Very little of the actual station area remains accessible due to cave-ins, but the adjacent utility areas are still more or less intact.
To the northeast is a maintenance area with a protectron bay close to the Dupont station exit. In the passage outside this area will be a pair of super mutants. Continuing through this passageway is a ruined metro tunnel running in two directions, with the exit to Dupont Circle to the east.
Beyond the train tunnel to the west is a small raider encampment with a lone raider, and a utility tunnel with another raider. The tunnel leads south into an office with a security terminal which controls two automated turrets in a natural cavern that is accessible via stairs circling down to from the office. Two more raider are patrolling the large area below the turrets. The cavern leads south to a large utility door that separates the caverns from what appears to be an old sewer tunnel. The sewer tunnel is defended by mines and traps to prevent feral ghouls from advancing past the utility door and into the cavern. Several feral ghouls lie dead there along with a lone raider who died near an access door into the cavern. At the end of the sewer tunnel to the southeast is a door to Metro Central.
The name of this station appeared on an advertisement for the Metro.
Near the Dupont station exit is an office with a protectron bay with a Metro protectron. If hidden from both the Metro protectron and the two super mutants in the hall, a humorous exchange can be heard as the protectron accosts the super mutants for tickets. If the most direct route is taken on the Galaxy News Radio quest, the office will be reached before the hall; an ideal location to hear the exchange while hiding behind the file cabinets.

There is a cut poster in the game files that points out that the Dupont Station had just been remodeled before the war.
