Suburban rail refers to train services that connect urban centers with surrounding suburban areas. These trains typically operate on dedicated tracks and provide a reliable mode of transportation for commuters traveling to and from work, school, or leisure activities. Suburban rail systems are designed to reduce traffic congestion and promote environmentally friendly travel options. Many cities around the world have developed their own suburban rail networks, such as the Metra in Chicago and the S-Bahn in Germany. These systems often feature multiple lines, frequent service, and convenient stations, making it easier for residents to access urban amenities without relying on cars.
