Ahmedabad/Anand/SuratIn September 2017, simply two months earlier than the Gujarat Meeting elections, Prime Minister Narendra Modi and his then Japanese counterpart Shinzo Abe laid the inspiration stone for the formidable 508-km Mumbai-Ahmedabad bullet practice mission in Ahmedabad. Modi referred to as it a “image of a brand new India”, whereas the opposition dismissed it as an “electoral bullet practice”.
After greater than 5 years, because the western state gears up for an additional meeting election, the 348-km-long Gujarat part of the mission has gathered momentum, with groups of engineers and staff working in 24×7 shifts. The rationale has labored to make up for the misplaced time. Land acquisition points and the pandemic, amongst different issues.
When ThePrint visited 5 mission websites within the state a fortnight in the past, a number of thousand staff and engineers, with the assistance of a few of the most refined equipment, had been shaping the high-speed hall – ghat by ghat, girder by girder.
On the casting yards south of Anand and Navsari in central Gujarat, large girders, every weighing about 975 metric tons, had been being forged. These prestressed concrete and metal buildings are being constructed on piers on which the tracks for the bullet practice will probably be laid.
In Surat, engineers had been busy overseeing the complicated technique of constructing a rail bridge over the Tapi River, whereas within the metropolis, a diamond-shaped bullet practice station was in superior phases of building.
In Ahmedabad, mission staff mentioned that many of the work on the multimodal transport hub to attach the bullet practice station to the Metro, Bus Fast Transit System (BRTS), and Sabarmati railway station had been accomplished.
The “status” related to the mission has attracted a various labor drive together with engineering consultants from throughout the nation.
An engineer at a mission web site in Surat mentioned, “Individuals of varied ranges – from supervisors to electricians and welders – have left their jobs in building initiatives in Dubai and different Gulf international locations and returned to work on the bullet practice mission. are.”
There may be additionally a world taste, with Japanese executives and engineers incessantly visiting mission websites. “They (Japanese) are actually in search of an workplace in Ahmedabad,” mentioned a senior official of the Nationwide Excessive Pace Rail Company Restricted (NHSRCL) in Sabarmati.

overcoming gradual begin
Primarily based on know-how much like the Shinkansen – the Japanese bullet practice – however modified to swimsuit Indian circumstances, the Mumbai-Ahmedabad practice will run at a pace of 320 kmph and canopy a distance of 508 km in beneath three hours.
The most important stretch of the hall – 348 km – is in Gujarat, whereas 156 km falls in Maharashtra and 4 km falls in Dadra and Nagar Haveli.
The mission is being carried out by NHSRCL, a particular function automobile set as much as finance, construct, preserve and handle high-speed rail corridors.
Eighty % of the funding for the mission is thru a mushy mortgage from the Japan Worldwide Cooperation Company (JICA) of the Japanese authorities, with the remaining price. The share is being shared by the Central Authorities and the Governments of Gujarat and Maharashtra within the ratio of fifty:25:25.
Whereas the unique December 2023 deadline for the bullet practice mission will finish and the price of the mission is prone to exceed Rs 1.08 lakh crore estimated within the feasibility examine, the way in which ahead seems promising.
One of many greatest points surrounding the mission – each in Gujarat and Maharashtra – was land acquisition. However now, greater than 98 per cent of the required land has been acquired in Gujarat, and 95.4 per cent in Maharashtra. All essential land has been acquired in Dadra and Nagar Haveli.
The federal government is but to set a closing deadline for all the 508-km mission, however the 50-km stretch between Surat and Bilimora in Gujarat has been set for August 2026.
Whereas work has began in Maharashtra after a delay of years, civil work in Gujarat is progressing at a great tempo. All of the contracts have been awarded within the state and the development of bridges (a sort of bridge) on bridges, stations and tracks is occurring in full swing.
man and machine
What’s most hanging in regards to the primary civil works of the mission is the size and complexity of the enterprise, be it girders being constructed at casting yards, piers beneath building at alignment websites, or large equipment, most of that are indigenously constructed .
In Anand, round 6,000 staff work round the clock in shifts on the casting yard to satisfy their goal of setting up 734 girders, beneath the watchful eye of Chief Mission Supervisor Pradeep Ahirkar, in control of civil and constructing building works of 88 km. viaducts and a station in Anand.
He informed ThePrint that crucial half in all the course of is the casting and launching of the girders.
“The size of a girder is 40 meters and it weighs about 975 metric tons. The casting of the girders have to be of top of the range and their launching have to be exact. That is the inspiration on which the bullet practice will run and is crucial stage,” he defined.
He mentioned, 60 girders have been constructed up to now, out of which 38 have been launched at piers.
Transferring and inserting the girders on the piers is a activity assigned to a set of highly effective machines.
Take straddle carriers, for instance. Manufactured at mission contractor Larsen & Toubro’s plant in Kancheepuram, Tamil Nadu, they arrive with 80 large tyres, 20 axles and might elevate a load of round 1,100 metric tons. They’re getting used to maneuver the girders from one place to a different.
Then there may be the bridge gantry, which lifts the girder off the bottom and locations it on prime of the girder transporter. The latter, a extra large machine, performs the essential activity of shifting the girder from the bridge gantry areas to the launching gantry.
The launching gantry then lifts the girder from the girder transporter and launches it on the piers. Solely after this all of the girders will probably be positioned on the piers and examined that the monitor laying work can begin.
The Anand part of the mission covers an extension of 88 km. “Until now, we now have accomplished about 73 km of basis work and 45 km of pile cap for pillar building. Apart from, 35 km of piers have already been constructed on this part,” Ahirkar mentioned.
General, out of 348 kms in Gujarat, 100 kms of piers have been constructed. Other than this, the work of 9.2 km viaduct has been accomplished.
There’s a studying curve and far stays to be performed, however Ahirkar is optimistic, he mentioned. “We’ll get it performed on time,” he informed ThePrint.
A railway engineer, Ahirkar left his job as an officer of the Indian Railway Service of Engineers (IRSE) cadre in Western Railway and joined NHSRCL in 2017.
In actual fact, many of the senior officers of NHSRCL have both come on deputation or left their jobs in Indian Railways and different allied organizations like IRCON (earlier often known as Indian Railway Building Firm) and Delhi Metro Rail Company (DMRC). Is.
A deputy mission supervisor posted at Navsari Casting Yard mentioned, “There’s a large status issue concerned in working for India’s first bullet practice mission, the place 2.5 km of steady viaduct has been accomplished.
An MTech graduate from IIT Kanpur, this Deputy Mission Supervisor labored for over a decade in Delhi, Pune and Nagpur Metro Rail initiatives earlier than becoming a member of NHSRCL.
His sentiments in regards to the mission’s “repute” had been echoed on different websites as properly.
For instance, an L&T civil engineer, who hails from Andhra Pradesh and is working in Surat, mentioned the mission was assured to “improve the profession graph” of everybody engaged on the mission.
“It’s difficult when it comes to scale, and there’s a lot of studying concerned as we’re utilizing this know-how for the primary time in India. It’s presently probably the most superior railway infra mission on this planet.”
Advanced know-how, in depth coaching in Japan
The bullet practice mission entails shut cooperation between India and Japan.
The E5 Shinkansen sequence bullet trains that will probably be put into service will probably be manufactured by Japan’s Kawasaki Heavy Industries and Hitachi, however the civil work within the Gujarat part is being performed by Indian contractors.
Whereas the slabs required for laying the monitor are being made in India, the monitor elements will come from Japan.
The engineers chargeable for the operation and upkeep of the bullet practice have began coaching in batches in Japan. Engineers have additionally been despatched to Japan for civil work coaching.
“The civil work is complicated, together with monitor laying and building of bridges. We’ve got not used this system earlier than. Our individuals, each engineers and staff, are present process in depth coaching in Japan,” mentioned a senior NHSRCL official concerned in constructing a bridge over the Tapi river in Surat.
A coaching heart for engineers has additionally been arrange in Vadodara. “A simulator of the bullet practice engine has been introduced from Japan for coaching functions,” the official mentioned.
Probably the most complicated substructure being constructed on the Gujarat part presently consists of bridge buildings over 4 rivers – Tapi, Narmada, Mahi and Sabarmati.
“Constructing a pier on a river is difficult. It entails complicated geotechnical investigations. To start with, the inspiration of the properly needs to be laid. Then piers will probably be put in, over which the girders will probably be launched. Lastly, the monitor will come on the girder,” mentioned a senior NHSRCL official overseeing the development of the bridge over the Tapi river.
closest to completion
A tall, stately constructing with a big stainless-steel mural depicting Mahatma Gandhi’s Dandi March grabs fast consideration as one passes via the Sabarmati space in Ahmedabad. It’s simply reverse to the Indian Railways Sabarmati Railway Station adjoining it.
The brand new constructing is the Sabarmati Multimodal Transport Hub. Because the Mumbai-Ahmedabad high-speed rail hall will terminate right here, it will likely be linked to the prevailing Sabarmati railway station, metro station and bus fast transit system.
Whereas the completion of the terminal station will take time, work on the hub is nearing finalization.
Arun Kumar Singh, chief mission supervisor, Sabarmati Multimodal Hub, mentioned, “Round 90 per cent of the work has been performed.” He mentioned he anticipated it to be accomplished by February 2023.
“The multimodal hub is designed to satisfy 1.5 lakh footfalls. Work is underway on a three-foot overbridge, which can join the hub with the Metro, BRTS and the railway station.
At current, round 850 staff, largely from Uttar Pradesh, Bihar, Jharkhand, West Bengal and Odisha, are working on the web site. “Work began in Could 2019. However then Kovid hit. Throughout that point the variety of staff was decreased to 250. There was a delay due to that,” Singh mentioned.
The Gujarat part can have eight stations – Vapi, Bilimora, Bharuch, Vadodara, Anand, Ahmedabad, Sabarmati and Surat. All are in numerous phases of building, with Surat’s bullet station not removed from completion.
Nicknamed Surat because the Diamond Metropolis of India, the station, which is anticipated to be prepared by April 2024, is designed within the form of the dear gem.
