Commuter trains are passenger trains that primarily transport people between their homes and workplaces, often in urban or suburban areas. They typically operate on a fixed schedule and cover shorter distances compared to long-distance trains. Commuter trains are designed to accommodate daily travelers, providing a reliable and efficient means of transportation. These trains usually run during peak hours, making stops at various stations to pick up and drop off passengers. Many cities have established commuter rail systems, which help reduce traffic congestion and promote environmentally friendly travel. Examples of such systems include the Metropolitan Transportation Authority (MTA) in New York City and Metra in Chicago.
