Union Pacific Corp, the largest publicly traded U.S. railroad, reported a 17 percent rise in quarterly profit, partly due to a rise in shipments at its agricultural products business. Revenue at the business increased 19 percent in the second quarter ended June 30. Net income rose to $1.29 billion, or $1.43 per share, in the quarter from $1.11 billion, or $1.18 per share, a year earlier. Total revenue rose 10 percent to $6.02 billion. (Reuters)
