WASHINGTON, July 27 (Reuters) - Washington's main railway terminal, Union Station, was being evacuated on Wednesday because of a bomb threat, a police officer told Reuters.

"We got a bomb threat," the officer, who did not give his name, said as he urged people to leave Union Station in downtown Washington near the U.S. Capitol Building.
