On Tuesday, we posted our forty-second 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, we got 23 guesses, and over half of you got all five. Excellent work, Alex B, Doug, JamesDCane, Peter K, Robb, Fran, MZEBE, Justin…, FN, RyanS, Mr. Johnson, Spork!, and R2-JL.

Image 1: Greensboro

I took the first image at Greensboro station (on opening day, in fact). You should have been able to narrow this down to one of the five Silver Line stations immediately based on the architectural features. The pedestrian bridge and entrance in the distance is typical of those stations. The triangular window in the canopy also tells you that this is one of the three “gambrel” stations. Finally, the tower in the distance should have told you this was in the Tysons area. Eighteen of you knew this one.

Image 2: Silver Spring

These icicles are hanging from the canopy at Silver Spring. There are two primary clues here. The first is the PIDS (next train) sign. You can see two “no passenger” trains on either side of a Glenmont train. That should have clued you in that this was Silver Spring, where Grosvenor — Silver Spring trains terminate.

But in case that wasn’t enough, I included another hint: the “Metro Plaza” sign on the building in the distance. Sixteen people got this one right.

Image 3: Vienna

The third image shows the northern parking garage at Vienna station. As a few of you noted, there aren’t many stations with multiple garages, so that narrowed the field considerably. This garage is on the north side of I-66 and is fairly distinctive. Sixteen of you figured it out.

Image 4: Braddock Road

The fourth image shows a northbound train approaching Braddock Road station. There were a few clues to help you get this one. The buildings in the distance, combined with the ground-level track, mean it’s definitely in Alexandria. Some of you may have even recognized a few of the buildings. Also, the overpass immediately beyond the station (Braddock Road itself) should have helped you narrow this one down. Eighteen of you were successful.

Image 5: College Park

The final image didn’t give you a lot to go on, but there was still enough. You can see that it’s a Green Line train from the light on the front. The station has an island platform and is at ground-level, a setup you can only find at five Green Line stations. The adjacent parking garage eliminates Greenbelt, Suitland, and Branch Avenue. And the platform at Southern Avenue is in an open cut, so you can’t see the garage there from the platform. That leaves College Park. Eighteen of you made the connection.

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