4 train stations have toilets, but there are other options to use in the city.
A new map from the Washington Metropolitan Area Transit Authority (WMATA) shows the locations of the four major rail stops in the DC metro area.
Each station has toilets and a public restroom.
The map shows the most popular toilet choices at each station.
For example, at the West End station, the public restroom has an area of 4.8 square feet, or 2.4 square feet per flush.
At the South Capitol station, it’s 6.4.
At Midtown, the restroom is 3.7 square feet.
At Navy Yard, the restrooms are just over 2 square feet each.
The next closest stations are Navy Yard and the Capital Beltway Station, which have just over 1.4 and 1.0 square feet of toilet, respectively.
The map is not as detailed as the other transit agency maps, but WMATA says the information is accurate and up-to-date.
The maps also show where you can get a train.
The Metropolitan Area also released an interactive map to help riders navigate the subway system.
