Finally, Mumbai gets its Metro
Jaws will drop, the traffic will stop, when the Metro goes from the top. Watch the magic of Mumbai Metro unfold in this video.
The regular services will be operated daily from 5.30 a.m. and continue till midnight with a total of 16 rakes deployed on the line, serving the glamour and IT centres of Versova and the business and manufacturing areas of Ghatkopar at a whopping top speed of 80 kmph.
Each coach of the colourful four-coach rakes has a capacity of around 375 commuters, with a total capacity of around 1,500 commuters per service. The Metro will be zooming above the city between the two points – Versova-Ghatkopar – with a total of 12 elevated stations en route.

Mumbai’s Metro-3 will be one of the few in the world to run on AC
It seems the authorities have ignored the wisdom of agencies running the most efficient Metros in the world, and chosen to run the 32-km-long Colaba-Bandra-Seepz (CBS) Metro corridor, or Metro line-3, on alternating current (AC).
While 97 per cent of the underground Metro corridors across the world run on direct current (DC), say experts, the CBS rail will run on AC, which is more intensive in terms of cost as well as labour.
Experts feel there may be a 15 per cent cost escalation in the project due to this, since it requires more digging for the rail to work on AC. Additionally, there can also be a problem of dumping the muck that would be excavated while tunnelling.
Euston to Watford line in London, UK, North London Line between Richmond and Gunnersbury, South West Trains’ Putney Bridge to Wimbledon, and rails in Russia and Chicago and New York are some of the Metros that run on DC.
Sources from MMRDA said that bidders for Metro line-3 are also in favour of the DC model. Incidentally, S P Khade, director (technical), MMRDA, while writing in a magazine specific to the railway sector, has said that the Delhi Metro’s decision to adopt 25KV-AC instead of 1,500V-DC was not a good idea.
