Federal Triangle is located on the Orange Line (Orange Line), one of Washington DC's operational metro corridors. It sits between Metro Center and Smithsonian, making it a convenient stop for the surrounding area.

What makes Federal Triangle particularly useful is its interchange connection with Silver Line, Blue Line. If you need to switch between lines, this is where you'll do it – and you won't need to exit or purchase a new ticket. The interchange corridor is clearly signposted with color-coded directions.
