The trend in North American freight volumes continues to follow the path of general malaise that the economy is experiencing, according to Rosalyn Wilson, senior business analyst at Delcan Corporation. The number of freight shipments in June was up a scant 1.3 percent from the previous month, while at the same time total freight costs declined 0.1 percent. The economy has been flat for several months and is even beginning to trend downward in terms of new orders and manufacturing output. This slowdown on manufactured goods is putting downward pressure on freight.
