The next type of streetcar was the cable car, which sought to reduce labor costs and the hardship on animals. Cable cars are pulled along a rail track by a continuously moving cable running at a constant speed on which individual cars stop and start by releasing and gripping this cable as required. The power to move the cable is provided at a site away from the actual operation. The first cable car line in the United States was tested in San Francisco, California in 1873.

Cable cars suffered from high infrastructure costs, since a vast and expensive system of cables, pulleys, stationary engines and vault structures between the rails had to be provided. They also require strength and skill to operate, to avoid obstructions and other cable cars. The cable had to be dropped at particular locations and the cars coast, for example when crossing another cable line. After the development of electrically-powered streetcars, the more costly cable car systems declined rapidly.

Cable cars were especially useful in hilly cities, partially explaining their survival in San Francisco, though the most extensive cable system in the U.S. was in Chicago, Illinois, a flat city. The San Francisco cable cars continue to perform a regular transportation function, in addition to being a tourist attraction.
