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

We got 35 guesses this week. Nine of you got all five correct. Great work Patrick, Andy L, MZEBE, Justin…., Aaron R, Chris H, Sandy K, FN, and Mr. Johnson!

Image 1: Morgan Boulevard

The first image shows an eastbound Blue Line train arriving at Morgan Boulevard. Above the tracks, you can see the mezzanine, which clearly exhibits the “Gull II” architecture that the three stations opened in 2004 have. But unlike NoMa and Largo, Morgan Boulevard’s mezzanine is above the tracks. Twenty-eight of you got this one right.

Image 2: Brookland

The next picture shows the canopy at Brookland. The primary clue here is the curved roof. Only two stations have curved platforms (and therefore curved canopies): Brookland and Silver Spring. The curvature is greater at Brookland than at Silver Spring, and also you can’t see any tall buildings here. Another clue is the Michigan Avenue overpass in the distance, and the perspective of the photo, which was taken from Monroe Street. Twenty-nine of you figured out this was Brookland.

Image 3: East Falls Church

The third image shows the platform at East Falls Church. This is a “general peak” station, as you can see from the line of skylights. But the real clue here is the full-height walls on either side. Only Dunn Loring and East Falls Church have full-height walls like this. You can tell that this isn’t Dunn Loring because of the “hole” in the platform floor (by the group of waiting riders) where you can see down into the mezzanine. At Dunn Loring, the mezzanine is above the tracks. Twenty-six guessed correctly on this one.

Image 4: Waterfront

The fourth image shows Waterfront station. This one can only be Waterfront because of two attributes you can see here. First, from the pylon, you can see that this station is only on the Green Line (not the Yellow, too). From there, only two “waffle” stations have Green-only service. The neighboring station, Navy Yard, has mezzanines on either end, which you can tell this station doesn’t. Twenty-seven hit the mark.

Image 5: Medical Center

The final image was the hardest. Even for me. Like the rest of you, I get to guess on the photos when Peter submits them (I give him my guesses and (so far) he tells me I’m right). But you can use the process of elimination to narrow this one down to Medical Center.

First off, this is clearly a mezzanine-to-street bank of escalators (because of the visible canopy at the top). It’s also a very long bank, so this has to be a deep station without an intermediate distribution level (like at Cleveland Park and Van Ness). Only a few stations fit those criteria.

The only stations that do that and also have the escalator canopy are Dupont Circle (south) and Medical Center. Stations like Wheaton and Bethesda have escalators that land in a covered mezzanine, and Woodley Park’s has a landing just below street level (to allow for a future entrance across Connecticut Avenue). And this can’t be the south Dupont entrance because those escalators are silver, are close together, and have higher sides. Only 15 of you got this one right.

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

Thanks again to Peter K for submitting photos. If you think you have what it takes, email your photos to whichwmata@ggwash.org.
