Capital Bikeshare stations range in size, from nine docks to 47 docks. Here are photos of the smallest station (a secret station!) and the five biggest.

First, the smallest station: the White House secret station. It’s got nine docks, and sits behind a fence at 17th Street and State Place NW, just south of the Old Executive Office building.

The station is not open to the public and does not appear in Capital Bikeshare’s data feed. It’s also an anomaly for its size: 81 stations, each with 11 docks, are tied as the second-smallest stations in the system.

Now, the biggest stations, starting with a three-way tie for third place:

3rd-biggest (tie): 12th Street & Independence Avenue SW, next to the USDA buiding (39 docks)

This station sits close to the Smithsonian Metro station’s south exit and is likely popular among tourists and office workers alike.

3rd-biggest (tie): Maryland & Independence Avenues SW (39 docks)

Farther east on Independence Avenue is this 39-dock station, placed in the median of Maryland Avenue SW, which is slated to become the future Eisenhower Memorial. This station is the closest one to the Smithsonian Air and Space Museum, the third most-visited museum on the planet.

3rd-biggest (tie): Nationals Park / 1st & N Streets SE (39 docks)

It’s no surprise Nationals Park is a huge trip generator. This station likely saw even higher demand than usual when WMATA decided to keep with its early closing schedule during the Nationals’ playoff games.

2nd-biggest: Massachusetts Avenue & Dupont Circle NW (45 docks)

The second-biggest station sits at Massachusetts Avenue and Dupont Circle NW.  The docks are split between two parallel rows.  Located in a neighborhood populous with both residences and offices, it’s no surprise this station is the system’s second-busiest.

Biggest station: Union Station (47 docks)

Capital Bikeshare’s biggest and busiest station resides at Union Station, a multimodal transportation hub serving 40 million visitors a year.  The 47-dock station stretches along Columbus Circle NE near the east fa├žade of the station and lies at the end of a contraflow bike lane that runs on F Street NE.
