On Tuesday, we posted our forty-seventh photo challenge to see how well you know Metro. I took five photos in the Metro system. Here are the answers. How well did you do?

This week, you must have all been out looking for the first 7000 Series train instead of playing whichWMATA, because we only got 12 guesses. Two of you got all five. Great work, Peter K and Justin….!

Image 1: Spring Hill

The first image shows the view from the western entrance bridge to Spring Hill station. The mesh grating and new concrete viaduct make it clear that this is a Silver Line station. The configuration of the roadway, with the tracks in the median rather than off to one side, means that this is either Greensboro or Spring Hill. And you can narrow this down to Spring Hill because the bridge here is lower than the tracks rather than above them, which is the case at Greensboro. Nine of you got it right.

Image 2: Shady Grove

The second image shows the stair/escalator at Shady Grove; the first appearance of this station in the series. I thought this one was fairly obvious. The “next train” indicator means this is an end-of-line station. There are only two such stations with gull I roofs. And only Shady Grove has a staircase sandwiched between two escalators. Ten knew this one.

Image 3: West Hyattsville

The third image shows the south end of West Hyattsville station, viewed from the Northwest Branch Trail. The twin blockhouses that protrude into the top of the image indicate that this is a side platform station. The concrete structure in the foreground is a traction power substation (which provides electric power to the third rail). Few stations have these attached directly to the station (though many have one nearby).

The real clue here is the unique architecture of West Hyattsville (featured in week 8). But the park-like setting was also a clue. Only six of you guessed correctly.

Image 4: Federal Center SW

The fourth image was also a first-time whichWMATA station: Federal Center SW. The distinctive feature here is the green tile surrounding the opening. It accents the building, which houses the entrances to the station. The building itself takes up the entire block surrounded by 3rd Street, D Street, 4th Street, and Virginia Avenue SW. This particular photo shows the alcove housing the elevator. Four people got it right.

Image 5: Forest Glen

The final image proved hardest. Only two people got it right. It shows the Coleridge Drive/Georgia Avenue entrance to the Forest Glen station. The main entrance faces the bus loop and parking lot, but this entrance gives passengers a straight shot to the pedestrian bridges over the Beltway ramps south of the station.

The unique feature here is the metal grating above the staircase. The grating is in place because the staircase can be closed off with an odd curved grate at the top of the stairs. It prevents people from being able to climb down into the station when the gate is closed. It’s unique in the system, but if you haven’t used Forest Glen you’d probably be hard-pressed to recognize it.

Thanks to everyone for playing! Great work. Stay tuned. We’ll have five more images for you next week.
