How is a maglev train designed?
The engine for maglev trains is rather inconspicuous. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combine to propel the train. If you’ve ever played with magnets, you know that opposite poles attract and like poles repel each other.
What materials are used to make a maglev train?
Magnets made from rare-earth elements, however, produce a stronger magnetic field than ferrite (iron compounds) or alnico (alloys of iron, aluminum, nickel, cobalt, and copper) magnets to lift and guide the train cars over a guideway.
Where was the first maglev train system built?
Several train systems using maglev have been developed over the years, with most operating over relatively short distances. Between 1984 and 1995 the first commercial maglev system was developed in Great Britain as a shuttle between the Birmingham airport and a nearby rail station, some 600 metres (about 1,970 feet) away.
What makes a maglev train faster than a regular train?
Maglev trains eliminate a key source of friction —that of train wheels on the rails—although they must still overcome air resistance. This lack of friction means that they can reach higher speeds than conventional trains. At present maglev technology has produced trains that can travel in excess of 500 km (310 miles) per hour.

What are the environmental impacts of maglev trains?
Environmental Impact: Maglev trains can make tighter turns than high-speed rails can. This allows guideways to be built which can navigate terrain much better (Wang 2010).
