Line 1 is a rapid transit metro line of the Kolkata Metro in Kolkata, West Bengal, India. It consists of 26 operational stations from Dakshineswar to Kavi Subhash, out of which 9 of the stations are elevated, 2 are at-grade and the remaining 15 are underground. With a total distance of 32.13km (19.96miles), the line connects Dakshineswar and New Garia and uses broad gauge tracks. This line was the first underground railway to be built in India, with the first operations commencing in October 1984 and the full stretch that was initially planned being operational by February 1995. On 28 December 2010, Kolkata Metro became the 17th zone of the Indian Railways.[2] Being the country's first, and a completely indigenous process, the construction of the Kolkata Metro Line 1 was more of a trial-and-error affair, in contrast to the Delhi Metro, which has seen the involvement of numerous international consultants. As a result, it took nearly 23 years to completely construct around 15km (09miles) underground railway from Birpara up to Tollygunge.
It connects Line 2 at Esplanade and Line 6 at Kavi Subhash, and will eventually connect Line 3 at Esplanade and Park Street, Line 4 at Noapara and Line 5 at Baranagar. Public transport experts have suggested that the line be extended from Dakshineswar to Bally (where it can connect with Howrah Division of Kolkata Suburban Railway) and eventually to Dankuni, an emerging industrial hub of Kolkata metropolitan region.
The laying of the founding stone was done in 1972, but actual construction of line 1 started only in 1978. Line 1 is 31.38km (19.5miles) long with 26 stations (see above). Running of the first metro car on the line by 1984 was considered a great engineering challenge. Former railways minister A. B. A. Ghani Khan Chowdhury took a massive effort to perform it. The first section opened between Esplanade & Bhawanipore (now called Netaji Bhawan). First day Metro Railway Kolkata was started by Sri Tapan Kumar Nath and Sri Sanjay Sil. There were no connections of this stretch with the two depots at Dum Dum & Tollygunge (Now called Mahanayak Uttam Kumar). So metro cars had to be put down on the track near Esplanade by crane, by directly digging the road surface. Initially, only four-car trains were run until 1986. There were no magnetic gates or escalators at that time and ordinary revolving gates served as exits. The Metro too operated on only a single line. Two years later, line 1 extended up to Tollygunge, at the southern end. At the same time, the metro service was extended to the double line. Magnetic tickets and more entry gates were also introduced at that time. The number of compartments in each train was increased to eight.
Metro service was also started from Dum Dum, at the northern end, to Belgachia in parallel with the extension of the line to the south. But this short portion was not popular and the service was closed down to be restarted when the entire stretch along the north–south corridor was completed.
After 1986 many political incidents hampered the construction, and work almost stopped for nearly six years. After restarting work, the Dum Dum to Shyambazar metro service was started in 1994. This portion was served by four-car trains. Two months later, the Esplanade – Chandni Chowk section was opened and Chandni Chowk – Central section opened three months later. The service from Dum Dum to Tollygunge started in 1995, with Mahatma Gandhi Road metro station, opening in 1996. During this time, more magnetic gates and escalators were added and the revolving gates were slowly phased out.
In 2009, a large number of stations on Line 1 were renamed by then Minister of Railways Mamata Banerjee.[3]
On 22 February 2021, the Noapara – Dakshineswar stretch was inaugurated by Prime Minister Narendra Modi.
On 21 July 2024, the entire stretch from Dakshineswar to Kavi Subhash, crossed 1.92 lakh passenger mark for the first time on a single day.[4]

Mamata Banerjee during her first tenure as the railway minister initiated the project of Tollygunge – Garia metro extension. During her second tenure (2009–2011) she inaugurated the extension, and also introduced new Air Conditioned rakes, manufactured indigenously at the Integral Coach Factory.
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, in the southern end, 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.
The line was extended up to Noapara from Dum Dum on 10 July 2013. The line was further extended from Noapara to Dakshineswar (4.1 km) is now complete & operational. It will be met by a metro line from Barrackpore at Baranagar (12.5 km).[6] Trial runs for this stretch started on 23 December 2020, after delay due to COVID-19 pandemic. The stretch was inaugurated on 22 February 2021 & commercial operations began from the following day.[7]
The stations on this stretch are :
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.
| Total route length | 32.13km (19.96miles) | |
| Stations | 26 (15 underground, 2 on the surface and 9 elevated) | |
| Gauge | 1676mm, Indian Broad Gauge | |
| Cars per train | 8 | |
| Maximum permissible speed | 80km/h | |
| Average speed | NaN1NaN1 | |
| Voltage | 750 V D.C. | |
| Method of current collection | Third Rail | |
| Travel Time: Dakshineswar to Kavi Subhash | 62 minutes (approx.) | |
| Headways | Average 10 minutes | |
| Total estimated cost of the project | (approx.) | |
| Environment control | Air condtioners are used in all trains. |
Platform Screen Doors (PSDs) are a system of full height/half height motorized sliding doors that provide controlled access to the trains and protect the platform edge. PSD work is proposed for all stations in this line to minimize suicidal cases common in this route. This plan was proposed after the successful utilization of Platform Screen Doors to keep the no. of suicidal cases in Kolkata Metro Line 2 to absolute zero.[8]
Metro Railway also plans to extend the platform and viaduct of Dakshineswar metro station by ~ via erection of two new pillars beyond the current length to facilitate a crossover so that the trains can switch tracks faster in order to increase the frequency of services to the Noapara–Dakshineswar stretch.[9]

There was a need to replace non-AC rakes on Line 1 and so during mid 2015 it was announced that Indian Railways for the first time would rope an international train-maker, China Railway Rolling Stock Corporation (CRRC) based in Dalian.[10] As per the tender, 14 new rakes composed of 8 coaches each will be supplied to Kolkata Metro by CNR Dalian, a subsidiary of CRRC Dalian, which will be running on Blue Line. These rakes will be of ultra-modern technology. They will have doors that will be wider than any other metro rails in India. They will have wide vestibules, 2feet wider than the existing trains. The design consists of the aerodynamic front with large doors and LED Lights, and violet colored stripe on silver color body. These rakes are capable of a top speed of . The first of the 14 rakes from Chinese firm Dalian was slated to arrive by December 2017 but got delayed due to various reasons. The first rake finally arrived in Kolkata on 3 March 2019 on a vessel at Netaji Subhash dock of Kolkata port.[11] Each of the 8 coaches of the rake weigh nearly 45 tonnes. The rake was unloaded and taken to Noapara Carshed, after which trial runs and inspection would be carried out before commencing operations. Other 13 rakes are ready, but the shipment got delayed due to the ongoing coronavirus pandemic.
These rakes were under performance trials for more than 20 months as serious problems related to performance of the rake were identified during trials. Some of the issues related to insufficient power to climb up the slopes in the tunnels and higher oscillation in the bogie.[12] [13]
On 17 March 2023, the first Dalian rake was inducted into service. Another 3 rakes will arrive soon.
The whole fleet is vestibuled. Carbodies and mechanical components were made by ICF 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 first underground railway system. The special features incorporated are:
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.
In 2008, the Kolkata Metro Railway experimented with the practice of reserving two entire compartments for women.[14]
This system was found to be ineffective and caused inconvenience for a lot of commuters (including women) and the plan was eventually dropped by the metro authority. But a certain section of seats in each of the eight compartments is reserved for women.
The founder of Delhi Metro, E. Sreedharan said Indian Railways are not experts at urban transport, and misplanned the Kolkata metro from the beginning.[15] A private company should run the metro and can bring it up to standard in five years.
Since Kolkata Metro is under Indian Railways, it can't take its own independent decisions. It has to rely on Indian Railways for everything (like rakes etc.). The rakes are ordered directly from ICF without floating any global tenders.
