Camp David, known formally as the Naval Support Facility Thurmont, is the President’s country residence. Located in Catoctin Mountain Park in Frederick County, Maryland, Camp David has offered Presidents an opportunity for solitude and tranquility, as well as an ideal place to host foreign leaders.
Adapted from the federal employee retreat Hi-Catoctin, President Franklin Roosevelt established the residence as USS Shangri La, modeling the new main lodge after the Roosevelt winter vacation home in Warm Springs, Georgia. President Eisenhower subsequently renamed the institution in honor of his grandson David.
Camp David has been used extensively to host foreign dignitaries. Prime Minister Winston Churchill of Great Britain attended the first such meeting in May of 1943; the summit held at the residence in 1978 for Egyptian President Anwar al-Sadat and Israeli Prime Minister Menachem Begin resulted in what are now known as the Camp David Accords.

Investigators are working the scene to determine a cause. One train apparently rammed a stationary train on the system's Red Line. One of the dead was identified as the operator of the moving train.
The Washington Post cited signal system failure and operator error as possible causes of the accident.
The force of the impact crushed the rear car of the sitting train "like an accordion," witnesses said, and forced the moving train into the air. It landed atop the other train.
Rescue crews searched the wreckage and surrounding area for victims. The Post said five bodies were removed from the crash debris Tuesday morning.
Commuters Tuesday were warned to avoid using the Red Line if possible. The Red Line is the busiest section of Washington's Metro system.
