The invention provides a boundary beam structure of a railway vehicle, a chassis, a vehicle body and the railway vehicle. The boundary beam structure comprises a boundary beam body; the lap joint part is arranged on the side, facing the inner space of the railway vehicle, of the edge beam body and extends in the length direction of the railway vehicle; wherein the lap joint part and a first floor of the railway vehicle are arranged in a lap joint mode, and the first floor and the outer surface of the boundary beam body form part of the appearance of the railway vehicle. The lap joint part in lap joint fit with the secondary floor (the first floor) is arranged on the boundary beam body, so that the secondary floor and the side, close to the bottom, of the boundary beam body form a transition structure, and the exposed part of the bottom of the railway vehicle is more attractive.

    本发明提供一种轨道车辆的边梁结构、底架、车体和轨道车辆,边梁结构包括:边梁本体;搭接部,设置于边梁本体朝向轨道车辆的内部空间一侧,且沿轨道车辆的长度方向延伸设置;其中,搭接部与所述轨道车辆的第一地板搭接设置,第一地板与边梁本体的外表面形成轨道车辆的部分外观。本发明通过在边梁本体上设置与次地板(第一地板)搭接配合的搭接部,使得次地板与边梁本体靠近底部一侧形成过度结构,使得轨道车辆底部的外露部分更加美观。
