BNSF, CPKC, and CSX to request broad access to a combined UP
BNSF, CPKC, and CSX plan to request extensive trackage rights over a combined Union Pacific-Norfolk Southern system, if regulators approve their $85 billion merger. The railroads argue the merger will harm competition and the economy. BNSF seeks 824 miles of trackage rights between Chicago and Pennsylvania, while CPKC targets the Kansas City-St. Louis corridor and other routes. CSX also aims for access to the Kansas City-St. Louis trackage.
