A monorail is a rail-based system that utilizes magnetic levitation
(maglev) to move a train on a single track (hence, MONO-rail). By
utilizing the power of magnetic levitation, monorail systems allow a
fast, smooth and quiet mode of transportation. One of the only
components that slows down this system is the drag produced from
air. There are a few different types of monorails that are used
today, one type runs above the rail and the other runs below the
rail. Monorails are efficient due to the utilization of magnetic
fields. Below are pictures and diagrams that show the components of
monorails and what makes them work.
