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?


Fast Fastest ground transportation system

Attractive –Comfortable – Punctual „Flying at Ground Level“

Efficient Highest possible annual performance, low LCC

Light weight Low weight per seat

Energy efficient Favorable ratio “speed – energy consumption”

Quiet Favorable ratio “speed – noise”

Environmentally friendly Good Adaption to its surroundings

Safe Failure transparent and failure tolerant

1. The Transrapid Maglev System fulfills with high percentage the following requirements for High Speed Ground Transportation Systems:

2. The Transrapid fills the gap between railway systems and air trafficwill be a high efficient supplement between railway and airplanes

For wheel-on-rail systems, the track (guideway) maintenance costs increase with operating speed. For the Transrapid system, the guideway maintenance costs are independent of operating speed.


Benefits of the Maglev System: Environmentally Friendly

Land Consumption:elevated approx. 2,1 m²/mat-grade approx. 12,0 m²/m 14 m²/m

Flexible alignment parameters with regard to gradients, curves, land consumption, route configuration

Good possibilities to collocate with highways and railroads

Noise emission(external)Same speed (200/300 km/h) of High Speed Rail and Transrapid:Transrapid has only half the noise of HS-Rail

The Transrapid fits well into the existing landscape / topography


Benefits of the Maglev System:Safety

Fully automatic transportation system

Current guideway inspection regarding geometrical deviations

Cross winds: to a high degree insensitive

Failure tolerant: Redundant concepts, to avoid safety critical conditionsFailure transparency for possible deviations of important system functions
