Union Pacific said Thursday, Oct. 18, 2012, that its third-quarter profit climbed 15 percent because price increases and more automotive and chemical shipments helped the railroad offset a 12 percent drop in coal shipments. The railroad reported $1 billion in net income, or $2.19 per share. That's up from $904 million, or $1.85 per share, a year ago. (AP Photo/Nati Harnik)
