What is the present status of the much hyped "Bullet Train" between Ahmedabad and Mumbai? Is the project on going, or put on hold?

之前被大肆炒作的艾哈迈达巴德至孟买的“高铁项目”现状如何？这个项目是在建呢，还是暂停了？

以下是Quora网友的评论：

Subramaniam Duraisamy

Short Answer- Work In Progress, or as they say here in IT parlance- WIP. Which is the case for many infrastructure projects in India :)

简单回答是—仍在进行，或者用IT术语来说——工作中。印度的许多基础设施项目都是如此:)

Longish Answer:

The construction of this project is being undertaken National High Speed Rail Corporation Limited (NHSRCL) which has been founded and set up in 2016, for overseeing the completion of high speed rail projects [which includes bullet trains, Vande bharat express] and other semi-high speed rail projects.

NHSRCL has divided this project construction into 8 parts or 8 zones along the proposed Mumbai- AHD route. This is a snapshot from their Wiki page of the contractors who are awarded work on each part.

详细回答是：

这个项目的建设由国家高速铁路有限公司负责，该公司成立于2016年，负责督办高速铁路项目(包括子弹头列车、Vande bharat特快列车)和其他半高速列车项目的完工。

国家高铁公司将该项目的建设分为了8个部分或8个区域，沿着拟议的孟买- 艾哈迈达巴德路线。这是维基网上的网页快照，每个部分的承包商都已分配了工作。

The challenging part of constructing this project is the 7 km under-sea tunnel on the Thane Creek area where the river meets the sea. From the website of NHSRCL:

Proposed high speed rail corridor will pass through Thane Creek in Mumbai. Since this area is a protected sanctuary for flamingo and nearby mangroves, rail tracks will be made undersea through a tunnel, thus ensuring no disturbance to exsting ecosystem. This tunnel will be longest rail transport and 1st undersea tunnel of India. Tunnel will be a single tube with 13.2 meters diameter to be executed by both NATM and TBM methods in different sections. An underwater static refraction technique was used for the survey work and is now completed.

这一项目的建设中最难的部分是位于河流入海口塔恩河地区的7公里长的海底隧道。根据国家高速铁路有限公司的网站：

拟议中的高铁通道将穿过孟买的塔恩河。由于该地区是火烈鸟和附近红树林的生态保护区，因此将在海底修建隧道，铺设铁轨，不影响现有的生态系统。这条隧道将是印度最长的铁路运输和第一条海底隧道。隧道直径将达13.2米，在不同的路段分别采用新奥地利隧洞施工法和隧道掘进机方法施工。前期调查工作使用了水下静态折射技术，现已完成。

NHSRCL has proposed two types of trains in this route. The first type is a “Rapid train” which will stop only at 2 stations- Surat and Vadodara. The second type is the slower type which stops at all 6 stations in the route. The “Rapid Train” would take 2 hours and 6 minites, whereas the slower train would take 2 hours and 58 minutes to complete the journey. According to NHSRCL, there are 70 daily services [35 up and 35 down] with the first service begng at 6AM and last one ending at midnight. The estimated ridership is likely to be 36000 passengers daily.

国家高铁公司建议在这条线路上运行两种类型的列车。第一种是“快速列车”，只在苏拉特和瓦多达拉两个车站停靠。第二种是速度较慢的列车，停靠6个车站。“快速列车”的运行时间为2小时6分钟，而慢速列车的运行时间为2小时58分钟。根据国家高速铁路公司的数据，每天将发送70个班次(往返各35个班次)，首班车于早上6点发车，末班车将于午夜到站。预计客流量约为每天36000名乘客。

2022年2月，古吉拉特邦完成100%的土地征用，马哈拉施特拉邦完成60%的土地征用，L&T获得了一份价值250亿的合同，修建高架桥并建设瓦多达拉火车站。

To summarize:

总结如下：

Land acquisition is happening - complete in one state and 60% done in another.

Contracts are awarded to L&T for station constructions.

Contracts awarded to IRCON for supplying tracks

Viaducts and piers for undersea tunnel are started to be construction.

土地征用尚在进行中—一个邦已经完成，另一个邦已完成60%。

L&T公司获得了火车站的建设合同。

印度铁路建设局获得了铁轨的供应合同

海底隧道高架桥、桥墩已开工建设。

So yes, as I said in the begng- WIP. Estimated date of completion October 2028

所以，像我一开始说的，项目正在进行中。项目的预计完成日期为2028年10月。

Balaji Viswanathan

The work got delayed by Covid-19 but was resumed in 2021.

On the Gujarat side, land aquisition is mostly done and the focus is on building the piers for the elevated track. These are completed piers in the Anand district.

这项工程因为新冠肺炎推迟了进度，但于2021年恢复施工。

在古吉拉特邦方面，土地征用的工作已完成了大部分，目前的工作重点是为高架轨道建造桥墩。这些是阿南德地区已完工的高架桥墩。

In Nov 2021, an indigenously produced full span box girders were launched.

In May 2022, they announced the advanced stages of construction of the multimodal rail complex at Sabarmati that has design elements “inspired” from the Dandi march.

What is the current status of bullet train in india?

I am from National Rail and Transportation Institute(NRTI) Inside the National Academy of Indian Railways(NAIR), Vadodara where the Bullet train Demo Track construction is going on.

I can talk about the Construction in Vadodara. Since it will be a station between Mumbai to Ahmedabad project in Vadodara, There is Demo track is being built for training purpose here As I talked with them.

印度高铁的现状如何？

我来自印度国家铁路学院的印度国家铁路和交通研究所，瓦多达拉的高铁试验轨道正在建设中。

我可以谈谈瓦多达拉的建设情况。这里是孟买到艾哈迈达巴德之间的一个车站，我与他们交谈时，这里正在建造的是用于培训的试验轨道。

However, it was not allowed to go over tracks without Helmet but later on the In charge of the construction who was Japanese took us there. He seems to be very Humble and interested to talk and told about that How this will work. He also told that the Initial model of the bullet train that will be brought in India will be Shinkansen. Whose speed will be 320km/hr

There was two track there one was straight and one was bend for the trial purpose. Also, I asked the question：

Can these trains run on conventional tracks?

但不戴头盔不得进入轨道现场，后来负责建设的日本人带我们去了。他似乎很谦虚健谈。他告诉我们即将引入印度的高铁的初始模型就是日本的新干线，时速可达320公里/小时。

现场有两条轨道，一条直的，一条弯的，用于试验。我还问了一个问题：

这些列车能在传统铁轨上运行吗？

They told Most high-speed trains to run on conventional tracks similar to conventional gauge systems but built with stronger material. The train on such a track is likely to have two synchronized engines (power cars), one at either end. Most receive power from roof-mounted pantographs and overhead supply lines. A large part of route alignment is kept straight to support high speed. Although in most countries these trains operate on dedicated tracks, many can also run on conventional tracks at reduced speeds.

他们说大多数高速列车可以在类似传统轨距系统、但采用了更坚固的用料的轨道上运行。在这种轨道上运行的火车可能有两个同步引擎(动力车厢)，分别位于列车的两端。大多数由安装在车顶的集电弓和接触网馈电线路接收电力。大部分路线会保持直线来保证高速行驶。虽然在大多数国家，这种列车会在专用轨道上运行，但也可以降低速度在传统轨道上行驶。

Most of the material is being imported from Japan Right now these things were there which were imported from Japan.

Here are images of the first consignment that is arrived from Japan Even the Rails are also being imported from the Japan.

大部分材料都是从日本进口的。

这些是从日本运来的首批货物的图片，就连铁轨也是从日本进口的。

The project is harshly affected due to Covid-19. But now it is in full swing in Gujarat section. 100% land acquisition completed in Gujarat. Land acquisition in Maharashtra is still pending.

由于新冠肺炎爆发，该项目严重延期了。但现在，古吉拉特邦地区的施工正如火如荼地进行着。古吉拉特邦已完成100%土地征用。马哈拉施特拉邦的土地征用仍悬而未决。

World class Shinkasen technology is being used to build India's first bullet train project. With the Japanese design and technology work is going on at a fast speed. For the launching, NHSRCL is using Full span launching Method at many places along the alignment, in which a 40m span is being Erected by Bridge gantry, Girder transportor, Launching Girder and Straddle carrier. This is the first time in India where the launching in done in this way.

印度首个高铁项目采用了世界级的新干线技术。有了日方的设计和技术，建设工作正在快速推进。在本次工程中，国家铁路建设公司在沿线多处采用全跨吊运方式，由桥梁龙门架、运梁机、吊梁机架设跨度为40m的吊运桥。这是印度第一次以这种方式进行吊运。

Many new technology is being used for the first time in this project. It's going to be one of the finest and unique engineering Marvel which is build in India in the history ever.

这个项目首次采用了许多新技术，将成为印度历史上建造精度最高、独一无二的工程奇迹之一。

The upcoming bullet train in India has now been postponed to December 2028. Why?

It is no surprise as all Indian projects delay and we have no national determination to keep our projects on schedule and mindfulness for the cost escalations or impacts on GDP or on any failures to keep international commitments. This project was conceptualized when LK Advani was Dy PM. It was supported by Dr MMS and later the PM NM made it his project and staked his name by resorting to laying foundation in 2017. This yet another big failure by the BJP led govt. to deliver in spite of the willing support from Japan.

印度高铁项目的完工日期推迟到2028年12月。为什么呢？

印度所有的建设项目都延期了，我们没有保证项目如期进行的国家意志，也没有意识到成本升级或对GDP的影响，或无法履行国际承诺的负面影响，我们早都见怪不怪了。阿德瓦尼担任总理时就设想过这个项目，并得到了辛格博士的支持，后来莫迪总理正式提出这个项目，2017年开始动工，成了莫迪的一项功绩。但即便有了日本的支持，这项工程还是成了人民党政府的又一次重大失败。
