TRANSRAPID
STAYS ON TRACK DESPITE
SETBACK FOR SHANGHAI MAGLEV
According to The
Times newspaper in London, the Transrapid technology applied to the 30
km trial length of Shanghai’s maglev rail connection has become a
symbol of Germany’s economic decline as its builders were forced to
admit that it does not work. The newspaper reported that the opening of
the U.S. $1.2 billion rail link from the Metro to Pudong International
Airport has been delayed until next year because the train set that took
30 years to develop had repeatedly and inexplicably stopped.
No doubt it is
true that the Chinese Government is not impressed with this display of
German technical mastery, but ThyssenKrupp who are supplying the trains
and control equipment commented:
“Work on the
Transrapid order in Shanghai is progressing on schedule. The first
five-section vehicle started trials at the beginning of April and has
already reached the envisaged speed of 430 km/hour. The second parallel
track was released for start-up operation in May.
“Tests involving
two vehicles passing in opposite directions have also commenced. During
trial operations, a problem was identified with the cable winding of the
long-stator motor. In some cases, a combination of several unfavourable
factors resulted in damage to the cable sheathing. This in no way
detracted from the safety and functionality of the propulsion unit or
the system as a whole.
“Nonetheless, in
close consultation with the Chinese customer [Shanghai Maglev
Transportation Development Co. Ltd. whose President is CIOB China member
Wu Xiangming], we have decided to replace the cables. The timetable will
not be affected by these measures and commercial operation is still
planned to commence in early 2004. The customer SMTDC welcomes
ThyssenKrupp’s decision and is providing active assistance to rectify
this problem as quickly as possible.”
‘FLOATING
ABOVE THE MAGLEV GUIDEWAY’
The long-stator motor is the key to propulsion of the high speed maglev
trains. As Wu Xiangming explained, the synchronous long-stator linear
motor literally floats above the maglev guideway and is propelled
forward by powerful electro-magnetic forces. The guideway system has
been designed and built by Chinese engineers: it consists of 2,500 box
girder units each 24 m in length which yields 30 km of track in each
direction. Everything got off to a splendid start when at the end of
last year China’s Premier Zhu Rongji took the German Chancellor
Gerhardt Schroeder for a ride to the terminal at Pudong Airport and back
again to Longyang Road Station. On that day, fortunately for everyone,
the trainset behaved impeccably and reached the promised design speed of
430 km/hr within the stated eight minutes.
Wu Xiangming and
his engineering team were well aware from the outset that technical
problems were bound to arise in a piece of innovative technology which
is very much on trial. The schedule said that a three-section maglev
train-set must pass a test operation on a single track by January 2003,
which it did.
The test-run of
maglev trains on double track and turn around operations is due in
September, and in view of Thyssen Krupp’s confident assertion quoted
above, we may expect that to happen more or less on time.
The whole
installation is due to be completed and accepted by the client at the
end of the year but it now seems that the hand-over date will slip back
to January 2004. If all goes smoothly from now on, the Chinese
Government’s faith in German technology should be restored.
The Times asserted that on learning of the set-back caused by the linear
motor burn-out, the Government cancelled its plans for an 800-mile
Transrapid route between Beijing and Shanghai. But it seems doubtful
that any firm decision on such a huge project would be made at this
stage.
What seems more
likely is that the transportation situation in this economic powerhouse
region of China is being reviewed: the next step may well be a high
speed line between Shanghai and Hangzhou. The decision to go ahead with
the mighty Hangzhou Bay Bridge for motor traffic may be seen a pointer
in this direction, since development in this segment of the Chinese
economy would produce rich dividends in traffic paying its way, as well
as generating the financial resources to support such megaprojects.
