Rail and public transportation systems are essential for moving people and goods efficiently within cities and between regions. These systems include trains, subways, buses, and trams, which provide affordable and accessible travel options. They help reduce traffic congestion and lower carbon emissions, contributing to a more sustainable environment. Public transportation networks often connect with rail services, allowing for seamless travel across longer distances. Many cities invest in expanding and modernizing these systems to improve service reliability and increase ridership. By offering a variety of transportation options, communities can enhance mobility and support economic growth.
