Transrapid Wallpapers

Transrapid train; photo wallpapers: Transrapid is a German monorail system using magnetic levitation. Based on a patent from 1934, planning of an actual Transrapid system started in 1969. The test facility for the system in Emsland, Germany was completed in 1987, and on 17 June 1993 the Transrapid TR-07 vehicle reached a record-breaking speed of 450 kilometers per hour. Today the maximum design speed has exceeded the 500 km/h (310 mph) mark and currently stands at about 550 km/h, with the fastest (and currently the only operational) scheduled passenger service reaching 430 km/h between Longyang Road station and Pudong International Airport in Shanghai, China. On 12 November 2003 the Transrapid in Shanghai obtained its own new record of 501 km/h as the fastest commercial magnetic cushion train (world record is now held by JR-Maglev with 581 km/h). The system is developed and marketed by Transrapid International, a joint venture of the German companies Siemens AG and ThyssenKrupp. The synchronous longstator linear motor of the Transrapid maglev system is used both for propulsion and braking. It functions like a rotating electric motor whose stator is cut open and stretched along under the guideway. Inside the motor windings, alternating current generates a magnetic traveling field which moves the vehicle without contact. The support magnets in the vehicle function as the excitation portion (rotor). The respective magnetic traveling field works in only one direction, and therefore makes moving train collisions less likely, as more than one train on the track section would travel in the same direction. The superspeed maglev system has no wheels, axles, transmissions, or pantographs. It does not roll; it hovers. Electronic systems guarantee that the clearance remains constant (nominally 10 mm). To hover, the Transrapid requires less power than its air conditioning equipment. The levitation system and all onboard electronics are supplied by the power recovered from harmonic oscillations of magnetic field of the track's linear stator (Those oscillations being parasitic cannot be used for propulsion anyway) at speeds above 80 km/h, while at lower speeds power is obtained through physical connections to the track. In case of power failure of the track's propulsion system Transrapid car uses on-board backup batteries that can supply power to the levitation system. At higher speeds (above ~200 km/h), the Transrapid is more energy efficient than a modern high speed train (ref), and considerably less noisy. It is capable of climbing significantly steeper tracks (10% vs. 4% for standard modern High-Speed Rail) and make tighter turns than conventional rail, rendering it especially suitable for mountainous regions. It is possible to flexibly adapt its guideway to the landscape and to have it tightly follow existing roads, railroad tracks, and power lines. Therefore, no significant interventions in the environment are necessary and pristine landscape is protected. Furthermore, the original use of the landscape under the guideway is still possible (farming or grazing for example).[br]
