The sidewall of a train is the lateral part of the roof or support to which the windows and / or entrance doors are integrated.
Depending on the design, the sidewalls can be made of steel or light alloy materials.
If the length of the sides is noticeable, as occurs in vehicles with three axles or carriages, the sidewalls are built as beams, that is the sections are reinforced with struts and tie rods.
If the sidewalls are of limited length, instead, as in nominal two-sided vehicles; they are designed to keep the rooms in an invariable position with respect to the frame, allowing only vertical displacements.
From the first stages of production to the final inspection, CIM creates sidewalls for railway carriages of all kinds, placing the utmost attention in terms of quality and safety in full compliance with all customer requirements.
