The Cable Cars in San Francisco
    The streets are steep in San Francisco. They run uphill and downhill at angles astonishing to a newcomer. A few of this steepest streets have a unique means of transportation called cable cars.
    A cable car is tall and clumsy compared to a modern bus. It is pulled up and down hill by a steel cable under the street. Cable cars are a survival from the days before electric power.
    The front section of the car is open to the weather at all times. The passengers in this section sit parallel to the sidewalk. Timid newcomers hold onto a pole to keep from sliding into the street. Athletic young San Franciscans jump onto the narrow rinning board without waiting for the cable car to stop. (The maximum speed of a cable car is nine miles an hour.) At the end of the line, the passengers get out and help the motorman push the car around on its revolving platform for the return trip.
    The cable cars are more expensive to run than buses. They create a deficit for the city every year. San Francisians like them and keep them anyway.
