High Speed Rail

Why is high-speed rail considered a more sustainable mode of transportation compared to cars and airplanes?

• It uses magnetic fields to move.

• It can transport more people at once, reducing the carbon footprint per passenger.

• It operates only on solar energy.

• It is completely silent, reducing noise pollution.
