Rail transport in India

In 1832, the proposal to construct the first railway line in India at Madras was made.^[8][9] In 1835, a railway track was constructed between Red Hills and Chintadripet in Madras and became operational in 1837. It was hauled by a rotary steam engine imported from England and was used for ferrying granite.^[10]

The Madras Railway was established in 1845.^[9] Temporary railway lines were built such as the Godavari Dam Construction Railway at Dowleswaram by Arthur Cotton to supply stone for the construction of a dam over the Godavari River in 1845 and the Solani aqueduct railway, built by Proby Cautley in Roorkee to transport construction materials for an aqueduct over the Solani river in 1851.^[9] On 1 August 1849, the Great Indian Peninsular Railway was incorporated with a guarantee system providing free land and guaranteeing five-percent rates of return to private English companies building railways.^[9] In 1852, a steam locomotive imported from England was tried at Byculla.^[11]

In 1853, the first passenger train on 1,676 mm (5 ft 6 in) broad gauge ran for 34 kilometres (21 mi) between Bombay and Thane which had 14-carriages carrying 400 people, hauled by three steam locomotives: the Sahib, Sindh and Sultan.^[12][13] The Great Southern of India Railway Company was established with its headquarters in England in 1853.^[14] The Thane viaducts, the first railway bridges, were built over the Thane creek when the Mumbai-Thane line was extended to Kalyan in May 1854. Eastern India's first passenger train ran 39 km (24 mi) from Howrah, near Kolkata, to Hoogly on 15 August 1854.^[9] The construction of 97 km (60 mi) line in the South between Royapuram in Madras and Arcot started in 1853, which became operational on 1 July 1856.^[15] The first workshops were established by GIPR at Byculla in 1854 and Madras Railway at Perambur in 1856. The Bombay, Baroda, and Central India Railway (BB&CI) was incorporated in 1855 and Eastern Bengal Railway in 1858.^[16][17] The Carnatic Railway was founded in 1869.^[14] On 24 February 1873, a horse-drawn 3.8 km (2.4 mi) tram opened in Calcutta between Sealdah and Armenian Ghat street.^[18] On 9 May 1874, a horse-drawn tramway began operation in Bombay between Colaba and Parel.^[19] The Great Southern of India Railway and the Carnatic Railway merged in 1874 to form the South Indian Railway.^[20] In 1879, the Nizam's Guaranteed State Railway was established which built railway lines across the then Hyderabad State.^[21] In 1877, an Ajmer built F-1/734 Steam Locomotive became the first indigenously built locomotive in India.^[22] East Coast State Railway was established in 1890.^[23] In 1897, lighting in passenger coaches was introduced with Jodhpur Railway, the first to introduce electric lighting as standard fixtures.^[9] In 1908, Madras Railway merged with Southern Mahratta Railway to form the Madras and Southern Mahratta Railway.^[24] Pamban bridge, the first sea bridge was opened on 24 February 1914.^[25] In 1920, electric lighting of signals was introduced between Dadar and Currey Road in Bombay.^[26]

The first railway budget was presented in 1924.^[9] The Oudh and Rohilkhand Railway was merged with the East Indian Railway Company (EIR) in the same year.^[27] On 3 February 1925, the first electric train ran between Victoria Terminus (VT) and Kurla, hauled by a SLM electric locomotive on 1500 V DC traction.^[28] Later, the VT–Bandra section was electrified and the first Electric Multiple Units (EMU) were introduced in with 1.5KV DC units imported were from Cammell Laird and Uerdingenwagonfabrik.^[29] On 1 April 1929, Grand Trunk Express commenced operations between Peshawar in the North Western Railway and Mangalore with two coaches detached and connected to Madras further.^[30][31] The Frontier Mail made its inaugural run between Bombay and Peshawar in 1928.^[32] Technical advancements led to automatic colour light signals become operational between Bombay and Byculla in 1928.^[33] In the subsequent years, the route from Bombay to Poona was electrified and in June 1930, the first deluxe train, Deccan Queen began running, hauled by a WCP-1 locomotives with seven coaches along the route.^[34] The Grand Trunk express commenced operating as a dedicated daily train between Madras and Delhi from 1 September 1930.^[35] Chennai suburban railway started operating in 1931 with a single metre gauge line from Chennai Beach to Tambaram.^[36] In 1944, all the railway companies were taken over by the Government.^[37]

Beginning 1926 and for statistical purposes, the Government of British Raj classified Indian railway systems according to three classes. It was a similar system to the Railroad classes in North America.^[38][39]

Trams, industrial and port railways were recorded separately and independently of turnover.In terms of net revenue, East Indian Railway was the largest company in 1927 with 86,881,000 rupees. Followed by the North Western State Railway with 57,343,000 rupees and the Great Indian Peninsula Railway with 56,215,000 rupees.^[40] No further reclassification was carried out after 1942, but the rankings remained in use until the mid-1950s.^[38][41]

The first locomotive manufacturing unit at Chittaranjan was commissioned in 1950.^[42] In December 1950, the Central Advisory Committee for Railways approved the plan for re-organising Indian Railways into six regional zones with the Southern (14 April 1951), Central (5 November 1951), and Western (5 November 1951) zones being the first to be created.^[43] On 14 April 1952, the Northern Railway, the Eastern Railway and the North Eastern Railway were created.^[43] In 1952, fans and lights were mandated for all compartments in passenger trains and sleeping accommodations were introduced in coaches.^[9] In 1953, the Indian Railways completed hundred years of operation which was commemorated by multiple events and a commemorative postage stamp.^[44][45] The first diesel locomotive used in India was fabricated by North British Locomotive Company in 1954.^[46] On 1 August 1955 the South-Eastern Railway was split from the Eastern Railway, and, the following year, divisional systems of administration were set up for the various regional zones. The first rail coaches were manufactured in India from 1956 when the Integral Coach Factory was established at Madras.^[47] In 1956, the first air-conditioned train plied between Howrah and New Delhi.^[48] In 1958, the North-Eastern Railway split to form a new Northeast Frontier Railway.^[43]

In 1957, Indian Railways adopted 25 kV AC traction with the first trial runs operating with the WAM-1 locomotives in 1959 and commercial services beginning in August 1960.^[29] In 1960, the Railway Board of India commissioned a study to increase the speed of passenger trains to 160 km/h (99 mph) with an intermediate stage of 120 km/h (75 mph).^[49] Research Design and Standards Organisation (RDSO) started work on the same in 1962 with field trials commencing in 1967 with coaches manufactured by the Integral Coach Factory at Madras and hauled by diesel locomotives.^[49] The first containerized freight rail transport began between Bombay and Ahmedabad in 1966.^[9] In 1966, electrification of several suburban tracks around Delhi, Madras and Calcutta were completed with the 25 kV AC system. In 1969, the Government of India announced the introduction of a new express train capable of reaching speeds of up to 120 km/h (75 mph) in the railway budget and the first Rajdhani Express was flagged off from New Delhi to Howrah in March 1969.^[50][51] In 1974, Indian Railways endured a 20-day strike.^[52][53] In 1979, the Main Line Electrification Project was reconstituted into the Central Organisation for Railway Electrification (CORE).^[54] In 1980, the WAP-1 electric locomotives reached a speed of 130 km/h (81 mph).^[55]

The first metro rail was introduced in Calcutta on 24 October 1984 with the line between Esplanade and Bhowanipore.^[56] In 1986, computerized ticketing and reservations were introduced by Indian Railways.^[57] In 1988, the first Shatabdi Express was introduced between New Delhi and Jhansi.^[9] Two years later, the first self-printing ticket machine (SPTM) was introduced in Delhi.^[58] In 1993, air-conditioned three-tier and sleeper were introduced.^[9] In 1995, Chennai MRTS became the first operational elevated railway line in India.^[59] In 1995, Delhi Metro Rail Corporation, a joint venture between Government of India and Government of Delhi was established.^[60] Centralized computer reservation system was deployed in Delhi, Mumbai and Chennai in September 1996, coupon validating machines (CVMs) were introduced at Mumbai CSMT in 1998 and the nationwide concierge system began operation on 18 April 1999.^[9] In 1999, the South East Central Railway zone was established and on 6 July 2002, the East Coast, South Western, South East Central, North Central, and West Central zones were created.^[61][43]

The Indian Railways website went online in February 2000. Indian Railways Catering and Tourism Corporation (IRCTC) was incorporated in 1999 and online ticketing was introduced on 3 August 2002 through IRCTC.^[62] The first line of the Delhi Metro was inaugurated on 24 December 2002.^[63] In 2012, Western Railway switched completely to AC traction with Central Railway following it in 2016.^[64][65] On 1 February 2014, Mumbai Monorail became the first operational monorail system in India.^[66] In 2015, the first Compressed Natural Gas (CNG) powered trains were rolled out.^[67] On 5 April 2016, Gatimaan Express, then India's fastest train with a maximum speed of 160 km/h (99 mph), made its first run from New Delhi to Agra Cantonment.^[68]

The central government approved the merger of the Rail and General budgets from 2017.^[69] On 31 March 2017, Indian Railways announced a target of electrifying the entire rail network would be electrified by 2023.^[70] In March 2020, Indian Railways announced a nationwide shutdown of passenger service to combat the COVID-19 pandemic in India with the freight operations continuing to transport essential goods.^[71][72][73] The railways resumed passenger services in a phased manner in May 2020.^[74]

Starting in the 2010s, various infrastructure modernization projects have been undertaken including high-speed rail,^[75][76] redevelopment of 400 stations,^[77] doubling tracks to reduce congestion,^[78] refurbishing of coaches,^[79][80] Global Positioning System (GPS)-enabled tracking of trains^[81] and modernization of locomotives.^[82][83] In 2018, a semi-high speed self-propelled train-set capable of reaching speeds of over 160 km/h (99 mph) was rolled out from ICF and the Vande Bharat Express was launched in 2019.^[84][85] Indian Railways announced plans to become a net-zero carbon emission railway by 2030 and has implemented rainwater harvesting at stations,^[86] reforestation along the tracks,^[87] introduction of solar-powered trains,^[88] installation of solar and wind power generation facilities,^[89] and sustainable LED lighting at all the stations.^[90] Indian railways removed all unstaffed level crossings by 2019 with staffed level crossings being replaced by bridges.^[91] Other safety projects include the extension of an automated fire alarm system to all air-conditioned coaches and GPS-enabled Fog Pilot Assistance System railway signalling devices.^[92] In 2020, Indian Railways allowed the operation of private passenger trains for the first time with the first train flagged off from Coimbatore in June 2022.^[93][94]

A covered wagon (left) and a WDG-4G diesel locomotive used to haul freight

Indian Railways hauls variety of cargo to cater to various requirements and have specialized rolling stock corresponding to the cargo hauled. There are 243 types of rolling stock used for cargo operations.^[96] These include covered wagons, boxcars, flat wagons, flatbeds, open wagons, hoppers, containers, automobile carriers, defense vehicle carriers and tankers.^[97] The freight cars can often carry loads from 10 to 80 tonnes per car depending on the configuration.^[97] A new wagon numbering system was adopted in Indian Railways in 2003.^[98]The requirement of wagons was previously met by Bharat wagon and engineering with the procurement and manufacturing now done by both in public and private sector.^[1] The earliest goods trains in the 1800s were hauled by imported steam locomotives.^[9] Locomotives are classified by various parameters including function (passenger/goods/mixed).^[99] Indian Railways uses dedicated electric locomotives such as WAG series (Wide AC Goods), dedicated diesel locomotives such as WDG series and diesel locomotives of mixed usage such as WDM series to haul freight trains.^[100][101]

Indian railways operates a 65,093 km (40,447 mi) 1,676 mm (5 ft 6 in) broad gauge network which is equipped with long-welded, high-tensile 52kg/60kg 90 UTS rails with pre-stressed concrete (PSC) sleepers and elastic fastenings.^[1] These tracks are shared by both freight and passenger trains with passenger trains often priortized on the network. The Dedicated Freight Corridor Corporation of India was established in 2006 to construct dedicated freight corridors to reduce congestion, increase speed and reliability and proposed upgradation of existing goods sheds, attracting private capital to build dedicated logistics terminals.^[102]

The first freight rail was operated between Bombay and Ahmedabad in 1966.^[9] Indian Railways ferries various commodities and cargo to cater to various industrial, consumer, and agricultural segments. Apart from dedicated freight trains, parcels, mail and small cargo are carried on specialized carriages attached to passenger trains.^[103] In 2022–23, Indian Railways operated 8,479 trains on average daily and transported 1418.1 million tonnes of freight.^[1] Indian Railways has historically subsidized the passenger segment with income from the freight business and hence, freight services were unable to complete other modes of transport on both cost and speed of delivery, leading to continuous erosion of market share till the early 2000s.^[104] To counter this, Indian Railways aimed to increase speed and reliability through various means including operating time-tabled freight trains and tweaking with the freight pricing/product mix.^[105] End-to-end integrated transport solutions such as roll-on, roll-off (RORO) service, a road-rail system pioneered by Konkan Railway in 1999 to carry trucks on flatbed trailers has been extended to other routes.^[106]

ICF coach

LHB coach

The early rail coaches were based on a prototype by a Swiss company and were termed as ICF coaches after Integral coach factory (ICF), the first coach manufacturing unit in India.^[47] These coaches, manufactured from 1955 to 2018, were largely in use till the early 2010s.^[107] From the late 1990s, the ICF coaches were replaced by safer and newer LHB coaches designed by Linke-Hofmann-Busch of Germany.^[108][109] In the late 2010s, Indian railways started upgrading the coaches of select trains from LHB to new Tejas coaches with enhanced features.^[110][111] As of March 2022, Indian Railways' had 84,863 passenger coaches.^[1] Coaches are manufactured by five manufacturing units of the Indian Railways and public sector companies BEML and BHEL.^[112] The coaching stock have unique five or six digit identifiers. Till 2018, the first two digits indicating the year of manufacture and the last three digits indicating the class.^[113] In 2018, the numbering system was changed with the first two digits indicating the year of manufacture and the last four digits indicating the sequence number.^[114]

Track

As of 31 March 2022, Indian railway network spans 128,305 km (79,725 mi) of track length, 102,831 km (63,896 mi) of running track length and 68,043 km (42,280 mi) of route length.^[1] Track sections are rated for speeds ranging from 80 to 200 km/h (50 to 124 mph), though the maximum speed attained by passenger trains is 160 km/h (99 mph). Spanning 65,093 km (40,447 mi) 1,676 mm (5 ft 6 in) broad gauge is the most used gauge with 1,000 mm (3 ft 3+3⁄8 in) metre gauge metre gauge and 762 mm (2 ft 6 in) narrow gauge and 610 mm (2 ft) narrower gauge tracks limited to certain routes.^[1] Indian Railways uses a range of signalling technologies and methods to manage its train operations based on traffic density and safety requirements.^[1] It primarily uses coloured signal lights, which replaced the earlier semaphores and disc-based signalling.^[115][116]

Stations

As of March 2022, Indian Railways manages and operates 7,308 stations.^[1] Prior to 2017, the stations were classified into seven categories based on their earnings.^[117] Since 2017, Indian Railways categorizes the stations by commercial importance into three different categories namely Non Suburban Group (NSG), Suburban Group (SG) and Halt Group (HG). These are further subdivided into subcategories based on their commercial importance (NSG 1–6, SG 1-3 and from HG 1–3).^[118][117] The commercial importance of a station is determined by taking into account its passenger footfall, earnings and strategic importance and these categories are used to determine the minimum essential amenities required by each station.^[119][118]

Travel classes

Indian Railways offers various travel classes on its coaches.^[120] For the purpose of identification in passenger trains, coaches in a train-set are assigned an alpha-numeric code. The first letter identifies the coach class and the second letter identifies the coach number.^[121] The berths and seats are numbered by an alphanumeric code with the letter(s) identifying the berth/seat type and numbers identifying the position. In standard coaches, the berths and seats are classified as follows:^[122]

Coach code (First digit)^[121]

Saloon coaches are also available for chartering which are equipped with a bedroom and kitchen and can be attached to normal trains.^[142]

Trains

Express trains of India

Rajdhani Express

Shatabdi Express

Indian Railways operates various classes of passenger and express trains. The trains are classified basis average speed and facilities with express trains having fewer halts, priority on rail network and faster average speed. The trains are identified by five digit numbers with train-pairs traveling in opposite directions usually labelled with consecutive numbers.^[143] Express trains often have specific unique names for easy identification.^[144] In 2018–19, Indian Railways operated 13,523 passenger trains on average daily and carried 8.44 billion passengers.^[145] India Railways operates various categories of express trains including Rajdhani Express, Shatabdi Express, Garib Rath Express, Double Decker Express, Tejas Express, Gatimaan Express, Humsafar Express, Duronto Express, Yuva Express, Uday Express, Jan Shatabdi Express, Sampark Kranti Express, Vivek Express, Rajya Rani Express, Mahamana Express, Antyodaya Express, Jan Sadharan Express, Suvidha Express and Intercity Express.^[144]

In 1986, computerized ticketing and reservations were introduced before which ticketing was done manually.^[57] Self-printing ticket machines (SPTM) were introduced in 1988.^[58] Centralized computer reservation system was deployed in September 1996.^[9] The ticketing network at stations is computerized with the exception of few stations. The Indian Railways website went online in February 2000 and online ticketing was introduced on 3 August 2002 through IRCTC.^[62] Indian Railways now provides multiple channels for passengers to book tickets through website, smartphone apps, SMS, rail reservation counters at train stations, or through private ticket booking counters. Reserved tickets may be booked up to 120 days in advance and confirmed reservation tickets will show the passenger and fare details along with berth or seat number(s) allocated to them on the ticket.

In case of no confirmed reservation, a wait-list number is assigned and wait-listed tickets get confirmed if there are cancellations of already reserved tickets. Reservation against cancellation tickets is an intermediate category between the waiting and confirmed lists in sleeper classes which allows a ticket holder to board the train and share a berth.^[146] Reserved tickets can be booked by passengers who want to travel at short notice at higher fares through the Tatkal train ticket, where no refund is applicable on cancellation.^[147] A valid proof for the purchase of ticket along with photo identification is required to board the train.^[148] Unreserved tickets for short distance or unplanned travels may be purchased at stations or through UTS mobile app at any time before departure.^[149] Holders of such tickets may only board the general or unreserved coaches. India has some of the lowest train fares in the world, and lower class passenger fares are subsidised.^[150] Discounted fares are applicable for railway employees, senior citizens (over age 60), the differently-abled, students, athletes, patients and those taking competitive examinations. Seats of lower class of accommodation are reserved for women or senior citizens in some trains.^[151]

In 1980, the WAP-1 electric locomotives reached a speed of 130 km/h (81 mph).^[152] WAP-5 class locomotives, initially imported from ABB in 1995 and later manufactured at Chittaranjan Locomotive Works in India, reached 184 km/h (114 mph) in trials. The locomotive later set an Indian speed record by hauling a train between Delhi and Agra at a speed of 160 km/h (99 mph) in 2014.^[153] In 2018, a modified WAP-5A locomotive reached speeds of 200 km/h (124 mph) in trials.^[154] In 2018, Integral Coach Factory in Chennai, rolled out a semi-high-speed EMU train-set, capable of reaching 180 km/h (110 mph).^[84][85] These trains have eight or sixteen coaches with driver cabins on both ends, which eliminates the time needed for turnaround at the terminal station with faster acceleration and deceleration, enabling the train to travel at a top speed for longer distance.^[155][156] For high-speed rail, the Indian railways will construct bullet train assembly facilities on a public-private participation (PPP) model with Japanese companies setting up manufacturing facilities in India to build the parts for bullet train sets.^[157]

In 2009, Indian Railways envisioned a plan to increase the speed of passenger trains to 160–200 km/h (99–124 mph) on dedicated conventional tracks and improve the existing conventional lines on 1,676 mm (5 ft 6 in) Broad gauge to handle speeds of up to 160 km/h (99 mph).^[158] On 25 July 2013, Government of India established the High Speed Rail Corporation under Rail Vikas Nigam (RVNL) for the implementation of high-speed rail corridor projects.^[158][159] In 2014, the Diamond Quadrilateral high-speed rail network project was launched by Government of India and is envisioned to connect the four major metro cities of India namely: Chennai, Delhi, Kolkata and Mumbai.^[160][161] As of 2023^[update], India does not have any operational high-speed tracks with the 174 km (108 mi) segment of track in the Tughlakabad– Agra Cantonment section supporting semi-high speeds of up to 160 km/h (99 mph).^[162] By 2026, Ministry of Railways envisaged to have top speeds of 300–350 km/h (190–220 mph) with trains running on elevated corridors to isolate high-speed train tracks to prevent trespassing.^[163] Multiple feasibility studies have been done and probable routes have been identified.^[164][165] In 2017, a 508 km (316 mi) standard gauge line between Mumbai and Ahmedabad was approved for construction and is expected to be operational by 2028.^[166][167] RapidX system operating on 1,435 mm (4 ft 8+1⁄2 in) Standard gauge tracks with Namo Bharat train-sets capable of supporting speeds of up to 180 km/h (110 mph), became operational with the partial opening of Delhi–Meerut line in 2023.^[168]

Rajdhani Express, introduced in 1969 with a maximum speed of 120 km/h (75 mph) was the fastest train service in the country in the 1970s.^[50] Shatabdi Express introduced in 1988, were capable of running at a maximum speed of 130 km/h (81 mph).^[169][170] In April 2016, WAP-5 hauled Gatimaan Express became the fastest commercial train in India, with a maximum operational speed of 160 km/h (99 mph).^[171] In 2019, the first Vande Bharat Express entered commercial service with a maximum operational speed of 160 km/h (99 mph). The actual operating speed was much lower due to track restrictions and congestion with top speeds restricted to 130 km/h (81 mph) for most trains.^[172] In October 2023, Namo Bharat, built for RapidX by Alstom was launched and is capable of reaching speeds of up to 180 km/h (110 mph).^[173] In December 2023, two modified WAP-5 locomotives were used to haul the Amrit Bharat Express in a push-pull configuration, capable of reaching speeds of up to 160 km/h (99 mph).^[174][175]

Mountain Railways of India

Darjeeling

Kalka-Shimla

Nilgiri

Mountain Railways of India refer to three rail lines operated by Indian Railways in hilly terrain. Darjeeling Himalayan Railway, a 610 mm (2 ft) narrow-gauge railway in the Lesser Himalayas of West Bengal was opened in 1881.^[176] The mountain railways were designated as World Heritage Sites in 1999.^[176] The Kalka-Shimla Railway, a 762 mm (2 ft 6 in) narrow-gauge railway in the Siwalik Hills of Himachal Pradesh started operating in 1903. The Nilgiri Mountain Railway, a 1,000 mm (3 ft 3+3⁄8 in) metre gauge rack railway in the Nilgiri Hills of Tamil Nadu was opened in 1908 and is the only operational rack railway in India.^[177][176] These railways operate with its own dedicated fleet of locomotives and coaches.^[178]

Indian Railways operates tourist trains and coach services on popular tourist circuits in different regions of the country. It operates luxury tourist trains such as Maharajas' Express, Palace on Wheels, Golden Chariot and Deccan Odyssey, deluxe tourist trains such as Mahaparinirvan Express.^[1][179] It also operates heritage and exhibition trains on special circumstances.^[180]

India shares land border with multiple countries and have rail-links with some of them. Bangladesh is connected to West Bengal with a construction of new rail link connecting Tripura with Akhaura.^[181][182] Two rail links to Nepal exist as of 2021, with a third under construction.^[183] There is an existing railink with Pakistan through Attari–Wagah border.^[184]

The state-owned Indian Railways has an almost monopoly over rail operations. There are a few private railway lines used exclusively for transporting freight and to connect with the wider network. Private railways are operated by various ports such as Mumbai, Kolkata, Chennai, Visakhapatnam, Pipavav and the Bhilai Steel Plant. The Tata Group operates a few funicular railways.^[185] In 2020, Indian Railways allowed the operation of private passenger trains for the first time with the first train flagged off from Coimbatore in June 2022.^[93]

In the 1960s, Electric multiple units (EMU) were developed for short-haul and suburban rail transit.^[186][187] On short-distance routes, Mainline electrical multiple unit (MEMU) and Diesel electrical multiple unit (DEMU) trains are also run. These train sets run in formation of 6, 9, 12 or 15 coaches and a three-car set is typified by a motor coaches and two passenger coaches.^[188][189] These train-sets are self-propelled with capability for faster acceleration or deceleration.^[190]

Suburban lines were built starting with Bombay in 1853, followed by Calcutta and Madras in the later years. The first 1.5kV DC electrified tracks became operational in the late 1920s and early 1930s.^[188] In 1957, 25 kV AC traction was adopted for suburban lines.^[29]

The first suburban electric trains were introduced in Bombay in 1925.^[188] Chennai suburban started operating in 1931 and Kolkata in 1957.^[198][199] Opened in November 1995, Chennai MRTS became the first operational elevated railway line in India.^[36] Indian Railways operates suburban railway systems across the cities of Mumbai (suburban), Chennai (suburban and MRTS), Kolkata (suburban) and Secunderabad (MMTS) covering six railway zones.^[188] Suburban networks issue unreserved tickets valid for a limited time or season passes with unlimited travel between two stops for a period of time.^[200][201]

Metro trains use electric multiple unit train-sets manufactured by various state-owned and private companies.^[202][203] The trains operate on 25 KV AC through an overhead catenary system with a maximum speed of 120 kilometres per hour (75 mph).^[204]

The urban rail transit in India consists of systems such as rapid transit (Metro), suburban rail (operated by Indian railways), light rail (Metrolite), tram, regional rail and monorail. As of 2023, India has the fourth longest length of metro lines with 895 kilometres (556 miles).^[205] Urban rail transit systems in India mostly use standard gauge tracks except a single line of Kolkata Metro and three lines of Delhi Metro which use the same broad gauge tracks as main-line railways.^[4] These systems are operated by rail corporations independent of Indian Railways.^[206] All metro routes are electrified with DC or 25 kV AC traction with many metro routes employing the third rail method for electric traction.^[207]

Metro trains operate in Kolkata, Delhi, Bengaluru, Chennai, Mumbai, Pune, Hyderabad, Jaipur, Kochi, Nagpur, Ahmedabad and Lucknow. Gurgaon has a Metro system operated by a private organisation. Metro tracks are being constructed or planned in all million-plus cities in the country.^[208]
