Executive Vice President of Sales and Marketing at CSX
Thank you, Jim. Turning to slide 5. Third quarter revenue increased 24% year-over-year. With growth across all major lines of business, the inclusion of Quality Carriers revenue represented roughly 8 percentage points of the total increase. Supply chain challenges including a lack of labor and equipment continue to impact almost every market we serve, driving volatility and freight flows, and uneven volumes. Merchandise revenue increased 6% on 2% lower volumes, as higher revenue across all other markets was offset by declines in auto, driven by the ongoing semiconductor shortages.
The industrial in construction-related markets such as metals and equipment, forest products and minerals, all showed strong year-over-year volume growth. In addition, our core chemicals business grew but was partially offset by declines in crude oil and other energy-related markets.
Intermodal revenue increased 14% on 4% higher volumes, due to increased international shipments as a result of strong demand. Inventory replenishment and growth in rail volumes of East Coast ports. The domestic side was more challenged, as a multiple supply side constraints including container and chassis shortages have resulted in inability to meet the strong demand.
Coal revenue increased 39% on 16% higher volumes, with growth across all end-markets. Domestic coal benefited from higher utility and industrial demand, and export coal revenue increased from the combination of higher demand and higher export benchmark prices. Other revenue increased primarily due to higher Intermodal storage and equipment usage due to the broader supply chain disruptions from truck driver shortages, chassis availability, and the lack of warehouse capacity.
Turning to Slide 6. This is an extraordinary time, as customers and global supply-chain face challenges we have never experienced before. On trucks to chassis, supports to containers, lack of truck drivers to labor challenges at the warehouse and production facilities, we are seeing shortages everywhere. The entire CSX team has been highly focused on delivering new, innovative solutions and partnering with customers to address the supply-chain challenges by driving more volume to the railroad.
Across the network, we have accelerated investments to create new capacity. To address the truck driver shortages, we have added 13 new overflow container yards, implemented new steel-wheel options for West Coast cargo, and added TRANSFLO sites, that offer customers additional options to move their freight at a lower cost.
To address the port congestion in container shortages, we have added new solutions to accelerate repositioning of containers and utilized port-to-port lanes to alleviate marine terminal congestion. We are working closely with partners, including GPA to utilize additional inland rail yards to help reduce congestion at the port.
We have also been aggressively expanding our customer solutions team to further supplement the significant investments we are making in customer-facing technology. Our team is working diligently to create new solutions and options for shippers with supply chain disruptions unlikely to improve in the near term.
Finally, we are starting to see early signs of customers making long-term investment decisions to reinvest in onshore production and supply chain solutions. To address these customer needs, we continue to develop and invest in new CSX select sites that offer shovel-ready CSX served solution to meet customer requirements.
With that, I will hand it over to Jamie to discuss operations.
