On Tuesday, we featured the fifty-second issue of our “whichWMATA” series. This week, all five photos were guest submissions from reader Peter K.

We got 27 guesses this week. Ten of you got all five. Great work, Sand Box John, Andy L, Eric, Aman, Mike Plumb, MZEBE, Justin…., JamesDCane, FN, and Mr. Johnson!

Image 1: Cheverly

The first image shows the underside of the entrance to Cheverly station. At Cheverly, the Orange Line is sandwiched between the CSX freight line and the Amtrak Northeast Corridor. To enter the station, passengers first have to ascend to a bridge over the CSX tracks, which is home to the fare array. The bridge is somewhat distinctive, and we featured the station entrance in week 38. Seventeen of you figured it out.

Image 2: Pentagon

The second image was clearly the easiest, as all 27 of you got it right. It shows a train on the lower level of Pentagon station. This station has a split-level arrangement, which you can tell because of the wall on the right and the sign that indicates trains in the other direction are on a different level. And since there’s signage for the Yellow Line, it can’t be Rosslyn, so it’s obviously Pentagon.

Image 3: Greenbelt

The third image shows the mezzanine skylights at Greenbelt station. They’re located between the tracks and the offramp from the Beltway and provide natural light into the interior part of the station. We actually used this same feature, though from a very different angle, in week 1. Twenty-one of you guessed correctly.

Image 4: Vienna

The fourth image shows the south bus loop at Vienna. You should have been able to narrow this down to one of about ten stations because of the Fairfax Connector bus that’s visible. This must be Vienna because of the new awning visible at bottom and the townhouses under construction in the distance. The awning is similar to one at West Falls Church, but that bus loop is not adjacent to a parking garage and is in a freeway median. We featured it in week 29. Twenty-two of you got this one right.

Image 5: Dupont Circle

The final image shows one of the elevators in the north (Q Street) mezzanine at Dupont Circle. Even if you’ve never seen this sign, you could figure this one out from the process of elimination. The sign indicates that this is a station on the Red Line and you can see a waffle vault. That narrows this to the six stations between Union Station and Dupont Circle.

The sign also says the elevator goes only to the Glenmont platform. That means this can’t be an island platform station, which eliminates Union Station and Farragut North. And the arrangement of Gallery Place and Metro Center means that the elevators to the Red Line platforms aren’t set into the vault in the mezzanine like this. That leaves Judiciary Square and Dupont Circle.

This can’t be Judiciary Square because the elevators there don’t stop in the mezzanine. They go straight from the street to the platform and each has a faregate on the platform. So this must be Dupont Circle. Sixteen of you did the math and got the right answer.

Thanks to everyone for playing! Great work. Stay tuned. We’ll have five more images for you next Tuesday.
