The nation's transit systems may remain on high alert for only a few days.

Counter-terrorism officials say the orange alert is in place as a precaution against copycat attacks following the London bombings. Three federal officials say barring any new intelligence from the London investigations or elsewhere, the Homeland Security
Department could lower the threat level from orange back to yellow as early as next week. The latest threat level increase covers rail, subway and bus systems.
