CHICAGO | When derailed freight train cars carrying ethanol burst into flames just 50 miles from her Chicago suburb, killing a motorist who tried to flee, Barrington Mayor Karen Darch saw her worst fears realized.

"This is exactly the kind of thing we've been afraid of," said Miss Darch, who tried but failed to stop a railroad sale that will boost freight traffic through her village. "Any community could find themselves in that situation."

The derailment earlier this month highlights the struggle to prevent such disasters along the 140,000-mile U.S. rail network. The pressure is on to tackle outstanding safety issues, with hazardous cargo shipments expected to soar in coming years. Fears that terrorists might view chemical-laden tankers as easy targets adds to the urgency.

Competing interests that sometimes pit the government against railroads, suburbs against cities or chemical makers against environmentalists complicate efforts to secure the transport of about 1.7 million carloads of hazardous material a year.

One of the most contentious issues has been new federal regulations requiring that companies reroute trains hauling the most toxic materials away from big cities. Those rules apply to substances that can vaporize, like chlorine.

A 2005 train crash in Graniteville, S.C., that killed nine people and injured hundreds of others involved chlorine, used by cities to purify water. The wreck ruptured a car carrying the chemical, releasing a poisonous cloud over the town.

Tankers amount to "hell on wheels rolling through our communities," Rep. Edward J. Markey, Massachusetts Democrat, has said in support of the rerouting rules. In a catastrophic event, he said, tankers can contain enough chlorine to kill 100,000 people in 30 minutes.

Other new federal rules that have been partially implemented require that new tankers be better fortified to lessen the chances of spills or explosions. Amid current economic woes, though, railways aren't buying many new tankers.

Rail companies note accidents already are at historic lows.

Out of the more than 1 million train cars that carried hazardous cargo in 2008, there were 21 train accidents where some material was released; that's down from 118 in 1980, according to federal data.
