|U.S. transportation officials on Wednesday offered $10 million in grants for states to upgrade highway-rail crossings and tracks in response to a recent surge in flammable fuel shipments. The announcement from the U.S. Department of Transportation comes as rail crossing collisions have increased over the past several years, following more than three decades of steady declines. The grants would pay for improvements along rail routes that transport flammable fuels. There were more than 2,200 rail crossing collisions in 2014, killing 269 people and injuring 849.
