CSX Transportation's slogan "How Tomorrow Moves" has become their identity as they adapt to changes in the transportation industry. Stricter environmental regulations require cuts to locomotive emissions, which CSX has met by purchasing new, low-emission locomotives and rebuilding older ones. Coal production and shipping is declining in the US due to environmental emphasis, threatening rail transportation income. However, CSX is increasing shipping of intermodal freight to make up for lost coal volume while providing environmental benefits over trucking. By adapting operations and investing in new technology, CSX lives its slogan of preparing for the future of transportation.
