Streetcars to return soon to the District | Gallery – The Post
The last street car in Washington, D.C. stop running 50 years ago this past Saturday. That system had been in decline following World War II. Street cars served the nation’s capital for a century. The Smithsonian‘s National Museum of American History‘s On the Move Exhibit Web site has a feature called “A Streetcar City” about Washington’s street cars.

Street cars are expected to return to D.C. in the next few years with tracks being installed on H Street NE and in Anacostia.

If you want to see what the old-time street cars were like, head up to National Capital Trolley Museum in Colesville, Md. I went once as a kid and will probably be going again this spring. The FAQ is also worth reading because it explains that traditionally it was “street cars” in Washington, instead of “streetcars.” It seems that custom is no longer observed, though I’ll do it. The difference between trolley, street car and light rail is also explained.

Lastly, the Wikipedia page on D.C. Street cars is very informative.
