The first breakthrough in the under construction 21 km-long tunnel between Bandra Kurla Complex (BKC) and Shilphata for the Mumbai-Ahmedabad bullet train corridor was achieved on Thursday when a 2.7 km-long continuous tunnel section was completed.
The 2.7 km stretch is located in Ghansoli, 400 metres away from Parsik Hills. 'The achievement of the first tunnel breakthrough is a major milestone in the civil works of the corridor in Maharashtra,' said a National High-Speed Rail Corporation Limited (NHSRCL) official.
According to NHSRCL officials, the 21-km tunnel has two different construction processes. The new austrian tunnelling method (NATM) is being used for about 5 km of the Shilphata-Ghansoli section, while tunnel boring machines (TBMs) are being utilised for the remaining 16 km, including a 7-km underwater span under Thane Creek.
The Mumbai-Ahmedabad bullet train project under the NHSRCL has various intricate engineering features, such as viaducts, tunnels, stations and depots along the corridor through Gujarat and Maharashtra.

Bullet train: First section of the 21-km undersea tunnel sees breakthrough

India's bullet train project achieved a major milestone Monday when the first section of the 21-kilometre undersea tunnel between BKC (Bandra-Kurla Complex) and Thane made a breakthrough. The 2.7-km tunnel section, part of the Mumbai-Ahmedabad bullet train project, has been constructed between Ghansoli and Shilphata in Maharashtra. Out of the total 21 km, 5 km is being constructed using the New Austrian Tunnelling Method (NATM) between Shilphata and Ghansoli, while the remaining will be built using Tunnel Boring Machines (TBMs). The tunnel also includes a 7-km-long undersea section beneath Thane Creek, the ministry of railways said in a statement. To expedite tunnelling in the NATM portion, an Additionally Driven Intermediate Tunnel (ADIT) was constructed, allowing simultaneous excavation towards Ghansoli and Shilphata sides, the statement added. Comprehensive safety measures have been implemented at the site, including ground settlement markers, piezometers, inclinometers, strain gauges, and biometric access control systems to ensure safe and controlled tunnelling activities without disturbing nearby structures. India's first high-speed train project is now moving faster. Track laying and the construction of overhead electrical wires, stations, and bridges are also going on rapidly. The construction work in Maharashtra, which was delayed earlier, has also picked up pace. In parallel, the progress on procurement of systems for operations and control is also going well, the statement said. Indian Railways is developing the country's first 508-km bullet train project using Japanese Shinkansen technology. Accordingly, it has secured approval from Japan to use its latest generation E10 Shinkansen trains in the Indian project. Japan is currently running E5 trains. Next generation trains are E10, which Japan will also introduce later. In the spirit of strategic partnership between Japan and India, the Japanese government has agreed to introduce E10 Shinkansen trains in the Mumbai-Ahmedabad Bullet train project. It is noteworthy that E10 will be introduced simultaneously in India and Japan, the ministry of railways said in the statement. Shinkansen technology is expected to set new benchmarks for speed, safety, and reliability. This reflects the deep strategic and technological cooperation between India and Japan, the statement said. The success of the Mumbai-Ahmedabad High-Speed Rail (MAHSR) project is laying the foundation for future bullet train corridors in India. Some of the corridors under consideration are Delhi-Varanasi, Delhi-Ahmedabad, Mumbai-Nagpur, Mumbai-Hyderabad, and Chennai-Mysore, among others.

Gadkari's mega mobility plan: Electric buses, ropeways on fast track

Union Minister Nitin Gadkari has unveiled an ambitious roadmap for next-generation mass mobility in the country, which includes electric rapid transport, hyperloop in urban areas and ropeways, cable buses and funicular railways in inaccessible terrains. In an interview with PTI, the Union Minister of Road Transport and Highways said India's transport sector is undergoing a major transition, with initiatives like tree bank, mobile-based driving tests, and flex-fuel engines by 11 leading automakers in the pipeline. Also on the agenda are plans to upgrade 25,000 km of two-lane highways to four lanes, establish an electric mass rapid transport network across major routes and scale up road construction to 100 km per day. 'We are driving innovation. A revolution in mass mobility is underway,' Gadkari said. 'Work is progressing at a war footing to transform how India travels, with a focus not just on metropolises but also on remote, inaccessible rural areas. We're building ropeways, cable cars and funicular railways across 360 locations, including Kedarnath. Work has already started on 60 of these projects,' he said. Funicular railways are a system that combines elevator and railway technologies to efficiently transport people and goods up and down inclines. These are particularly useful in mountainous or hilly areas. Gadkari said the cost of these projects ranges from ₹200 crore to ₹5,000 crore and once completed, they will change the face of India. The minister added that improved road infrastructure will not only boost the economy but will also help in propelling growth and creating jobs. 'I am more than confident that in a year's time, our highways will match the standard and quality of US roads that I have been emphasising,' he said, adding that days are not far off when metropolises will have cable-run buses, electric rapid mass transport buses with aeroplane-like facilities. Gadkari said pilot projects like Metrino pod taxis, hyperloop systems, and pillar-based mass rapid transport are in the pipeline for cities like Delhi and Bengaluru. 'Technology and investors are both coming in. It will be a revolution,' he said. The minister said, 'Eleven companies, including Tata, Toyota, Hyundai and Mahindra, have agreed to build flex-fuel engine vehicles that will reduce dependence on fuel imports as well as fossil fuel." Flex-fuel vehicles are equipped with internal combustion engines that can operate on more than one fuel. They are primarily meant to run on ethanol and methanol or a blend of biofuels and on conventional fuels such as petrol or diesel. Gadkari said India is working on 25,000 km of road upgrades for converting two-lane roads into four-lanes and 'we plan to build 100 km of roads per day – this is our target, not a declaration,' he clarified. The length of national highways was 91,287 km in 2013-14 and there has been an increase of about 60 per cent in the length of NHs to 1,46,204 km, he said. The length of National High-Speed Corridors (HSC) has expanded from 93 km in 2014 to 2,474 km at present, he said. New technologies, like precast construction, three-ft road barriers, and AI-based road safety tools, including drones and camera monitoring systems, are being introduced to boost efficiency and safety. 'We plan to plant 20–25 crore trees along highways, with an aim to transplant old trees and replant five for every one cut.' Talks for a tree bank are in advanced stages with the Ministry of Environment and once a go-ahead is received, full-fledged work will start, the minister said. Speaking about electric rapid transport, Gadkari said a tender has been floated for a 135-seater electric bus in Nagpur as a pilot project. The bus will feature executive-class seating, air-conditioning, and airline-grade amenities, capable of running at speeds of 120–125 km/hr. It will recharge in 30–40 minutes at designated stops and is expected to cost 30 per cent less than traditional diesel buses while offering significantly lower emissions, he said. 'Once the trial is successful, we plan to introduce similar buses pan-India, including on routes like Delhi-Chandigarh, Delhi-Dehradun, Delhi-Meerut, Delhi-Jaipur, Mumbai-Pune, Mumbai-Aurangabad and Bangalore-Chennai, among others," he added. As many as 670 roadside amenities have already been approved, aimed at providing world-class facilities for both travellers and drivers across national highways, he said. The minister said India's transport sector contributes nearly 40 per cent to the country's air pollution, and emphasised that green mobility initiatives will not only help curb emissions but also significantly reduce the nation's annual fuel import bill of around ₹22 trillion. He further claimed that improved road infrastructure will help bring down logistics costs from 14 per cent of GDP to 9 per cent by the end of the year, enhancing overall economic efficiency.
