Abstract: A catering assembly for use with an aircraft or train includes a wall (1) provided with a multiplicity of slots (2) running in the vertical direction with undercuts as well as a multiplicity of essentially block-shaped modules (6) with runners (14) on the rear that can be accommodated in the undercut slots (2), the cross-sectional shape of which, viewed in the horizontal plane, corresponds to the cross-sectional shape of the undercut slots (2), viewed in the horizontal plane. The catering assembly furthermore includes lifting elements for raising or lowering the module (6), the runners (14) of which have been accommodated in a the undercut slot (2), over the wall. It is preferable if the slots (2) are widened in places (15) such that a runner (14) can be inserted here in the horizontal direction so as then to hook into the undercut slot (2) after being moved vertically.
