In the second quarter of 2007, CSX reported strong financial results with record revenues of $2.53 billion, up 5% from the previous year. Comparable earnings per share increased 22% to $0.71 compared to $0.58 in the prior year. Surface transportation operating income was up 16% to $603 million, driven by pricing gains and productivity improvements that helped lower the operating ratio to 76.2%, a 2.4 point improvement over 2006. Revenues and operating income increased despite declines in certain markets, demonstrating the company's ability to leverage pricing strength and offset volume weakness.
