On Tuesday, we posted our seventieth 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 39 guesses. Twelve got all five. Great work, Roger Bowles, Peter K, Russell H, JamesDCane, AlexC, Jack M, Solomon, Mike B, Chris H, MZEBE, Mr Johnson, and FN!

Image 1: U Street

The first image shows the Vermont Avenue entrance to U Street. The primary clue here is the statue visible in the distance. That’s the African American Civil War Memorial, which lent its name to the station. The statue stands in the plaza at the corner of Vermont and U, where the eastern entrance to the station is located.

Twenty-nine guessed correctly.

Image 2: Rosslyn

The second photo shows the escalator shaft at Rosslyn. This shaft contains the fifth-longest bank of escalators in the system. The moving steps here span 194 feet, behind only Wheaton, Bethesda, Woodley Park, and Medical Center.

The primary identifying feature here is the elevator shaft at center. At Rosslyn, there are four escalators, with an elevator shaft sitting in the middle. This is the only station with this arrangement. No other station has four long escalators and no other station has an elevator piercing the escalator shaft. This elevator has been decommissioned, replaced by a bank of three elevators at the station’s new east entrance.

Thirty-five knew this was Rosslyn.

Image 3: Stadium/Armory

The third picture shows the northern entrance to Stadium/Armory, looking down toward the trainroom and platform. This view is unique in the system. At virtually every underground station, you enter the trainroom above the tracks at mezzanine level. There, you go through fare control and then descend to the platform.

But at three stations— Union Station, Farragut North, and Stadium/Armory— one of the mezzanines is located outside the trainroom, and you actually enter the train room through the end wall at platform level. In this case, you can see the tall “doorway” around the escalators, which wouldn’t be necessary if the mezzanine floated above the platform.

At Union Station (north), there are two escalators split by an elevator. At Farragut North (north), there are three side-by-side escalators, but the ceiling isn’t vaulted at this end to make way for a (formerly) planned underground ramp to I-66.

The only station that fits is Stadium/Armory. You also could have confirmed that by noting the signage at the foreground. “New Carrollton” and “Largo Town Center” are readable on the sign to the left, indicating that this is a Blue/Orange/Silver station. Thirty scored a goal on this one.

Image 4: West Hyattsville

The fourth image was taken at West Hyattsville. This station has side platforms, which is what allows this vantage point. The sloped roof here holds the skylights that are above the escalators to the Greenbelt platform. The parking lot is in the background. This is a station with unique architecture, and this sloped roof is only present at West Hyattsville. Huntington (south) has a similar escalator covering, but it isn’t visible from anywhere other than below (as we did in week 12).

Additionally, the vertical bars close to the camera are parts of a fence that WMATA installed along the platform wall a year or so ago and this fence is unique to West Hyattsville. Seventeen figured it out.

Image 5: Cleveland Park

The final image was the hardest. It shows the staircase at Cleveland Park. You can tell from the design of the vault that this is an Arch I station, which is a type only present on the Red Line between Woodley Park and Medical Center.

However, of those stations, the only place where an escalator and staircase are next to each other is Cleveland Park. At the other stations with this design, the end of the mezzanine is capped with a pair of escalators. Only at Cleveland Park is the solitary escalator accompanied by a stair. Twenty-one guessed correctly.

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