Bengaluru’s Yellow Line Launch Held Up by Safety Certificate Delay and Train Shortfall

Certification glitches in signalling data have held up the Independent Safety Assessment, preventing the line from proceeding to the CMRS inspection.

Overview

  • An Italian government–run firm collaborating with Siemens India and Siemens AG has delayed the Independent Safety Assessment due to technical glitches in signalling datasets.
  • The Commissioner of Metro Railway Safety inspection cannot be scheduled until the ISA certificate arrives, and its three-day audit plus one-week report could further extend timelines.
  • With only three trainsets delivered, service intervals would stretch to 20–25 minutes, falling short of feasible headways for regular operations.
  • BMRCL has partnered with ACES India on a 13-year deal to install metro-wide mobile connectivity and is adopting an Art & Science theme proposed by Kiran Mazumdar-Shaw at Hebbagodi station.
  • Citizen groups and commuters held protests at Lalbagh and corporate leaders have inspected stations to press for the line’s August 15 launch.
