Why do actors in movies listening for a train put their ears close to the railroad tracks?
The way I understand it, they put their ear to the track to listen or feel the vibrations of the train coming, sort of like when a doctor uses a stethoscope to listen to your body. Allow me to add: A train track is a solid piece of metal sometimes as long as 1000 miles. a train can weigh 2-12 million pounds. this creates a lot of kinetic energy that will be felt many miles in both directions. it can also tell you if a train is coming closer or going away from you. This doesn't work with stagecoaches though.
What are the different types of maglev trains?
The three types of maglev trains are EDS (electrodynamic suspension), EMS (electromagnetic suspension) and stabilized permanent magnet suspension (SPM). * For EMS, same pole electromagnets in the train repel it away from a magnetically conductive track. * The EDS uses electromagnets on both the track and the train, to push the train away from the track. * SPM uses opposite arrays of permanent magnets to magnetically levitate the train above the track. http://trains.suite101.com/article.cfm/maglev_trains
