Here are the answers to whichWMATA week 113. How’d you do?

On Tuesday, we featured the 113th challenge to see how well you knew the Metro system. Here are the answers. How'd you do?

This week, we got 18 guesses. Nine got all five correct. Great work, Christopher Deal, JamesDCane, Solomon, Peter K, Justin…, ArlFfx, David Duck, Peter K is a nice guy don't be hatin' on him, and J-Train-21!

The first image shows a train arriving at Union Station. I lived near here on Capitol Hill for a few months in 2017.

There are a couple of clues in the image. You can see from the train that this is a station on the Red Line. Despite the iconic nature of WMATA's “Waffle” vaults, the oldest line only has six stations with that style, and four have side platforms.

The remaining two, Farragut North and Union Station, each have sections where the vault ends with a flat ceiling. At Farragut North, it's to accommodate a planned underground ramp to the never-built Inner Loop freeway. At Union Station, it's to accommodate a loading dock.

However, at Union Station there is “no clearance” striping along the base of the vault. Farragut North does not have this feature. This picture was taken before the Union Station vault was painted white. The striping was replaced following the whitewashing.

Sixteen of you got this one right.

The second image shows a view from the parking garage at Prince George's Plaza. I lived near this station for a year when I first moved to the region more than a decade ago.

At this station, the tracks and platforms are in a deep open cut, with the parking garage sitting atop the complex. Just visible at the bottom right corner of the photo, a chain-link fence along the top of the tunnel portal marks the eastern end of the station.

The office buildings of Prince George's Metro Center should help to narrow down this station. The parking garage stairwells are also somewhat distinctive.

Fourteen of you knew this one.

Our next view shows the escalator canopy at Dupont Circle's south entrance. Last month, I moved into my condo here, so this station will be my home station for the foreseeable future.

The main way to solve this clue is to recognize the distinctive Art Deco office building located at 1350 Connecticut Avenue. Originally built in 1928 as an apartment-hotel, it has been office since 1942. The architect, Mihran Mesrobian, also designed the Hay-Adams and Wardman Tower. We featured a similar view in week 86.

The fourth image shows the mezzanine skylight at Greenbelt, where I lived for seven years.

This skylight has been featured before, including during the very first week. Seventeen recognized this station.

The final image shows the elevator at Georgia Avenue, which has been Incorporated into the facade of a new residential building above the station's western entrance. The elevator doesn't face Georgia Avenue at a right angle because it lines up with the tunnel under the roadway leading to the mezzanine, which is itself lined up with New Hampshire Avenue.

We featured this elevator in week 58. I lived in Petworth for a year between my time at Prince George's Plaza and moving to Greenbelt.

Eleven of you came to the correct conclusion.

Great work, everyone. Thanks for playing! We'll be back in two weeks with week 114.
