Maglev Train Concept…Is this for you?

Maglev train concept begins from the word magnetic levitation which means it is power driven and propelled by magnetic motors. In today’s transit needs, a sophisticated way of harnessing the magnetic force to achieve a vehicle floating in magnetic rails which allows the train to travel without any metal to metal contact underneath it. To make it work, 2 sets of magnetic force located in the train vehicle (permanent magnet) and the other magnetic linear motor located in the the magnetic frame rail.

Maglev train concept control:

Maglev train control is achieved by using computerized system that allows these 2 sets of magnets to interract with each other. Current is build up in the magnetic stator in the rails which then interact with the permanent magnet in the train vehicle using a continuous magnetic field. This interaction creates thrust which makes the train moves ahead. The same magnetic field is used for braking to stop the train vehicle. This magnetic control thus create a reliable acceleration and controlled braking in all kinds of weather. A frame is then use underneath to guide it magnetically which means there is metal contact between the vehicle and the magnetic rails.

Maglev train concept design principle:

there are propulsion coils on the guide way of the rail track frame used to exert a force on the magnets in the vehicle train and make the train move ahead. The propulsion coils that creates this magnetic force on the train are actually a linear motor: it is like having an alternating current flowing through the coils which generates a continuously varying magnetic field that moves forward along the track. The frequency of the alternating current is synchronized to match the speed of the train. The difference between the magnetic field exerted by opposing magnets in the vehicle train and the applied field create a magnetic force that propels the train to thrust forward.

Maglev train concept suspension:

One way to provide Maglev train to have stability is to use a set of coils along the bottom of the magnet array on the vehicle train, which allows it to center the vehicle in the magnetic field at all times. Since these magnetic coils are not needed to provide lift and there is almost no lift resistance, this system utilized almost no current especially when the vehicle is centered over the rails. As the vehicle train revolves around a curve, the vehicle main controller moves the vehicle to a “balance point” inside the curve so that the magnetic pull of the magnetic rails in the ground offset the vehicle’s moving kinetic force. This balance point is calculated based on the train’s weight and load which results in stabilized rate of power consumption. Overall, Maglev train consumed less energy when compared to steel wheels conventional trains.

The mag lift train experience, is this the future?

My mag lift train experience happened when I took a ride last night via U tube and I thought it was fantastic! The video was taken sometime in Nov 2005 and was done in Japan. From what I could sensed in the video, the ride was a little bit noisy although it was fast and efficient. Looking inside the maglift train, it was like having a plane ride except there is no climbing or taking off. All it is was a steady acceleration until the train reaches over 400 km per hour.

From this mag lift train experience, I could see the inside compartment looking similar to a plane where you have nice comfortable seats and stewardess seating everybody. I did not see any buckle straps which I assumed are not necessary since the train does not have any take off or excessive braking when the plane lands. Maybe, it should have but if any of you have actually have taken a mag lift train ride, please post it here in ATS. However, I did not see any “buckle up” signs either.

Here is the video that I saw taken from Japan:

To get a better mag lift train experience, I then saw another video taken which was shot just 1 year ago in Shanghai, China. This time, there was a bit difference: I could swear the ride was really quiet and includes showing a little boy talking and you can hear his voice clearly. This shows the train ride was really almost perfect because of absence of outside noise while the train was moving. Its like having a plane ride in first class comfort which is really safe and absolutely quiet.

Here is the video taken from Shanghai China:

To me, this kind of transportation is long overdue here in North America where almost everybody invest in expensive privately owned vehicles which harms our environment and basically divides us. At this time of hard economic times, public transport like mag lift trains should be installed so people will not only save precious energy but learn to live together and get along.

Mag lift train experience is something I would like to have in the future because it is fast as an airplane but a lot cheaper to travel without causing green house pollution.

Cheap Public Train Means Bullet Trains!

Cheap public train is handy during recession and declining economy, it is not actually surprising why people are using this transportation systems instead of using their own vehicles. As a matter of fact, many people are disgusted with the world economic uncertainty that they are now starting to sell their vehicles in favor of bikes and public transportation.

Cheap public train is a better choice if you want to travel quickly from one placeto another. This holds true especially if the destination you plan on going is very far away. The reality that air travel is getting more and more clogged up and plane tickets are also getting increasingly costly, trains are what people are now considering as an alternative way of traveling from one location to another. It is inexpensive, quicker than public buses and cars, and trains today are very dependable that it seldom breaks down.

Since more and more people are now taking the cheap public train as a way to commute, lots of countries are now having a look at bullet trains and are now starting to fund researches and explorations for new breeds of trains that is capable to go quicker, that is more dependable and can offer inexpensive transportation and bullet train seems to be the answer.

Bullet train is widely popular in countries like China and Japan including France that are using this type of trains outfitted with the most advanced engineering technology like the Maglev trains. Maglev is a term which represents magnetic levitation. This new type of train essentially has the same concept like the conventional train: it consists of tracks in addition to cars that accommodate passengers but in this Maglev system, the cars won’t be contacting the tracks. As a matter of fact, the train cars won’t have any wheels or moving parts. The principal theory of Maglev is to use magnetic polarization to raise the cars off the tracks and thrust them onwards. The same theory is also utilized for deceleration or stopping the train.

Because there will be no friction between the tracks and the cars, bullet train like this go at a much faster speed. In fact, it can reach over 450 km an hour without any problem. Try to imagine riding one from New York to Chicago? Though it won’t be as quick as the airplanes, you will arrive at your destination at a very fast rate. And since it has no friction or moving parts, you will have a smooth ride. And since it does not consume gas, this means no greenhouse effects. In the end, this is actually a cheap public train that not only save you a lot of money on gas, but also prevent polluting our environment.

In the long run, a cheap public train like this will let you enjoy the great scenery whenever you travel by train. Maglev bullet trains are definitely the train of the future. With the rate of development of this Maglev technology, soon or later, we it will have a cheap public train that can actually travel quicker than an airplane! As a matter of fact, this bullet train has the potential to reach the speed of sound.

Finally, if you ever see Maglev bullet trains traveling from one city to another, don’t be surprised if people prefer this as their cheap public train. This means the ability to travel to any destinations because it the best economical way of public transportation. And when this happens, this will be the death of private transportation but to the benefit of the most people around the world.
