For the first nine months of 2011freight shipments as measured by the Freight TSI are up 2.5 percent.
Freight shipments in September are up 16.2 percent from the recent low in April 2009 at 94.3, which were at the lowest level since June 1997 at 92.3. September is down 3.3 percent from the historic freight shipment peak in January 2005 at 113.3.
