The invention discloses a modular railway vehicle body. The vehicle body comprises a vehicle roof, side walls, a bottom frame, end walls and a cab framework. The roof adopts a full-length arc roof structure; the side wall is of an integral structure or a split structure, and the side wall is mainly composed of a side wall top profile and a plurality of side wall units. Each side wall unit is formed by assembling and welding a plurality of parallel door stand columns and side wall plate sectional materials, and the extending directions of the door stand columns and the side wall plate sectionalmaterials are perpendicular to the side wall top sectional materials. The bottom frame is mainly composed of bottom frame edge beams, floor middle profiles, sleeper beams, traction beams and anti-side-rolling installation bases. The roof and the side walls, the underframe edge beams and the floor edge section bars, and the floor edge section bars and the floor middle section bars are connected through lap joints or butt joint joints. According to the vehicle body, through the design of the top layer, the vehicle body structure and the section bar section are optimized, and the universality and the sharing rate are improved.
