Bullet train project: Railway Board directs NHSRCL to revise DPRs for new high-speed rail corridors


What Happened

  • The Railway Board has directed the National High Speed Rail Corporation Limited (NHSRCL) to revise Detailed Project Reports (DPRs) for new high-speed rail corridors beyond the Mumbai-Ahmedabad bullet train project.
  • Seven new corridors were announced in Budget 2026-27: Mumbai-Pune, Pune-Hyderabad, Hyderabad-Bengaluru, Hyderabad-Chennai, Chennai-Bengaluru, Delhi-Varanasi, and Varanasi-Siliguri.
  • NHSRCL has already submitted DPRs for six of the seven corridors (all except Varanasi-Siliguri) to the Railway Ministry.
  • The proposed corridors span approximately 4,000 kilometres with an estimated cost of around Rs 16 trillion.
  • The Mumbai-Ahmedabad corridor has achieved the milestone of 300 km of completed viaducts, with the first section (Surat-Bilimora, 51 km) expected to be operational in 2026.

Mumbai-Ahmedabad High-Speed Rail Corridor

The Mumbai-Ahmedabad bullet train project is India's first high-speed rail corridor, covering 508 km with a top speed of 320 km/h, reducing travel time from ~7 hours to ~2 hours. The project is being implemented by NHSRCL with Japanese Shinkansen technology (E5 series trains) and financial assistance from JICA (Japan International Cooperation Agency) — an 81% soft loan at 0.1% interest over 50 years with a 15-year moratorium. The project cost is approximately Rs 1.1 lakh crore. The corridor will have 12 stations, including an underground station at BKC, Mumbai.

  • Route: Mumbai (BKC) to Ahmedabad (Sabarmati), 508 km
  • Technology: Japanese Shinkansen (E5 series, manufactured by Kawasaki-Hitachi)
  • Maximum speed: 320 km/h; operating speed: 300-320 km/h
  • Stations: 12 (including underground BKC station)
  • Total cost: approximately Rs 1.1 lakh crore
  • JICA funding: 81% of project cost (0.1% interest, 50-year repayment, 15-year moratorium)
  • Viaducts completed: 300 km
  • First operational section: Surat-Bilimora (51 km), expected 2026

Connection to this news: The directive to revise DPRs for new corridors comes as the Mumbai-Ahmedabad project nears its first operational milestone, suggesting that the government is building on the experience and technology transfer from this pilot corridor to plan a nationwide high-speed rail network.

National High Speed Rail Corporation Limited (NHSRCL)

NHSRCL is a Special Purpose Vehicle (SPV) incorporated in 2016 as a joint venture between the Government of India and the governments of Gujarat and Maharashtra. It is responsible for the construction, operation, and maintenance of India's high-speed rail corridors. The corporation has conducted extensive surveys — including LiDAR aerial surveys, environmental impact assessments, social impact surveys, and alignment designs — for the proposed corridors spanning thousands of kilometres.

  • Incorporated: 2016 (SPV)
  • Shareholders: Government of India, Government of Gujarat, Government of Maharashtra
  • Mandate: construction, operation, and maintenance of high-speed rail corridors
  • Survey tools: LiDAR aerial surveys, EIA, social impact assessments
  • DPRs submitted: 6 of 7 new corridors
  • Technology base: Japanese Shinkansen (from Mumbai-Ahmedabad project)

Connection to this news: The Railway Board's direction to revise DPRs indicates that the initial reports need updates — possibly to incorporate learnings from the Mumbai-Ahmedabad construction, revised cost estimates, or changes in alignment to address land acquisition and environmental concerns.

Infrastructure Investment and Economic Multiplier Effects

High-speed rail projects generate significant economic multiplier effects through construction employment, real estate development around stations, supply chain linkages, and improved connectivity that reduces business travel costs. International experience from Japan's Shinkansen and China's high-speed rail network shows a GDP multiplier of 1.5-2.5x the investment value. However, India's high-speed rail projects face challenges including high per-km costs (approximately Rs 200-250 crore per km vs Rs 10-15 crore for conventional rail), land acquisition difficulties, and competition from low-cost air travel.

  • Per-km cost of high-speed rail: ~Rs 200-250 crore (vs Rs 10-15 crore for conventional)
  • Total proposed network: ~4,000 km across 7 new corridors
  • Estimated cost of 7 corridors: ~Rs 16 trillion
  • Economic multiplier (international benchmarks): 1.5-2.5x investment
  • Japan's Shinkansen network: ~3,000 km, operational since 1964
  • China's high-speed network: ~45,000 km (world's largest)

Connection to this news: The Rs 16 trillion investment across 4,000 km would be India's single largest infrastructure investment programme, requiring careful viability assessment given the high per-km costs and the need for sustained ridership to ensure financial sustainability.
