Afcons’ TBM Gears Up to Start Tunneling for Mumbai Ahmedabad Bullet Train Project

The Mumbai–Ahmedabad Bullet Train project reached a key milestone last week as Afcons Infrastructure received the parts of its first tunnel boring machine (TBM). The assembling of the TBM has begun in Navi Mumbai. 

The mixshield tunnel boring machine (TBM) is now under assembly at Shaft-3 of the project, located in the Sawli area of Ghansoli. This site features a specially constructed circular shaft measuring 39 meters in depth, designed to facilitate the TBM’s operations for the underground tunnel work.

This shaft will serve as the launching point for tunneling operations on the project’s 20.377 km underground section, Package C-2, which stretches from Bandra Kurla Complex Station to Shilphata Ramp.

Afcons’ tunnel boring machine (TBM), which has been supplied by Herrenknecht AG, will be the largest ever deployed TBM in India. It will feature a cutterhead with a diameter of 13.56 meters. The machine had remained in China for more than a year due to export restrictions imposed by the Chinese government, delaying its arrival for the Mumbai–Ahmedabad Bullet Train project.

From Sawli, this TBM will be commissioned to tunnel towards Vikhroli. Along with another machine, it will be used to construct a 16 km single-tube tunnel. Recently, on September 20, a 4.88 km tunnel connecting Ghansoli and Shilphata in Maharashtra was successfully completed using the New Austrian Tunnelling Method (NATM). This tunnel forms part of the planned 21 km underground section between Bandra-Kurla Complex (BKC) in Mumbai and Shilphata, while the remaining portion will be constructed using TBMs.

Delhi Metro Invites Bids for Supply of 500 Million Units of Renewable Energy

Delhi Metro Invites Bids for Supply of 500 Million Units of Renewable Energy 

In yet another major push towards the adoption of renewable energy sources for the operation of the Delhi Metro, the Delhi Metro Rail Corporation (DMRC) has invited bids for the supply of 500 Million Units (MUs) of renewable energy every year.  

DMRC has always been committed to providing a clean, green, and hassle-free public transport facility to its commuters. To meet a significant portion of its existing power demand, DMRC is already taking approximately 350 MUs annually from Rewa Solar Park and generating 40 MUs annually from Rooftop Solar Plants installed on the roofs of stations, depots, and staff colonies of DMRC. The present Renewable energy penetration in DMRC is about 33 percent of the total power usage during the operational hours and nearly 65 percent during daytime Metro operations.

image 4

The Delhi Metro is inviting bids to select a ‘Solar Power Developer’ for setting up a Grid connected Captive Generating plant along with Battery Energy Storage System (BESS) anywhere in India to supply 500 MUs of renewable energy every year to DMRC in Delhi and NCR. This is a step in supporting India’s transition towards a cleaner and more resilient energy future.

DMRC’s primary objective of calling the bid for more Renewable Energy (RE) power is to increase the share of RE power in its power portfolio from the current 33% to greater than 60% of its total energy requirement (including Phase-IV network expansion). With this initiative, DMRC will become the first Metro rail project in India to avail greater than 60% Renewable power for its transition towards sustainable and low-carbon operations.

image 5

The stipulated completion period of the project shall be 15 months from the date of award, and the Power Purchase Agreement period will be of 25 years. The bid process shall be implemented as per approved government norms. This is an effort by DMRC to contribute towards the Government of India’s proposed five-fold strategy of “Panchamrit”, which comprises five climate action goals announced at COP 26.

Bullet Train Project: 10th Steel Bridge Completed in Ahmedabad 

The Mumbai–Ahmedabad Bullet Train project has achieved another milestone with the successful launching of its 10th steel bridge in Ahmedabad, Gujarat. The 60-meter-long bridge was installed over a Western Railway facility (laundry) situated adjacent to existing railway tracks. 

image 2

Following several months of detailed planning and logistical preparation, the bridge launching was executed with remarkable precision in just seven hours. This is the first steel bridge launched within the Ahmedabad district for the project.

For the transverse launching process, the bridge was pre-assembled at a height of 16.5 meters above ground level on temporary trestles. It was then side-slewed into its final position using two semi-automatic jacks, each with a 200-ton capacity, supported by locking trolleys to ensure stability and control.

image 3

The bridge weighs approximately 485 metric tons and measures 12 meters in height and 11.4 meters in width. It was fabricated at a specialized workshop in Wardha (Nagpur, Maharashtra) and transported to Ahmedabad using custom-designed trailers. The bridge construction involved the use of around 20,360 Tor-Shear Type High Strength (TTHS) bolts, complemented by a C5 protective paint coating system and elastomeric bearings to enhance durability and reduce vibration impact.

A total 28 steel bridges are planned for the entire corridor, out of which 17 are in Gujarat and 11 in Maharashtra.
