There is only one entrance to the station located on the southwestern corner at the intersection of 1st Street SE and C Street SE. Once passengers pass through these faregates, a pair of escalators brings passengers onto the platform. There are two elevators for handicapped passengers, one from street level to the mezzanine on the northwestern corner at the intersection of 1st Street SE and D Street SE and another between the mezzanine and platform. Capitol South station utilises an island platform layout with two tracks, D1 and D2. Eastbound trains to
New Carrollton or
Largo use track D1 whilst westbound trains to
Vienna,
Franconia–Springfield, or
