Mumbai-Ahmedabad bullet train project completes portal beam work over Delhi-Mumbai Rajdhani line in Vadodara

Key facts

• The Mumbai-Ahmedabad High-Speed Rail (MAHSR) project has completed all 14 portal beams over the Delhi-Mumbai Rajdhani railway line in Vadodara, Gujarat, marking a major construction milestone for India's first bullet train project.
• The Vadodara stretch of the project is approximately 8.3 km long and crosses five Indian Railways lines, including two main lines, passing diagonally over the Delhi-Mumbai Rajdhani route.
• Each portal beam was built using the cast-in-situ method, weighs about 1,500 tonnes, and measures around 4 metres in height, 4 metres in width and 37 metres in length, requiring about 590 cubic metres of concrete and a 55-tonne reinforcement steel cage.
• With the portal beams completed, the next construction stage involves launching 40-metre-long composite girders to extend the elevated viaduct along the bullet train alignment.
