Market Mobility Actual Situation High Growth High Growth Less Growth Growth Ground Air Road traffic (cars buses) Pressure Railway systems Pressure Domestic flights Long distance flights In all industrial countries, in all growing national economies, the modal split should be changed in favour for track bound systems. Competitive factors are therefore decisive such as Attractiveness Efficiency Speed Environmental Friendliness Safety Will a new track bound transportation system the Maglev system Transrapid fulfill these requirements?
