A streetcar system is a form of public transportation that uses rail vehicles, known as streetcars or trams, to transport passengers along designated routes within urban areas. These vehicles typically run on tracks embedded in city streets and can operate alongside other traffic. Streetcar systems are designed to provide efficient and accessible transit options, often connecting key destinations like residential neighborhoods, business districts, and cultural sites. Streetcars are powered by electricity, usually supplied through overhead wires, and can be a sustainable alternative to cars. Many cities, such as San Francisco and New Orleans, have revitalized their streetcar systems to enhance urban mobility and reduce traffic congestion. These systems can also promote economic development by attracting visitors and businesses to areas served by the streetcars.
