Freight revenues decreased 3% year-over-year to $22.6 billion driven by lower fuel surcharge revenues, negative mix of traffic (decreased lumber shipments and increased short haul rock shipments), and a 1% decrease in volume, partially offset by core pricing gains. Volume decreases were primarily driven by weaker demand for intermodal and coal shipments.

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 improved compared to 2022 as last year we experienced congestion across our system.
