Passenger trains are vehicles designed to transport people from one location to another along railway tracks. They typically consist of multiple carriages or coaches, which can include seating areas, dining cars, and sleeping compartments. Passenger trains are an efficient and eco-friendly mode of transportation, often used for both short and long-distance travel. These trains operate on scheduled routes and can vary in speed and comfort. Some well-known types include commuter trains, which serve urban areas, and high-speed trains, which connect major cities quickly. Passenger trains are an essential part of public transportation systems in many countries around the world.
