Nowhere in the world has Maglev been operated at such speed. The only Maglev currently operating is the Shanghai Maglev which runs on a stretch of just 30 km with a top speed of 431 kmph. It is more like a metro than a real train. It hasn’t been able to generate profit anytime. The commercial run started way back in 2004 but even after 13 years hasn’t expanded its network which shows that its not feasible to operate at such cost.

全世界没有一个地方的磁悬浮运行速度有如此之快。目前唯一运行的磁悬浮在上海，但它的运行范围只有30公里，最高时速为431公里。它更像是地铁而不是真正的火车。而且它在任何时候都无法盈利，商业运营早在2004年就开始了，但即使是在13年后，也没有扩大它的网络，这表明以这样的成本运营是不可行的。

In the last 20 years, has built a 22,000 km vast network high speed railway for the wheel based trains with Maxmum Speed of 400 kmph.

在过去的20年里，建成了一条22000公里的高铁网络，用于轮轨列车，最高时速为400公里。

It took $1.2 Billion to construct just a 30 km stretch for Maglev in 2004. Maglevs also have a much higher operational cost.

2004年，仅仅30公里的磁悬浮，他们就花费了12亿美元。而且磁悬浮的运营成本也要高得多。

Bullet trains are proven technology and many countries aspire to run them but you can’t say the same for Maglevs. So its better to invest in bullet trains rather than in Maglevs.

高铁是经过验证的技术，许多国家都渴望使用这种技术，但磁悬浮却与此不同，投资高铁比投磁悬浮要更好。

The Japanese have been able to run the wheel based 300 kmph bullet trains on a marginal profit.

日本人已经能够以300公里的时速运行轮轨高铁了，虽然利润很微薄。

To understand what is there in here, let me give u an example. Say u have a black and white mobile which is 15 years old and which is not performing well now. So the remedy is to take a new device. But u have a large array of options: feature phone, smart phone, non media colour phone, torch phone etc. An average smart phone costs around 6000 inr. And a feature phone around 3–4k inr. Had india invested on maglev train, it would be like you investing money on a high tech smartphone than on a feature phone first.

为了更好理解，我举个例子：假设你有一部已经用了15年的黑白手机，但现在性能不佳，所以补救方法就是买一款新手机，但是你有很多选择：功能手机，智能手机，非媒体彩色手机，触屏手机等等。普通的智能手机售价大约6000卢比。功能手机大约在3000-4000卢比左右。如果印度投资磁悬浮列车，就像你选择高科技智能手机一样，而不是首选功能手机。

Secondly india needs to know what wheel based HSR technology is b4 upgrading to maglev HSR technology.

其次，在升级为磁悬浮高铁技术之前，印度需要了解清楚基于轮毂的高铁技术是怎么一回事。

Manglev is under experimental stage and may never be economically viable(at least next 10 years) even for countries like Germany and Japan which developed them.

磁悬浮正处于试验阶段，即使是对德国和日本等开发磁悬浮的国家来说，也可能永远无法实现经济上的可行性(至少在未来10年)。

Considering the path breaking progress made by Elon Musk in develo PayPal and SpaceX , It may be feasible for him to economically implement the Hyperloop, capable of running at 1200+ km/hr

鉴于伊隆马斯克在开发PayPal和SpaceX上所取得的突破性进展，对他来说，实现能以1200+ km/h的时速运行的超级高铁在经济上可能是可行的

Maglev is still a develo technology. It's implementation is going to be costly. Since Indian industry is not develo this technology, all the money in implementation is going to go outside, why do it.

磁悬浮仍然是一种发展中的技术，而且造价昂贵。由于印度相关行业尚未开发这项技术，那么建设磁悬浮的所有花费都将流向国外，那干嘛要选磁悬浮呢?

Rail based HSR technology is stable technology. It'd be far cheaper than it was when it was develo.

基于轨道的高铁技术不仅稳定，而且和开发时的价格相比，高铁技术目前的造价便宜多了。

As Billu Mandal mentioned, Maglev is still yet-to-be-fully-developed technology where as bullet is already well established and proved to be safe.

正如比鲁•曼达尔(Billu Mandal)所提到的，磁悬浮技术发展还不成熟，然而高铁已经颇具规模并且经证实是安全的。

Cost also is another issue- maglev needs almost 50 times more money to construct per km than bullet.

此外，成本也是一个问题，磁悬浮每公里的造价几乎是高铁的50倍。

Its Maglev is too advanced for nation like India. It's Power drained and would require far outstanding engineering capabilities with social decipline. What would happen if people agitate on Maglev tracks or damage the tracks when a train is rushing at 500km h.

磁悬浮技术对于像印度这样的国家来说太先进了。它耗能巨大，需要非常出色的工程能力和社会纪律。如果民众对磁悬浮轨道不满，或者当列车以500公里的时速疾驰时损坏轨道，会发生什么后果?

Because maglev requires a motor as long as the travel distance consisting of copper wire and magnetisable poles

the HSR only requires 2 iron rails and some sleepers over the same distance

you will only see maglev on very short high value routes such as city centre to airport

因为磁悬浮需要一个能覆盖整个行程的发动机，由铜线和磁极组成。

高铁只需要2条铁轨和一些间距相同的枕木。

你只能在非常短的高价值路线上看到磁悬浮列车，比如市中心到机场

We didn't do so for these reasons: Will maglev be successful in India?

我们没有这么做是因为：请查看--磁悬浮在印度会成功吗?
