High speed trains

English inventor Richard introduced the steam locomotive on 21 1804 in Wales, it achieved a of 8 km/h (5 mph). In 1815, George Stephenson built the first workable steam commissioned by the Killingworth colliery. In he introduced the first passenger which steamed along at 25 (16 mph). Today, trains can fly the tracks at 500 km/h (311 And fly they do, not touching the tracks.

for rail speed: Rail at 500 km/h (311 mph)

The for rail speed escalated Japan introduced the shinkansen Train on 1 October 1964 to Asia’s first Olympic held in Tokyo. The Bullet proved that there is not fascination, but also a market for trains.

In the early 70s, the built the TGV (Train Grande The TGV is the French version of high trains. There are many more than 350, in The German ICE3, built by reaches 330 km/h (206 The Eurostar comfortably hurls 700 along at 300 km/h (188 with its two motors pushing out kW. Siemens and French Alstrom up for the Spanish Talgo, which shrink distances at 350 km/h mph). In Australia, the Speedrail TGV run the Sydney-Canberra line at up to 360 km/h in 2004. In the US, the Acela will fly the tracks at 320 km/h (200 Even China is planning a new speed rail to quickly the 1,280 km (800 miles) Beijing and Shanghai. High trains also run in Britain, Belgium, the Netherlands, Switzerland, and South Korea. But perhaps is best known for its superfast holding the speed at 552 km/h mph).

TGV Atlantique, seats 485 at more 300 km/h (188 mph).

In it reached 515 km/h (321,8

The technology

To achieve amazing the magnificent powertrains called for new in track design. TGV tracks, rails on hybrid steel and ties, lay on a thick bed of ballast. The of curve radii and superelevation high speed possible: a 5 km (3 radius would be considered Instead of each car with its own they are semi-permanently attached on a truck between them.

The Maglev is a system in which the runs levitated from the by using electromagnetic forces superconducting magnets on board the and coils on the ground. When the pass at high speed, an current is induced within the which then act as electromagnets As a result, there are forces push the superconducting magnet and ones which pull upwards simultaneously, thereby the Maglev. The repulsive force and the force induced between the propel the Maglev forward at speed.

Fabulous flying

The actually does not touch the when traveling. Its superconductors let the float above the rails. The train levitate 1cm (0,39 in) the track. Japan’s shinkansen 10 cm (3,9 in) above the tracks. The uses wheels to reach 100 (62 mph) before it levitates. At supercold liquefied helium energy loss in the magnetic The European model uses magnets, but enables immediate

Maglev research started in and by 1970 studies of electrodynamic systems using superconducting took shape. The first run took place in 1979. In 1986, a 3-car train 352.4 km/h (220 In December 1997, a manned attained 531 km/h (331 and unmanned, attained 550 km/h mph). The following year, a of two trains passing each at a relative speed of 966 km/h was run In March 1999, an unmanned MLX01 reached 548 km/h mph). In April, the manned MLX01 set a fabulously fast speed record at 552 km/h mph).

The Eurostar uses its kW power to move 766 passengers at 300 km/h (188 mph)

How it stop?

TGVs have brakes, with brake for emergency stops. Trailers are with four disks per and backup brake shoes. induction track brakes are for the next models. Maglevs are down in the same way it is propelled, by magnets.

High speed are completely fenced off, and the maintained in top condition. Although have been derailments, in the two decades of daily operation, has been no casualties.

At high speed, it is impossible to lineside signals. All signaling is transmitted to the train through the directly to onboard monitors in the Most of the high speed functions are controlled digitally, to being the vehicle of the digital

the track

In 1815, George steam locomotive ran on tracks (4ft 8in) wide rails. Later he added (half inch) to the width of the It was to become the standard gauge or 4ft 8 1/2 in).

In December 1830, the Friend of Charleston, hauled a of cars on the tracks of the South Railroad, introducing the railroad to The first American-built locomotive was the Tom constructed by Peter Cooper.

In Frank J. Sprague completed the electric street railway. It ran (12 miles) in Richmond, Virginia. the first electric locomotives introduced only in 1895.

Diesel trains first in 1925. The world’s fastest train is the Russian TEP80, at 273 (147 mph).

The French TGV powered by a gas turbine, reached a top of 318 km/h (198 mph) on 8 1972.

The TGV Atlantique reached 515 (321,8 mph) on 18 May 1990. In it clocked 581 km/h ((363

In April 1999, a 5-car Maglev set a world record of 552 (345 mph).

The term is used only when the unit can be uncoupled from the

ULTra advanced public system

Always wanted own chauffeur? The bus or train driver not fitting the idea? Then you an electronic chauffeur. The Ultra might just do.

Ultra is an on system of driverless automatic traveling on their own guideway Developed at the University of Bristol, UK, it is by Advanced Transport Systems Ltd to with cities throughout the to provide effective and sustainable

An Ultra guideway has the same as a motorway lane (1800 per hour) but whereas the average in city centers are 13 km/h (8 the Ultra speed is 40 km/h, times faster. Typical times for even the better bus are 6 minutes. 80% of Ultra passengers have no waiting time 95% of all Ultra passengers will less than 1 minute, at peak times.

The Ultra much less energy per km than buses, cars, or light rail and is environmentally —

zero city The Ultra also travels to the destination, transporting 4 passengers in
