CSX is seeing early signs of freight volumes improving in the fourth quarter. Chief Commercial Officer Kevin Boone says on a call with analysts that most of the rail operator’s markets are improving sequentially, based on October volume trends so far. Agricultural and food products and forest products saw the biggest drop in shipments in the third-quarter as overall volumes are flat year-on-year. While mills, which produce wood products, are still taking downtime, Boone sees improvements in food in the fourth quarter as the Midwest harvest boosts volumes.
