Abstract

A side wall for a rail vehicle body includes an outer skin, an insulating layer adjacent an inner face of the outer skin, a structural layer adjacent an inner face of the insulating layer, a finishing layer adjacent an inner face of the structural layer and a window. The insulating layer provides at least one of a thermal and an acoustical insulation. The structural layer has a longitudinally aligned top door frame member, vertical left and right door frame members and a plurality of diagonal structural members oriented at an angle comprised between 1 degree and 89 degrees from the top door frame member. The plurality of diagonal structural members defines a lattice structure having a plurality of openings there in between. The window covers at least a portion of one of the plurality of openings.
