U.S. rail intermodal traffic rose 1.9% last week over the same week a year ago, the Association of American Railroads said.
Container traffic for the week ended Saturday rose 4% to 218,826 units, while trailer traffic fell 10.9% to 30,705 units, AAR said.
Railroad carloads — excluding intermodal — fell 5.4% to 283,414 units for the week, AAR said in its weekly report.
Railroad volume is considered an important economic indicator. Intermodal traffic, which tends to be higher-valued merchandise than bulk commodities, uses trains for the longhaul and trucks for the shorter distance at either end of the trip.
