A sleeper ticket refers to a specific class of train travel that provides a dedicated bed or "berth" for overnight or long-distance journeys. In 2026, these tickets are the cornerstone of the "slow travel" movement, offering a hotel-on-wheels experience. Depending on the country, a sleeper ticket can range from a "Couchette" (a simple shared compartment with 4–6 fold-down bunks) to a "Sleeper Cabin" (a private room with 1–2 beds, often including a private sink or even a shower). In India, "Sleeper Class" (SL) is a more budget-friendly, non-air-conditioned reserved coach with three tiers of bunks, whereas in Europe and the US, a sleeper ticket usually denotes a more premium, private experience. These tickets often include added perks like bedding, breakfast, and access to a lounge at the station. For many travelers, a sleeper ticket is a highly efficient way to travel, as it combines the cost of transportation and a night's lodging, allowing you to go to sleep in one city and wake up refreshed in a destination hundreds of miles away the following morning.
