The invention provides a railway wagon body and a bottom door locking mechanism, wherein the bottom door locking mechanism can improve the bottom door locking reliability, is flexible and convenient to operate, and reduces time and effort. The bottom door locking mechanism comprises a rotating shaft extending from front to back, a plurality of locking members arranged on the rotating shaft, and a handle connected with the rotating shaft, and further comprises a supporting member, wherein the handle extends upward obliquely from the inside out in the transverse direction; the lower end of the handle is fixedly connected with the rotating shaft; the upper end of the handle can rotate around the lower end, so as to drive the rotating shaft to drive each of the locking members to lock or unlock the corresponding bottom doors; when the handle is rotated up to a first predetermined position, the locking members are driven to lock the bottom doors, the supporting member can support the handle, to overcome gravity of the handle and lock the handle. No strict cooperation relation exists between the supporting member and the handle, even if the rotating shaft is deformed due to long-time use, the positioning reliability of the handle also can be ensured, so as to ensure the locking reliability of the bottom doors.
