Thiruvananthapuram: After more than a decade of planning and repeated delays, the proposed Thiruvananthapuram Metro Rail project is set to cross a key milestone. The Delhi Metro Rail Corporation (DMRC) is expected to submit the revised Detailed Project Report (DPR) to Kochi Metro Rail Ltd (KMRL) within two weeks.
Revised DPR Aligned with PM Gati Shakti
KMRL Managing Director Loknath Behera stated that the DPR was revised after the Union government directed the implementing agency to align the project with the PM Gati Shakti National Master Plan. This ensures seamless integration with other transport infrastructure. Behera told TOI, "DMRC will submit the revised DPR to KMRL within two weeks. Once we receive it, KMRL will examine the report, which will take around 15 days. If there are no major issues, it will be forwarded to the state government for approval before being sent to the Centre for final sanction."
Background and Delays
The DPR was originally scheduled for submission in March this year. However, the process was delayed by the assembly election model code of conduct and subsequent revisions required under the PM Gati Shakti framework. DMRC has already completed the field survey for the project.
Phase-I Alignment Finalised
The revised DPR finalises the Phase-I alignment from Pappanamcode to Kazhakootam via Thampanoor, MG Road, Kesavadasapuram and Government Medical College. The alignment received in-principle approval from the previous LDF government in November last year after months of technical evaluation and consultations among multiple agencies.
Key Connectivity and Benefits
The proposed corridor is designed to connect some of the city’s busiest residential, commercial and institutional centres, including Thampanoor railway station, the central bus terminal, the Secretariat, Medical College, Technopark and Kazhakkoottam. The Metro is expected to ease congestion along the capital’s heavily trafficked north-south corridor while providing a sustainable public transport alternative.
According to sources, the metro yard is proposed on Kerala University land at Kazhakootam.
Modifications and Future Steps
The project has undergone several modifications over the past year. Following approval of the alignment, KMRL asked DMRC to revise the DPR to incorporate the new route. The report was also updated to improve multimodal connectivity, reduce land acquisition requirements, and enhance projected ridership. The DPR is expected to finalise the extent of elevated and underground stretches.
Budgetary Allocations
Officials said the upcoming state Budget is unlikely to earmark funds specifically for the project, despite the ruling UDF reiterating its commitment to metro rail systems in Thiruvananthapuram and Kozhikode in its election manifesto. Budgetary allocations are expected only after the project secures the required approvals from the Centre.
