Night trains are passenger trains that operate during the night, allowing travelers to sleep while they journey to their destination. These trains often feature sleeping compartments, reclining seats, and dining cars, making long-distance travel more comfortable and efficient. Traveling by night train can save time and money, as passengers can avoid the cost of a hotel stay. Many countries, including Europe and Japan, have well-established night train services, connecting major cities and scenic routes, providing a unique travel experience while reducing daytime travel congestion.
