Overview
- Railways sanctioned DPR surveys for seven routes with 160 km/h potential: Shoranur–Mangalore (3rd & 4th line), Coimbatore–Shoranur (3rd & 4th), Shoranur–Ernakulam (3rd), Ernakulam–Kayamkulam via Kottayam (3rd), Kayamkulam–Thiruvananthapuram (3rd), Thiruvananthapuram–Nagercoil (3rd), and Turavur–Ambalappuzha (doubling).
- Railway Minister Ashwini Vaishnaw told the Rajya Sabha that KRDCL has been asked to revise the Silver Line DPR to integrate with Indian Railways standards, including broad gauge, Kavach, 2×25 kV electrification, flatter gradients, robust drainage, and environmental safeguards.
- The Kerala government is pressing to treat Silver Line as a standalone project rather than an integrated line, leaving the scheme in limbo pending revisions and clearances.
- Once DPRs are finalised, projects require stakeholder consultations and mandatory central appraisals such as by NITI Aayog and the Finance Ministry, with no fixed implementation timeline.
- Kerala’s cabinet granted in-principle approval last month for an RRTS on the Thiruvananthapuram–Kasaragod stretch, signalling a parallel pathway as K-Rail’s status remains unresolved.
