The Kerala Cabinet has given in-principle approval for a 583-kilometre Regional Rapid Transit System (RRTS) corridor that will stretch from Thiruvananthapuram in the south to Kasaragod in the north, marking a major shift in the state’s transport strategy and a renewed effort to establish high-speed connectivity along the length of Kerala.
This decision, taken at a recent Cabinet meeting chaired by Chief Minister Pinarayi Vijayan, comes after the earlier SilverLine semi-high-speed rail project — previously envisioned as the state’s flagship rail modernisation plan — failed to secure technical clearance and faced resistance on environmental and land acquisition grounds.
Under the approved RRTS proposal, Kerala will now formally communicate its interest to the Central government, triggering consultations between the state Transport Department and Union officials. Once the Centre grants its own in-principle approval, the two governments are expected to sign a memorandum of understanding (MoU). After that, the state will prepare and present detailed technical and financial plans to the Cabinet for final sanction.
The RRTS model – patterned on the successful Delhi–Meerut corridor – is designed as an elevated, high-speed rail system capable of operating at speeds between 160 and 180 km/h with closely spaced stations that serve both long and short-distance commuters. The elevated design is also aimed at reducing large-scale land acquisition and safeguarding ecologically sensitive zones — a major concern in Kerala’s densely populated and environmentally fragile terrain.
Implementation is planned in four phases, with the first stretch (the Travancore Line from Thiruvananthapuram to Thrissur) estimated for completion between 2027 and 2033. Integration with existing and proposed metro systems in Kochi, Thiruvananthapuram and Kozhikode is also part of the vision, potentially transforming Kerala’s regional and urban mobility landscape.
