The invention discloses a railway vehicle body chassis structure and a railway vehicle, and relates to the technical field of railway vehicles. Two layers of sleeper beams are arranged in the underframe structure, and the end of a sleeper beam top layer structure and the end of a sleeper beam bottom layer structure are arranged in a stepped mode. A wiring channel is arranged in the middle of the top of the sleeper beam, and a cover plate is detachably arranged on the top of the wiring channel and used for sealing a top opening of the wiring channel. The first end of the first floor in the floors is provided with an installation space, the sleeper beam and the traction beam are embedded in the installation space, and structures on the two sides of the installation space are in lap joint with the top of the sleeper beam and the top of the traction beam. Wiring channels arranged in the longitudinal direction are formed in the two sides of the first floor, and openings are formed in the top wall and the bottom wall of each wiring channel. Opposite side walls of the installation space are provided with openings communicated with the wiring channel and the wiring channel. The sleeper beam is arranged at the end of the traction beam, and the top face of the traction beam, the top face of the sleeper beam, the top face of the first floor and the top face of the cover plate are coplanar. The underframe is high in structural strength and rigidity and has sufficient installation space.
