CALVERTON, MD, November 5, 2015 — Despite month-to-month variations, Q3 intermodal growth of 3.4 percent was in line with year-to-date results, according to the Intermodal Association of North America’s third quarter Intermodal Market Trends and Statistics report. The international market segment showed some volatility as its volumes climbed 3.3 percent in July and 6.4 percent in August, then slowed to 1.6 percent growth in September. Nevertheless, the segment closed the quarter with a 4 percent increase, almost even with the 4.1 percent growth in domestic containers.

“The international market segment normalized this quarter after dealing with the lingering effects of Q1 port congestion that were still felt during the second quarter,” said Joni Casey, president and CEO of IANA. “Overall we are seeing international container trends approaching pre-recession levels and domestic volume gains returning to numbers that are comparable to international.”

2015 Intermodal Volumes

The domestic trailer market segment shrunk 3.1 percent in a quarter-over-quarter comparison, making Q3 the fifth consecutive quarter of dipping trailer volumes. This deflated the quarterly gains realized in total intermodal loads. However, September domestic container growth of 6 percent helped boost overall domestic numbers.

The seven highest-density trade corridors, accounting for 66 percent of total intermodal volume, rose 3.7 percent this quarter, exceeding the industry average. Growth rates for each individual corridor varied widely. The intra-Southeast corridor, positively affected by stronger imports and rising market share over trucking, experienced gains of over 20 percent. Meanwhile, the South Central-Southwest corridor volumes decreased by 5.9 percent, with international particularly affected.

Regional traffic growth was overall positive in Q3, despite significant losses in the South Central region and slight declines in Western Canada. The South Central area’s 9.2 percent decline is largely the result of a fall in international shipments. The Northwest and Southeast regions countered with substantial volume increases in Q3, rising 9.9 and 9.1 percent, respectively.
