Lightweight stainless steel commuter train carbodies, which are currently being developed by Hitachi, are designed to reduce car weight to nearly that of aluminum alloy cars in order to save energy and to simplify maintenance by using stainless steel for all structural parts. These lightweight stainless steel carbodies have been developed for use on 20 m electric commuter train cars. The weight of the trailer carbody structures, not including the attached equipment, has been reduced to 4.5 tons. To achieve such lightweight carbody structures, the Hitachi Interactive Design System for Structure Analysis and Strength Evaluation (HIDESS) was used to determine the optimum design base, and high tensile-strength stainless steel, new structural joints, and a long flat-sheet beading technique were incorporated in fabrication.
