The Kerala state government has constituted a high-level committee, led by the Chief Secretary, to examine and finalise the alignment for the proposed Thiruvananthapuram Metro Rail Project. The decision was made during a meeting chaired by Chief Minister Pinarayi Vijayan on 11 June, 2025.

The committee includes top officials from the revenue, finance, local self-government, and transport departments. It has been directed to study all facets of the Metro project and submit comprehensive recommendations to the government.

Three primary corridors are currently under consideration: Kazhakkoottam to Pappanamcode, Kazhakkoottam to Killipalam, and Palayam to Civil Station. The Kochi Metro Rail (KMRL), the special purpose vehicle (SPV) assigned to implement metro projects in the state, had earlier proposed six different alignment options for the conventional metro system.

The KMRL proposal includes both elevated and underground stretches. However, officials note that the underground segments would involve significantly higher costs for the state.

Originally proposed over a decade ago, the metro project saw little progress under successive administrations. The initial proposal from Delhi Metro Rail Corporation (DMRC) suggested a monorail, which was later replaced by a light metro plan. A revised Detailed Project Report (DPR) has since been submitted.
