“Neither a wise man nor a brave man lies down on the tracks of history to wait for the train of the future to run over him,”- President Dwight D. Eisenhower. Maglev is a new type of train that uses magnets to levitate above the track and reduce friction. Maglev can go up to a speed of 310 mph (500 km/h) allowing people to travel on land much faster than before. The researcher will create a model Maglev and see which system, EMS or EDS, will result in better efficiency. Efficiency will be measured by the ratio of weight of train to the time to cross the track. If EMS weighs more but is faster while EDS weighs less but more to operate, than EMS should result in better efficiency because the train will weigh less.
How Maglev Works
Electromagnetic Suspension (EMS)
Electromagnets are magnets that can be turned on and off with electricity. There is a big power source, metal coils in the track and magnets under the carts. The Maglev does not have an engine but is propelled by magnets in the track, called a guideway. Magnets in the guideway, repel the magnets in the train causing it to levitate between 1 to 10 cm. The magnets in front of the train are turned to pull the train while the magnets behind the train push it. Since the train is levitating, the friction is taken away and can cause the train to go up to speeds up to 500 km/h (310 mph).
A German company called Transrapid uses Electrodynamic Suspension (EMS). The bottom of the train wraps around the track and levitating it at 1 cm. Transrapid has shown that this system can cause the train to go 300 mph with people on board.
Electrodynamic Suspension (EDS)
Japan uses a system called Electrodynamic Suspension (EDS). It uses super-cooled superconducting magnets that ar...

The strategy behind the high-speed railway system would be to relieve highway congestion, air traffic congestion, and help reduce the necessity of expansion of highways and air systems (which is limited due to the inability to build new air space). Also, with this type of system (this system works on magnetic levitation), you would have a significant reduction in air pollution that would result as high-speed captures a large portion of the intercity travel market from automobiles and airlines.
Electric traction had numerous advantages over steam railroads. One major advantage was electric locomotive’s ability to pull heavier loads than steam locomotives (Bezilla, 30-31). One statement from electrical manufacturers’ stated that an electric locomotive could pull from five times its own weight on a 2% grade, whereas a steam locomotive on the same grade could only pull two times its own weight (Bezilla, 31). In addition to this, the electric motors could sustain higher currents for a short time in order to increase horsepower dramatically; steam engines had no analogous feature (Bezilla, 31). These factors combined allowed for electric locomotives to accelerate more rapidly, even while pulling more weight, than steam locomotives (Bezilla, 31). The electric motor also had less moving parts and thus needed less maintenance than complex steam engines (Bezilla, 31). For example, the Pennsylvania Railroad’s electric locomotives in 1940 were typically running 90% of the time, but the steam locomotives that the electric ones replaced had only ran 69% of the time (Bezilla, 32). The...
“Ask not what your country can do for you, but what you can do for your country” John Fitzgerald Kennedy’s famous 1961 inaugural address began one of the most important presidencies in the history of the United States. The 35th president of the United States was like no other, he had a leadership quality that as the quote implies, gave the people empowerment, and held a relationship with the American people different than the prior 34 presidents.
This will run on electricity and is an electric superbike. This would not only be used for daily transport purpose but also for the recreation racings.

The world of Model Train Building has grown greatly with the aid of computers and technology to enhance the fun of building. Technology has long been a part of Model Train building with the adding of lights, bells, and whistles to capture your interest and imagination. But with the latest generation of building comes the influx of technology and the computer. The computer brings along a new breed of builders who plan track layout, buy parts on the Internet, receive updated news, and chat with other enthusiast.
No one person can be credited for the invention of the railroad; rather there are many individuals who contributed to the railways final design. To begin, as far back as the 16th century, Germans were using horse-drawn wagons, pulled along wooden rails. These systems were known as “wagonways” and are grandparents of modern railways. By 1776, wooden rails and wheels had been replaced by iron. Eventually, the wheels became flanged, allowing the wheels to better grip the rails. The major turning point of locomotives was the invention of the steam engine. The steam engine was invented by three different British inventors, over a period of a hundred years; to give only one man the credit would be a crime.

You apprehensively walk up the iron steps and onto the platform. You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart. But there’s no magic involved with these fantastic creations, there’s a plethora of forces and laws governing their every movement. From kinetic energy to inertia, roller coasters are intricate engineering marvels that function through the laws of physics. This is a look into those physics that result in a thrill ride unlike any other.
The earliest prototypes of self-powered vehicles began in the 1700’s with the first one being built by Nicholas Cugnot, weighing over 8000 pounds and clocking in at a top speed of 2 miles per hour (Bottorff). This large size and slow speed meant that it was impractical as an automobile. Several other prototype vehicles were built in this style by various inventors but were so heavy that they required metal rails to drive on, and so over time they evolved into trains and locomotives (Bottorff). Trains and steam power continued to develop and interest in a self-powered vehicle that didn’t require tracks faded, until the mid-1800’s when new developments in power sources encouraged the development of the automobile.
“A roller coaster is essentially a gravity-powered train (2).” Gravity is the weakest of the four physical forces, but when it comes to roller coasters, it is the dominant one. It is the driving force and what accelerates the train through all the turns and twists. Gravity is what applies a constant downward force on the cars. The deceleration or acceleration mostly depends on the inclination of the angle relative to the ground. The steeper the slope is, the greater the acceleration, and vice versa.
Furthermore, the high-speed rail network could mean twenty-nine million fewer car trips and 500,000 fewer plane flights annually, according to a 2006 study ...
Rail transportation is a transportation in which for movement of people and goods which from one location to another destination. Rail had been takes the important role in physical and economic development of town and cities in a country and it was developed over the world. Rail transport can be made a property value in a country increase and it must be needs improvement in transportation network expanding (Goldberg, 1970). Thus, the railway services need to be done with continuous improvement and it is important to the rail passengers of the range and quality of facilities and service on stations and trains (Gleave, S. D., 2000). The future development to a public transportation is a key to affect
A magnet has an invisible field that forces other objects to respond to its properties. This powerful force, which is referred to as the magnetic field, has particles called electrons that actively shift and move within the field. These electrons constantly revolve around the poles, thereby creating energy that attracts objects. Because of this, a magnet has the ability to draw objects towards itself. This ability, which is called magnetism, is caused by the force field that magnets create through its protons (positive charge) and electrons (negative charge).
