Washington Union Station is one of the most iconic and heavily trafficked train stations in the United States. Located at the intersection of major regional and national rail lines, Union Station serves as a central hub for:

The Northeast Corridor (NEC)—Amtrak’s busiest route, connecting Boston, New York, Philadelphia, and D.C.

Long-distance trains bound for Chicago, Atlanta, New Orleans, and Miami.

Regional services to Virginia, North Carolina, and Pennsylvania.

Supporting all this activity is the amtrak office washington dc, where travelers, government officials, Amtrak employees, and long-haul passengers converge to plan and coordinate journeys.
