Abstract
The invention relates to a rail vehicle body of the type comprising a grid structure, itself comprising longitudinal elements and cross elements interconnected at nodes, and supporting outer and inner coverings. Longitudinal and cross elements are circular section tubes. At at least some of its nodes, the grid structure comprises connections for interconnecting longitudinal and cross tubes of circular section. These connections have longitudinal and cross circular section sleeves which receive longitudinal and cross tubes respectively. Longitudinal tubes pass right through the connections made of longitudinal and cross tubes.
