The allocation of revenues between reporting periods is based on the relative transit time in each reporting period with expenses recognized as incurred. Accessorial revenues are recognized at a point in time as performance obligations are satisfied. Freight revenues increased 14% year-over-year to $23.2 billion driven by higher fuel surcharge revenues, core pricing gains, and a 2% increase in volume.

The two key drivers of this metric are the speed of the train between terminals (average train speed) and the time a rail car spends at the terminals (average terminal dwell time). Freight car velocity, average train speed, and average terminal dwell deteriorated compared to 2021 as excess operating car inventory levels and hiring challenges decreased network fluidity.

Locomotive diesel fuel prices, which averaged $3.65 per gallon (including taxes and transportation costs) in 2022, compared to $2.23 per gallon in 2021, increased expenses $1.3 billion (excluding any impact from increased volume year-over-year). Gross ton-miles increased 3% driving higher fuel expense.
Fuel expense decreased compared to 2022 due to a decrease in locomotive diesel fuel prices, which averaged $3.09 per gallon (including taxes and transportation costs) in 2023 compared to $3.65 per gallon in 2022, resulting in a $0.5 billion decrease in expense (excluding any impact from decreased volume year-over-year), and a 1% decrease in gross ton-miles, partially offset by a 1% deterioration to the fuel consumption rate in 2023 (computed as gallons of fuel consumed divided by gross ton-miles).
Interest Expense – Interest expense increased in 2022 compared to 2021 due to an increased weighted-average debt level of $32.1 billion in 2022 from $28.3 billion in 2021, partially offset by a lower effective interest rate of 4.0% in 2022 compared to 4.1% in 2021.
Interest Expense – Interest expense increased in 2023 compared to 2022 due to an increased weighted-average debt level of $33.2 billion in 2023 from $32.1 billion in 2022. The effective interest rate was 4.0% in both periods. Income Tax Expense – Income tax expense decreased in 2023 compared to 2022 due to lower pre-tax income and deferred tax expense reductions.

If the estimated useful lives of all depreciable assets were increased by one year, annual depreciation expense would decrease by approximately $69 million. If the estimated useful lives of all depreciable assets were decreased by one year, annual depreciation expense would increase by approximately $73 million.
If the estimated useful lives of all depreciable assets were decreased by one year, annual depreciation expense would increase by approximately $76 million. We are projecting an increase in our depreciation expense of approximately 3% to 4% in 2024 versus 2023. This is driven by an increase in our projected depreciable asset base .
Other expenses increased 10% in 2022 compared to 2021 driven by casualty expenses, including higher personal injury expense and damaged freight; increased business travel costs; and higher state and local taxes, partially offset by higher equity income.
Other expenses increased 12% in 2023 compared to 2022 driven by casualty expenses, including higher personal injury expense, environmental remediation, and damaged freight, and one-time write-offs.

We could again see volatile fuel prices during 2023, as they are sensitive to global and U.S. domestic demand, refining capacity, geopolitical events, weather conditions, and other factors. As prices fluctuate, there will be a timing impact on earnings, as our fuel surcharge programs trail increases or decreases in fuel price by approximately two months.
Lower coal demand and some lost international intermodal business are expected to negatively impact volume. Fuel prices may continue to fluctuate in the current economic environment. As prices fluctuate, there will be a timing impact on earnings, as our fuel surcharge programs trail increases or decreases in fuel prices by approximately two months.
In 2022, other subsidiary revenues increased compared to 2021 primarily driven by higher fuel surcharge and an increase in automotive parts shipments due to market demand and contract wins at our Loup subsidiary. Accessorial revenues increased in 2022 compared to 2021 driven by increased intermodal accessorial charges tied to global supply chain disruptions.
In 2023, other subsidiary revenues decreased compared to 2022 primarily driven by weaker demand for intermodal shipments at our Loup subsidiary. Accessorial revenues decreased in 2023 compared to 2022 driven by decreased intermodal accessorial and container revenues due to lower volume and improvements in the global supply chain as reflected in better equipment cycle times.

Workforce Productivity – Workforce productivity is average daily car miles per employee. Workforce productivity decreased slightly in 2022, as average daily car miles increased 3% and employees increased 3% compared to 2021. The 3% increase in employee levels was driven by an increase in train, engine, and yard employees to address volume increases and operational inefficiencies due to crew shortages.
Workforce productivity declined 3% in 2023 as average daily car miles decreased slightly and employees increased compared to 2022.
Partially offsetting some of the growth was a decline in petroleum shipments, within the energy and specialized markets commodity line, primarily due to regulatory challenges in Mexico markets. 2022 Industrial Carloads Premium – Premium includes shipments of finished automobiles, automotive parts, and merchandise in intermodal containers, both domestic and international.
