With the commissioning of the Siemens Westrace MK-II interlocking system, Borivali now operates Mumbai’s largest and most advanced signalling setup.

Upgraded signalling room now resembles a modern mission-control centre, capable of handling dense train movements with greater speed, precision and safety. “The new system manages hundreds of routes, points and signals across multiple running lines, significantly improving operational reliability and safety,” a WR spokesperson said.
