On Tuesday, we featured the thirty-third issue of our “whichWMATA” series. This week, all five photos were guest submissions from reader thisisjamesj.

This week we got 44 guesses. Three people got all five correct. Great work, Mr. Johnson, Skierbum, and Peter K!

Image 1: Dupont Circle

The first image shows the escalators at the Q Street entrance to Dupont Circle. This entrance is very distinctive because of the large bowl surrounding the escalator shaft. Several of you recognized the PNC Bank building in the background as well. All but one person knew this one. Great work.

Image 2: Gallery Place

The second picture shows the interlaced escalators at Gallery Place. This is the only place in the entire system where you can get a view like this, though Tysons Corner station also has interlaced escalators. The reason that Gallery Place has this arrangement is because the mezzanine is directly above the point where the lines cross. At Metro Center and L’Enfant Plaza, the mezzanines above the upper level are at either end, and the lower level isn’t beneath them. Forty of you got this one right.

Image 3: L’Enfant Plaza

This one was a little trickier. There were two primary clues to help you identify L’Enfant Plaza. The first is the construction. The hanging lights are in place because WMATA is renovating the underside of the mezzanine above, and it’s been this way for quite a while. The other clue is the shape of the vault wall. It’s almost vertical here, which is only the case at L’Enfant. At the other vaulted stations, the wall is sloped (being farther away from the top of the train than the bottom of the train). A little less than half — 20 — of you guessed correctly.

Image 4: Van Ness

This week, image 4 was the hardest. This picture depicts the pedestrian connection under Connecticut Avenue at Van Ness. While tunnels with similar design elements are common throughout Metro, this one is unique in its arrangement. The escalators from the mezzanine arrive at this level directly under Connecticut Avenue, ending at a T-junction. The corridor seen here allows people to exit to either the east or west side of Connecticut. It can’t be Cleveland Park because at Cleveland Park, the escalator shaft to the mezzanine and the escalator shaft to the east side of Connecticut face the same direction. Only 9 people got this one.

Image 5: Metro Center

The final image shows the lower level platform at Metro Center. The clues here are the shape of the vault (which is different from other vaults in the system) and the slight change in height of the ceiling (the dark line running parallel to the tracks). The other clue that should’ve helped you narrow it down is the mezzanine being flush with the wall at the end of the trainroom and also being almost full-width there.

At most stations, the mezzanine floats above the platform, but where it meets the wall at the end of the station, it narrows, like the top of an inflated balloon. At many of the stations that people guessed on this one, the mezzanine is also in the center of the station, not one end. Several people also guessed Farragut North, which surprised me since the Blue Line doesn’t call there. Still, 21 of you figured this one out.

As always, great work! Thanks for playing.

I’d again like to give a special thanks to thisisjamesj for submitting his great photos this week!

We’re always looking for reader submissions, so while you’re riding Metro keep your eyes (and cameraphones) peeled for unique stations and architectural features. You can submit your photos to whichwmata@ggwash.org.
