On Monday, we posted our second photo challenge to see how well you knew Metro. I took photos of 5 stations and we asked you to try to identify them. Here are the answers. How well did you do?

We got 23 guesses on this post. One commenter, Justin, got all 5 correct. Excellent work, Justin! Another 4 commenters got 4 right.

Image 1: Silver Spring.

Over 75% of you got the first one right. This is an inbound Red Line train arriving at Silver Spring. You can see the Lenox Park residential tower in the upper left corner, which seemed to help several of you find the answer.

Image 2: Braddock Road.

The second image is a picture of Braddock Road, taken from a southbound Amtrak train. Only 5 of you got this one right, but most people made educated guesses based on the railroad tracks visible in the foreground. I thought this one would be easy, since Braddock Road and King Street are the only two stations with this roof design (3 people guessed King Street).

While WMATA does have a few unique stations, most fall into 8 basic designs. Knowing which design elements are present could help you get the right answer in the future. The devil (and the answer) is in the details.

Image 3: Gallery Place.

The third image is of the lower level of Gallery Place. Eight of you guessed correctly. Another six guessed either Metro Center or L’Enfant Plaza, which were also great guesses, since the three downtown transfer stations have a similar layout.

One commenter, Justin, gave his reasoning for picking Gallery Place over the other two:

It’s underground transfer, which makes it Gallery Place, Metro Center, or L’Enfant Plaza. There’s a red transfer dot, eliminating L’Enfant Plaza. There are four lines of text on the wall, and the second line is small. If it was Metro Center, the second line on the Virginia side would be longer for Silver Line, and there wouldn’t be one on the Maryland side, since Silver/Blue both go to Largo.

Image 4: New Carrollton.

This picture is of the eastern entrance to New Carrollton. One distinct feature of this station is the extra-wide overhang on this side of the station. It’s the result of a provision for a bypass track into the railyard here that was never installed. Six of you got this one.

Image 5: Greenbelt.

This one did prove to be the hardest: only four of you got it right. But I’m impressed. Everyone gave it a good go and made educated guesses.

This is a sign at Greenbelt in the pedestrian tunnel that links the faregates to the Lackawanna Street entrance and the MARC Camden Line platforms. At Greenbelt, the Camden Line platform for Baltimore (eastbound) is only accessible from this tunnel. The only other place where that happens is in Rockville (2 of you guessed Rockville).

At New Carrollton (3 guesses) both MARC tracks are on an island platform, so there’s no need to distinguish between directions. Silver Spring (2 guesses) does have split tracks, but both are accessed from a bridge that is off WMATA property.

I think one thing that threw people off was the “westbound.” But remember that MARC (and before it, the B&O) considers both the Camden and Brunswick lines to run east-west. Baltimore is railroad east of Washington and Brunswick is railroad west. If you pull up a Camden or Brunswick line schedule, you’ll see they refer to trains as eastbound and westbound.

Next Monday, we’ll have 5 more photos for you to identify. If you want a sneak peek, you can follow me on Instagram. Thanks for playing!
