High Quality Content by WIKIPEDIA articles! Wolf Trap is a proposed Washington Metro (WMATA) Silver Line station to be located at Wolf Trap National Park for the Performing Arts. It was originally part of WMATA`s Dulles Corridor Metrorail Project, but was eliminated to reduce the cost of the multi-billion-dollar Metrorail extension. However, the plan still exists for a future "in-fill" station, requiring funding separate from the two-phase expansion now under construction.
