Regional rail services are train systems that connect smaller towns and cities within a specific area, providing an essential mode of transportation for daily commuters and travelers. These services typically operate on shorter routes compared to national or intercity trains, making them more accessible for local residents. These trains often run at frequent intervals and may include amenities such as comfortable seating and onboard services. Regional rail services are crucial for reducing road congestion and promoting sustainable travel, as they encourage people to use public transport instead of driving.
