The invention discloses a rail wagon with a chassis unit, a center beam unit, a top frame unit and end walls. The rail wagon comprises a wagon body, wherein the wagon body comprises the chassis unit, the center beam unit, the top frame unit and two groups of end walls; wherein the bottom frame unit is arranged below the top frame unit, and the bottom frame unit and the top frame unit are arranged in parallel; the cross section of a structure formed by the bottom frame unit, the center beam unit and the top frame unit is in an I shape, and the transverse width of the top frame unit is smaller than that of the bottom frame unit; and two end walls are arranged at two ends, in the longitudinal direction of the vehicle body, of the top frame unit and the bottom frame unit correspondingly. Under the condition of ensuring rigidity of the vehicle body, the self-weight of the vehicle body can be reduced, the bearing capacity is improved, and goods are convenient to load and unload.
