AC 2-tier is a class of air-conditioned sleeping car in Indian Railways. It has four berths arranged in two-tiers facing each other in a single bay with two-tiered berths arranged on the sides lengthwise across the corridor for a total of 46 to 54 berths per coach.
AC 2-tier coaches have wider sealed windows and are more comfortable than AC 3-tier coaches, but the tickets can be relatively pricey.
