Kansas City Southern, the smallest Class I railroad, derives half its $1.8 billion revenue on 3,200 miles of track in the central and southern U.S. Remaining sales are produced by operating long-term concessions on 2,700 miles of rail in Mexico and 47 miles of track adjacent to the Panama Canal. KCS hauls a diverse mix of freight, including agricultural and food (20% of total revenue), chemicals (19%), forest products (13%), coal (11%), intermodal (9%), and automobiles (6%).
