US Transportation Secretary Anthony Foxx told reporters Tuesday he seriously considered ordering a shutdown of Washington's troubled subway last week and warned the subway agency he would not hestitate to use that authority if necessary.

On Saturday, federal officials ordered Metro to tighten safety standards because of a rail fire. The response by Metro subway employees to the explosion of a third-rail insulator and fire on Thursday showed major lapses by the system's control center, the Federal Transit Administration (FTA) said in a directive.
