Context:
India plans to build seven new high-speed rail corridors spanning about 4,000 km with an investment of ₹16 lakh crore, aiming to achieve 100% self-reliance (Atmanirbhar Bharat) in bullet train technology and manufacturing.
Key Highlights:
- New High-Speed Rail Corridors
- Proposed corridors include:
- Mumbai–Pune
- Pune–Hyderabad
- Hyderabad–Bengaluru
- Hyderabad–Chennai
- Chennai–Bengaluru
- Delhi–Varanasi
- Varanasi–Siliguri
- Infrastructure Vision
- Total planned network length: ~4,000 km.
- Estimated investment: ₹16 lakh crore.
- Atmanirbhar Technology Push
- Indigenous technologies will be used in:
- Track construction
- Viaducts, pillars, and foundations
- Overhead electrical systems
- Advanced signaling and stations
- Train design and manufacturing
- Existing Bullet Train Project
- Mumbai–Ahmedabad High-Speed Rail corridor under construction with Japanese Shinkansen technology collaboration.
- Connectivity and Economic Development
- Corridors connect major economic hubs such as Hyderabad, Bengaluru, and Chennai, forming a “high-speed diamond” economic region.
- Implementation Challenges
- Land acquisition delays
- Engineering complexities
- Past disruptions due to COVID-19 pandemic
- Complementary Infrastructure
- East–West Dedicated Freight Corridor will connect industrial regions in Maharashtra, Madhya Pradesh, Chhattisgarh, and Odisha to ports like Paradip and Vadhvan.
