Mechanised track installation with cutting-edge machinery for bullet train corridor

The Mumbai-Ahmedabad bullet train project will have J-Slab track system based on the Japanese Shinkansen track system, according to an NHSRCL press release. This is for the first time, the J-Slab ballastless track system is being used in India.

For 352 km of alignment in Gujarat & DNH, 704 km of track is to be laid on viaduct and two bullet train depots at Sabarmati and Surat. The entire process of track installation is mechanised with cutting edge machinery especially designed and manufactured as per Japanese specifications. Taking the initiative under Make-in-India policy, some of the machines are now being manufactured in India also.

The track laying work in Gujarat is progressing well as more than 35,000 MT of rails and three sets of track construction machinery have been received at Surat and Vadodara for the project, according to NHSRCL.

“The fleet of machines include rail feeder car, track slab laying car, CAM laying car and flash butt welding machine, which will be used for track construction works. The assembly, testing and commissioning of these machines is in progress,” the press release said.
