In the next 30 years, will all Indian trains become Maglev trains?

未来30年，印度火车都会更换为磁悬浮列车吗？

Currently there is only one commercially operating Maglev in the world i.e. the Shanghai Maglev in which runs over a distance of only 30km with a top speed of 431 kmph.

目前，世界上只有一条商业运营的磁悬浮，也就是上海的磁悬浮，全长只有30公里，最高时速431公里。

Japan is currently testing Maglev which reached a top speed of 603 kmph during test runs. The operational speed will be around 500 kmph and the service will be between Tokyo and Nagoya covering a distance of 286 km. The travel time would be cut down by half in comparison to the current bullet trains. But Maglevs have a big problem; they’re extremely expensive to operate. The 286 km Tokyo-Nagoya stretch would require a $100 Billion investment. On comparison, the 508 km long Mumbai-Ahmedabad bullet train project is expected to cost $17 Billion.

日本的磁悬浮试跑时跑出了603公里每小时的速度。

运营速度大约会是500公里每小时，从东京到名古屋的磁悬浮全长286公里。

旅行时间会比现在的高铁减半

磁悬浮有一个大问题，就是成本很高。

东京到名古屋286公里的磁悬浮造价会达到1000亿美元。

而孟买到艾哈迈达巴德全长508公里的高铁，耗资预计才170亿美元。

If you ask about India, I don’t think India will ever have a Maglev. By next 20 years, Hyperloops would materialise. They would offer much higher speed than Maglevs at a much lower cost. Until then India would focus on bringing more wheel based bullet trains. More and more cities would be connected with high-speed railways. But India could have Maglev if Hyperloops use this technology instead of what Elon Musk proposed.

我觉得印度不会修哪怕是一条磁悬浮。未来20年，超级高铁会出现。

超级高铁成本比磁悬浮低多了，速度却快多了。

超级高铁没到来之前，印度会专心发展轮轨高铁。

越来越多印度城市会被高铁连接起来。

As for all trains in India after 30 years, no they will not be Maglevs. By that time, I expect majority of the network to be upgraded at semi-high speed level. India could well have Rajdhani & Shatabdi trains which would run between 200–250 kmph. There will be express trains as we have today, there will be superfast trains with a higher MPS than today. New parallel tracks will be constructed in the high density regions, maybe dedicated for only semi-high speed trains.

30年后，印度火车还是印度火车，不会是磁悬浮。

到时候，我希望印度铁路网大部分升级为“半高铁”了

印度会有时速介于200-250公里每小时的Rajdhani和Shatabdi特快。

人口密集区会铺设双线铁路。

Maglevs are way too costly for any country, not only India. started commercial service of Shanghai Maglev in 2004 and have stalled the expansion plans for years. Japanese would be commercially deploying Maglev by 2027. Countries like UK, Australia, Malaysia/Singapore have cancelled Maglev proposals already due to high costs.

磁悬浮的成本太高了，不仅仅是印度修不起，其实任何一个国家都承受不起。

是2004年开通上海磁悬浮的，自那以后就没有延长磁悬浮。

日本磁悬浮要到2027年才会开通。

英国、澳大利亚、马来西亚和新加坡已经取消了磁悬浮项目，原因也是成本太高

Ramakrishnarao Inegenti, former Retired at Indian Railways (1970-2009)

It is not possible that all train's in India to be maglev ,because it required a lot of structural works to made and required an advanced technology. Maglev technology is on the of progress in the world and lots of things to be improve.

印度火车以后全部更换为磁悬浮列车，那是不可能的，这过程太麻烦了，技术要求很高。

磁悬浮技术还在发展完善中，还需要大量改进。

Prasanna Bhalerao, M.Sc. Physics & Electronics, Fergusson College, Pune

Extremely unlikely. Maglev is a completely different technology and will require replacement of exsting rails, new trains and coaches, etc. Maglev is extremely expensive - even more than Bullet Trains. Maglev was invented years ago but has not been implemented apart from some small metro routes.

不可能。磁悬浮技术和轮轨高铁技术完全是两码事，需要重新铺设线路。

磁悬浮成本太高了，比高铁的成本更高。

磁悬浮发明也没几年，只在一些较短路线上跑
