 The AeroLiner3000 proposal has set itself the goal of investigating a double-decker high-speed train following the HS2 Classic Compatible Train Specifications 2012.The resulting concept is a 200 m trainset, with 20 m long end cars and 17 m long intermediate car, each with four individually powered and controlled wheels at the very end to form an innovative virtual Jacobs-bogie.The axle loads are 17 t. The cars' construction consists of continuously bent equal diameter steel tubes which are laser welded, achieving an extreme lightweight construction, which becomes also apparent in the large windows with their very slim diagonal posts.
