The electrification process for the Mumbai-Ahmedabad Bullet Train Corridor is underway, marking a significant milestone. The first steel masts for the overhead traction system have been installed between Surat and Bilimora. Meanwhile, a 210-meter bridge over NH-48 in Gujarat has been completed, advancing India’s high-speed rail infrastructure.
Electrification Work Begins on Mumbai-Ahmedabad Bullet Train Corridor:
The electrification work for the Mumbai-Ahmedabad Bullet Train corridor has commenced, with the first two steel masts installed at a height of 14 meters on the viaduct between Surat and Bilimora in Gujarat. This marks the beginning of installing over 20,000 masts, ranging from 9.5 to 14.5 meters in height, which will support the 2×25 kV Overhead Equipment (OHE) system for the high-speed rail network.
Aligning with the “Make in India” initiative, these OHE masts, manufactured domestically, conform to Japanese standards and specifications. The masts will play a pivotal role in supporting the overhead traction system, facilitating bullet train operations on the Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor.
210-Meter Bridge over NH-48 Completed:
Adding to the project’s achievements, a 210-meter-long Pre-Stressed Concrete (PSC) bridge was completed on January 9, 2025. The bridge spans the National Highway-48 near Dabhan village in Gujarat’s Kheda district, situated between Anand and Ahmedabad Bullet Train Stations.
Constructed using the Balanced Cantilever Method, the bridge comprises 72 precast segments with four spans of 40m + 65m + 65m + 40m. This construction method is ideal for longer spans, ensuring the bridge’s stability and efficiency.
Details of Completed Bridges on NH-48:
| Sr. No. | Length of the Bridge (in meters) | Span Configuration | Bullet Train Stations | District | Completed |
| 4th PSC Bridge | 210 | Four spans of configuration 40m + 65m + 65m + 40m | Between Anand & Ahmedabad | Kheda | 9th January 2025 |
| 3rd PSC Bridge | 210 | Four spans of configuration 40m + 65m + 65m + 40m | Between Vapi & Bilimora | Valsad | 2nd January 2025 |
| 2nd PSC Bridge | 210 | Four spans of configuration 40m + 65m + 65m + 40m | Between Surat & Bilimora | Navsari | 1st October 2024 |
| 1st PSC Bridge | 260 | Four spans of configuration 50m + 80m + 80m + 50m | Between Surat & Bilimora | Navsari | 18th August 2024 |
