Abstract
A door for rail vehicle has a frame-type door main body and covering metal sheets. The door main body is formed of profiled elements, which are connected to each other by way of corner connectors. The covering metal sheets are arranged on two opposite sides of the door main body. The profiled elements are connected to each other exclusively by way of a fixed but releasable connection by the corner connectors. A fire protection material is arranged between at least one covering metal sheet and the frame-type door main body in such a way that the fire resistance and the thermal insulation of the rail vehicle door are increased.
