The National Capital Trolley Museum, operated by a private nonprofit organization is located in M-NCPPC’s Northwest Branch Recreational Park. The museum opened to the public in 1969. Its mission includes preserving and interpreting the history of Washington’s electric street railways.
The museum maintains a collection of streetcars from Washington and other cities, and operates many on a mile-long demonstration railway. In addition, the museum features an O-scale model layout depicting a Washington streetscape from the 1930s, a film program, and traditional exhibits of street railway artifacts and photographs.
