Mumbai Ahmedabad High-Speed Rail (MAHSR) Corridor Bridge Articulation and Force Transfer System

By Shri D. P. Singh,  GM, NHSRCL
Shri Sanjeev Kumar,  JGM, NHSRCL
Shri Manoj K. Choudary Nalla,  DGM, NHSRCL
Shri Rahul Kalra,  Senior Manager, NHSRCL

Abstract : Viaducts and Bridges play a pivotal role in transportation infrastructure, serving as critical links between regions and accommodating various modes of transportation, including High-Speed rail (HSR), Railways, Metros, and Highways. The design and construction of bridges for HSR projects differ significantly…

Review of research on environmental noise standards / policies / guidelines and measurement methodology in high-speed rail

By Shri Sandeep Srivastava, Director (Rolling Stock), NHSRCL
Shri Govindu Sivasankar, DGM (Rolling Stock), NHSRCL
Shri Gautam Dua, DGM (Rolling Stock), NHSRCL

Abstract : Noise generated by rolling stock in High-Speed Rail (HSR) is of paramount importance from environment point of view. A lot of developments and improvements have happened in rolling stock design to reduce noise during running. There exists different standards and methodology for measurement of noise emanating…

Determinants of the Selection of High-Speed Rolling Stock for Safe and Sustainable Operations

By Shri Sandeep Srivastava, Director (Rolling Stock), NHSRCL

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…

Forging the Future of Bridge Fabrication: A Comparative Analysis of Japanese and Indian Fabrication Techniques with the backdrop of MAHSR Project

-Rajneesh Saroj, Dy. CPM/NHSRCL

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. The…

A review of research into aerodynamic concepts for high speed trains in tunnels and open air and the air-tightness requirements for passenger comfort

By Shri Sandeep Srivastava, Director (Rolling Stock), NHSRCL
Shri Govindu Sivasankar, DGM (Rolling Stock), NHSRCL
Shri Gautam Dua, DGM (Rolling Stock), NHSRCL

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…

Energy Efficient Operation of Rolling Stock in HSR

By Shri Sandeep Srivastava, Executive Director (Rolling Stock), NHSRCL     

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…
