Amtrak service was suspended for more than two hours Saturday afternoon at Union Station in Washington after railroad officials received a bomb threat. Amtrak and District of Columbia officials evacuated about 1,000 people from the station, a popular tourist site, while they conducted a search. No bombs were found, and service resumed by late afternoon.
