The Good News for Ahmedabad-Mumbai Bullet Train Project: The first major substation in Gujarat has reached another important milestone, with the first major traction substation in Bilimora, Navsari district, nearing completion. The development marks significant progress in building the electricity infrastructure required to operate India’s first high-speed rail corridor.
The substation is being developed over approximately 18,000 square metres. Most of its major construction work has been completed, while equipment installation, testing and commissioning activities are progressing.
The development is particularly important for Gujarat, as the bullet train corridor will connect major cities including Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand and Ahmedabad.
Bilimora Gets Gujarat’s First Major Bullet Train Traction Substation
According to a report published by Sandesh, the traction substation at Bilimora has reached the final stages of construction. Several important infrastructure components have already been completed, including buildings for control panels, changeover switches, transformers and circuit breakers. Construction of the gantry towers and beams has also been completed.
The remaining work includes installing and testing equipment and preparing the facility for commissioning. Once operational, the substation will help supply electricity to the overhead power system used by bullet trains.
14 Traction Substations Planned Across Gujarat and Maharashtra
The Mumbai–Ahmedabad High-Speed Rail project requires a reliable electricity supply across its entire route. For this purpose, a total of 14 traction substations are being developed.
These include:
| State | Planned traction substations |
|---|---|
| Gujarat | 9 |
| Maharashtra | 5 |
| Total | 14 |
Proposed traction substation locations in Gujarat
The nine planned locations in Gujarat include:
- Vapi
- Bilimora
- Surat
- Bharuch
- Vadodara
- Anand
- Mehmadabad
- Ahmedabad
- Sabarmati Depot
Proposed locations in Maharashtra
The five locations reported for Maharashtra include:
- Mumbai
- Thane
- Virar
- Boisar
- Thane Depot
These substations are intended to provide a continuous and reliable electricity supply for high-speed train operations.
How Will the Ahmedabad-Mumbai Bullet Train Get Electricity?
The Gujarat section of the project will receive electricity from GETCO’s 220 kV Ambetha Grid Substation. The electricity will be transferred to the traction substations, where it will be converted to the required voltage level before being supplied to the railway’s overhead equipment.
The project uses a 2×25 kV traction power supply system.
In simple terms, the process works as follows:
- Electricity is received from the power grid.
- The traction substation manages and converts the electricity to the required supply arrangement.
- Power is transmitted through the overhead equipment installed above the railway tracks.
- The pantograph mounted on top of the bullet train collects electricity from the overhead wires.
- The electrical system powers the train during its journey.
This system is designed to support the high and consistent power requirements of high-speed rail operations.
Central Control Centre to Monitor Electricity Supply
The traction power supply network will be monitored through a central control centre. The system will allow authorities to monitor electricity supply conditions in real time across the corridor. It will also help identify technical problems and coordinate the necessary response. Reliable power management is essential for high-speed trains, which require a stable electricity supply throughout their journey.
What Does This Development Mean for Surat and Other Gujarat Cities?
The Ahmedabad-Mumbai Bullet Train corridor will pass through several important cities in Gujarat, including Vapi, Bilimora, Surat, Bharuch, Vadodara, Anand and Ahmedabad. The planned traction substations at different locations will form an important part of the electricity infrastructure supporting the corridor.
For Surat, the project is significant because the city is among the major destinations on the proposed high-speed rail route. The development of supporting infrastructure in Gujarat represents progress towards establishing the complete operating system required for bullet train services.
However, the completion of the Bilimora substation alone does not indicate that train services will begin immediately. Other construction, systems integration, testing and operational approvals are also required.

Frequently Asked Questions
1. Where is the first major bullet train traction substation in Gujarat being built?
It is being developed in Bilimora, in Navsari district of Gujarat.
2. How large is the Bilimora traction substation?
The substation covers approximately 18,000 square metres.
3. How many traction substations are planned for the Mumbai–Ahmedabad Bullet Train project?
A total of 14 traction substations are planned, including nine in Gujarat and five in Maharashtra.
4. Will Surat have a bullet train traction substation?
Yes. Surat is among the nine proposed locations for traction substations in Gujarat.
5. Where will the bullet train get electricity in Gujarat?
The reported arrangement uses electricity from GETCO’s 220 kV Ambetha Grid Substation, which will be supplied through traction substations to the railway’s overhead power system.
6. Does the completion of the Bilimora substation mean bullet train services will start soon?
Not necessarily. The substation is one part of the larger project. Other infrastructure, testing, systems integration and operational preparations are also necessary before passenger services can begin.
Conclusion
The progress of the Bilimora traction substation is an important development for the Ahmedabad-Mumbai Bullet Train project. With major construction work completed and equipment installation and testing underway, Gujarat is moving ahead with the electricity infrastructure needed for high-speed rail operations.
For Surat, Ahmedabad and other cities along the corridor, the development represents another step towards the country’s first bullet train network.
