US prepares safety rules for subways
2009 crash in DC was impetus for regulations
Federal officials have begun drafting safety standards for the nation’s subway and light-rail systems, three years after a deadly crash on a line operated by the Washington Area Metropolitan Transit Authority exposed vast gaps in oversight of trains that transport millions of people a day. The Transportation Department has long regulated safety for airlines and Amtrak, but it did not set safety standards for subway and light-rail systems. The result was a patchwork of rules and regulations.
