"Our network serves nearly two-thirds of the nation's population and is well-positioned to capture a significant share of the domestic intermodal market opportunity, estimated at about nine million total loads in the eastern United States," Eliasson said. "Investments in expanded capacity will help convert this long-run opportunity, building on about 30 percent growth in our intermodal business during the past three years."

CSX shipped 2.5 million intermodal containers in 2012, with 90 percent of that traffic in double-stacked service. The company continues to invest in capital projects to expand its intermodal network, which will further increase double-stacked corridors by 2015 with hubs aligned with major ports and population centers.
