Kansas City Southern, the smallest Class I railroad, derives about half of its $2.6 billion revenue on 3,400 miles of track in the Central and Southern United States. Remaining sales are produced by operating concessions on 3,300 miles of rail in Mexico and 47 miles of track adjacent to the Panama Canal. KCS' freight includes industrial and forest products (around 21% of total revenue), chemicals and petroleum (26%), agriculture and minerals (18%), intermodal (13%), energy (9%), and autos (9%); other revenue stems from switching, demurrage, and the like.
