From Bloomberg: Waste on Freight Cars Gains Most Since ’94 Confirming Rebound (ht Brian)

From the Association of American Railroads: Rail Time Indicators: Waste and Scrap Materials traffic in May 2010 was "up 37.1% from May 2009 and down 20.4% from May 2008."

Waste traffic was down from the April level. The Bloomberg article suggests this confirms the "economy is strengthening" - I'd say this shows the recovery has been sluggish (still well below the May 2008 level) and the economy might have slowed in May (although one month doesn't make a trend).
