CSX Corporation's Q2 earnings report showed a 2% decrease in earnings per share and a 3.01% decrease in sales compared to the same period last year. The company attributed the revenue decline to lower fuel recovery, pricing declines in export coal, and lower intermodal volume. However, gains in merchandise pricing and volume, as well as higher coal volumes, helped offset these decreases. Despite the mixed results, CSX shares fell by 3.95% in after-hours trading.
