On Tuesday, we posted our sixty-sixth photo challenge to see how well you knew Metro. I took photos of five Metro stations. Here are the answers. How well did you do?

This week, we got 28 guesses. Thirteen got all five. Great work, Justin…, Mike B, Peter K, Alex B, AlexC, MZEBE, Roger Bowles, FN, Adam L, JamesDCane, Dylan P, Spork!, and Mr. Johnson!

Image 1: McLean

The first image shows McLean station. This vantage point, from the pedestrian bridge across Route 123, is looking toward Tysons Corner. The details should tell you that this is one of the new Silver Line stations. The roof type, Tysons peak, narrows the station down to two: Spring Hill and McLean. In case you couldn’t quite make out the roof type, the fact that the bridge is below the level of the platform tells you the the station will be a Tysons peak, since Silver Line stations with overhead mezzanines have the gambrel type.

The key difference between McLean and Spring Hill is that Spring Hill (and Greensboro) are in the median of Route 7, while McLean (and Tysons Corner) are to one side of Route 123. Since this station isn’t in the median, it must be McLean. For comparison, we featured Spring Hill in week 64.

Twenty-four got this one.

Image 2: Branch Avenue

The second image shows Branch Avenue station. The roof here is of the high peak variety, narrowing it down to one of just four possible stations. In addition to that, there are two main clues. First, the bridge over the yard lead in the distance at left. The second clue is the trapezoidal blocks where the columns meet the roof. None of the other high peak stations have this feature; it’s exclusive to Branch Avenue.

Twenty-one knew this one.

Image 3: Grosvenor

This picture shows the view from the platform at Grosvenor. The station here is in a shallow open cut, like its neighbor to the north, White Flint. The main clue here is the narrow pedestrian causeway leading from the bus loop to the mezzanine, above the tracks here.

Eighteen got this one correct.

Image 4: Farragut West

The fourth image shows the 18th Street entrance to Farragut West. The escalators in the foreground don’t lead (directly) into the Metro. But the Metro entrance is in the background. The setting clearly narrows this down to one of the downtown stations. The clues here include the orange square to the right, the bronze-colored escalators in the foreground, and the orientation of the Metro escalators and elevator.

Twenty-one guessed Farragut West.

Image 5: Mount Vernon Square

The final image shows the original elevator to Mount Vernon Square station. When the Walter Washington Convention Center was constructed above the station entrance, the mezzanine was reconstructed and enlarged. As a result, two new elevators were built between the mezzanine and the southwest corner of M and 7th Street NW. But the original elevator was left in service (in fact, I used it right before taking this picture). The old elevator leads up to the northwest corner of M and 7th.

The brick archway is part of an apartment building built over a parking lot that surrounds the elevator. It’s a very odd arrangement which isn’t repeated elsewhere in the system. Seventeen guessed correctly.

Next Tuesday we’ll have five more photos for you to identify. Thanks for playing!
