Journal of Commerce--Shippers shifted freight from all-truck modes to intermodal at the fastest pace in years during the second quarter, according to a closely watched survey by the Wolfe Trahan research group.

Based on preliminary results of the survey conducted in July and early August, the shift from roads to rail occurred more than at any point in the last eight years, the analysts said, and shippers expect to shift more domestic cargo to intermodal in the months ahead. The full results of the survey are scheduled to be released before Labor Day.
