Monorail’s indigenous signalling system gets independent safety assessor certification

A total of 10 new rakes from Medha have been being delivered incrementally for over a year. The old rakes will be integrated with the new signalling system.

FIVE MONTHS after it stopped operations, the indigenously-made Communications-Based Train Control (CBTC) signalling system and new rolling stock for the Mumbai monorail has got certification from an Independent Safety Assessor (ISA). This makes it for the first time that an Indian-make CBTC system will run in the country.

Bureau Veritas, a global firm in testing, inspection, and certification, has given the certification to the Hyderabad-based Medha Servo Drives Pvt Ltd system.

Previously, a senior MMRDA official had hinted the ISA certification was being delayed as the system had Chinese components.

While a distance still remains in the monorail being back to functioning in Mumbai, the certification makes it a step closer to being back.

A total of 10 new rakes from Medha have been being delivered incrementally for over a year. The old rakes will be integrated with the new signalling system.

An official from Maha Mumbai Metro Operation Corporation Ltd (MMMOCL), which runs the monorail, said the next step is the clearance from a retired or present commissioner of Metro Railway Safety (CMRS). As this is in contravention to the rules mentioned in the Indian Tramways Act, 1886, a notification from Urban Development (UD) is awaited to give its approval.

“Once a CMRS officer is appointed, inspections will continue, following which there will be some compliances required, as per usual,” said the official, refusing to date when the monorail might restart.

When it does start, another official from the MMRDA said the monorail (from Chembur to Saat Rasta) would work on a frequency of every 8 minutes, with 12 rakes in service. The MMRDA plans to start the Chembur station of the Metro line 2B (Mandale-Andheri), which will be connected with the monorail station, hoping to increase ridership on both the modes of transport.
