The article focuses on a project in the Centre for ECO Vehicle Design at the Royal Institute of Technology in Stockholm, Sweden which examines the economic and environmental benefits of lighter high speed trains with the use of multi-functional body panels based on composite and sandwich technologies to reduce the weight of the bodyshell. The benefits of such panels include simplification of the manufacturing process and achievement of reduced wall thickness. Concerns about lighter vehicles include crosswind safety and crash safety issues.
