Abstract: The invention relates to a system for rail-bound transport of objects, the system comprising a plurality of railway cars (11) that can be coupled together, each having at least one transport track (26, 27) provided on a support structure (20), on which the objects can be moved along the railway cars (11). The system is designed such that the transport tracks (26, 27) of coupled railway cars (11) adjoin one another, wherein transport bodies (28) for the objects are provided, which are designed for moveability along adjoining transport tracks (26, 27) from railway car to railway car, or wherein the objects are piece goods and themselves constitute such transport bodies. The support structures (20) are each a loadable unit (15) or are housed in a loadable unit (15), wherein each of the loadable units(15) can be detachably fixed to the associated railway car (11).
