Mumbai-Ahmedabad Bullet Train BIG Update, 160 Km of track bed completed in Gujarat, operations likely to begin by…, top speed to be…
New Delhi: The Indian Railways has made a significant progress on the Mumbai-Ahmedabad Bullet Train project with the start of track slab installation and Cement Asphalt Mortar (CAM) filling on viaducts at multiple locations in Gujarat. As per the NHSRCL, the implementing agency for the high-speed rail corridor, around 160 km of track bed construction has been completed in the state. It is important to note that 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). Currently, there are four Flash Butt Welding Machines which are operational, and more than 1,543 such panels—translating to over 154 track km—have been welded so far. NHSRCL has said that the track installation process is mechanised with cutting edge machinery designed and manufactured in India Notably, the entire track laying process is being carried out using high-end, indigenous machinery under the 'Make in India' initiative. Here are some of the key details: Rail Feeder Cars (RFC) carry 200-metre rail panels and lay temporary tracks on the reinforced concrete (RC) beds. The RFCs were earlier operated in Surat and Anand. The RFC helped lay nearly 78 track km of temporary tracks. Track Slab Laying Cars (SLC) was Deployed in Bilimora and Vadodara. These machines have the capacity to transport and place up to five precast slabs at a time onto the viaduct. CAM Injection Cars, stationed in Bilimora and Vadodara, mix and inject CAM under the slabs to maintain the precise alignment and elevation of the tracks. India's first high-speed bullet train corridor connecting Mumbai and Ahmedabad is rapidly transforming from blueprint to reality, with trial runs scheduled on the Sabarmati–Vapi stretch by 2028 and full operations across the 508-km corridor expected by 2030. Mumbai-Ahmedabad Bullet Train project: All You Need To Know The Mumbai–Ahmedabad corridor spans 348 kilometres in Gujarat and 156 kilometres in Maharashtra The officials have strategically placed stations in key growth centres including Mumbai, Thane, Boisar, Vapi, Surat, Vadodara and Ahmedabad. Among these, Surat is set to host India's first operational bullet train station, which is now nearing completion. Union Minister Harsh Sanghvi recently confirmed that the station is on track to begin trial runs next year, with full-scale operations expected by 2029. Designed with Japanese assistance, the bullet train system incorporates noise-reducing infrastructure—over three lakh sound barriers have already been installed. Thematic stations are being designed to integrate seamlessly with local road and rail systems, strengthening regional connectivity and providing future-ready transport nodes.

Track laying work on 197-km stretch of bullet train corridor full swing in Gujarat
With a December 2025 deadline set for the first trial run of a section of the Mumbai-Ahmedabad High Speed Rail bullet train in Gujarat, the track laying work on the train corridor is in full swing. The National High Speed Rail Corporation Limited (NHSRCL) on Tuesday said that track work on nearly 197 kilometre stretch of the Gujarat portion has gained momentum. In a statement on Tuesday, NHSRCL said that the installation of track slab and CAM (Cement Asphalt Mortar) filling have commenced in on the viaduct in Gujarat at different locations, which includes the completion of around 160 kilometres of track bed construction and around 39,500 track slabs cast — equivalent to nearly 197 kilometres of track on the 508 kilometre stretch of the corridor. The NHSRCL said that Flash Butt Welding machine (FBWM) has been used to weld the 25-m long 60 kg rails to form 200-m long panels at the track construction base (TCB) over the viaduct. 'At present, four FBWM are functioning. More than 1543 rail panels (200 m long) have been welded i.e. more than 154 track km of rails… The track installation process is mechanized with cutting edge machinery designed and manufactured in India,' NHSRCL said. 'The Make in India fleet of track construction machinery includes Rail Feeder Car (RFC), track slab laying car and Cement Asphalt Mortar Injection Car,' NHSRCL added. The Rail Feeder Car (RFC) has helped lay 78 kilometres of the track in the Surat and Anand sections by pushing the 200-m long panels over Reinforced Concrete (RC) to lay the temporary track. The Track Slab Laying Car (SLC) — working in the Vadodara and Bilimora section — has been deployed to lay the precast track slabs on the RC track bed. 'After placement of the track slabs on the RC bed, CAM car runs on the other track (i.e. on both UP and DN line temporary track at standard gauge is to be laid). This CAM car mixes the CAM ingredients in designed proportion and thereafter, CAM mix is injected under the slab (in special bags) to maintain the required line and level of the final track. At present, one CAM car each at Bilimora and Vadodara district are functioning,' NHSRCL said.
