T’PURAM/KOCHI: With the deadline for the social impact assessment (SIA) for the SilverLine semi high-speed rail project getting over about two weeks ago, the project is now in limbo. Six months after it was initiated, the SIA was completed only in around 45 of the total 190 villages across the state. Meanwhile, the Kerala High Court on Tuesday directed K-Rail to respond to the statement filed by the Railway Board saying it had neither approved nor concurred with the assessment.
