Indian construction giants Larson and Tubo (L&T) recently won a major contract worth 44.7 billion rupees (approximately 510 million US dollars) to lay 157 kilometers of track on the Mumbai Ahmedabad high-speed railway line, adding crucial support to the highly anticipated high-speed rail construction.

The contract was approved on September 11, covering a wide range of works, including not only the installation of Flat noodles track between Bangelakula Complex (BKC) in Mumbai and Zaralli on the Maharashtra Gujarat border, but also the track works of four stations, as well as the construction of viaducts, bridges, tunnels and Tane depot. L&T will adopt the J-Slab system based on Japanese Shinkansen technology, which is designed for high-speed operation at 320 kilometers per hour and can effectively reduce maintenance costs throughout the entire lifecycle. The National High Speed Rail Corporation (NHSRCL) has successfully applied this technology to other sections of the new line in Gujarat.

The BKC Zaroli track project is of great significance, as it will be deeply integrated with the already launched civil engineering and system contract projects, involving the construction of stations, overpasses, as well as the installation of power supply and signal systems. It is one of the most complex parts of this high-speed line. As Mamata Shah, Managing Director of Delhi based consulting firm Urban Infrastructure, stated, this contract is a key milestone that connects the city's core areas, high-density regions, and future economic centers.

At present, the construction of the Mumbai Ahmedabad high-speed line is steadily advancing. The 320 kilometer aerial viaduct and 17 river bridges have been completed, and the 21 kilometer tunnel between BKC and Hilpata continues to be constructed. Seven mountain tunnels in the Pagar area of Maharashtra are also being excavated, and 1800 overhead contact line pillars cover the main line of the 44 kilometer aerial viaduct.

In addition, NHSRCL has partnered with Jarts, a Japanese railway technology service company, to conduct comprehensive training and certification programs for Indian engineers, in order to reserve professional talents for high-speed rail construction. Editor/Cheng Liting
