A rail system for an installation of objects in a cabin of a vehicle, having:

• a base rail,
• a floor panel,
• an installation rail, and
• connecting devices for connecting the base rail and the installation rail to one another in a mutually parallel orientation,
• wherein the base rail has a bottom side, with a securing portion for securing the base rail on a structural component of the vehicle, and a top side,
• wherein the installation rail has an installation surface on which the objects can be mounted and connected to the installation rail via the connecting devices,
• wherein the rail system is configured to position the installation surface with a predetermined spacing to the top side such that at least one lateral intermediate space is formed between the installation surface and the base rail for purposes of form-fittingly holding the floor panel, and
• wherein the connecting devices each have a bushing comprising a casing connectable to the installation rail, the casing including a circumferential collar and a cavity, the cavity including internal threads configured for threading engagement with the object being installed on the installation rail, and the circumferential collar being parallel to, and in areal contact with the installation surface of the installation rail, a lower end of the bushing having external threads which are threadedly coupled to the top side of the base rail.
