Operating supplies and expenses increased $45.1 million, or 31.3%, in third-quarter 2026 and $77.2 million, or 17.7%, in the first nine months, primarily because of higher diesel fuel costs. The average cost per gallon of diesel fuel, excluding fuel taxes, increased 68.4% in the quarter and 50.8% in the nine-month period versus 2025. Gallons consumed fell 0.3% and 5.0%, respectively, primarily because fewer miles were driven.
