Commuter lines are train services designed to transport passengers between suburban areas and city centers. They typically operate during peak hours, catering to individuals who travel for work or school. These lines are an essential part of public transportation systems, helping to reduce traffic congestion and promote environmentally friendly commuting options. These services often connect with other forms of public transport, such as buses and subways, making it easier for commuters to reach their final destinations. Many cities, including New York City and Chicago, have extensive commuter line networks that serve thousands of passengers daily, enhancing accessibility and convenience.
