Transportation titan Norfolk Southern is the one big train that could. Its main subsidiary, Norfolk Southern Railway, transports freight over a network consisting of about 20,000 route miles in 20-plus states in the eastern, southeastern, and Midwestern US and in Ontario and Quebec. The rail system is made up of more than 15,000 route miles owned by Norfolk Southern and nearly 5,000 route miles of trackage rights, which allow the company to use tracks owned by other railroads. Norfolk Southern transports coal and general merchandise, including automotive products and chemicals. In late 2015, the company rejected an unsolicited takeover by Canadian Pacific in a deal worth $37.8 billion.
