FILE - This March 13, 2014 file photo shows Transportation Secretary Anthony Foxx on Capitol Hill in Washington. The Transportation Department issued an emergency order on May 7 requiring that railroads inform state emergency management officials before moving large shipments of crude oil through their states, and urged railroads not to use older model tanks cars that are easily ruptured in accidents, even at slow speeds. "All options are on the table when it comes to improving the safe transportation of crude oil, and today’s actions, the latest in a series that make up an expansive strategy, will ensure that communities are more informed and that companies are using the strongest possible tank cars," Foxx said in a statement.
