Sleeper cars are specialized train cars designed for overnight travel, allowing passengers to sleep comfortably during their journey. These cars typically feature private compartments with beds, bedding, and sometimes even en-suite bathrooms. They provide a more restful experience compared to standard seating arrangements. In addition to individual compartments, sleeper cars often include shared amenities like lounges and dining areas. Many long-distance trains, such as those operated by Amtrak in the United States or EuroNight in Europe, offer sleeper car options to enhance passenger comfort and convenience during extended trips.
