Why the Kerala government scrapped the Rs 64,000 crore SilverLine project

📌 Summary:

• The Congress-led United Democratic Front (UDF) cabinet decided to denotify SilverLine, the Rs 64,000-crore semi-high-speed rail project mooted by the previous Left (LDF) government; CM V D Satheesan said the government is not opposed to high-speed rail but called this project "an environmental disaster and financially unviable".

• About the project: SilverLine was a 530-km standard-gauge line between Thiruvananthapuram and Kasaragod, designed to cut travel time from 12 hours to four, with trains running at up to 200 km/h, nine-car rakes carrying 675 passengers, and 11 stations.

• It was to be executed by Kerala Rail Development Corporation (K-Rail), a 51:49 joint venture between the Kerala government and Indian Railways; the state cabinet sanctioned it in 2021 with a token allocation of Rs 2,000 crore from the Kerala Infrastructure Investment Fund Board.

• Why it was opposed: about 1,383 hectares were to be acquired (1,198 hectares from private parties), triggering widespread protests over displacement; activists warned the alignment would cut through wetlands, paddy fields and ecologically sensitive zones, while critics flagged financial losses.

• The Railways withheld sanction, questioning the project's viability in Kerala — where six-lane National Highway development is already underway — and holding that it would affect the expansion of existing railway tracks; the social impact assessment for land acquisition was subsequently suspended.

• The way forward: with SilverLine in limbo, the LDF government in January 2026 gave in-principle approval for a Regional Rapid Transit System (RRTS), modelled on the Delhi-Meerut RRTS, as an alternative for Kerala.
