A Presidents' Conference Committee (PCC) car is a type of streetcar (tram) that was first built in the United States in the 1930s. The design proved successful domestically, and after World War II it was licensed for production and use elsewhere in the world.
The PCC car has proved to be a long-lasting icon of streetcar design. About 5,000 PCC streetcars were built in the United States, with production continuing until 1952. In North America, some PCC streetcars are still in regular service, with most operating on heritage streetcar lines. As of 2026, the San Francisco Municipal Railway is the largest North American operator of PCC cars, using a fleet of 27 on two heritage lines.
After World War II, the PCC design was licensed to multiple European companies.
