Contributor Jason Levinn posed this question:

Has anyone else wondered why WMATA/MWAA/DTP chose not to put in a Wolf Trap stop on the Silver Line? There’s such a large gap between Spring Hill and Reston, one would think it might make sense for several reasons.

Indeed, the distance between the Spring Hill and Wiehle-Reston East stations is about 6 miles. That would make it the longest gap between stations once Phase 1 of the Silver Line opens. And being able to get off the Metro and take a short walk to see an event at Wolf Trap would be much more convenient compared to what exists today. But some of our other contributors had some great explanations as to why there is no station currently planned there:

Michael Perkins: It would be a total waste of money. An inline stop would cost somewhere between $100-200 million, maybe more, and there is essentially no development potential around the site. There’s a national park and single-family homes.

No one is going to agree to rezone that area to allow anything like transit-oriented development, and the road access isn’t appropriate for a commuter lot. Wolf Trap has several dozen events a year, but it’s not enough by itself to drive much transit use.

Matt Johnson: Originally, the Silver Line plans included a provision for a future station at Wolf Trap, but in the deal struck (by Ray LaHood) to make it cost effective, the planned provision was deleted.

Tony Goodman: The agreement between Fairfax County and MWAA includes a “Concurrent Non-Project Activity” (or CPNA) to allow for a future possible station.  These CNPAs are items that MWAA is providing that are outside the scope of the FTA project agreement.

Although currently there are no plans to build a Wolf Trap station, the current project includes accommodations necessary to allow the addition of a future passenger station, including a vertical tangency (flat spot).
