On Tuesday, we featured the 150th challenge to see how well you know the Metro system. Here are the answers. How’d you do?

This week, we got 16 guesses. Nine of you got all five. Great work psualex, ArlFfx, Peter K, AlexC, Isaac Alvarez, Christopher Deal, J-Train-21, Jay H, and Greg Jordan-Detamore!

Image 1: Clarendon

The first image shows a compass rose surrounding the station entrance pylon at Clarendon. For those of you who took a deep look at the picture, it was easier than intended, because the word “Clarendon” is written into the concrete on the escalator side of the rose. I didn’t notice that, but both Peter K and Greg Jordan-Detamore picked up on it. If you didn’t, the other way to solve this is the staircase flanked by escalators leading to the Metro. Most stations have two or three escalators. Rarely is this escalator-stair-escalator arrangement used.

Twelve of you knew this one.

Image 2: Takoma

The second image shows a view of the escalator entrance to Takoma station. This is one of only a few stations where three escalators take up the entire width of the platform at one end of the station. Takoma is the only above-ground station with this configuration. As a result, the space between the escalators and the “Gull I” canopy is cavernous, and this is a distincitve and unique design in the system.

Ten of you got this one right.

Image 3: Tysons Corner

The third image shows the view from the mezzanine at Tysons Corner station, looking northward toward the Tysons Galleria. The architectural features here are very clearly Silver Line designs. All but one of you guessed that this was one of the stations in Tysons. But it can only be Tysons Corner, because the metal frame at top is the bottom of the “Gambrel” style canopy. And while there are three stations with Gambrel canopies (at least until the Dulles/Ashburn extension opens), only Tysons has a road passing under the platform.

Thirteen of you figured this one out.

Image 4: East Falls Church

The fourth image shows a Vienna train standing on the platform at East Falls Church. The high walls and canopy supported from the walls, rather than columns means this has to be one of the I-66 median stations (and the train’s destination discounts all non-Orange stations). However, it can’t be West Falls Church, Dunn Loring, or Vienna because those stations all have mezzanines above the platform, and therefore don’t need light shafts down to the mezzanine below, as East Falls Church has.

Fifteen of you guessed correctly.

Image 5: Metro Center

The final image shows the hint of the Macy’s star in the 13th & G mezzanine at Metro Center. While several of you noted that this was the Macy’s entrance, it’s actually one of two at Metro Center. Both the 13th & G and 12th and G mezzanines have direct connections to Macy’s, on opposite sides of the store. This is the only connection from Metro directly into a Macy’s, though Metro does have a direct connection to Pentagon City Mall, which has a Macy’s.

Twelve of you came to the correct conclusion.

Great work, everyone. Thanks for playing! We’ll be back next week with challenge #151.
