Germany To Build New Maglev Railway
EWAdams writes "According to the BBC, the Bavarian state government has announced that it has signed an agreement with Deutsche Bahn, the German state railway system, and the Transrapid consortium, to provide a maglev railway between central Munich and its airport. The only other maglev in full operation at the moment is in Shanghai, again as a city-to-airport service. The cost of the system is estimated at $2.6 billion. No completion date has been announced."
Actually for one of the companies involved in building the Maglev.
Copper theft is a problem mostly in open tracks but this one would be closed. The computer systems used can monitor intrusions onto closed tracks but only usually monitor intrusions in closed areas on open tracks like where PLCs are located (the controlers that work things like switches and interlockings etc). Also most new tracks are often made accessable only by maintenence trains rather than just being able to "walk" out onto the tracks.
In the cases of attempted copper theft on open tracks...I have some pretty gory stories that usually start with "what's that smell?"
Whilst the Shanghai maglev is indeed a great train ride experience, it does not actually terminate anywhere near "downtown" Shanghai. It terminates about 15 kms from the Lujiazui central business district and does not cross the Pudong river to the Puxi side (Huaihai Road or Nanjing Xi Lu) business districts.
The reality is that the Shanghai maglev is poorly used because it fails to deliver travelers to where they want to go. The Shanghai maglev would be a spectacular success if it actually terminated in one of the major business districts in Shanghai. But it does not.
As it stands, it is a white elephant. A trimuph of engineering and an amazing proof-of-concept - but a terrible piece of transport planning.
A dream is good. A plan is better.

Synergies are basically awesome, and they're even better when you leverage them. -PA
My impression from the article was that the merit of the chosen design was a passive train. Making the track passive instead would greatly increase the weight of the train and hence the energy cost of getting up to speed.

Informative? What a load of BS. Where exactly would you have the Maglev take you? To your hotel? You do realize that Shanghai is a huge city and that different people have different destinations, right? The Shanghai maglev takes you to the Long Yang Lu metro stop, and from there you can go anywhere you want, essentially, in the city.
Not to mention that the maglev costs 50 RMB and covers in 8 minutes a distance that a taxi costing 100 RMB would cover in 40. So especially if you're traveling alone, the maglev is by far the most convenient way to get in and out of Shanghai. If you're with your whole family and don't want to deal with public transportation, a taxi might be more convenient -- but it will most certainly be slower.
Why yes, I lived and worked in Shanghai for almost 3 years, thank for asking.
Insightful comment, and I agree with you. Maglev technology is really an answer in search of a question. Until high-temperature superconductors become economically feasible, power consumption, and the concomitant pollution from power production, remain prohibitive. Remember that many countries, including China, Germany, and the U.S.A., rely on coal for power generation, and the real cost of the ecological damage and pollution from mining and burning coal doesn't enter the minds of most.
The real question, it seems to me, is why don't they invest those billions in new drivetrain, suspension, and rail technology. The French have achieved wonders with the TGV at a fraction of the cost, by continual refinement of well-proven engineering technology. And they've been in operation throughout France and much of western Europe for more than 25 years, without a single fatality over a speed of 160 kph. The recent successful trials during which a modified TGV set a speed record of 574 kph (357 mph), should be an indication of what is possible. The train had such refinements as more powerful electric motors, lighter axles, larger wheels, and in-cab signaling (the driver doesn't have to rely on trackside signals), and ran a route chosen with long, straight segments, and without sharp curves.
Revolution is sexy and makes the headlines, but the steady progress of evolution is not to be sneezed at. Hell, the x86 processor architecture is still alive and kicking, long after its demise was predicted. I guess nobody told Intel's engineers that it was obsolete, or that further refinements were impossible. Maglev makes headlines with its promise of a Star Trek future today, but TGV's simply keep on hauling millions of passengers in safety and comfort every year. On runs of three hours or less they have largely replaced air travel. Such routine, dependable, reliability is a remarkable achievement.
