The National High Speed Rail Corporation Limited (NHSRCL) has officially initiated pre-construction activities and Detailed Project Report (DPR) updates for the high-speed rail network connecting major South Indian economic hubs. However, the ambitious expansion plan has sparked widespread concern in Kerala, as the state finds itself entirely excluded from the Union Government’s high-speed rail blueprint.
The Ministry of Railways is moving forward with three key bullet train corridors forming a “South High-Speed Triangle”:
- Chennai – Bengaluru High-Speed Rail: Covering 306 km with an operating speed of 320 km/h, reducing travel time to just 1 hour and 13 minutes.
- Bengaluru – Hyderabad High-Speed Rail: Cutting transit time down to approximately 2 hours.
- Chennai – Hyderabad High-Speed Rail: Connecting the eastern coast and Telangana via Amaravati in 2 hours and 55 minutes.
Kerala’s Pioneer Efforts Ignored Despite High Demand
Ironically, Kerala was among the first Indian states to propose an independent high-speed rail corridor (formerly SilverLine / K-Rail) long before neighboring states began drafting bullet train plans. Furthermore, Indian Railways’ official patronage data consistently demonstrates that Kerala operates the most profitable and heavily occupied Vande Bharat Express routes in the entire country, underscoring massive public demand for rapid intercity transit.
Despite this proven economic viability, the Centre has turned down Kerala’s proposals for dedicated high-speed tracks. A major point of contention remains track gauge selection: while NHSRCL mandates 1,435 mm Standard Gauge for all 320 km/h bullet train corridors nationwide, Kerala advocated for a Broad Gauge high-speed system to maintain interoperability with existing Indian Railways lines.
Centre’s Alternative 160 km/h Proposal Faces Delays
In place of a true bullet train network, Central officials have suggested that upgrading Kerala’s rail corridor with 3rd and 4th Broad Gauge tracks capable of supporting speeds up to 160 km/h would be sufficient to meet the state’s transportation needs.
However, progress on these conventional track expansion projects remains sluggish:
- Lack of Dedicated Survey Infrastructure: Survey operations across five designated rail sections suffer from severe manpower shortages and the absence of dedicated project offices.
- Ernakulam – Shoranur 3rd Line: Although announced first among the five survey sections, execution on the ground has faced continuous administrative bottlenecks.
- DPR Pending Since 2018: Feasibility studies and preliminary survey work initiated as early as 2018 have failed to materialize into an approved Detailed Project Report (DPR).
Growing Infrastructure Deficit in the Region
Commuter rights organizations and infrastructure experts warn that excluding Kerala from the broader South Indian bullet train network risks isolating the state from rapid regional economic integration. As tech hubs like Bengaluru, Chennai, and Hyderabad tighten their commercial links through high-speed mobility, Kerala’s reliance on congested two-track broad-gauge lines could exacerbate transit delays for years to come.
State administrative leaders are expected to press the Union Ministry of Railways for a fresh review of Kerala’s high-speed rail alignment or an expedited approval of the long-pending 3rd and 4th track quadrupling projects.
Which South Indian cities are being connected by bullet train corridors?
The Union Government is developing three high-speed rail corridors connecting Chennai, Bengaluru, and Hyderabad.
Why was Kerala excluded from the South Indian bullet train network?
The Ministry of Railways favors standard gauge for 320 km/h bullet trains, whereas Kerala proposed broad gauge high-speed tracks, leading the Centre to suggest 160 km/h 3rd and 4th line capacity expansion instead.
What is the travel time on the upcoming Chennai-Bengaluru bullet train?
The 306 km Chennai-Bengaluru high-speed rail will cover the distance in 1 hour and 13 minutes at an operating speed of 320 km/h.
What is the status of the 3rd and 4th line upgrades in Kerala?
Survey work for 3rd and 4th tracks (such as Ernakulam-Shoranur) has experienced delays since 2018 due to staff shortages and lack of a finalized DPR.
