Here are the answers to whichWMATA week 58

On Tuesday, we posted our fifty-eighth photo challenge to see how well you know Metro. I took five photos in the Metro system. Here are the answers. How well did you do?

This week, we got just eight guesses. Two people got all five correct. Great work, Peter K and Mr. Johnson!

The first image shows the cross-vault above the mezzanine at Morgan Boulevard station. The design is very evocative of the cross-vaults at the downtown transfer stations, which we featured in week 5.

Morgan Boulevard has a Gull II roof, but is distinct from the other stations with that type, Largo and NoMa, because at Morgan Boulevard, the mezzanine is above the tracks, rather than underneath. The crossing of the vaults is created where the “trainroom” vault over the tracks intersects the vault above the entrances.

Five got this one right.

The second image shows the abrupt end of the vault at Farragut North. Like the other early underground stations, Farragut North features a waffle-style vault. But the vault ends before the northern end of the platform, replaced by a lower flat ceiling. The reason for this was to accommodate a planned ramp to the North Leg Freeway (I-66), which would have been in a tunnel under K Street. Neither the freeway nor the ramp were built, however.

Union Station also has a flat portion of the roof to accommodate a loading dock above. But it isn’t so close to the mezzanine, so this perspective isn’t possible there. Four knew this one.

The third image shows signage at Wheaton station directing customers to the station’s elevator. Wheaton is deep underground, and each track is in a separate tube here. The two platforms are connected by a cross passage at the base of the escalator shaft.

The station has just one elevator. It’s located at the north end of the southbound (Shady Grove) platform. So customers coming from the Glenmont platform have to navigate via the Shady Grove platform to find it. This signage directs them to the right end of the platform.

Even if you hadn’t seen this unique signage, the context should have helped. The reference to the “right platform” hinted that there were two platforms. And the vault wall visible in the distance indicated that the platforms weren’t right-side platforms (like at Dupont Circle). The only places where there are left-side side platforms is at Forest Glen, Pentagon, Rosslyn, and Wheaton. And the vault here only matches Forest Glen and Wheaton. Though Forest Glen has 6 elevators, not just one.

Four guessed correctly.

This image shows art mounted on a retaining wall opposite the entrance to Crystal City. The wall itself supports an elevated portion of Jefferson Davis Highway (US 1). If you hadn’t seen this art before, the only other clue was the wall, which is made of the kind of supports used frequently in highway construction.

Two figured this one out.

The final image shows the street elevator at Georgia Avenue/Petworth. If you didn’t recognize the new Park Place building, the other clue is the skewed elevator.

The angle of the elevator is due to the geometry of the surrounding streets. At Georgia Avenue, the entrance is at the southern end of the station, and from the mezzanine a passage runs perpendicular to the tracks, leading to escalators on either side of Georgia Avenue.

But the trainroom is underneath (and parallel to) New Hampshire Avenue, which crosses Georgia Avenue here at an odd angle. Since the elevator lines up with the underground passage, it is skewed in comparison with the buildings, which line up with Georgia Avenue.

Five were able to solve this clue.

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