Last week, it has been
announced by Japan Railways' Operator JR that Maglev, the train which works
with the technology of magnetic elevation, has reached 603 km/hr, according to
the test results conducted. This exceeds the previous record of 590 km/h. The
levitation technology is based on the principle of magnetic repulsion between
the track and the cars. The Central Japan Railway Company (JR Central) and the
company's Railway Technical Research Institute developed the system since many
years. In Europe, some doubts subsist in the railway industry. It is hard to
say how effective this technology will be optimal outside specific cases, say
some engineers. The expected target by Japan about the Maglev would change this
idea.
The name maglev is derived
from MAGnetic LEVitation. Magnetic levitation is a highly advanced technology, and
which relates to many industrial applications. The common point in all
applications is the lack of contact and therefore a universe without wear nor
friction. This increases efficiency, reduces maintenance costs, and increases
the useful life of the system. The magnetic levitation technology can be used
as an efficient technology in the various industries, including railways.
In Germany
The German maglev company
named Transrapid, had a test track in Emsland with a length of 31.5 kilometres.
The single-track line ran between Dörpen and Lathen with turning loops at each
end. The trains regularly ran at up to 420 kilometres per hour. Passengers were
carried as part of the testing process. The construction of the test facility
began in 1979 and finished in 1984. In 2006, the Lathen maglev train accident
occurred killing 23 people, found to have been caused by human error in
implementing safety checks after what no passengers were carried. At the end of
2011 the operation licence expired and was not renewed, and in early 2012
demolition permission was given for its facilities, including the track and
factory. No other test tracks are expected in Europe in the coming years.
In China
We can find the first real
Maglev in commercial operation in Asia, especially in China. Shanghai Maglev
Train (SMT) operats between Shanghai Pudong International Airport and Longyang
Road Metro Station. With the technological cooperation from Germany, the
world's first commercial magnetic levitation line was operated on Apr 1, 2003,
the designed maximum operating speed of 430 km/h is near the flight speed, and
the actual operating speed is about 300 km/h, the whole 30 km trip takes only
eight minutes.
In Japan
Working on the creation of
a train on a magnetic cushion began in Japan in the 70-ies of the last century,
however, these technologies for a long time no use. Construction of the
Yamanashi maglev test line began in 1990. The 18.4 km of the line in Tsuru,
Yamanashi, opened in 1997. MLX01 trains were tested there from 1997 to fall
2011, when the facility was closed to extend the line to 42.8 km and to upgrade
it to commercial specifications.
In 2011 the Japanese
government approved a plan for the construction of the first commercial line of
such trains with a length of 286 km between Tokyo and Nagoya. The project cost
is estimated at 5.5 trillion yen (€42,79 billion). The construction will
involve about 15.000 people. By 2045 this branch is planned to be extended to
the third largest city of Japan – Osaka. The average speed on the section
between Tokyo and Nagoya can be about 500 km per hour, which will allow you to
make the journey in 40 minutes. The duration of this same trip on high-speed
trains Shinkansen is now one hour and
18 minutes.
The Japanese public is
determined to realize this project. Yoshitsugu Hayashi, a railway professor at
Nagoya University says: “This is a good
example of Japanese technology and know-how, and it is important that Japan
remains ahead in the technology of magnetic levitation". That sounds
as a clear warning to all the railway industry...
