Street cars, also known as trams or trolleys, are vehicles that run on tracks laid along city streets. They are typically powered by electricity and are used for public transportation, helping people travel short distances within urban areas. Street cars often have designated stops and can carry many passengers at once, making them an efficient way to reduce traffic congestion. These vehicles have a long history, dating back to the 19th century, and are found in many cities around the world. Modern street car systems, like those in San Francisco or Melbourne, often feature sleek designs and integrate with other forms of public transit, such as buses and subways.
