On Tuesday, we featured the ninety-second challenge to see how well you knew the Metro system. Here are the answers. How’d you do?

This week, we got 26 guesses. Sixteen got all five. Great work, Transport., Peter K, Robb, Justin…, Solomon, Steven Yates, Kevin M, Andy L, AlexC, Travis Maiers, MZEBE, Stephen C, J-Train-21, dpod, JamesDCane, and We Will Crush Peter K!

Image 1: Waterfront

The first image shows the entrance to Waterfront station. This station is in the center of the area cleared for urban renewal in the late 1950s. In the 1950s and 1960s, modernist buildings replaced rowhouses in Southwest. The building in the distance, 300 M Street SW, is typical of the style of buildings that make up Southwest Waterfront. In the foreground, the newly rebuilt plaza is another clue.

20 guessed correctly.

Image 2: Pentagon

The next picture looks down toward the Huntington/Franconia track at Pentagon. This is one of two split-level stations. Like at Rosslyn, here the inbound track is one level above the outbound track. This is necessary because the Blue and Yellow Lines diverge immediately north of the station, and the tracks need to cross on different levels.

While the southern end of Rosslyn station is very similar to Pentagon, there are two key differences. In this case, three things are missing that mean this can’t be Rosslyn. First, at the outbound end of Rosslyn, there’s a destination indicator sign that flashes either Vienna/Wiehle or Franconia depending on how the switch is set. At Pentagon, that sign is on the inbound end (upper level) and opposite the entrance (featured in week 41).

Additionally, Rosslyn includes a “welcome to Virginia” sign at the outbound end, the only state welcome sign in the system. Finally, from this angle at Rosslyn, you’d be able to see the interlocking signal just inside the tunnel on the right side. The light you see on the left wall is an emergency telephone blue light.

19 got it right.

Image 3: McPherson Square

The third photo features a sign at McPherson Square directing riders to the Vermont Avenue/White House exit. McPherson Square is the closest station to the White House, and signage inside the station directs riders to the correct exit.

23 knew the correct response.

Image 4: Largo

The fourth image shows a distant view of Largo station. The parking structure is somewhat distinctive, though similar to the one at College Park, which was built around the same time. However, the primary clue is the artwork outside the station, Largo Beacon. The sculpture is just to the left of the parking garage from this perspective, and we featured it in week 4.

23 guessed Largo.

Image 5: Shady Grove

The final image was taken in a stairwell at the southern garage at Shady Grove. This one was a bit trickier. Few stations have multiple garages, which should have helped you narrow this down. At Shady Grove, the older southern garage sits south of the eastern bus loop, and from this perspective, we can see the newer north garage. Additionally, just right of center, there’s an idling Ride On bus, which may have helped you narrow this down to Montgomery County.

18 figured it out.

Thanks for playing. Great work! We’ll be back in two weeks with another quiz.
