On Tuesday, we featured the 153rd challenge to see how well you know the Metro system. Here are the answers. How’d you do?

This week, we got 17 guesses. Seven of you got all five. Great work Robb, Peter K, Nathaniel Lovin, Isaac Alvarez, People’s Republic Soldier, AlexC, and Joe M!

As Roman Mars, host of the 99% Invisible podcast, is fond of saying: Always read the plaque. Doing so would have helped you get through this week’s wordy challenge.

The first image looks upward to the rim of the circular opening at Dupont Circle’s north entrance. In 2007 an excerpt of Walt Whitman’s poem The Wound Dresser was inscribed here to honor the AIDS crisis. Dupont Circle has long been the center of DC’s gay community. This art/memorial is a fairly recognizable element of the station, and it looks like this image was an easy guess for most of you.

Sixteen of you knew this one.

The next image shows the bottom of the memorial plaque in the mezzanine at Fort Totten to the victims of and first responders to the 2009 crash between two Red Line trains near the station. The plaque is situated so that it is not easy to see when transferring between the train lines here, but it is very visible to people entering the station or transferring from buses. We featured the uppermost portion of this plaque in week 82.

Eleven of you got this one right.

The third image shows a portion of the Journeys artwork at NoMa station. This element includes the poem Journeys I by Dolores Kendrick, near the northern entrance to the station.

Ten of you figured this one out.

The fourth image shows a plaque just outside the mezzanine at Rhode Island Avenue station. The station sits on land that was formerly home to the Columbian Harmony Cemetery. The graves were relocated to Landover in 1960 when a real estate developer purchased the land. Some of the land was later used for the Metro station.

Fourteen of you guessed correctly.

The final image was the most difficult. This plaque is located in the mezzanine at Wheaton, just to the left of the escalators leading down to the cross passage between the station’s two train tunnels. While it’s true that Wheaton didn’t open until 1990, construction was well underway by 1987, and the National Capital Section of the American Society of Civil Engineers awared their Outstanding Civil Engineering Achievement to the station.

The award was given for the Wheaton Station and Tunnels project, which included not just the station itself, but also the line on either side. This project was the first use of the New Austrian Tunnelling Method in the United States.

Wheaton is not the deepest station in the system. That honor goes to Forest Glen, which opened on the same day as Wheaton. But Wheaton has the longest single-span escalators in the western hemisphere; a significant achievement on its own.

Nine of you came to the correct conclusion.

Great work, everyone. Thanks for playing! We’ll be back in two weeks with challenge #154.
