Bangalore was the Garden City of India and IS the Silicon valley of India now. Yes, there will be some debate over this statement, but Bangalore is and always will be for me the IT hub or IT Capital of India. So when a new Metro started operation in the city it had to keep up with that image. Having used the Metro in Dubai, I was not very impressed with having the Metro manned with a driver, as opposed to the metro in Dubai which is completely automatic. But thinking as a project Manager I realized that the Capex of introducing an unmanned system was far greater than having the Opex of a Manned system, and in India there is no shortage of labor or rather inexpensive labor so it made sense.
So without having a train that was automatic, it would have to be impressive in terms of technology for me to be able to be impressed with it. On my last trip to India, I did go and see the train in Bangalore, the coach placed at MG Road was a non working display sample but still did not fail to impress. I did a bit of research on the technology used on Namma Metro and I was pleasantly surprised. Here are some things I found out :
The track system
The Bangalore Metro is standard gauge, a system used by most metros worldwide. Narrower than the broad gauge, it allows for greater manoeuvrability, easy ride along curves, laying of tracks even on narrow stretches and control. The standard gauge has a track width of 4ft, 8.5inches, or 1,435mm, while the Indian broad gauge is 5ft, 6inches, or 1,676mm.
Bangalore Metro runs on the ballastless track system used by 70% of the world’s metros. In layman’s language, this means the track does not require stones used on traditional broad gauge track systems to build the track and run the train, as the load is lower than that of a conventional train. The tracks are laid on a concrete slab after assessing the engineering factors. Stones on the conventional track help in balanced construction, while in metro systems concrete slabs are enough.
The Rolling Stock (Coaches)
The rolling stock (coaches/cars) are three stainless steel-bodied wagons. The train will be under the driver’s control, but they are equipped with some Automatic Controls to assist the driver. The seating capacity per train is approximately 1,000, giving more floor area to standing passengers.
The coaches are manufactured by Hyundai Rotem Korea and Mitsubishi Electric Company. BEML has the licence to manufacture the coaches in Bangalore. While Mitsubishi supplied the traction for the coaches, Hyundai Rotem supplied the rolling stock and BEML the coaches.
Power in Third Rail
Electricity for the train will run on a third rail next to the main track. It has an opening at the bottom at certain points from where the train draws its power. The third rail is covered with a yellow shroud, and a person falling on the track won’t be electrocuted. ABB designed, supplied, installed and commissioned four substations to receive and distribute electricity at 66/33 kV, as well as auxiliary and traction substations. ABB will also provide an integrated network management, or SCADA (Supervisory Control And Data Acquisition) system to monitor and control the installations.
Consumer tech in the Coaches
Apart from the technology of the trains themselves, of course something that will not be very visible the trains feature a host of features that are visible and form an important part of the coaches. Guess here are some of the interesting consumer or close to consumer technologies in the metro.
Wi-Fi : Ironically the first thing I am listing is not visible at all, but is increasingly becoming one of the basic requirements especially in a city like Bangalore. Passengers can use their laptops, tablets and the mobile internet to be connected while on transit.
Emergency Voice Comms : Passengers will have emergency voice communication with train staff through a speaker system. Passengers can press a call button to communicate anything urgent to the driver or control centre. Help will be at hand at the next station. The integrated control centre will have direct communication with trains and stations which will be CCTV-fitted with visual and audio service information.
Collision Detection : Bangalore Metro also has automatic train supervision, protection and operation systems — if there’s a train on the same track ahead, the approaching train will sense it and come to a halt at a safe distance.
CCTV Monitoring : Cameras will be installed inside the train as well as stations, and people’s movements will be monitored by an operations control centre at Byappanahalli. In case of any help or emergency, the control room will be able to see what went wrong.
Ticketing : Ticketing, too, is completely automated with just a swipe of the ticket, token or card at a particular point near the entry and exit, enabling the gates to open and close. Recharge of metro cards through mobiles and SMS, a first in the world. What I am waiting for Google India to introduce the features of Google Wallet into the Metro, it will be really interesting.
