Abstract:  The Mumbai-Ahmedabad High-Speed Rail project represents a pioneering effort by the Ministry of Railways to introduce high-speed trains in India. Central to this monumental initiative is the construction of the underground station at Mumbai's Bandra Kurla Complex (BKC), a project marked by significant engineering and environmental challenges.

The excavation activities at BKC, located in the heart of the city, necessitate adherence to stringent…

High-speed rail’s (HSR) capacity to accelerate regional development is driven by the non-linear, dynamic, technical, and social interactions in an HSR system. To enable HSR project growth, policy makers must tackle complex issues, such as stakeholder engagement, safety, and cost and schedule overruns. A robust institutional framework that defines each stakeholder's role, the standards used, and coordination and conflict resolution mechanisms is…

Synopsys

This technical paper delves into a comparative analysis of steel bridge fabrication methods employed in Japan and traditional practices in India, with a specific focus on the Mumbai Ahmedabad High-Speed Rail (MAHSR) project's adaptation of Japanese techniques. Japan's cutting-edge approach to steel bridge construction, characterized by mechanization, precision, and stringent quality control, is examined in contrast to the conventional methods utilized in India.…

Abstract : India will soon have its first line with trains operating at internationally defined standards of high speed (exceeding 250 km/h). On the MAHSR (Mumbai-Ahmedabad High Speed Railway) corridor modern high speed trains will routinely operate at speeds as high as 200 mph (320 km/h). At high speed, trains are…

Abstract : Efficiency of high-speed rolling stock and its efficient operation is key to sustainability of any High-Speed Rail (HSR) project. Power/seat is an indicator of energy efficiency of high-speed rolling stock from design point of view. However, energy/seat-km is actual measure of energy efficiency of any high-speed rolling stock and is also referred as HSR efficiency. This paper looks into how the operational techniques combined…
