Vehicle body structure and railway vehicle

A vehicle body structure and a rail vehicle, the vehicle structure comprises a roof, a chassis, a first vertical beam and a second vertical beam, the roof comprises a first closed frame and a connecting frame, the first end of the connecting frame is connected to the first side of the first closed frame, and the second end of the connecting frame is connected to the second side of the first closed frame; the underframe comprises a second closed frame and a first cross beam, the first end of the first cross beam is connected to the first side of the second closed frame, and the second end of the first cross beam is connected to the second side of the second closed frame; the first end of the first vertical beam and the first end of the connecting frame are connected to the same position of the first closed frame, and the second end of the first vertical beam and the first end of the first cross beam are connected to the same position of the second closed frame; the first end of the second vertical beam and the second end of the connecting frame are connected to the same position of the first closed frame, and the second end of the second vertical beam and the second end of the first cross beam are connected to the same position of the second closed frame. The vehicle body structure is high in torsional rigidity and bending rigidity and high in impact resistance.
