The DLR Institute of Vehicle Concepts in Stuttgart developed the concept, which is part of the extensive research being conducted in the Next Generation Train (NGT). The aim of the project is not only to reduce travel time, but also to make rail transport safer, more comfortable and more environmentally friendly. Lightweight designs and construction play a key role in achieving these objectives – the mass of rail vehicles has a direct impact on energy consumption due to driving resistance. Less weight has a positive impact on cost and environmental factors. Therefore, DLR engineers want to build the lightest possible wagons. This means that a new crash concept is also needed.
