Grip cars are also known as "cable cars," "streetcars," or "tram cars." These types of cars are designed to "grip" onto an overhead cable, usually made of steel, to propel the car forward. In addition to these common synonyms, more specific terms can be used depending on the location or type of grip car. In San Francisco, they are called "cable cars," while in other cities they may be referred to as "trolleys" or "light rail vehicles." Whatever the name, grip cars remain an important mode of transportation in many cities, providing both practical travel and a unique experience for tourists and locals alike.
