The invention discloses a vehicle body structure and a railway vehicle. In the vehicle body structure, the size of the cargo inlet/outlet along the length direction of the vehicle body is greater than 3m; the first frame provided with the cargo inlet and outlet comprises a traction beam, a lower side beam and a traction beam which are sequentially connected in the length direction of the vehicle body, the middle section area of the lower side beam limits the lower boundary of the cargo inlet and outlet, the lower side beam is in a channel steel type, an opening of the channel steel type lower side beam faces the first frame on the opposite side, and the upper boundary of the channel steel type lower side beam is horizontally arranged. The size of the middle area of the channel steel type lower side beam in the height direction of the vehicle body is larger than that of the two ends of the channel steel type lower side beam in the height direction of the vehicle body, and a section with the size monotonically increasing in the height direction of the vehicle body does not exist from the position, with the largest size in the height direction of the vehicle body, of the channel steel type lower side beam to any end area. The first frame on the side provided with the goods inlet and outlet further comprises a lower side beam inner sealing plate for sealing an opening of the channel steel type lower side beam. The device is suitable for transportation of large-size goods.
