The Mumbai-Ahmedabad Bullet Train project has marked significant progress with the commencement of track slab installation and Cement Asphalt Mortar (CAM) filling on the viaducts across multiple sites in Gujarat.
According to NHSRCL, the implementing agency for the high-speed rail corridor, around 160 km of track bed construction has been completed in the state.
Additionally, over 39,500 precast track slabs have been cast—covering nearly 197 track km in total.
A key milestone in the track installation phase has been the Flash Butt Welding (FBW) of 25-metre-long, 60 kg rails into 200-metre panels at various Track Construction Bases (TCBs).
With four Flash Butt Welding Machines currently operational, more than 1,543 such panels—translating to over 154 track km—have been welded so far.
NHSRCL said that the track installation process is mechanised with cutting edge machinery designed and manufactured in India
These Make in India fleet of track construction machinery includes:
Rail Feeder Cars (RFC): These carry 200-metre rail panels and lay temporary tracks on the reinforced concrete (RC) beds. Operating RFCs in Surat and Anand have already helped lay nearly 78 track km of temporary tracks.
Track Slab Laying Cars (SLC): Deployed in Bilimora and Vadodara, these machines can transport and place up to five precast slabs at a time onto the viaduct.
CAM Injection Cars: These machines, also stationed in Bilimora and Vadodara, mix and inject CAM under the slabs to maintain the precise alignment and elevation of the tracks.
