railway Company , owned by Kansas City Southern, is the smallest and third-oldest Class I railroad in North America (just behind Union Pacific Railroad and Canadian Pacific Railway) still in operation. KCS was founded in 1887 and is currently operating in a region consisting of ten central U.S. states. KCS also owns and indirectly operates Kansas City Southern de México (KCSM) in the central and northeastern states of México, and is the only Class I Railroad to own any track both inside and outside of Mexico's boundaries (Ferromex is the only other Class I operating in Mexico). Including all trackage owned by wholly owned subsidiaries, KCS owns a total of approximately 9,600 kilometers (6,000 route miles) of track.
