Central and Noapara, are exceptions as it has both platforms on the sides as well as in the centre. Dum Dum, Kavi Subhash (New Garia), Rabindra Sarobar & Shobhabazar Sutanuti have connections to interchange with standard railway while Belgachhia, Shyambazar, Esplanade & Kalighat have connections to the tram network. Tram lines also serve Shobhabazar Sutanuti, Mahatma Gandhi Road, Central, Jatin Das Park, Rabindra Sarobar & Mahanayak Uttam Kumar (Tollygunge) stations. Previously Park street & Maidan stations were also served by tram. The EM Bypass can be accessed from the Shahid Khudiram (Briji) metro station.

Extension up to Kavi Subhash Metro Station (New Garia)

Mamata Banerjee during her first tenure as the railway minister initiated the project of Tollygunj – Garia metro extension. During her second tenure (2009–2011) she inaugurated the extension, and also introduced new state-of-the-art Air Conditioned rakes, manufactured indigenously at the Integral Coach Factory, at Perambur near Chennai.

The new extension to Garia Bazar in the south opened to the public on 23 August 2009. The Garia Bazar station was named after Kavi Nazrul. A final extension from Kavi Nazrul (Garia Bazar) to Kavi Subhash (New Garia) was inaugurated on 7 October 2010, bringing the total number of stations to 23. On the same day, two Air-Conditioned rakes were also pressed into service.

Future extension

The plan to extend Line 1 in the north from Dumdum to Dakshineswar (5.2 km) is under execution. The construction of this stretch started in February 2010. It will be met by the metro line from Barrackpore at Baranagar (12.5 km).^[2]

The stations on this stretch will be:

1. Dumdum
2. Ma Sarada Devi (Noapara)
3. Swami Vivekananda (Baranagar)
4. Dakshineswar

Technical features

A metro car is getting ready for the journey towards Kavi Subhash (New Garia) at Dum Dum

Metro construction is of a very complex nature requiring the application of several new technologies in the fields of civil, electrical, signaling and telecommunication engineering. Indian engineers backed by their own experience and supplemented by their studies abroad adopted advanced technologies in the following fields for the first time in India.

• Cut and cover method of construction using diaphragm walls and sheet piles.
• Use of extensive decking to keep the traffic flowing over the cut while construction is in progress underneath.
• Shield tunneling using compressed air and airlocks.
• Ballastless track using elastic fastenings, rubber pads, epoxy mortar, and nylon inserts.
• Air-conditioning and ventilation system for environmental control of stations and tunnels.
• Third Rail current collection system for traction.
• Underground substations with dry-type transformers and SF₆ circuit breakers.
• Tunnel-Train VHF-radio communication system.
• Microprocessor-based train control and supervisory remote control system for substations.
• Automatic ticket vending and checking system.

Salient features

Rolling stock

The whole fleet is vestibuled. Carbodies and mechanical components were made by ICF Chennai with electrical components made by NGEF, Bangalore. The fleet is unique in that it is the only railroad equipment in India with end-mounted cab doors (except for some of the WAG-6 series locomotives).

ICF has specifically designed, manufactured and supplied these cars for the Kolkata Metro Underground Railway System. The special features incorporated are:

• Traction power supply through third rail current collection system.
• Automatic door opening/closing and continuous monitoring of the transit.
• Automatic Train Stop (ATS) system which will automatically apply the brakes in case of human failure.
• Automatic train operation (ATO) with the driver acting as the train supervisor (optional).
• A public address system is provided on the trains to announce approaching stations. A central dispatcher can contact any of the train crew and also make important announcements directly to passengers over the system.

With all these features, the design and manufacturing process of these cars to a very high standard of reliability and safety has been a challenge. This was achieved without any technical collaboration. The entire fleet is capable of carrying 2356 passengers.

From October 2010, the process of phasing out of the current class of rolling stock was started and replaced by new air-conditioned cars 13 of which have been already pressed into service. Out of a total of 18 trainsets (non-AC) owned by the Kolkata Metro, 11 are supposed to be retired within a few years and the remaining seven will be rebuilt with new features including air conditioning, which is badly needed.

The 13 state-of-the-art AC rakes have the following features:-

• Microprocessor controlled temperature and humidity control inside the trains.
• Fully automatic and digital operation of the train including emergency braking in the event of human failure or an emergency.
• LCD displays inside the motormen's cabins.
• Low external and internal noise level.
• Maximum speed of 80 km/h and Average speed is 55 km/h.
• Multilingual Electronic LED sign boards both inside and outside the train.
• Public address system.
• Multi-Reflector Head lamps.
• LED-based tail lamps.
• Third rail system of current collection.
• Continuous monitoring of the transit.

The new air-conditioned rolling stock was manufactured by ICF in collaboration with BHEL and Knorr Bremse, Germany.

Features of token system

1. Tokens is being reused, hence saving paper which also reduces the chance of damage done to the paper pasted tickets.
2. Passengers can enter the station within 30 secs. This will ensure smooth passage of commuters.
3. This will also help to improve security in the sense that earlier many people used to travel without tickets.

Smart cards

Smart cards were also introduced a month later after the introduction of the token system. The advantages of using Smart cards is the flexibility which allows daily passengers to travel into any zone without worrying about buying tokens for the exact zone. Another advantage it offers over regular tokens is the reduced effective cost of travel. A fully refundable security deposit of Rs 100 has to be made to obtain these smart cards. Presently the deposit is Rs 60.
