Bullet Train Girder Launched In Maharashtra: NHSRCL

Meanwhile, the National High-Speed Rail Corporation Limited said the first 40-metre full span pre-stressed concrete box girder for the Mumbai Ahmedabad bullet train corridor has been successfully launched in Maharashtra.

The girder, at 970 metric tonnes, is the heaviest ever used in the country's construction sector, a NHSRCL release said. "The launch of the girder took place at Sakhare village in Dahanu. It is cast as a single, monolithic unit, free of construction joints, using 390 cubic meters of concrete and 42 metric tonnes of steel. The use of full-span girders allows construction to progress up to 10 times faster compared to conventional segmental methods," it added.

To support rapid construction, NHSRCL is deploying specialized indigenous heavy machinery such as straddle carriers, bridge launching gantries as well as girder transporters, it added.

Siemens Consortium Gets Advanced Signalling, Telecom System Contract

In another development, the authorities awarded a contract to a consortium led by Dineshchandra R Agrawal (DRA) Infracon Private Limited, Siemens Limited and Siemens Mobility GmbH to install advanced signalling and telecommunication system for the Mumbai-Ahmedabad bullet train project.

The NHSRCL is the implementing agency for the country's first high-speed rail project. "The order valued at approximately Rs. 4,100 crores, includes Siemens Limited's share of Rs. 1,230 crore for the design, installation, and long-term maintenance of advanced signaling and telecommunications technologies," a press note from Siemens Limited said.

It added, "The project is expected to be executed over a period of 54 months, with Siemens providing 15 years of maintenance services, ensuring lifecycle reliability."

The company stated that as part of the contract, it will implement European Train Control System (ETCS) Level 2-based signalling and train control technologies, which are designed to support train operations at speeds up to 350 km/h, enable real-time train supervision, allow continuous wireless communication and centralise traffic management.

"As a consortium, we are proud to partner with National High Speed Rail Corporation Limited, in the prestigious high-speed rail project. This project reflects our commitment to 'Make in India' and delivering technologies that promote sustainable and future-ready mobility," Sunil Mathur, managing director and chief executive officer, Siemens Limited, said.
