Downtown Largo is located on the Silver Line (Silver Line), one of Washington DC's operational metro corridors. This is the final stop on the line, so all passengers alight here. Trains turn around and head back towards Ashburn.

What makes Downtown Largo particularly useful is its interchange connection with 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.
