Worlds fastest Train :

                               JR-Maglev is a magnetic levitation train system developed by the Central Japan Railway Company and Railway Technical Research Institute (association of Japan Railways Group). JR-Maglev MLX01 (X means experimental) is one of the latest designs of a series of Maglev trains in development in Japan since the 1970s. It is composed of a maximum five cars to run on the YamanashiMaglev Test Line. On December 2, 2003, a three-car train reached a maximMagnetic levitation trains make use of a levitation system, a guide system, and a driving system.


Levitation

The JR-Maglev levitation train uses an Electro-dynamic Suspension (EDS) system. Moving magnetic fields create a reactive force in a conductor because of the magnetic field induction effect. This force holds up the train. The maglev-trains have superconducting magnetic coils, and the guide ways contain levitation coils.
When the trains run at high speed, levitation coils on the guide way produce reactive forces in response to the approach of the superconducting magnetic coils onboard the trains.
EDS has the advantage of larger gaps than EMS, but EDS needs support wheels which are employed in low speed running, because EDS can't produce a large levitation force at low(er) speeds (150 km/h or less in JR-Maglev). However, once the train reaches a certain speed, the wheels will actually retract so that the train is floating. JR-Magle floats 10 centimeters (approx. 3.9 inch) above the guideway.


Guide

Levitation coils which are located on the guide way generate guiding and stabilizing forces also.


Driving

JR-Maglev is driven by a Linear Synchronous Motor (LSM) System. This system is needed to supply power to the coils at the guide way.um speed of 581 km/h (361 mph) (world speed record for railed vehicles) in a manned vehicle run.


Yamanashi Experiment Lines are facilities that currently have a practical use. It includes about 18.4 km of track (including 16.0 km of tunnels). The test track is currently being extended from 18.4 km to 42.8 km with completion expected for 2013/14.

World's Fastest Plane : Son Of Concorde




Dubbed the "son of Concorde", the jet will revolutionize air travel if it ever takes flight. The large, windowless vehicle looks more like a missile than a passenger plane -- and moves more like one too. The aircraft will reach a top speed of Mach 5 (Go Speed Racer!), twice as fast as the now-retired Concorde supersonic airliner, and can fly from London to Sydney, Australia in under 5 hours -- less than quarter of current flight times. Even better, the engines will run on liquid hydrogen, meaning the only exhaust will be water vapor and nitrous oxide, so the carbon footprint of the jet will be negligible.
5 times faster than the speed of sound

The team of British engineers in the project LAPCAT supported by the European Space Agency (European Space Agency), took on the development of cleaner and supersonic passenger aircraft, code-named A2, which can speed 5 times faster than the speed of sound.

The aircraft will perform flights between Europe and Australia in less than five hours, reported AFP. For example, the duration of the flight from Belgium to Australia will be 4 hours 40 minutes.

Length A2 future aircraft will be 143 meters and the capacity - up to 300 passengers. Maximum speed of liner 6400 kilometers per hour, which is five times faster than the speed of sound.

For comparison, the length of the popular passenger aircraft Boeing-737 total 36.5 meters and the length of the largest to date A380 aircraft - 73 meters that about half of future aircraft.

It should also be noted that the A2 will fly on liquid hydrogen, which is more environmentally safe compared to the currently used fuels. Without refueling supersonic airliner will be able to fly up to 20 thousand kilometers, its creators claim.

The cost of a ticket to such a supersonic aircraft will be about £ 3500 (or almost USD 7000).
