Railway Minister reveals video of ballastless track for bullet train: 'First time In India'

PTC News Desk: Railway Minister Ashwini Vaishnaw showcased India's pioneering ballastless track system designed for the high-speed bullet train project connecting Mumbai and Ahmedabad. This marks the debut of the J-slab ballastless track system in India, emphasizing the country's technological advancement in railway infrastructure.

Vaishnaw, sharing the milestone on social media platform X, unveiled the video detailing the progress achieved for the Bullet Train project, which aims to breach the 320 kmph speed barrier. He highlighted that 295.5 km of piers and 153 km of viaducts have already been completed, signaling significant strides in the project's execution.


The ballastless track, also known as 'slab track,' is gaining traction worldwide for high-speed railway lines due to its structural integrity and reduced maintenance requirements. In a first for India, the innovative J-slab track system features pre-cast track slabs meticulously outfitted with fastening devices and rails.

This track system is supported by a reinforced concrete (RC) track bed with a thickness of approximately 300mm, constructed on-site for individual up and down track lines on the viaduct top. With a width of 2420mm, the RC track bed ensures stability, as stated by the National High-Speed Rail Corporation Ltd (NHSRCL).
