The invention provides a railway vehicle and a roof thereof. Sunken installation of a current collector and an air conditioner can be achieved, the influences on a roof streamline structure are reduced, air resistance and aerodynamic noise are lowered, and the aerodynamic performance of a train is improved. The roof comprises multiple transversely-spliced hollow section bars, longitudinally-stretching chutes are formed in the bottom faces of the hollow section bars, and an installation part of built-in equipment is formed. The roof is provided with an air conditioner installation seat, a pantograph installation seat and a high-voltage equipment box which are all embedded in the roof, and the tops of the air conditioner installation seat, the pantograph installation seat and the high-voltage equipment box are each in an arc shape matched with the roof. The roof is formed by splicing the hollow section bars, the chutes are formed in the bottom faces of the hollow section bars, when needed, the built-in equipment enters the roof from the chutes in the roof, and the equipment is hoisted on the roof. The air conditioner installation seat, the pantograph installation seat and the high-voltage equipment box are all embedded in the roof, smooth design of the surface of the roof is achieved, and the aerodynamic performance of the train is effectively improved.
