Abstract: The coach body construction comprises an upper structure having extruded profiles, which are connected detachably to one another by corner connectors and are made of an aluminum alloy, and a lower structure. The lower structure is composed of longitudinal and transverse supports which are made of an extruded aluminum alloy and are detachably connected to one another and to the upper structure by corner connectors. In interaction with the upper structure, it is of inherently sturdy construction. The corner connectors are, in particular, screw-on corner connectors.

Abstract: A vehicle superstructure, in particular for railway carriages to transport passengers, features a structural frame formed by side and end walls and roof. This forms an outer structural plane for the carriage superstructure which is covered by an outer skin and roof cover; insulating material is fitted between the structural plane and the outer skin and roof cover. The outer skin panels are on the one hand loosely mounted via spacers hooked into grooves in sections permanently attached to the carriage frame or outer structural plane, on the other hand releasably attached via other spacers to the structural plane or held by holders secured to sections of the carriage frame with interleaving insulation.
