European Night Trains are long-distance trains that operate overnight, allowing passengers to travel between cities while they sleep. These trains typically offer various accommodations, from reclining seats to private sleeper cabins, making them a comfortable option for travelers. They connect major cities across countries like Germany, France, and Italy, providing an efficient way to cover large distances. These trains are part of a broader initiative to promote sustainable travel in Europe. By choosing night trains over flights, passengers can reduce their carbon footprint while enjoying scenic views of the countryside. Popular routes include The Caledonian Sleeper in the UK and The Nightjet service operated by ÖBB in Austria.
