What are the biggest disadvantages of maglev trains?

There are several disadvantages to maglev trains: - Maglev guide paths are more costly than conventional steel railway tracks. Because the magnetic coils and material used in this setup are very costly. - Maglev trains require an all-new set up right from the scratch.

Drawbacks of Maglev This involves a very high initial investment (Coates, 2004). Even though guideways cost less than rails over time (Powell, 2003), it is hard to justify spending so much upfront. Another problem is that maglev trains travel fast, but they might not travel quite fast enough.

Maglev trains do not create direct pollution emissions and are always quieter in comparison to traditional systems when operating at the same speeds.

Maglev trains are “driven” by the powered guideway. Any two trains traveling the same route cannot catch up and crash into one another because they're all being powered to move at the same speed. Similarly, traditional train derailments that occur because of cornering too quickly can't happen with Maglev.

Disadvantages of Maglev Trains Complications resulting in accidents will usually lead to high human fatalities. Maglev trains are much more expensive to construct than conventional trains because of the high number of superconducting electromagnets and permanent magnets required, which are usually very costly.

On 22 September 2006, a Transrapid magnetic levitation (or maglev) train collided with a maintenance vehicle near Lathen, Germany, killing 23 people. It was the first fatal accident involving a maglev train.

This reaction between the magnets creates a magnetic field. The field lifts the train off of the track. This lets air flow between the train and the guideway. The trains never touch the track; they hover just above the track.

Compared to highspeed passenger rail, maglev passenger rail consumes roughly twice the power per passenger kilometer. For commercial freight I found an efficiency figure of 520 ton-miles per gallon (660 kg-km/MJ). Assuming 70kg for the average commuter passenger this gives us an efficiency of (116 kg-km/MJ) for maglev.

The construction of the SCMAGLEV alone is set to create 205,000 jobs nationwide. Factoring in additional growth in supporting industries and businesses, increased tax revenue to local municipalities, effects on tourism, and access to more of the region in less time, the economic benefits will be monumental!

MORE DETAILS

Maglev trains have some advantages over traditional trains. As the train does not touch the ground along the guide road, it does not have any moving parts, so there is no part to wear. For this reason, the maintenance cost is low. Since there is no contact with the guide track, there is no friction.

Hermann Kemper (* April 5, 1892 Nortrup, Germany, in the district of Osnabrueck, † July 13, 1977) was a German engineer and is considered by many the inventor of the basic maglev concept. In 1922, Hermann Kemper began his research about magnetic levitation.

relying purely on magnetic forces However, this new 'Sky Train' system takes electricity out of the equation, using only magnets composed of rare-earth metals that 'create a constant repelling force [which] can lift a train with 88 passengers and keep it floating even without power,' states South China Morning Post.

If guideway power is lost on the move, the Transrapid is still able to generate levitation down to 10 kilometres per hour (6.2 mph) speed, using the power from onboard batteries.

As noted above the Maglev trains are capable of traveling at speeds nearly twice as fast as the bullet trains. However, the use of such extreme speeds in commercial travel seems unlikely. Whereas Maglev trains travel at speeds of up to 400 or 600kph, bullet trains travel at a modest 320kph.

As for the fastest speeds ever reached by a train, the honour of fastest train in the world goes to the L0 Series SCMaglev in Japan. On its test track this Japanese maglev train reached a top speed of 603 km/h or 375 mph. That incredible achievement means it can travel at almost double regular shinkansen speeds.

Maglev trains are even faster than Japan's famous bullet trains, which currently travel at about 200 mph (320 kmh). They will eventually consist of 16 carriages, carrying up to 1,000 passengers at a time and cutting the current travel time by more than half, from 90 to 40 minutes.
