The invention provides a track traffic vehicle with sleeping berths. The track traffic vehicle with sleeping berths is composed of a passenger room, an under vehicle part and an up vehicle part, wherein the space inside the passenger room is divided into three relatively independent spaces, i.e., a left space, a right space and a middle space, along the width direction of the vehicle; the middle space is a channel; the left space and the right space are provided with a row of partitions respectively; two layers of beds are arranged in each partition; the beds in adjacent partitions are staggered along the length direction of the room; each bed is independently and correspondingly provided with a tea table, a window, a lighting system and an air-conditioner heating facility. As the beds are distributed along the length direction of the passenger room, the safety and comfort level of passengers are improved; meanwhile, as the two layers of beds are staggered on the two sides of the channel in a manner of four rows, the fixed quantity of the passengers is close to the fixed quantity of three layers of the beds, and the economical efficiency of the vehicle with the sleeping berths is improved greatly; furthermore, each bed form a relatively private space by using each partition wall, and independent windows and tea tables are arranged in the partitions, so that passengers are convenient to move, and go up and down the beds, and the level and comfort of the vehicle with the sleeping berths are improved.
