US forest products volume in the week was up 2.8%, Canada was 1% higher and Mexico rose 14.9%.
Total North American rail carloads in the week climbed 6.7% and were 2.4% higher year-to-date. Grain was 18.1% higher in the week and petroleum rose 14.6%, AAR showed.
Seventeen of the 20 commodity categories tracked by the AAR each month saw year-over-year carload increases in June, the same as May, AAR commented. Commodities with the biggest carload increases in June 2014 over June 2013 included crushed stone, sand and gravel, up 14.1%, grain, up 16.5%, and petroleum and petroleum products, up 8.6%.
"All in all, June was another good month for rail traffic," said AAR. "The fact that most categories of rail traffic were up in June, and that intermodal set a new volume record, supports the view that the economy is rebounding at a decent pace. Railroads will continue to do their part in ensuring this continues."
