The 2016 headlines were pretty grim. Looking at data from the Intermodal Association of North America, IPI revenue movements of 20-, 40-, and 45-foot intermodal containers across North America dropped 3.3 percent from 2015. Meanwhile, containerized imports entering the United States and western Canada, measured in 20-foot-equivalent units (TEUs), rose 3.0 percent and total TEUs traversing the ports, including import and export volumes, rose 2.0 percent. Had IPI movements kept pace with the increase in total import-export activity rather than dropping, there would have been almost a half-million more revenue movements of intermodal containers in 2016 — more than 1,300 per day.
A more detailed look at which corridors gained and lost volume from 2015 to 2016 provides some insight. Total IPI volume dropped 288,000 units over that time. Those lanes that registered declining volumes accounted for a loss of 424,000 revenue moves. But these losses were partially offset by other corridors that showed gains of 136,000 revenue moves.
The accompanying chart displays the major winners and losers in terms of the IANA region-to-region flows. The biggest loser by far was the South Central-Southwest corridor, mainly California-Texas. This corridor alone accounted for 38 percent of all losses. It’s followed by other predominantly West Coast-oriented lanes.
