Why has the Mumbai-Ahmedabad bullet train project been delayed? Ashwini Vaishnaw answers
Mumbai Ahmedabad Bullet Train Project: The National High-Speed Rail Corporation Limited is rapidly progressing to operationalise the country's first bullet train network between Mumbai and Ahmedabad. Recently, in a written statement in Lok Sabha, Railway Minister Ashwini Vaishnaw stated that Mumbai Ahmedabad High Speed Rail (MAHSR) corridor is planned to be completed by 2027. 'The Gujarat portion of the corridor between Vapi and Sabarmati is planned to be completed by December 2027. The entire project {Bandra Kurla Complex (BKC) to Sabarmati section} is expected to be completed by December 2029,' the minister said. One of the biggest questions now is why this ambitious project has been delayed. Initially, the Ministry of Railways had planned to make the first section of the MAHSR corridor operational by 2026. Interacting with the media on February 23, 2024, Vaishnaw said, 'This is the country's first High Speed Corridor project…To further speed up the project certain innovations have been made. Instead of working only at one place at a time, work has begun from four places parallelly. It is targeted that the first section of the High Speed Rail corridor between Surat and Bilimora will begin functioning in July/August 2026. Subsequently one after the another other sections will open.' During the ongoing Monsoon session of Parliament, Lok Sabha MP Jai Prakash asked Railway Minister about the current status of the Mumbai-Ahmedabad High Speed Rail Corridor and whether the country's most ambitious rail project is running behind schedule. In response, Vaishnaw said the MAHSR project was delayed due to setbacks in land acquisition in Maharashtra, which impacted the project till 2021. 'The delay in land acquisition in the State of Maharashtra impacted the project till 2021. Thereafter, the land acquition picked up, currently, entire land (1389.5 Ha.) for MAHSR project has been acquired,' the minister said on July 6. He also stated that all Statutory Clearances relating to wildlife, Coastal Regulation Zone (CRZ) and Forest clearance have been obtained. 'All the civil contracts of the project have been awarded. Out of total 28 tender packages, 24 tender packages have been awarded. All 1651 utilities have been shifted,' Vaishnaw added. Out of total 12 stations, foundation works has been completed at 8 stations – Vapi, Bilimora, Surat, Bharuch, Anand, Vadodara, Ahmedabad and Sabarmati. In Maharashtra section, foundation work is in progress at 3 stations (Thane, Virar, Boisar) and excavation work at BKC station is near completion and Casting of base slab started. 16 river bridges have been completed. Work is in advance stage at 5 major river bridges (Narmada, Vishwamitri, Mahi, Tapti and Sabarmati) in Gujarat and in progress in 4 river bridges in Maharashtra. Work on Depots (Thane, Surat and Sabarmati) is in full swing. Work of the only tunnel in Gujarat has been completed. The work of the under-sea tunnel (21Km approx.) has started. Out of which, 4.0 km tunnel between Ghansoli and Shilphata in Maharashtra has been completed. Anish Mondal is a business journalist with over nine years of experience.

Mumbai-Ahmedabad bullet train project chugs ahead: Ghansoli-Shilphata section of 21 km undersea tunnel ready
Marking a major milestone in the Mumbai-Ahmedabad bullet train project, the first section of the 21-km undersea tunnel between Bandra-Kurla Complex (BKC) and Thane was opened recently, an official statement said. Out of the total 21 km of tunnel, 5 km between Shilphata and Ghansoli in Maharashtra was constructed using the New Austrian Tunnelling Method (NATM), while the remaining 16 km is being built using Tunnel Boring Machines (TBMs). The tunnel also includes a 7-km-long undersea section beneath Thane Creek. The statement said the high-speed train project recently achieved another milestone: constructing a 310 km viaduct. 'Track laying, construction of overhead electrical wires, stations, and bridges is going on at a rapid pace,' it added. The entire 508 km Mumbai-Ahmedabad bullet train corridor – 352 km in Gujarat and 156 km in Maharashtra – is being developed with Japanese Shinkansen technology. After the completion of the project, next-generation E10 trains are likely to run on the high-speed tracks. 'Japanese Shinkansen is currently running E5 trains. Next generation trains are E10. 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,' the statement said. It is noteworthy that E10 will be introduced simultaneously in India and Japan. The success of the Mumbai-Ahmedabad High-Speed Rail (MAHSR) project is laying the foundation for future bullet train corridors in India. As per the statement, future corridors are also under active consideration. The work on the Mumbai-Ahmedabad high-speed bullet train project is going on in full swing in Maharashtra, with major structural and tunnelling milestones being achieved, the National High-Speed Rail Corporation Limited (NHSRCL) said on Saturday. According to the NHSRCL, work on all three elevated stations in the state — Thane, Virar, and Boisar — is advancing swiftly, and the first slabs for Virar and Boisar stations have recently been cast.

2.7 km long continuous tunnel completed with first breakthrough in 21 km tunnel between BKC and Shilphata
Shilphata (Maharashtra) [India] July 11 (ANI): On July 9, the first breakthrough was achieved in the 21 km long tunnel being constructed between Bandra-Kurla Complex (BKC) and Shilphata in Maharashtra, marking the successful completion of a 2.7 km continuous tunnel section. Out of the total 21 km tunnel, 5 km is being constructed using the New Austrian Tunnelling Method (NATM) between Shilphata and Ghansoli, while the remaining 16 km will be built using Tunnel Boring Machines (TBMs). The tunnel also includes a 7 km long undersea section beneath Thane Creek. To expedite tunnelling in the NATM portion, an Additionally Driven Intermediate Tunnel (ADIT) was constructed, allowing simultaneous excavation towards Ghansoli and Shilphata sides. So far, about 1.62 km has been excavated from the Shilphata side, and the total progress in the NATM section stands at approximately 4.3 km. 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. The work on the Mumbai-Ahmedabad high-speed bullet train project is going on in full swing in Maharashtra, with major structural and tunnelling milestones being achieved, according to the National High-Speed Rail Corporation Limited (NHSRCL) said on Saturday. According to the NHSRCL, work on all three elevated stations in the state, Thane, Virar, and Boisar, is advancing swiftly, and the first slabs for Virar and Boisar stations have recently been cast. Across the alignment, pier foundations and pier works are underway at various locations, with approximately 44 km of piers cast to date. In the Palghar district, viaduct construction has also commenced using full-span box girder launching technology, starting from the Dahanu area. Additionally, the excavation of seven mountain tunnels in the Palghar district is actively in progress, demonstrating the project's engineering scale and complexity. Bridge construction has also kicked off at three major rivers: Vaitarna, Ulhas, and Jagani, further contributing to the corridor's critical infrastructure. An important component of the project is the 21-kilometre-long underground and undersea tunnel connecting the Mumbai Bullet Train station at Bandra-Kurla Complex (BKC) to Shilphata. Of the 21 km tunnel, 16 km is being excavated using Tunnel Boring Machines (TBMs), while 5 km is being executed using the New Austrian Tunnelling Method (NATM). The tunnel includes a 7 km undersea stretch beneath Thane Creek, marking a significant feat in Indian tunnelling history. So far, approximately 4.1 km of tunnel heading has been achieved through NATM from the Shilphata site, and two concurrent faces have been developed from the ADIT portal. In terms of vertical construction, base slab casting at the Vikhroli shaft (56 meters deep) and Sawli shaft (39 meters deep) has been completed. Additionally, sludge treatment plants are being installed at shaft locations, and the Mahape tunnel lining casting yard is actively producing tunnel lining segments. For the under-construction Mumbai Bullet Train station at Bandra Kurla Complex, 80% of the excavation work has been completed. Base slab casting at 100 ft below ground level has already started at both ends of the station site, NHSRCL added. (ANI)
