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

This week, we got 44 guesses. 24 of you got all five. Great work, everyone!

Image 1: Georgia Avenue

The first image shows an entrance to Georgia Avenue station, viewed from the Park Place across the street. The primary clue here is the lozenge-shaped entrance pavilion. This style of entrance is only present at three stations, with Columbia Heights and Congress Heights rounding out the set.

Other clues included the acute intersection of Georgia and New Hampshire Avenues and the rowhouses of Pleasant Plains in the background. 37 got it right.

Image 2: Ballston

The second image shows the entrance at Ballston station. This canopy is fairly unique, though a similar style is used for the eastern entrance at Judiciary Square. The commuter store in the center provides another hint.

39 knew this one.

Image 3: Judiciary Square

The third photo was taken at Judiciary Square. While there’s not a lot of direct evidence in the photo, the reflection in the water is of a very distinctive building: the National Building Museum. The iconic structure stands directly across from the eastern entrance to Judiciary Square, which has an uncovered escalator shaft.

40 guessed Judiciary Square.

Image 4: Rhode Island Avenue

Rhode Island Avenue station featured in our fourth picture. The station is visible at left, viewed here from the new pedestrian bridge linking the station to the Metropolitan Branch Trail. The fencing on either side of the bridge is fairly distinctive, and that was the main clue.

The radio tower and the distant Capitol dome may have helped you narrow down the possibilities. 40 sussed out the right answer.

Image 5: Tenleytown

The last picture comes from Tenleytown. We featured a very similar photo in week 57, as it happens.

Tenleytown is the only Arch I or Arch II station where the elevator bypasses the mezzanine and goes straight to the platform. Because of this, there’s a solitary faregate, TVM and exitfare machine at the south end of the platform.

29 came to the correct conclusion.

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