JOSEPH RENNERHello. My name is Joe and this is my first forum. I have a few questions regarding mag Levs. Someone told me there is extensive mag-lev network in Beijing china. Could anyone please give me specifics on it? Also, I would love to hear your opinions on whether or not it could take off in America. Any information would be greatly appreciated. Thanks, Joe Renner
there are no extensive networks of maglevs anywhere. In fact many of the smaller installations have been removed. The only revenue service large scale monorail is the Shanghi airport line. JR East has committed to build a Tokyo Osaka line sometime in the future.
A few years ago there was a story in TRAINS about the trains in China. I kinda remember that the author rode the maglev and said the ride was rough, which surprised me since I always get the impression that a smooth ride is an advantage touted by those promoting maglev.

I'd suggest that mag-lev trains are probably a little too futuristic and too costly to do what they do well. It's kind of like the space shuttles. They were cool, cutting edge technology that got people excited about space again. However, there was a contingent of scientists who felt that the work of the space shuttles could have been done just as well by a bunch of "big, dumb, rockets" for a fraction of the cost. Mag-lev trains might be the answer, but we don't exactly know what the question is.
Thanks to Chris / CopCarSS for my avatar.

I rode the Shanghai demonstration maglev. Very smooth. The costs are too high and it has enviromental problems. Consequently, China cancelled the proposed section from Shanghai to Hangzhou, which was part of a line to stretch to Beijing. Conventional HSR was built instead to both Hangzhou and Beijing and is running very sucessfully.

I don't think Mag Lev will happen now.
The Japanese test track keeps being publicised, but it is suggested as the successor to the present Shinkansen owing to capacity constraints.
Adding two more Shinkansen tracks, maybe on an improved alignment, is a better solution. The trains can already run at speeds only slightly less than the Mag Lev at a fraction of the cost. Need more capacity - add more of the trains that have worked for many years.
The best chance of success was in China, and even there where billions were being invested, it cost too much for the capacity delivered.
Look at photos of the switches in Shanghai.... huge flexible beams in place of simple turnouts. It is never going to be cost effective.
It will be like the monorail in Seattle that it resembles in appearance - an alternative way of doing things that never caught on.

So far, mag-lev has been used in high-speed passenger applications. I think we can all agree that mag-lev for freight will never get off the ground. Literally.

i'm not so sure about that. JRCentral is quite focused on Maglev for the next line to Osaka and has received permission to move forward.

If the Maglev speed record becomes a sustainable speed, it would represent a considerable reduction in travel time compared to the current Shinkansens.
IMHO it will not be practical in our lifetime for cost, energy consumption and reliabilty reasons. It works as long as you get to play with an unlimited supply of OPM, but the real world doesn't work in a vacuum and those real world caused glitches will be intolerable to most.
Mag-Lev has been the future for many years now... and that future as gone nowhere. I love reading all my old Populr Mechanics, Popular Science, Mechanics Illustrated, ect magazines from the 70s- early 90s. There was always an article every few months on new mag-lev trains and other transporations technoligies that, as we know now, just never caught on. As most have stated money has been the big issue. Either there has a lack of money to continute development or the money has run out to continue opperation. Back in 1999 Old Dominion University partnered with American Maglev Technogies to build a mag-lev system on the campus. By 2011 14 million had be spent and the project had not gone far. Durring some of their first test runs on the compleated section their technolgy failed and the car can to a stop on top of the rail causing some extensive damage to the system. Since that time the partnership has been dissolved and the project had not gone far. There have been a few test runs that were successful but with glitches. Back in 2010 parts of the rail system that had never been used were scrapped so ODU could reinvest the moeny into their mag-lev train but little has been done since that time. And so this system sits idle needing money for repairs & continued research and for some and eye sore (or black eye) for the campus.
TG3 LOOK ! LISTEN ! LIVE ! Remember the 3.
Recently a nearly $28M grant was awarded for a study of Mag-Lev for the Baltimore-Washington corridor.

Never too old to have a happy childhood!
Wouldn't it make more sense (and save dollars and cents) to let the Japanese develop the technology then reverse engineer it?
Norm
Yes Federally funded maglev development, definitely including Balt. Wash., is one big waste of taxpayer funds, in my opinion.
Please explain what funding do you think would not be a big waste of taxpayer funds? You replied "yes" to Norm's suggestion for the United States to let the Japanese develop it, but do you think he's suggesting that the Japanese are going to use only private investors' money? I bet their government is the most likely funder. Regardless of what foreign entity invests in it, wouldn't they rightly expect to get paid something if anyone else uses proprietary technology that comes out of their investment?

No matter the O-D pairs - for any transportation medium the biggest obstical is getting a route. Mag-Lev currently has no route between any O-D pair, securing the real estate in established areas will most likely exceed the cost of elementary construction and could exceed the cost of construction as well as equipment acquisition. Then you will also have the 'asthetic NIMBYS' who do not want the vista of a Mag-Lev structure to spoil their view of the world. Then we come to supplying the electrical power demand for Mag-Lev - power is not free and in major metro areas additional power generation capacity will most likely have to be constructed.
Mag-Lev will require as much, if not more right of way than do existing rail lines.

Um, have you not been watching the Chineese modus operandi?
Um, I assume you mean that the Chinese government is investing in developing technology and expect to be able to get some return on that investment when they are able to export it and get paid?
Um, is there something wrong with it?

Reverse engineering is not as easy as it would seem. Some years back, "Air and Space: Smithsonian" had an interesting article about the effort involved by the Russians in reverse-engineering the B-29 into the Tu-4.
Reverse engineering someone else's work might not be what you'd consider ethical either.
And doing it on the scale needed for maglev [edited] probably is easlily discoverable and contrary to many trade agreements.
[the edit was I meant to say "probably is" instead of "might not be"]
Mind you, I'm not arguing one way or another about if it's worthwhile for anyone to invest in maglev, just about the appropriateness for a government to invest in its reasearch and their justifiable legal ability to get compensated if someone tries to use the research's results.
I get the impression that Mag-Lev proponents want 'their' system to be too complex to be 'corrupted' by freight operations.
Mag-Lev people look a present day US railroads and believe they have been ruined by their emphasis on freight transportation and the need for private enterprise to turn a profit on their investment in plant and equipment. Mag-Lev will be 'pure' and not have to rely on evil private money but will be glorious when operated with 'good' public money (tax monies extracted from every person, living or dead).
I'm not altogether sure which maglev people you're quoting, but the arguments I've seen all involve strictly economic concerns in the other direction -- that the large capital investment in land and infrastructure and subsequent careful maintenance to allow high running speeds don't come anywhere close to being justified by any level of additional freight revenue. If the Super C, running with existing cars and power over an existing railroad, couldn't justify its higher fuel costs, why would anyone expect that a dedicated lane with required intermodal transshipment at any point, and restrictions on consist composition, would do any better?
About the best that you'd get would be some amplification of M&E carried on passenger maglev trains. I note that the French ran dedicated trains of this type on the LGV early on ... but I don't think these are still run, even the dedicated postal stuff.
FedEx and other express services would probably use it for some of the traffic between points, since even FedEx express overnight uses trucks for many short-haul lanes (anywhere the overhead of accessing an airport and then going to the central Memphis facility and back would require greater time or uncertainty), and there should be adequate volume in some of those lanes (Washington-New York being one) to justify incorporating M&E of some kind in a maglev 'second spine' or whatever. But outside that, both the capital and maintenance costs would eat any reasonable profit motive alive. And freight railroads are responsible to their stockholders to justify where scarce development and maintenance money will be spent.
Mag-levs suffer from the same problem as monorails, switches (points in the UK) are very bulky and particularly difficult in a system where the 'rail' needs to be a continuous conducting surface. This is why all the implementations of these systems have been either a single loop (sightseeing lines, such as Seattle and Sydney, or airport shuttles) or a simple point-to-point (like the Shanghai mag-lev). There are (AFAIK) no complex networks based on monorails.
I've always liked the fact that, as 'buslist' alluded to above, the first commercial mag-lev system in the world...was replaced by cable-cars.Birmingham Maglev/AirRail Link. So in this case, I guess "Cable Cars: The future of railroading?"

Other concerns, including NIMBYs led to the Shanghai-Hangzhou line's cancellation. A good HSR runs today instead.
(Wiki) "Media reports on 26 May 2007 said the Shanghai city government announced that the project had been suspended, citing "radiation concerns", despite an environmental assessment by the Shanghai Academy of Environmental Sciences saying the line was safe and that it would not affect air and water quality, and noise pollution could be controlled. An environmental assessment report released 2 January 2008, for citizens to comment on until 15 January, says the link would have minimal impact on the local environment. In January and February 2008, hundreds of residents demonstrated in downtown Shanghai against the line being built close to their homes. The residents were reportedly concerned with potential health hazards, noise, and loss of property value. The Shanghai scheme has a buffer zone around the track that will be 22.5 m wide, which compares unfavourably with German standards that require houses to be 300 m away from the line. Representatives of the residents filed a formal request to demonstrate with the Shanghai Public Security Bureau, which was rejected. In October 2010 an HSR was opened that brought the travelling time between the two cities down to 45 minutes. An official revealed that the Maglev link was to be shelved."

A newer, experimental technology.
The Washington-Baltimore mag-lev makes absolutely no sense. Perhaps there are other places that could serve as cost-effective proofs of concept, but (as a Maryland resident) I see no compelling need for travel between Baltimore and Washington that isn't already served by MARC, Amtrak and commuter bus. My suspicion is that the enthusiasm for mag-lev is a shiny object to distract from discussion of feasible but costly improvements needed for Maryland commuting. Why improve or expand existing infrastructure (to include the NEC and DC's Metro) when we're "investing" on mag-lev?
