DALLAS (AP) The snowplows were ready, the sand trucks deployed. Officials felt this ice storm unlike the one that paralyzed the region during the 2011 Super Bowl week would be handled better.

But the ice came down thicker than expected, the snowplows did little good and before the proper equipment could be relocated, the Dallas-Fort Worth area was again locked in ice.

Texas Department of Transportation spokesman Tony Hartzel says snowplows won't clear ice, so other equipment had to be brought in.

Dallas Area Rapid Transit spokesman Morgan Lyons says that public transit agency is considering changes in how it responds to winter emergencies, including experimenting with scrapers on light-rail cars to clear ice from overhead power line
