Overview
- The Commissioner of Railway Safety cleared the 3.21 km section on January 18 after inspections and speed trials, authorising 70 kmph on the new 5th line, 80 kmph on the 6th line, 15 kmph on loop lines, and a 23-tonne axle-load limit.
- Commissioning completes Phase I of the Mumbai Central–Borivali 6th Line project from Bandra Terminus to Borivali, delivered in a planned 30‑day window with night blocks and major bridge re‑girdering.
- Borivali now operates on a new Siemens Westrace MK‑II electronic interlocking, replacing relay-based signalling to manage complex suburban and long‑distance movements.
- Trial operations began January 19, but suspension of entry and exit at Kandivali car shed and speed curbs between Kandivali and Malad led to 102 cancellations on January 20, with Western Railway announcing another 102 for January 21.
- Officials say the added line will segregate suburban and long‑distance trains to improve punctuality, and media reports cite proposed new local services and train shifts pending timetable approvals.
