The seven proposed corridors, spanning nearly 4,000 kilometres, are estimated to cost around ₹16 trillion. These include:
- Mumbai–Pune
- Pune–Hyderabad
- Hyderabad–Bengaluru
- Hyderabad–Chennai
- Chennai–Bengaluru
- Delhi–Varanasi
- Varanasi–Siliguri
These corridors aim to strengthen connectivity between major economic and urban hubs.
Steps Initiated by Railways
The Railway Board has outlined several key action points:
- Updating Detailed Project Reports (DPRs) with revised cost estimates
- Conducting financial viability assessments
- Standardising high-speed rail systems nationwide
- Creating dedicated field-based core teams
Initiating pre-construction activities and contract documentation
The focus is on ensuring faster implementation compared to the first corridor currently under construction — the Mumbai–Ahmedabad High-Speed Rail Corridor.
Emphasis on Indigenisation
Railway Minister Ashwini Vaishnaw has stated that future corridors will witness higher levels of indigenisation. India has gained valuable experience from the Mumbai–Ahmedabad project, especially in:
- Civil engineering works
- Overhead equipment systems
- Signalling technology
- Rolling stock
- Station construction
This learning curve is expected to reduce delays and enhance efficiency in upcoming projects.
Strategic Significance
The expansion of bullet train corridors will:
- Reduce travel time significantly
- Promote regional economic integration
- Generate employment
- Enhance technological capability in rail infrastructure
- Support the Make in India initiative
By scaling up high-speed rail infrastructure, India aims to modernise its transport ecosystem and align with global standards in railway technology.
