The continuing demand for fast, secure and environmentally friendly traveling prompts a need for the planning and construction of high-speed rail tunnels. However, tunnels for high-speed traffic may lead to adverse aerodynamic effects for the passengers, the rolling stock and the tunnels including their equipment. The adverse consequences of high-speed rail traffic in tunnels are often enhanced by the utilization of smaller cross-sections (single track with twin-tube tunnels rather than double track with single tube tunnels) and the use of slab/concrete track instead of ballast track.

By choosing adequate civil measures, the unfavorable aerodynamic conditions in the tunnel can be reduced. Taking the concept design of the magnetic levitation link in Munich (MAGLEV) as an example, the various aerodynamic implications of high-speed traffic in tunnels and underground stations are illustrated.

The need for fast, secure and environmentally friendly traveling prompts a need for the planning and construction of high-speed public transport lines. One of these new lines planned is the magnetic levitation link in Munich running between the main rail station and the airport. The connection is about 38 km long and running at a maximum velocity of 350 km/h the total journey time is reduced to about 10 minutes. No other traffic system in Germany will be faster than the new super-speed magnetic levitation train.

n India, more than 150,000 people are killed each year in traffic accidents.

That?s about 400 fatalities a day and far higher than developed auto markets like the US.

Which in 2016 was logged about 40,000 Every day 700 vehicles hit Mumbai roads!
