The streetcar industry refers to the system of public transportation that uses streetcars, also known as trams or trolleys, to move passengers along urban routes. Streetcars typically run on tracks embedded in city streets and are powered by electricity, making them an efficient and environmentally friendly option for urban transit. Historically, the streetcar industry played a significant role in the development of cities, facilitating urban growth and shaping neighborhoods. Many cities, such as San Francisco and New Orleans, still operate streetcar systems, while others have reintroduced them to reduce traffic congestion and promote sustainable transportation options.
