The Association of American Railroads (AAR) reports carload traffic in May 2011 increased 0.5 percent compared with the same month last year (essentially flat), and intermodal traffic (using intermodal or shipping containers) increased 7.5 percent compared with May 2010.

On the carload side, May 2011 was not especially impressive, following a not especially impressive April. U.S. freight railroads originated 1,159,328 carloads in May, an average of 289,832 per week. That’s up 0.5% (5,960 carloads for the month) on a seasonally unadjusted basis over May 2010, though it was up 16.4% (163,308 carloads) over May 2009.

This graph shows U.S. average weekly rail carloads (NSA).

As the first graph shows, rail carload traffic collapsed in November 2008, and now, 2 years into the recovery, carload traffic has only recovered about half way. From AAR:

For the year to date through May, total U.S. rail carloadings in 2011 were 6,110,554, up 3.2% (186,751 carloads) over the first five months of 2010. Neither 2011 nor 2010 include the Memorial Day holiday.

For the last two months, traffic has been tracking 2010 (no growth from last year). Of course auto traffic was down in May.

The second graph is for intermodal traffic (using intermodal or shipping containers):

In contrast to carload traffic, U.S. rail intermodal traffic continues to be impressive. U.S. railroads originated 932,956 intermodal trailers and containers in May 2011, an average of 233,239 per week and up 7.5% (65,440 units) over May 2010 on a non-seasonally adjusted basis.

Seasonally adjusted U.S. rail intermodal traffic was up 0.8% in May 2011 over April 2011, the sixth straight monthly increase.

Intermodal’s weekly average in May 2011 of 233,239 units was the second highest May ever. The highest May ever was in 2006 at 233,516 units per week.

So intermodal traffic is essentially at record highs, but carload traffic (commodities and autos) is only about half way back to pre-recession levels.
