...and even conventional trains seem to be too slow in comparison to planes. Now a new transportation mode has occurred that can clearly compete with planes in both speed and safety. They are called MAGLEV trains. The full form and the basic working principle of MAGLEV are called magnetic levitation. Many believe this mode of transportation holds great promise and offers considerable advantages. These trains use far less energy than other types of transportation and do not pollute. They can run at an average speed of 250mph that can climb much higher. The beauty of MAGLEV’S is that they travel on air. The consequent elimination of friction means much greater efficiency. Hence this gives an advantage over a regular train because there is no friction between wheels and the track. 2. WORKING PRINCIPLE The principle of magnetic levitation is that a vehicle can be suspended and propelled on a guidance track made with magnets. The vehicle on top of the track may be propelled with the help of a linear induction motor. Although the vehicle does not use steel rail they are still referred to as trains by definition they are along chain of vehicles which travel in the same direction. This is the definition of magnetic levitation (MAGLEV) train. As the frictional parts are minimum in this type of technology, the MAGLEV trains are known to have more...

...Magnetic Levitation Emerging Technologies By Nick Presson Introduction Magnetic levitation has been around for years, but with advances in technology it may become a part of everyday life. The main emphasis for magnetic levitation is for transportation. Magnetically levitated ground transportation, or “Maglev”, is an advanced mode of surface high speed transportation whereby a vehicle gliding above a guideway is suspended, guided, and propelled by magnetic forces. Can you imagine a train that that actually floats in air 4 to 6 inches in the air and travels up to 300 mph. This technology can reduce air and highway congestion, air pollution, and petroleum use. Traditional Systems The transportation system in the United States has been much admired around the world. Our extensive highway and air systems have facilitated business and leisure travel and contributed to a high quality of life for many Americans. In 1990, 429 million passengers traveled 342 billion passenger miles on commercial airlines. Americans traveled 2 trillion passenger miles my car, truck, bus, and public transit, and 6.1 billion passenger miles on Amtrak. As population have grown and shifted, however, the traditional systems have become stressed. Congestion on highways and at airports, especially since September 11, not only wastes time and fuel increases, but also constrains mobility to the extent that economic...

...How works a Maglev train? A brief review of magnets will help explain how maglev (magnetic levitation) trains work. Every magnet has a north pole and a south pole. Similar poles of two magnets repel each other; opposite poles attract each other. These principles govern the levitation of maglev trains. Permanent magnets are always magnetic. Electromagnets are magnetic only when an electric current flows through them. The north and south poles of an electromagnet are related to the direction of the current. If the direction of the current is reversed, the poles are reversed. In maglevs that levitate by magnetic repulsion, the train lies over the guideway. Magnets on top of the guideway are oriented to repel similar poles of magnets in the bottom of the maglev. This pushes the train upward into a hovering position. This system is designed for maglevs that contain groups of extremely powerful superconducting electromagnets. These magnets use less electricity than conventional electromagnets, but they must be cooled to very low temperatures—from −269 degrees Celsius to −196 degrees Celsius. In maglevs that levitate by magnetic attraction, the bottom of the train wraps around the guideway. Levitation magnets on the underside of the guideway are positioned to attract the opposite poles of magnets on the wraparound section of the maglev. This raises the train off the track. The magnets in the guideway attract the wraparound section only strongly enough to raise the train a few centimeters...

...ABSTRACT Maglev has been a long standing dream of railway engineers for the past century. These engineers envisioned a train that could float above its tracks. They saw the enormous potential for a train like this. The research on magnetic train which called maglev train was started in the beginning of the 1990 century. This concept lay dormant for about60 years. Then Japanese started their research on maglev train in the beginning of 1970 & constructed their first test line in 1997. German also started their research on maglev train in early 1970. It took them ten years to complete their first test line. The train works on the principle of electromagnetic effect. In this there is no friction between the train and track. The electromagnet on the underside of train pulls it up to the ferromagnetic stator on the track & levitates the train. The magnet on the side keeps the train from side to side. A computer changes the amount of current to keep the train 1 cm from the track. This means there is no friction between track & train. As it is high speed train compare to other types of train also noise level due to this train very less & energy consume is less, it is very convenient & beneficial to use. CHAPTER 1:-INTRODUCTION 1.1 History:- Magnetic levitation is the latest in transportation technology and has been the interest of many countries around the world. The idea has been around since 1904 when Robert Goddard, an American Rocket scientist, created a...

...A Paper Presentation On “Magnetic Levitation Trains” For [pic] ABSTRACT Imagine a train that doesn't touch its track and think of the potential for lower guide way maintenance costs as a result. Imagine a train that speeds along much faster than anything on the highway with a ride as smooth as silk. Imagine that train being capable of speeds higher than any other ground-based transportation system. Maglev can provide this speed and compete directly with airline travel. As stated by American Maglev, "Maglev means magnetically levitated and propelled vehicles. The advantage of maglev is that it can achieve very high speed and acceleration/deceleration performance because the vehicles essentially "fly" at very low altitudes - unlike trains or cars; there is no surface contact or "friction" to slow them down. More speed = more passengers." Only when we have real revenue-producing systems in operation will be able to prove whether this is true or not. In Maglev—which is short for MAGNETIC LEVITATION—high speed vehicles are lifted by magnetic repulsion, and propelled along an elevated guide way by powerful magnets attached to the vehicle. The vehicles do not physically contact the guide way, do not need engines, and do not burn fuel. Instead, they are magnetically propelled by electric power fed to coils located on the guide way. Indeed this is the beginning...

...INTRODUCTION MAGNETIC LEVITATION TRASPORT, OR MAGLEV, IS A FORM OF TRANSPORTATION THAT SUSPENDS, GUIDES AND PROPELS VEHICLES VIA ELECTROMAGNETIC FORCE Air flights are and will remain beyond the reach of a major section of society, particularly in India. Moreover there are problems of wastage of time in air traffic delays and 2 growing safety concerns. Trends in increased mobility of large masses with changing lifestyle for more comfort are leading to congestion on roads with automobiles. Besides, increasing pollution levels from automobiles, depleting fuel resources, critical dependence on the fuel import and due to a limited range of mobility of buses and cars the need for fast and reliable transportation is increasing throughout the world. High-speed rail has been the solution for many countries. Trains are fast, comfortable, and energy-efficient and magnetic levitation may be an even better solution.Development of magnetic levitated transport systems is under progress in developed countries and it is just a matter of time they make inroads to India as well. Therefore, it will be interesting to know about the science and technology behind mass ground transport system known as "magnetic flight". A LITTLE HISTORY In 1922 a German engineer named Hermann Kemper recorded his first ideas for an electromagnetic levitation train. He received a patent in 1934 and one year later demonstrated the first functioning...

...Essay Thesis: Maglev trains will be the future of transportation providing benefits for the environment, society, and economic benefits. In our world today we have many problems. Problems that we are facing are environmental, social, and economic issues. This is due to the fact that traveling to work has become a hassle and when your using your car it also causes environmental damage. When people travel in their cars they have to fill it up with gas, which we have seen, gas prices increasing tremendously. This causes social problems because people don’t want to travel because it’s too expensive. The environmental problems we have are the fact that CO2 emissions are polluting over environment and causing harm to everyone. The result of this is global warming which is affecting our environment and society. Economic issues are the fact that importing and exporting oil is expensive. This is why we need to find an alternative. That’s why Maglev trains will be the future of transportation providing benefits for the environment, society, and economic benefits. Maglev trains use electromagnets, which make the train levitate. This causes the train to cause no friction and “may be a travel solution of the future”. This means that it doesn’t cause any noise pollution, which is great for ecosystems living around the track and also benefits society because then they don’t have to here the noise of the train, which most people find annoying. Personally I live right by the GO station...

...scientist, created a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years, but it was not until the 1970’s that Japan and Germany showed interest in it and began researching and designing. The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields, the Maglev train can be levitated above its track, or guideway, and propelled forward. Wheels, contact with the track, and moving parts are eliminated on the Maglev train, allowing the Maglev train to essentially move on air without friction. [pic] FIGURE[1] BASIC PRINCIPLE OF MAGLEV TRAIN Maglev can be used for both low and high speed transportation. The low speed Maglev is used for short distance travel. Birmingham, England used this low speed transportation between the years of 1984 and 1995. However, engineers are more interested in creating the high-speed Maglev vehicles. The higher speed vehicle can travel at speeds of nearly 343mph or 552 km/h. Magnetic Levitation mainly uses two different types of suspension, which are Electromagnetic Suspension and Electrodynamic Suspension. However, a third suspension system (Intuctrack) has recently been developed and is in the research and design phase. These suspension systems are what keep the train levitated off the track. PROPULSION...

...Intrpduction : Maglev systems are becoming a popular application around the globe. Maglev trains are popular in transportation stations in big countries like Germany, China, Japan and the United States of America due to the demand for high-speed transportation, as the general public transportation services become more congested with increase of population. Maglev trains are magnetically levitated trains that traverse in a very high speed, with only electricity being its main source of energy. The train propels forward without any friction from moving mechanical parts. It has many advantages with minor drawbacks. The basis of maglev trains mechanisms are magnetic levitation. This is achieved with the principal of repulsion and attraction between two magnetic poles. When two magnets have the same poles, it will repel with each other and when it has different poles, the result would be otherwise. There are currently three known maglev suspension systems. In this project report, we will be covering the basic principals of Electrodynamic Suspension Systems (EDS), Electromagnetic Suspension Systems (EMS) and Inductrack. The three suspension systems each have different characteristics and special features. While EDS and EMS both use only the interaction of magnets and superconductors, Inductrack uses coils on the track underneath the train body. All three suspension systems work under the same principal of magnetic levitation covered in this project report. The maglev propulsion...

...Magnetic levitation (maglev) is a relatively new transportation technology in which noncontacting vehicles travel safely at speeds of 250 to 300 miles-per-hour or higher while suspended, guided, and propelled above a guideway by magnetic fields. The guideway is the physical structure along which maglev vehicles are levitated. Various guideway configurations, e.g., T-shaped, U-shaped, Y-shaped, and box-beam, made of steel, concrete, or aluminum, have been proposed. Figure 1 depicts the three primary functions basic to maglev technology: (1) levitation or suspension; (2) propulsion; and (3) guidance. In most current designs, magnetic forces are used to perform all three functions, although a nonmagnetic source of propulsion could be used. No consensus exists on an optimum design to perform each of the primary functions. Suspension Systems The two principal means of levitation are illustrated in Figures 2 and 3. Electromagnetic suspension (EMS) is an attractive force levitation system whereby electromagnets on the vehicle interact with and are attracted to ferromagnetic rails on the guideway. EMS was made practical by advances in electronic control systems that maintain the air gap between vehicle and guideway, thus preventing contact. Variations in payload weight, dynamic loads, and guideway irregularities are compensated for by changing the magnetic field in response to vehicle/guideway air gap measurements. Electrodynamic suspension (EDS) employs magnets on the moving vehicle...

In the November 1 issue of the Journal of Colloid and Interface Science, Ohio State University engineers describe how they recreated the texture, which resembles a carpet of tiny eggbeater-shaped fibers. In nature, air pockets trapped at the base of Salvinia's hairs reduce friction in the water and help the plant float, while a sticky region at the tips of the eggbeaters clings lightly to the water, providing stability. In tests, the coating performed just as the Salvinia hairs do, the bases of the hairs were hydrophobic, while the tips of the hairs were hydrophilic and so water droplets did not penetrate between the hairs, but instead clung to the tops of the eggbeater...

...The B&O Railroad By: Jaime Lewis For: Professor Knutson November 26, 2013 CON 101 Abstract The construction of the Baltimore and Ohio Railroad started in July of 1828. The city of Baltimore came up with the idea to build this railroad from Baltimore to Ohio because of the competition throughout the popular seaports in the United States. Baltimore was already a popular city, but adding a train that could carry people as well as goods would make more people travel to Baltimore, and other places along the train’s route, bring goods into Baltimore, and help keep Baltimore alive. The B&O railroad was always expanding. The railroad is best known for being the first railroad in the United States that used a steam locomotive. B&O Railroad Why was there a need for the Baltimore and Ohio Railroad? The Baltimore and Ohio Railroad was built due to competition throughout the main seaports in the United States. Due to the fact that Baltimore is at the top of the Chesapeake Bay, it had many advantages over other ports. Another way for goods to be transported from Baltimore all they way to Ohio was a great idea for Baltimore, therefore causing the plan for the B&O Railroad. During this time Baltimore was flooding with business. They constantly had ships coming into the harbor as well as trucks riding the highways. Baltimore was (and still is) such a popular and thriving city, so the railroad made sense to help keep business, and the city, alive. Baltimore had to...
