Wheel - rail - problem

These problems include, for example: Wear on the contact wire, arcing on the contact wire, resulting in interference radiation, loss of material, fine dust

Limited drive power, resulting in extremely long acceleration times

Wear on the track body due to high axle loads, vibrations, point loads, high-speed loading of the material, embrittlement.

Wear and cracks on wheels, high alternating loads on the axles, high unsprung heavily loaded masses

Exorbitant noise generation due to running gear in the airflow and road contact steel on steel

.

Flawed redundancy: an axle or wheel failure at 400 km/h will result in the certain death of hundreds of people - in aviation this would never be capable of approval

.

None of the above problems currently have a solution described or announced.

Magnetic tracks, on the other hand, do not have any of the problems mentioned.

Magnetic levitation train is more viable for the future

400km/h is already too fast for conventional rails, and Germany has no topology for it. Because in order to be able to run at such speeds, it needs its own high-speed rail network, otherwise the train distances would become too great for other trains.

The magnetic levitation train (Transrapid), as well as the further development of the patented IAT-MAGLEV system   "double-deck maglev technology"  has there a much more modern concept and is also at speeds of more than 500km / h much more reliable. The technology is mature and available, it only lacks the political will to overcome outdated anti-ideologies against modern technology and progress.

A Munich company has already developed a process that makes the tracks for the Transrapid significantly cheaper. However, the political dice had already been cast, probably again mostly by sociologists, political scientists and theologians.

While for the EE the money is thrown out the window, a few billion were decisive at that time.
In the end, the rail could be partially replaced and Transrapid installed on the same route.
With reduced speed through cities, there would also be no more noise pollution.

Energy maglev train

The Transrapid consumes about 40% less energy than the high-speed ICE train at the comparable speeds. Or looked at another way: The maglev train produces about one-third more power for the same energy input.

In the IAT double-deck maglev system, an additional  600,000,-m2 of solar panels are integrated over 200 km of track, relieving energy consumption by a further 20-30%.

The energy consumption of road traffic is 5.5 times and that of short-haul air traffic more than 6 times that of maglev (at 400 km/h) for the same transport performance.
