A wagon has two side walls, two end walls and a base. At least a portion of one or each side wall has two side wall parts in the form of panels. Each panel has a respective constant wall thickness and is joined together. In some embodiments, the panels can be integrally formed. The side wall panels are also each of a different material thickness. A bridging member in the form of an angled bracket is arranged to interconnect the respective side wall panels by being separately connected to each side wall panel.

1. A railway wagon for carrying bulk materials, the wagon comprising two side walls, two end walls and a base, at least a portion of one or each side wall comprising two discrete side wall parts, wherein a bridging member is arranged to interconnect the respective side wall parts by being connected to each side wall part at locations vertically spaced apart on the side wall, the bridging member being elongate and arranged in use to extend at least part way along a respective side wall from one end wall to an opposing end wall, the bridging member being in the form of a stiffening bracket having two or more mutually inclined parts in cross section, a top edge and a bottom edge and being connected to the side wall parts only at the top and bottom edges of the bridging member so that the top edge is connected to a side wall part and the bottom edge is connected to another side wall part. 2. The wagon according to claim 1, wherein each side wall part is formed as a panel having a respective constant wall thickness and the two side wall parts are joined together, the bridging member is not part of any of the side wall parts and is disposed inside the wagon, the side wall parts are each of a different material thickness and are aligned in common plane or in parallel planes, the two side wall parts are disposed one above the other, and the lower side wall part has a greater material thickness than the upper side wall part. 3. The wagon according to claim 2, wherein the two side wall parts partially overlap and are joined at the overlap. 4. The wagon according to claim 3, wherein the join at the overlap is achieved by means of a weld. 5. The wagon according to claim 4, wherein the weld is stitch weld. 6. The wagon according to claim 2, wherein distal end regions of the bridging member are welded to the respective ones of the side wall parts. 7. The wagon according to claim 6, wherein the weld between each of the distal ends of the bridging member and the side wall parts in a continuous weld. 8. The wagon according to claim 2, wherein the bridging member incorporates first and second mutually inclined parts. 9. The wagon according to claim 8, wherein the bridging member has an L-shaped profile in cross-section. 10. The wagon according to claim 2, wherein the bridging member is positioned so as to face an interior of the wagon, said interior being the region bounded by the side walls, end walls and base. 11. The wagon according to claim 2, wherein the bridging member extends along said wall intermediate upper and lower ends of said side walls. 12. The wagon according to claim 2, further comprising a capping joined to one of said wall parts so as to form at least part of an upper edge of said side wall, and a second bridging member arranged to interconnect said capping and said wall part. 13. The wagon according to claim 2, further comprising a capping that forms at least part of an upper edge of said side wall. 14. The wagon according to claim 12, wherein the capping has a first portion that is joined to the panel and a second portion that is angularly disposed from the first portion. 15. The wagon according to claim 13, wherein a second bridging member extends from the second portion to the panel so as to form a closed section at an upper edge of the side walls. 16. The wagon according to claim 12, wherein the capping has an L-shaped profile in cross-section positioned atop the side wall panel and at a rim of an opening to the interior of the wagon. 17. The wagon according to claim 2, wherein the bridging member forms a stiffener for the side wall.
