Bullet train hits triple century, construction of viaduct completed on 300 km corridor track, its top speed will be…,watch viral video
India’s first Bullet Train corridor between Mumbai and Ahmedabad has reached a significant construction milestone with the successful completion of 300 km of viaducts. According to the National High Speed Rail Corporation Limited (NHSRCL) statement, this achievement was marked by the launching of a 40 metre-long girder near Surat, Gujarat.
In a post on X(previously Twitter), Union Railway Minister Ashwini Vaishnaw shared the update on the successful completion of 300 km of viaducts. This milestone was achieved with the successful launch of a 40-meter-long full-span box girder near Surat in Gujarat.
The bullet train is likely to run at a maximum speed of 320 kilometers per hour, covering a total distance of 508 kilometers, with 351 kilometers in Gujarat and 157 kilometers in Maharashtra. Notably, 92% of the route (468 km) will be on elevated tracks.
“Out of 300 km of superstructure, 257.4 km is constructed through Full Span Launching Method (FSLM) including 14 river bridges, 37.8 km through Span by Span (SBS), 0.9 km steel bridges (10 spans ranging from 60 to 130 m in 7 bridges), 1.2 km PSC bridges (20 spans ranging from 40 to 80 m in 5 bridges) and 2.7 km in station building, ” National High Speed Rail Corporation Limited (NHSRCL) stated.
For constructing 257.4 km of viaduct through FSLM and 37.8 km of viaduct through SBS, 6455 & 925 spans of 40 m each, respectively, were used. According to the news agency ANI report, the project has supported the use of indigenously designed and manufactured equipment such as Straddle Carriers, Launching Gantries, Bridge Gantries, and Girder Transporters for construction. This marks a first for Indian infrastructure, showcasing India’s growing capabilities in high-speed rail technology with the support of the Japanese government.
The adoption of the Full Span Launching Method has significantly accelerated construction, as full-span girder erection is up to ten (10) times faster than conventional segmental methods. Each full-span box girder weighs 970 metric tons. Segmental girders are used selectively in locations where full-span installation is not feasible.
A total of 27 dedicated casting yards were established along the corridor to facilitate construction. Steel bridges are fabricated in seven workshops spread all across the country, three in Gujarat, one each in Uttar Pradesh, Tamil Nadu, Maharashtra, and West Bengal truly exemplifying the spirit of unity of our country.
As per the ANI report, more than 3 lakh noise barriers have been installed along the viaducts to mitigate noise during operations. In addition to the viaducts, the project has also completed 383 km of pier work, 401 km of foundation work and 326 km of girder casting.
The thematic Bullet Train stations are rapidly taking shape. These stations will be integrated with the rail and road based transport system to provide seamless travel to passengers. The stations will be equipped with state-of-the-art passenger amenities. Track works over viaducts have also started, and around 157 track km of RC track bed construction has been achieved so far in Gujarat. The rolling stock depots with modern infrastructure are also getting ready in Maharashtra and Gujarat.

According to the official website of National High Speed Rail Corporation Limited (NHSRCL), after starting from Bandra Kurla Complex (BKC) area in Maharashtra, the high-speed train running at a speed of 320 km/h will revolutionise intercity travel in the region and will integrate the economies of Mumbai, Vapi, Surat, Anand, Vadodara & Ahmedabad. It will have stops at 10 cities in between namely Thane, Virar, Boisar, Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand, Ahmedabad and will terminate at Sabarmati.
The entire journey will be completed in about 2 hours 7 minutes with limited stops (at Surat, Vadodara and Ahmedabad), which is substantially less than the time taken by conventional trains or road journeys.
