Abstract

A vehicle door for a railway vehicle and a railway vehicle includes the vehicle door include a first door skin, a second door skin and a foaming material forming a laminated structure, the foaming material being filled between the first and second door skins, wherein the first door skin has at least one folded edge portion, and the second door skin has a first bent edge portion tightly clamped in the folded edge portion in a position corresponding to each of the folded edge portions. Since during the fixing of the first and second door skins, at least part thereof is realized by a folding and clamping technique, adhesion failure risk between the door skins and a frame body is effectively lowered during use, the reliability of the fixed connection between the two door skins is improved, and the vehicle door weight and the production cost are reduced during manufacture.
