Transport in Kolkata
||This article has multiple issues. Please help improve it or discuss these issues on the talk page.
The transport system of Kolkata is a mix of modern mass rapid transport and the old transport modalities like the rickshaws. Kolkata is connected to the rest of India by the National Highways, the extensive network of the Indian Railways, and also by air. Most traffic to North-East India routes via Kolkata.
Howrah Bridge and Vidyasagar Setu are two bridges connecting Kolkata with Howrah over the Ganges. Vivekananda Setu is the third bridge over the river at the northern reach of the city near Dakshineshwar. The fourth one and the newest one is Nivedita Setu. Since Kolkata suffers from traffic congestion like other Indian cities, a network of expressways like Kona Expressway and Belghoria Expressway, flyovers and widening of southern stretch of Eastern Metropolitan Bypass are being created to ease up road traffic.
Kolkata is connected to other parts of India by the National Highways 2, 6, 34 and 117. The Belghoria Expressway connects NH 34 with NH 2 and 6 via the Nivedita Setu while the NH 117 is connected to NH 6 by the Kona Expressway via the Vidyasagar Setu.
Kolkata is well-connected to the rest of India by extensive railway network of the Indian railways. Two divisions of the Indian railways - the Eastern Railway and the South Eastern Railway are headquartered in the city. The two major railway stations of the city are at Howrah and Sealdah. A third terminal called Kolkata has recently been constructed. This station is in North Kolkata and can be reached by a road opposite to the RG Kar Medical College just beyond Shyambazar.
The Circular Rail encircles the entire city of Kolkata, and is at present being extended. A new railway line off-shoot has been built to connect the airport to the lines going to Sealdah.
Underground Metro railway 
Kolkata was the first city in South Asia to have an underground railway system that started operating from 1984. It is considered to have the status of a zonal railway. It is run by the Indian Railways.The Metro is a very well maintained and clean system. The line begins at Dum Dum in the north and continues south through Park Street, Esplanade in the heart of the city till the southern end in New Garia. There are new metro lines being built to serve other parts of Kolkata, including an east west corridor linking Howrah to Salt Lake Sector 5. Trains run every 6–15 minutes from 7 a.m. to 10:30 p.m. from Monday to Saturday and from 2 p.m to 10:00 p.m. on Sunday. Fares are between and at Rs 4-14.
Kolkata has an extensive network of government run and privately run buses. The ticketing system is not centralized one and one has to purchase separate tickets for buses, metros, trams and trains.
The bus tickets are simple paper tickets purchased from the bus conductor after you board the bus. Also there are multiple organisations running buses, a private organisation, and multiple government services like CSTC (Calcutta State Transport Corporation), CTC (Calcutta Tramways Company), WBSTC (West Bengal Surface Transport Corporation) etc. There are also various types of privately run buses.
The private-owned buses are quite typical of Kolkata. The private-owned buses are of two types, the regular ones and the mini-buses. The regular buses are coloured light-blue and yellow. The mini-buses are of brown and yellow colour, and contain lesser number of seats. The mini-buses were started in the late seventies as a relief for the office commuters from the overloaded buses by being a sitting-only service, but this has given way to severely overloaded and crowded mini buses (and other buses too), largely due to the massive population of Kolkata.
The government-run buses are run by several authorities like Calcutta State Transport Corporation (CSTC), South Bengal State Transport Corporation (SBSTC), North Bengal State Transport Corporation (NBSTC), West Bengal Surface Transport Corporation (WBSTC) and the Calcutta Tramways Company (CTC). Government buses have no colour code and can be identified only by the appropriate symbol (CSTC or CTC or WBSTC) on their body. Both the name of the place where the bus is going to, as well as the name of the place where its route originated is mentioned on the bus, - which makes it easy to identify the source and destination of the bus. On the Route Board of the Private/Mini Buses, the ply through (via) stoppages are also mentioned. Further, usually the conductor will call out the names of the stops to come at each halt, so boarding the right bus is not much of a trouble. If in doubt the conductor or any fellow passenger will help out. The buses will often stop to pick up a passenger who waves at the bus.
Recently air-conditioned buses have been introduced by the WBSTC. These buses connects places like the Airport, Barasat, New Town, Sector-V, Santragachchi (a station on the Howrah-Kharagpur railway line) and Tollygunge. The road network in Kolkata is vast.
Long distance buses starting from Kolkata to various places like Bakkhali, Digha, Siliguri and other cities originate from the central bus depot at Dharmatala (popularly known as Esplanade). The tickets can be purchased on spot from the counters or from the conductor on the bus.
Under Jawaharlal Nehru National Urban Renewal Mission air conditioned buses have been included as a part of travel comfort to commuters. Air-conditioned buses are operated by WBSTC (West Bengal Surface Transport Corporation) through outsourcing. These buses are served by Tata Marcopolo Buses and Volvo Low Floor Buses.
A Bus Rapid Transit corridor connecting Ultadanga and Garia through the EM Bypass is currently under construction.
The metered-cabs are mostly of the brand "Ambassador" manufactured by Hindustan Motors. Once in a while, one or two Maruti Omnis, and Tata Indigo can be seen painted in yellow. Recently, air-conditioned cabs (known as "Blue-Arrow") and maroon cabs ( running on Compressed natural gas) have been introduced. The meters - though digital - are generally out-of-date and there is a conversion chart to refer to while converting the meter-reading to the actual fare. But recently ORIX Auto Infrastructure Services Ltd. has introduced an air-conditioned Radio Taxi service in Kolkata with the name 'Kolkata Cab' with fleets consisting of Indigo Marina only, which has gained popularity among the city dwellers because it has comfortable seats, GPS monitoring, digital tamper-proof meters, receipt printers and lost-and-found facilities. Mega Cabs are also there with the same facilities. Some other prospective Radio Taxis to be rolled into the city are Easy Cabs and Meru Cabs.
The Meter Taxi/Cab Rates of Kolkata and howrah have changed and new rates are applicable from 1st of November 2012. The new formula or equation for calculating the same is Meter Reading X 2.4 + 1 = New Fare  
Kolkata is the only city in India to have a tram network. Trams are under the administration of the Calcutta Tramways Company,a government of West Bengal Undertaking, popularly called CTC. The trams are claimed to slow down other traffic, leading to groups who currently voice abolishing the trams. The environment-friendliness and the old charm of the trams attract many people. The tram lines laid in some major roads are being renovated to maintain the tram lines on the same level plane as the rest of the road, thereby smoothening the road. In places, the original central boulevards reserved only for the trams have been removed,the tram-lines are thus brought in the same plane as that of the road.The usable space of the road for vehicle movement has thereby considerably increased. With embedding of tram tracks in the road surface, the over all surface has become smoother, easing the traffic to some extent.
With the tracks now running in the centre of the heavy traffic roads,commuters are encountering difficulties in getting to the trams' stops through the traffic and as a result, less number of people are able to use the tram easily.Mostly trams are found to be running with many seats vacant even during rush hours.This has also caused reduction of revenue for Calcutta Tram Company. One possible remedy towards difficulty of approachability to the trams could be to relay the tracks on outside left and the right sides of the road, adjacent to the footpaths.However,relaying the track may not be possible now as the modification will need enormous expenditure.
Light Railway 
Like Light Rail, a monorail system has been proposed in Kolkata however plans to construct it havn't been specialised yet.
Rickshaws and Auto-rickshaws 
Rickshaws pulled by men and auto rickshaws are commonplace. Many migrants from Bihar and rural Bengal are involved in Rickshaw pulling. Rickshaws are also on the list of probable abolishments on humanitarian grounds. In southern Kolkata, the rickshaws pulled by men have been replaced by cycle rickshaws. Fares are usually set by the rickshaw unions, and are quite reasonable. These rickshaws usually operate over short distances due to the manual effort involved, and mainly run on narrow lanes where buses and auto-rickshaws don't ply.
Auto-rickshaws have become a very common mode of transport for short distances. They are usually not metered, and are usually shared. There are several routes, and the auto-rickshaws of a particular route ply between two distinct places of that route only. Autorickshaws can accommodate 3 people in the backseat, and one passenger in front beside the driver. The fares are usually quite low compared to other metro cities like Delhi and Mumbai, the minimum fare being ₹10.
The Netaji Subhash Chandra Bose International Airport (IATA code:CCU) at Dum Dum (previously known as Dum Dum airport) is the only airport in the city, operating both domestic and international flights. It is a gateway to North-East India, Bangkok, and Bangladesh. The number of people using the airport has consistently increased over the last few years. There is a flying club in Behala. After several years of inactivity it has recently been restored.
Port and water-transport 
Kolkata is also a major port and together with the Haldia dock systems, the Kolkata Port Trust has been amongst top performers in the country. Kolkata Port has regular passenger services to Port Blair from the Netaji Subhas Docks.
Also the twin cities of Kolkata and Howrah are connected by local water ferries through the extensive ghats like Fairlie Ghat, Howrah Ghat, Shibpur Ghat, Prinsep Ghat, Cossipore Ghat, etc. Small boats are used for recreational purpose. There are plans to start utilizing the canals running through the city as water-transport network. The first service is scheduled to start from September 2006 - and would cover the Belgachia-Lake Town stretch of Kestopur Canal.
Besides all this mode of transport, like in other Indian cities, walking is very common way to commute between the workplace and nearest railway station or bus stop. Privately owned cars, though less in number and usage compared to other large cities in India, are growing by leaps and bounds and are slowly becoming the transport of choice for a large number of people being helped by the growing economy, higher per capita income and the easy availability of loans from financial institutions.
