The invention discloses a rail train and an axle box structure thereof. The axle box structure comprises an axle box body and a positioning node mounting base, wherein the axle box body adopts a split structure and comprises an upper box body and a lower box body which are in seal fit, a bearing mounting cavity is defined by the upper box body and the lower box body, the upper box body and the lower box body are connected through a bolt, and the positioning node mounting base and the upper box body are integrally formed; convex parts extending downwards are arranged on the two outer axial side edges of the lower end surface of the upper box body, downward concave parts are arranged on two outer side edges of the upper end surface of the lower box body, a first semi-circular hole and a second semi-circular hole are formed in the middles pf the upper box body and the lower box body respectively, and after the convex parts and the concave parts are buckled and sealed, the first semi-circular hole and the second semi-circular hole form the bearing mounting cavity. The upper box body and the lower box body are in split buckling and sealing connection, so that forming of the sealed bearing mounting cavity is facilitated, the reliability of bearing installation is improved, further, during wheel set dismounting, all that is required is to dismount the lower box body, a wheel set can be rapidly dismounted, and the wheel set replacement efficiency is improved.
