COMFORT AND STABILITY

A fast passenger train needs to offer a comfortable ride to the people inside. Attraction between magnets at the edges of the guideway and under the L0 keeps the train stable as it glides along. This effect grows stronger as the train moves faster, because the magnetic force is induced in the guideway by the approaching train.

The repulsion that keeps the EDS maglev in the air also increases the faster it goes. In fact, the force is too weak to lift up the train at low speeds. That is why the L0 leaves and arrives back at stations on rubber wheels. The wheels automatically fold up beneath the train when it speeds above 93 miles (150 km) per hour and fold down again when it slows. The wheels also deploy if power to the train is cut during an emergency, so it can come to a halt safely.

CUTTING EDGE

In Switzerland, engineers and designers planning a national maglev high-speed rail network have figured out a way to reduce drag even further. They plan to pump out the air from the tunnels containing the maglev guideways as they wind through the country’s mountains. With little air in tunnels, speeds could hit 621 miles (1,000 km) per hour!
