On Monday, we posted our fifteenth photo challenge to see how well you know Metro. I took photos of five Metro stations. Here are the answers. How well did you do?

We got 44 guesses on this post. A whopping 26 of you (over half) got all 5 correct. Great job!

Image 1: Rosslyn.

The first image shows the escalator shaft at Rosslyn station. This shaft is distinctive because the four escalators are split by an elevator, which ascends through them. When Metro opened the new elevator-only entrance, however, it this elevator was deactivated. A development atop the station site will soon demolish the top of the elevator, but it’s not clear if WMATA will remove the remainder of the shaft. 37 people knew this one.

Image 2: Huntington.

These “County of Fairfax” seals are at Huntington station, next to the tunnel portals at the southern end of the station. There’s one on either side of the tracks. The seals line up with the circular holes in the buttresses, which we featured in week 8. One clue there is the “end ATC” sign, which indicates that this is the end of the line. 36 got this one right.

Image 3: Columbia Heights.

The third image was taken at the eastern entrance to Columbia Heights station. The canopy that’s visible here is unique to two stations: Columbia Heights and Petworth. The Kenyon Square building visible through the glass is the clue to narrow it down to Columbia Heights. 35 correctly guessed this one.

Image 4: Union Station.

The fourth image shows the cramped northern mezzanine at Union Station, looking down from the elevator landing on the commuter rail level. This mezzanine is unique because of its size and shape, necessary to fit it in under Union Station. The four flags show that this is a key station. 38 knew this one.

Image 5: White Flint

The final image is a picture of White Flint from 2009. This picture is looking south at the station from above the subway tunnel. The main clue here is the Nuclear Regulatory Commission building just south of the station. 38 correctly guessed White Flint.

Congratulations to the winners!

Next Monday, we’ll have 5 more photos for you to identify. Thanks for playing!
