Rail freight gains ride steelmaking, energy sectors
U.S. rail traffic rose 4.1% week-over-week (week ending Aug 29, 2026), with intermodal up 5.7% y/y; truck rates are climbing again as federal enforcement cuts carrier capacity, narrowing the 34% truck-to-rail rate gap. Motor vehicle and parts shipments dropped 6%, signaling uneven manufacturing supply chains.
Trucking capacity tightening from federal enforcement is a structural shift, not seasonal — sellers relying on spot freight for Q4 inventory movement face margin compression right before peak.
Rising truck rates directly compress inbound freight costs for sellers importing or moving bulk inventory domestically — if your 3PL or freight broker uses spot truck rates, expect quotes to tick up in Q4. Lock in contracted rates now before the seasonal freight surge compounds enforcement-driven capacity losses.
Operational Impact
This story may require teams to revisit workflows, monitoring, or platform assumptions.
Bottom Line
Rising truck rates plus tight capacity means Q4 inbound freight costs are going up.

Full Coverage
Rail traffic on U. S. carriers totaled 543,212 carloads and intermodal units, up 4. 1% from the same week a year ago, according to the Association of American Railroads. For the week ending August 29, commodity freight came to 240,021 carloads, better by 2. 2%, while intermodal volume was 303,191 containers and trailers, ahead 5. 7% y/y.
Seven of 10 carload commodity group shipments tracked by AAR increased from the same week in 2025. They were led by metallic ores and metals typically used in steelmaking, 11%; petroleum and related products, 8. 4%; and grain, 8. 3%.
Watch Bill Stephens of Trains and Stuart Chirls of FreightWaves analyze the rail and intermodal markets, exclusively on the latest FreightWaves / TrainsPRO Monthly Rail Report. Decreases were seen in chemicals, 3. 8%, and motor vehicles and parts, 6%.
Analysts have speculated that steel production for data center construction is likely boosting shipments of metallic ore, while uneven manufacturing output has produced off-and-on results in chemicals. Intermodal continues to benefit from the wide delta between truck and rail rates, now at around 34%, according to SONAR data.
A pause in rising truck rates appears to be over as tender acceptance rates are again climbing amid continued federal enforcement actions that have culled capacity. Coal volumes were up 1. 9% y/y, both on the seasonal runup to winter but also on increasing use by power generators amid greater demand and pro-coal support from the Trump administration.
(Chart: AAR) For the first 34 weeks of 2026, U. S. railroads reported cumulative volume of 7,751,931 carloads, up 2. 7%, and 9,605,177 intermodal units, up 3. 9%, y/y. Total combined traffic 17,357,108 carloads and intermodal units, a healthy 3. 3% gain from 2025. North American rail volume for the week on nine U. S.
, Canadian and Mexican railroads improved by 1. 7% to 346,191 carloads, and 395,417 intermodal units, up 6% y/y. Total combined traffic was 741,608 carloads and intermodal units, an increase of 3. 9%. North American volume for the first 34 weeks of 2026 was 23,812,940 carloads and intermodal units, ahead 3% on 2025.
