80-394: [REDACTED] The Chennai Suburban Railway is a commuter rail system in the city of Chennai , Tamil Nadu , India, operated by the Southern Railways branch of Indian Railways . It is the second largest suburban rail network in terms of route length and the third largest in terms of commuters in India. Around 1,000 services are operated daily between 4:00 a.m. and midnight. It is

160-521: A black wheel base and featured wide sliding doors, a better-designed seating arrangement, and thick glass fronts. The new carriages were parked in Tambaram station. By March 1931, the construction works were completed, and the first electrically operated rail service in Madras began on 2 April 1931 between Madras Beach and Tambaram , which became the earliest metre gauge to be electrified in the country. It

240-651: A city's central business district, and often share right-of-way with intercity or freight trains. Some services operate only during peak hours and others use fewer departures during off peak hours and weekends. Average speeds are high, often 50 km/h (30 mph) or higher. These higher speeds better serve the longer distances involved. Some services include express services which skip some stations in order to run faster and separate longer distance riders from short-distance ones. The general range of commuter trains' travel distance varies between 15 and 200 km (10 and 125 miles), but longer distances can be covered when

320-413: A headway rather than a published timetable and use dedicated tracks (underground or elevated), whereas commuter rail often shares tracks, technology and the legal framework within mainline railway systems, and uses rolling stocks with more seating and higher speed for comfort on longer city-suburban journeys. However, the classification as a metro or rapid rail can be difficult as both may typically cover

400-581: A metropolitan area exclusively, run on separate tracks in the centre, and often feature purpose-built rolling stock. The fact that the terminology is not standardised across countries (even across English-speaking countries) further complicates matters. This distinction is most easily made when there are two (or more) systems such as New York's subway and the LIRR and Metro-North Railroad , Paris' Métro and RER along with Transilien , Washington D.C.'s Metro along with its MARC and VRE , London's tube lines of

480-412: A new line between Beach and Egmore and two lines between Egmore and Tambaram was announced as part of the suburban remodelling initiative of South Indian Railways. The rolling stock, consisting of rigid wooden-bodied coaches, were built by Metro-Cammell . On 27 December 1930, the first consignment of 25 electric carriages from England was received by the railway. The trains were painted in dull green with

560-599: A parking lots for empty rakes of express trains. By 2006, the suburban system carried about 500,000 commuters daily, which rose to about 700,000 by 2009. By 2011, this has increased to 960,000 passengers a day. As of 2006, 24 rakes, each with 9 cars, are operated every day between Tambaram and Chennai Beach, with a plan to increase the fleet to 30 rakes. By the end of 2013, all the 9-unit EMU services in Chennai Beach–Tambaram–Chengalpattu section were expected to be converted into 12-unit services. With this

640-548: Is an exclusive line of the Chennai suburban railway as it runs elevated for most of its section. Moreover, the route is unique as it is exclusively used to run suburban EMU trains. No express trains, MEMU trains or passenger trains ply on the MRTS route. The MRTS currently runs from Chennai Beach to Velachery. However, the MRTS line is being extended from Velachery to St Thomas Mount (as phase 2 extension), where it will intersect with

720-935: Is especially the case for lines operated by Korail , such as the Gyeongui-Jungang Line , the Gyeongchun Line , the Suin-Bundang Line , or the Gyeonggang Line . Even some lines not operated by Korail, such as the AREX Line, the Seohae Line or the Shinbundang Line mostly function as commuter rail. Lastly, even for the "numbered lines" (1–9) of the Seoul Metropolitan Subway which mostly travel in

800-603: Is heavily used by commuters in the Greater Tokyo Area , who commute between 100 and 200 km (62 and 124 mi) by Shinkansen . To meet the demand of commuters, JR sells commuter discount passes. Before 2021, they operated 16-car bilevel E4 Series Shinkansen trains at rush hour, providing a capacity of 1,600 seats. Several lines in China, such as the Beijing–Tianjin Intercity Railway and

880-417: Is often a case of asset sweating , by using a single large combined fleet for intercity and regional services. Loco hauled services are usually run in push-pull formation, that is, the train can run with the locomotive at the "front" or "rear" of the train (pushing or pulling). Trains are often equipped with a control cab at the other end of the train from the locomotive, allowing the train operator to operate

960-963: Is often used in contrast to rapid transit or light rail . Some services share similarities with both commuter rail and high-frequency rapid transit ; examples include New Jersey Transit in the U.S., German S-Bahn in some cities, the Réseau Express Régional (RER) in Paris, the S Lines in Milan, many Japanese commuter systems, the East Rail line in Hong Kong, and some Australasian suburban networks, such as Sydney Trains . Many commuter rail systems share tracks with other passenger services and freight . In North America, commuter rail sometimes refers only to systems that primarily operate during rush hour and offer little to no service for

1040-472: Is one of the two branch lines of the western line (the other one is Pattabiram east depot line, which is still operational) and gets divided from Villivakkam junction. This is one of the two lines that ends within the Chennai city limits (the other one is the MRTS corridor, which is still operational). Total length of this line from Villivakkam junction to Anna Nagar West railway station is 5 km. This line consist of two stations, namely, This railway line

1120-1963: Is one suburban rail called the Chittagong Circular Railway . Another suburban railway called the Dhaka Circular Railway is currently proposed. Karachi in Pakistan has a circular railway since 1969. Tehran Metro currently operates the Line 5 commuter line between Tehran and Karaj . Turkey has lines connecting Başkentray , İZBAN , Marmaray and Gaziray . Major metropolitan areas in most European countries are usually served by extensive commuter/suburban rail systems. Well-known examples include BG Voz in Belgrade (Serbia), S-Bahn in Germany, Austria and German-speaking areas of Switzerland, Proastiakos in Greece, RER in France and Belgium, Servizio ferroviario suburbano in Italy, Cercanías and Rodalies ( Catalonia ) in Spain, CP Urban Services in Portugal, Esko in Prague and Ostrava (Czech Republic), HÉV in Budapest (Hungary) and DART in Dublin (Ireland). London has multiple commuter rail routes: The Merseyrail network in Liverpool consists of two commuter rail routes powered by third rail, both of which branch out at one end. At

1200-470: Is operationally more like a typical metro system (frequent trains, an emphasis on standing passengers , short station spacings) than it is like commuter rail in other countries. Japanese commuter rail commonly interline with city center subway lines, with commuter rail trains continuing into the subway network, and then out onto different commuter rail systems on the other side of the city. Many Japanese commuter systems operate various stopping patterns to reduce

1280-511: Is owned by the ICF for testing its coaches and trail runs. Later it is converted to passenger traffic. This line started its service at 2003 from Chennai Beach to Anna Nagar West via Royapuram, Villivakkam, and Padi. But the train service have been with drawn at 2007 due to many reasons and never restored till date. Some of the reasons are: Now this line is used by the ICF for trail runs and also used as

1360-526: Is still possible to tell them apart. Some operators, for example Thameslink , focus solely on commuter services. Others, such as Avanti West Coast and LNER , run solely intercity services. Others still, such as GWR and EMR , run a mixture of commuter, regional and intercity services. Some of these operators use different branding for different types of service (for example EMR brands its trains as either "InterCity", "Connect" for London commuter services, and "Regional") but even for those operators that do not,

1440-579: Is used in Australia (Sydney for example) to describe the regional trains operating beyond the boundaries of the suburban services, even though some of these "inter-city" services stop all stations similar to German regional services. In this regard, the German service delineations and naming conventions are clearer and better used for academic purposes. Sometimes high-speed rail can serve daily use of commuters. The Japanese Shinkansen high speed rail system

1520-426: Is widely used in many commuter rail trains to increase capacity in rush hours. Carriages are usually not organized to increase seating capacity (although in some trains at least one carriage would feature more doors to facilitate easier boarding and alighting and bench seats so that they can be folded up during rush hour to provide more standing room) even in the case of commuting longer than 50 km and commuters in

1600-919: The Brisbane ( Queensland Rail 's City network ) and Perth ( Transperth ) systems in Australia, in some systems in Sweden, and on the Genoa-Casella line in Italy. Some countries and regions, including Finland , India, Pakistan, Russia , Brazil and Sri Lanka, as well as San Francisco ( BART ) in the US and Melbourne and Adelaide in Australia, use broad gauge track. Metro rail and rapid transit usually cover smaller inner-urban areas within 12 to 20 km (7 to 12 mi) of city centers, with shorter stop spacing, use rolling stocks with larger standing spaces, lower top speed and higher acceleration, designed for short-distance travel. They also run more frequently, to

1680-769: The Chennai MRTS , also covers over 300 stations and carries more than 2.5 million people daily to different areas in Chennai and its surroundings. Other commuter railways in India include the Hyderabad MMTS , Delhi Suburban Railway , Pune Suburban Railway and Lucknow-Kanpur Suburban Railway . In 2020, Government of India approved Bengaluru Suburban Railway to connect Bengaluru and its suburbs. It will be unique and first of its kind in India as it will have metro like facilities and rolling stock. In Bangladesh, there

(along GST Road from St. Thomas Mount to Chengalpattu) Chennai city region stations: Chennai Beach – Chennai Fort – Chennai Park – Chennai Egmore – Chetpet – Nungambakkam – Kodambakkam – Mambalam – Saidapet – Guindy – St. Thomas Mount – Pazhavanthangal – Meenambakkam – Tirisulam – Pallavaram – Chromepet – Tambaram Sanatorium – Tambaram – Perungalathur – Vandalur . Stations outside Chennai city regions below: Urapakkam – Guduvancheri – Potheri – Kattangulathur – Maraimalai Nagar – Singaperumal Koil – Paranur – Chengalpattu Stations in

5200-488: The same right-of-way can drastically reduce system construction costs. However, frequently they are built with dedicated tracks within that right-of-way to prevent delays, especially where service densities have converged in the inner parts of the network. Most such trains run on the local standard gauge track. Some systems may run on a narrower or broader gauge. Examples of narrow gauge systems are found in Japan, Indonesia , Malaysia , Thailand , Taiwan, Switzerland, in

5280-455: The same year, mainline DC locomotives (YCG) were introduced to haul freight from the port. The system had the meter-gauge (MG) EMUs (YAU series) until the gauge conversion. Since then, the system has only the broad-gauge (BG) EMUs running. In the 1960s, the line from Madras Beach to Villupuram was converted to 25 kV AC traction. This began with the conversion of the Madras Beach–Tambaram section on 15 January 1967. The rolling stock

5360-516: The southern suburb of Tambaram to run services using steam locomotives . In early 1930, however, the government decided to electrify the lines, including the mainline starting from Egmore . The plan to electrify railway lines in Madras was first initiated in 1923 by Sir Percy Rothera, an agent of the South Indian Railways. This was on account of the city's rapid expansion, with largely agricultural areas such as Saidapet , St. Thomas Mount and Tambaram developing into residential quarters. Plan to build

5440-411: The suburban section have bicycle stands. Chennai has a fairly extensive suburban electric multiple unit (EMU) service. It was in the 1920s that the then British government felt the necessity of connecting the northern part of the city, which was mainly commercial, with the chiefly residential southwestern parts. In 1928, work began on constructing two meter gauge (MG) lines connecting the harbour with

5520-453: The third one was used for mainline express and passenger trains. The newly laid BG line started handling suburban trains supplementing the MG suburban lines. In 1998, further to the Chengleput–Villupuram–Tiruchirapalli gauge conversion project, the railway decided to convert one of the MG lines in the section between Tambaram and Chengleput. However, the decision was soon changed due to large-scale protests by suburban commuters. This resulted in

5600-461: The towns closer to Kowloon. They use rolling stocks with a faster maximum speed and have longer stop spacing compared to other lines which only run in the inner urban area, but in order to maximise capacity and throughput, these rolling stocks have longitudinal seatings, 5 pairs of doors in each carriage with large standing spaces like the urban lines, and run as frequent as well. Most of the sections of these four lines are overground and some sections of

5680-515: The train from either end. The motive power for locomotive-hauled commuter trains may be either electric or diesel–electric , although some countries, such as Germany and some of the former Soviet-bloc countries, also use diesel–hydraulic locomotives. In the US and some other countries, a three-and-two seat plan is used. Middle seats on these trains are often less popular because passengers feel crowded and uncomfortable. In Japan, South Korea and Indonesia, longitudinal (sideways window-lining) seating

5760-553: The trains can be full with commuters standing. The Athens Suburban Railway in Greece consists of five lines, 4 of which are electrified. The Kiato – Piraeus line and the Aigio – Airport lines reach speeds of up to 180 km/h (112 mph). The Athens – Chalcis line is also expected to attain speeds of up to 200 km/h (124 mph) upon upgrading of the SKA–Oinoi railway sector. These lines also have many daily commuters, with

5840-521: The trains run between two or several cities (e.g. S-Bahn in the Ruhr area of Germany). Distances between stations may vary, but are usually much longer than those of urban rail systems. In city centres the train either has a terminal station or passes through the city centre with notably fewer station stops than those of urban rail systems. Toilets are often available on-board trains and in stations. Their ability to coexist with freight or intercity services in

5920-469: The travel time to distant locations, often using station passing loops instead of dedicated express tracks. It is notable that the larger Japanese commuter rail systems are owned and operated by for-profit private railway companies, without public subsidy. East Japan Railway Company operates a large suburban train network in Tokyo with various lines connecting the suburban areas to the city center. While

6000-574: The type of train, amenities offered, and stopping pattern, usually tell the services apart. Russian commuter trains , on the other hand, frequently cover areas larger than Belgium itself, although these are still short distances by Russian standards. They have a different ticketing system from long-distance trains, and in major cities they often operate from a separate section of the train station. Some consider "inter-city" service to be that which operates as an express service between two main city stations, bypassing intermediate stations. However, this term

6080-470: The way inter-city rail does. Regional rail operates outside major cities. Unlike Inter-city, it stops at most or all stations between cities. It provides a service between smaller communities along the line that are often byproducts of ribbon developments , and also connects with long-distance services at interchange stations located at junctions, terminals, or larger towns along the line. Alternative names are "local train" or "stopping train". Examples include

6160-618: The world. It was used by several European colonial powers including France, Britain and Germany in their colonies. In Europe, large metre-gauge networks remain in use in Switzerland, Spain and many European towns with urban trams , but most metre-gauge local railways in France , Germany and Belgium closed down in the mid-20th century, although some still remain. With the revival of urban rail transport, metre-gauge light metros were built in some cities. The slightly-wider 1,009 mm ( 3 ft  3 + 23 ⁄ 32  in ) gauge

6240-515: Was changed to EMUs with motors and electricals from Toshiba or Hitachi . These were built by the Integral Coach Factory based in the city. Services too were extended to Chengleput with two daily services. In the late 1967, a Toshiba/Hitachi/ Mitsubishi combine model YAM-1 21904 locomotive was introduced, which became the first MG 25 kV AC locomotive. Work on additional MG track between Tambaram and Chengleput began in 1969 and

6320-510: Was completed in January 1971. In 1986 or 1987, suburban services to northern and western parts of the city began from the newly built Moore market terminal exclusively built for suburban services, which were earlier operating from the central station terminal (First BG Suburban Services in Chennai). With the growth in suburban traffic and the existing gauge lacking sufficient carrying capacity,

6400-491: Was launched by Sir George Fredrick Stanley , the then governor of Madras, who at the opening ceremony was reported to have said that the new train services would transform "desolate south Madras into burgeoning garden cities". However, the suburban services were opened to the public only a month later on 11 May 1931. The section was electrified on 15 November 1931, with the first MG EMU services running on 1.5 kV DC. The Madras Electricity Supply Corporation, which powered
