Electricity and the use of a super-conductor magnet system provides both lift (levitation) and provides the power and thrust for forward motion, which is also used in the braking systems. Hence the word, maglev (magnetic levitation)
No. Just resting skids for when there is no (electrical) power.
Depends. maglev trains run in electricity, and electricity can come from all sorts of sources. You can get it from hydro Power, nuclear Power, fossil fuels, solar Power etc. Renewable or not doesn't matter to a maglev train. They can run on anything that can be turned into electricity.
They "float" ... but not like a balloon. It takes power to hold them up.
Maglev trains do not use gas, so they are good for the environment.
maglev trains will appear very soon in NCR regions
Magnetic Levitation (MagLev) trains, hard disk drives for computers, vacuum cleaners, and several others
Yes.
They get on from an opening passage way that comes out of the maglev train
# It is a Magnetic Levatation train.

Maglev trains are faster than normal trains because they use magnetic levitation to reduce friction between the train and the tracks, allowing them to reach higher speeds. Additionally, maglev trains do not have wheels, which eliminates the rolling resistance experienced by traditional trains on tracks.
