The first-quarter results, including a 2.5% increase in international traffic, showed that volume reached 3.41 million shipments, according to the Intermodal Association of North America's Intermodal Market Trends & Statistics report. Intermodal growth continues even as volume has slumped in other modes of transportation. The 1.1% first quarter 2007 growth rate exceeded the 0.6% increase during the fourth quarter of last year.

The quarterly report, which contains detailed, exclusive market information, included increases in three of the nine IANA regions, including the Southwest and Midwest, which together accounted for 50% of total volume.
