Total operating revenue for the current quarter was $1.26 billion, compared with $1.15 billion for the second quarter 2011. Load growth of 13% in Intermodal (JBI) and 16% in Integrated Capacity Solutions helped drive a 13% and 23% increase in segment revenue, respectively. Dedicated Contract Services segment revenue increased by 1%, but the company's Truck (JBT) segment revenue decreased by 3%.

Operating income for the current quarter totaled $137 million versus $113 million for previous year's quarter. Operating income increases from steady demand and higher volumes in JBI and ICS and lower fuel costs in DCS and JBT were partially offset by increases in rail and truck purchase transportation costs, driver wages, toll road charges, maintenance costs and safety costs compared to the same period a year ago.
