What are 3 disadvantages for maglev trains?
Incompatibility with current trains
Vast requirement for copper wire.
Maglev trains have the technology to reach speeds in excess of 3,000 mph but any speed in excess of 300-400mph becomes impractical. The top speed depends more on how and where the maglev is built, how far apart stations are, and how much maintenance cost is considered acceptable. So, for the trains proposed so far today and may be in service in the next 20 years, it maglev trains will not exceed 400mph.
MagLev trains were first designed by a German man named Hermann Kemper. he was the first man to design and patent a MagLev train. The first MagLev train to be built and used was designed by Thyssen Henschel, another German, in the 1970's. The first passenger-carrying MagLev train was introduced in 1979 at the International Transportation Exposition in Hamburg, Germany. Thus began the MagLev train.
The Maglev train (also known as the Magnetic Levitation train) was invented in Germany, by a man named Alfred Zehden, in 1902. +++ The Linear Motor which is used to propel the levitated trains, was invented in Britain, in the 1960s I think, but sadly not developed here. in japan The technology in use for the Japanese MagLev was invented by two US inventors and was sold to the Japanese when no US investors could…
== == The very first trains were designed around 1825. Then in 1829 people were allowed to ride trains. Diesel and electric trains were invented somewhere around the 1950's. The maglev dates back to 1930. Trains were invented around 1825. People were allowed to ride the trains in 1829. Maglev trains date back to 1930. Diesel and electric trains were invented in the 1950's.
Cost, quite simply. As opposed to traditional trains where power comes from the pushcar of the train, a Maglev train doesnt propel itself, the track does. This means that expensive electromagnets with several electrical substations dotted along its path need to be constructed throughout the entire track's length. The initial cost of building these lines is too high for economically disadvantaged countries. The disadvantages of using the Maglev is that the Maglev tracks cost more…
This cannot be answered in the way it was asked. Maglev refers to magnetic levitation trains. This is limited to passenger trains. There are many systems in use on a maglev train system, not simply magnetic levitation - the magnetic levitation is in use in other systems, such as manufacturing, and has even been examined as a part of launching space vehicles, but is not referred to as "maglev".
Advantages : they'd be wonderful on the moon OR in vacuum tunnels bored through the Earth. Disadvantages : expensive, and by that I mean that their cost does not translate into savings. Like growing corn to make ethanol for fuel when the BTU's spent in fuel and fertilizer exceeds the BTU's you get from the alcohol.
