Video: Heavy Rain Triggers Landslide Near Tunnel Of Sevoke-Rangpo Rail Project
Heavy rain triggered a landslide near a tunnel of the under-construction Sevoke-Rangpo railway project on Tuesday, an official said, maintaining that there was no casualty or loss of railway assets. According to Northeast Frontier Railways (NFR), the landslide occurred near tunnel number 7 of the ambitious project that will connect Sikkim with the rest of the country through the railway network. A concrete structure guarding the approach slope of one of the tunnels of the key rail link project collapsed, showed a dramatic video. Officials said that due to rain and landslides, heavy machinery and workers were already removed from the area. "An incident of slope failure due to landslide on account of heavy rainfall has taken place near Tunnel no. 7 of the Sevok-Rangpo project being constructed by IRCON in Sikkim. As per reports from the field, there are no casualties or injuries to any workers or general public. There is no loss of any machinery or railway assets. The landslide is about 30 metres away from the tunnel location and there is no danger to the tunnel," Kapinjal Kishore Sarma, spokesperson of Northeast Frontier Railway (NFR), said in a press statement. "In view of the heavy rainfall, precautionary measures had already been taken to remove the men and machinery from the site in advance. Work of debris removal and protection of the site is being started," the official added. The project involves 14 tunnels, 13 major bridges, and 5 stations, with 86% of the route passing through tunnels. The tunnel 7 is key to the project - the first underground Railway Station within the Indian Railways network, which will be Teesta Bazar Station comes in this tunnel, marking a pioneering step in the advancement of Railway infrastructure in the country. The main tunnel spans 3082 meters, accompanied by an access tunnel. The cavern extends for 650 meters, featuring a single platform as part of its design. Situated near the Teesta in the Kalimpong District of Bengal, this tunnel traverses through vulnerable and challenging geological and seismic conditions of the younger Himalayas. Like all other tunnels in the project, to counter vulnerability of the ground mass, latest and most sophisticated tunneling technology, i.e., New Austrian Tunneling Method (NATM) has been used here, the NFR sources added. The project is expected to be completed and made operational by 2027.

Sonmarg Terror Attack, Harsh Weather Push Zojila Tunnel Deadline To 2028
The Zojila Tunnel Project — set to be Asia's longest tunnel offering all-weather connectivity between Kashmir and Ladakh — was initially scheduled for completion by September 2026. The terror attack on a camp of labourers engaged in building a tunnel at Gagangir near Sonmarg in October 2024 was among the reasons cited by the Ministry of Road Transport and Highways for pushing the deadline of the Zojila Tunnel to February 2028. Union Minister Nitin Gadkari informed the Lok Sabha on Thursday that the Zojila Tunnel Project in Jammu & Kashmir — set to be Asia's longest tunnel offering all-weather connectivity between Kashmir and Ladakh — was initially scheduled for completion by September 2026. 'The project has been delayed due to multiple factors, including the impact of the Covid-19 pandemic, a terrorist attack at the Sonamarg Tunnel Project, and extreme adverse weather conditions," he said. The current physical progress of the project stands at 64 per cent, the Minister said, adding the project is 'now targeted for completion by February 2028". In August 2024, the Ministry had informed the Lok Sabha that over 52 per cent work on the Zojila road project had been completed, with a deadline of September 2026. On October 20, 2024, militants attacked a worker camp for the Z‑Morh tunnel project at Gagangir. Six migrant workers and a camp doctor were killed in the attack. The Z‑Morh Tunnel was inaugurated in January 2025 and renamed the Sonamarg Tunnel. 'Of these, 77 per cent are from the Union Territory of Jammu & Kashmir and 28 per cent of the overall workforce is from the Ganderbal District," he said. The project cost is estimated at Rs 6,809 crore, of which Rs 3,934.42 crore has been spent so far, Gadkari said. The tunnel coming up in Zojila is a 7.57 m high horseshoe-shaped single-tube, two-lane tunnel, which will pass under the Zojila Pass in the Himalayas between Ganderbal in Kashmir and Drass town in Kargil district of Ladakh. The project includes a Smart Tunnel (SCADA) system, which has been constructed using the New Austrian Tunneling Method. It is equipped with facilities like CCTV, radio control, uninterrupted power supply, and ventilation. view comments First Published: Disclaimer: Comments reflect users' views, not News18's.

Bullen train project gains momentum as first phase of 21 km long tunnel..., will pass through...
(File) New Delhi: There is more good news about the much-awaited Mumbai-Ahmedabad bullet train project. The ambitious mission has achieved its first important milestone as a 21-km-long tunnel between Mumbai's Bandra-Kurla Complex (BKC) and Thane's Shilphata has been constructed. Which method has been used? A 2.7-km-long continuous tunnel section has been successfully completed using the New Austrian Tunneling Method (NATM). The National High Speed Rail Corporation Limited (NSSRCL) has given this information. This achievement is a significant leap in India's first bullet train project, which aims to connect Mumbai and Ahmedabad through a high-speed rail corridor. This will significantly reduce travel time and increase transport efficiency between the two financial centers. The 21-km long tunnel will be a crucial part of the high-speed rail corridor, of which 16 km will be constructed using tunnel boring machines (TBMs) and the remaining five km using the New Austrian Tunnelling Method (NATM), including the section between Shilphata and Ghansoli. What else does the tunnel include? The tunnel also includes a seven-km undersea section under the Thane creek. To expedite the tunnelling work in the NATM section, an additional operated intermediate tunnel (ADIT) was constructed, enabling simultaneous excavation from both Ghansoli and Shilphata ends. Out of the total NATM section, about 1.62 km has been excavated from the Shilphata side and the total progress is 4.3 km. What is the cost of this project? The NHSRCL said that extensive safety measures have been implemented at the site, including installation of ground settlement markers, piezometers, inclinometers, strain gauges and biometric access control systems. These are designed to ensure safe and controlled tunnelling work without affecting nearby infrastructure or habitations. However, sources said that TBM machines have not yet been received from the companies for the construction of the 16-km-long tunnel, while the shafts and other equipment for these machines are in place. The total cost of the Mumbai-Ahmedabad High Speed Rail Corridor project has been estimated at Rs 1.08 lakh crore. As per the shareholding pattern, the central government will pay Rs 10,000 crore to NHSRCL, while Gujarat and Maharashtra have to pay Rs 5,000 crore each.
