WASHINGTON — Rail traffic for the week ending Jan. 15 continued its upward climb, reports the Association of American Railroads.

Carloads were up by 7.5 percent compared with the same week in 2010, and intermodal (trailers and containers on flat cars) showed a gain of 5.8 percent over the same week in 2010.

The AAR reported that for the first two weeks of 2011, U.S. railroads reported an increase of 13.5 percent in carloads and 7.2 percent in intermodal.

Rail traffic continued its torrid growth the first week of 2011, with the Association of American Railroads (AAR) reporting freight carloadings were up more than 20 percent versus the same week in 2010, and intermodal (trailers and containers on flat cars) were up almost 9 percent from the first week of 2010.

This comes on the heels of a banner year for freight railroads in 2010. The AAR said the combined increase in total annual carloads and intermodal in 2010 was equivalent to some 20,000 additional trains moving when compared with 2009.

It was one a pretty good year in 2010 for freight railroads.

Although freight volume trailed pre-recession 2008 figures, the nation’s major railroads reported a healthy 7.3 percent jump in carload traffic and a 14.2 percent increase in intermodal (trailers and containers on flat cars).

AAR officials called the 52-week figures “a positive development.”

Carload traffic remains about 10 percent below pre-recession levels, but its rate of growth continues to increase.

U.S. Class I railroad traffic continued its growth trend through the Christmas holiday week, reports the Association of American Railroads.

Carloads were up almost 30 percent versus the same holiday week in 2009, and intermodal (trailers and containers on flat cars) was up more than 25 percent versus the same holiday week in 2009.

The AAR reported that for the first 51 weeks of 2010, carloads are up more than 7 percent and intermodal is up more than 14 percent over the first 51 weeks of 2009.

Shippers are increasingly abandoning all-truck movements for their freight in favor of rail intermodal (trailers and containers atop rail flat cars), reports the Journal of Commerce.

Journal of Commerce trucking editor Bill Cassidy writes, “Supermarkets and shopping malls don’t have rail sidings, truckers love to point out, but the intermodal industry is moving steadily closer to the store floor.”

Increased investments in improved port transfers and the growing fleet of 53-foot long domestic containers are creating what shippers call more “seamless” transportation — hence the move to intermodal, says the Journal of Commerce.

The Association of American Railroads reported last week that through the first 46 weeks of 2010, total intermodal loads are up 14.8 percent over a similar period in 2009. 

The Association of American Railroads reports that through the first 46 weeks of 2010, total intermodal loads (trailers and containers atop rail flat cars) are up 14.8 percent over a similar period in 2009.

Intermodal loads on Class I railroads doubled from some 6 million in 1990 to more than 12 million in 2007. Although the economic downturn saw intermodal loads retreat to fewer than 10 million in 2009, they have resumed their upward climb, according to AAR statistics.

Rail freight loadings continue to show improvement, reports the AAR in releasing carloading data for the week ending Oct. 16.

Total U.S. carloadings increased by more than 10 percent over the same week in 2009.

Intermodal loadings were up by more than 15 percent over the comparable week in 2009.

Fourteen of the 19 carload commodity groups increased from the comparable week in 2009.

For the first 41 weeks of 2010, U.S. railroads carloadings are up more than 7 percent over the first 41 weeks in 2009; and intermodal loadings are up almost 15 percent.
