A self-closing door assembly has a curved sliding door (Fig.1,140) which moves along a curved path between open (Fig.2B) and closed (Fig.2A) positions. A number of diverters 240 are arranged along the path of the door for guiding a connector 220 such as a cable; the connector has a first end connected to a spring device 210, such as a spiral spring or helical spring (fig.4A,260), and a second end connected to the door; the spring device is tensioned when moving the door towards the open position and acts as a closing mechanism to move the door into the closed position. A damper 230 is engaged with the connector, limiting its movement when pulled by the spring device during door closing. Preferably, the spring device, diverters, and damper are attached the ceiling (Fig.1,110) of a railway vehicle toilet cabin (Fig.1,100), with the connector attached to an upper end of the door. A kit is also claimed which may also contain a timer 250 to keep a sliding door in an open position for a predetermined time, releasing it once the time has elapsed, and a safety element 270 for stopping door movement.
