<p>A light-weight body structure of a railroad car which is superior in pressure resistance, compression strength at car ends, and bending ridigity. Of a roof construction (40), a frieze panel (22), a pier panel (23), a wainscot panel (21), an underframe (30) and an end construction (50) of a body structure of a railroad car, at least the roof construction (40), the frieze panel (22), the pier panel 23 and the wainscot panel (21) are built up by outer laminate panel members (60) each comprising face plates (61, 62), a core (63), a strength member (64), a reinforcing member (65) and connecting members (66), which are all made of a light alloy and joined together by brazing. <MATH> <MATH></p> |
