A gondola railway car with a structural frame of metal has panels of lightweight composite tension-bearing sheet material attached to the frame by clamps which grip the margins of the panels. The panels thus are structural components of the car body, while also acting to contain bulk cargo such as coal. The panels may be of aramid fiber cloth coated with a wear-resistant polymeric material, and particles of hard material may be embedded in the polymeric material to enhance resistance to mechanical erosion.

Wagon-tombereau de train à structure métallique. Ce wagon présente des panneaux constitués d'un matériau en feuille composite capable de supporter une tension, les panneaux étant reliés à la structure par des crampons qui pincent les bords des panneaux. Ces derniers agissent donc comme composants structuraux de la caisse du wagon, mais ils sont également conçus pour contenir du fret en vrac, par exemple du charbon. Ces panneaux peuvent être fabriqués en un tissu de fibre aramide enduit d'un matériau polymérisé résistant à l'usure, des particules de matériau dur pouvant être incorporées au matériau polymérisé pour améliorer sa résistance à l'érosion mécanique.
