Currently there are not many examples of commuter rail in [[Africa]]. [[Metrorail (South Africa)|Metrorail]] operates in the major cities of [[South Africa]], and there are some commuter rail services in [[Algeria]], [[Botswana]], [[Kenya]], [[Morocco]], [[Egypt]] and [[Tunisia]].
In Algeria, [[SNTF]] operates commuter rail lines between the capital [[Algiers]] and its southern and eastern suburbs. They also serve to connect [[Algiers]]' main [[University of Science and Technology, Houari Boumediene|universities]] to each other. The [[Dar es Salaam commuter rail]] offers intracity services in [[Dar es Salaam]], Tanzania. In Botswana, the ([[Botswana Railways]]) "BR Express" has a commuter train between [[Lobatse]] and [[Gaborone]].

[[File:Series-E235-0_9.jpg|thumb|right|An [[E235 series]] train operating a through service on the [[JR East]] [[Yamanote Line]], an example of high-density commuter rail in Japan.]]
In Japan, commuter rail systems have extensive network and frequent service and are heavily used. In many cases, Japanese commuter rail is operationally more like a typical metro system (frequent trains, an emphasis on [[standing passenger]]s, 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 the travel time to distant locations, often using station [[Passing loop|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 the [[Yamanote Line]], [[Keihin Tohoku Line]], [[Chūō–Sōbu Line]] services arguably are more akin to [[rapid transit]] with frequent stops, simple stopping patterns (relative to other JR East lines) no branching services and largely serving the inner suburbs; other services along the [[Chūō Line (Rapid)|Chūō Rapid Line]], [[Sōbu Line (Rapid)|Sōbu Rapid Line]]/[[Yokosuka Line]], [[Ueno–Tokyo Line]], [[Shōnan–Shinjuku Line]] etc. are mid-distance services from suburban lines in the outer reaches of Greater Tokyo through operating into these lines to form a high frequency corridor though central Tokyo.

Other commuter rail routes in Japan include:
* [[Hanshin Namba Line]] and [[Nara Line (Kintetsu)#Kintetsu Namba Line|Kintetsu Namba Line]] have a busy east west underground section that allow trains from both [[Hanshin Electric Railway]] and [[Kintetsu Railway]] to access [[Namba]], a major commercial center of Osaka, and service destinations east and west of Osaka.
* [[Osaka Metro]] [[Sakaisuji Line]] is a north south line that allows [[Hankyu]] services from the [[Hankyu Senri Line|Senri Line]], [[Hankyu Kyoto Main Line|Kyoto Main Line]] and [[Hankyu Arashiyama Line|Arashiyama Line]] to enter Osaka city center.
* [[JR West]] [[Tozai Line (JR West)|Tozai Line]] is an underground east west corridor allowing trains from the [[JR Kobe Line|Kobe Line]], [[JR Takarazuka Line|Takarazuka Line]] and [[Gakkentoshi Line]] to access [[Umeda]] in central Osaka.
*JR West [[Osaka Loop Line]] is a mostly elevated loop line that allows for services from the [[Yamatoji Line]], [[Hanwa Line]] and [[Sakurajima Line]] to loop around central Osaka.
*JR West [[JR Kobe Line|Kobe Line]]/[[JR Kyoto Line|Kyoto Line]] is a four track corridor allowing [[Biwako Line]], [[Kosei Line]], [[JR Takarazuka Line|Takarazuka Line]], [[San'yō Main Line]] and [[Akō Line]] services to service [[Kyoto]], [[Osaka]] and [[Kobe]].
*A special private railway [[Kōbe Rapid Transit Railway]] owns two underground corridors (a north south and east west line) that allow for [[Sanyo Electric Railway]], [[Hankyu|Hankyu railway]], [[Hanshin Electric Railway]] and [[Kobe Electric Railway]] services to enter and cross Kobe city center.
* Most of the trains on the [[Meitetsu]] network through operate into a high frequency trunk line on the [[Meitetsu Nagoya Main Line]] branching out to other lines on the other side of [[Nagoya]].

Commuter rail systems have been inaugurated in several cities in China such as [[Beijing Suburban Railway|Beijing]], [[Shanghai Suburban Railway|Shanghai]], [[Central Plain Metropolitan Intercity Rail|Zhengzhou]], [[Wuhan Metropolitan Area Intercity Railway|Wuhan]], [[Changsha–Zhuzhou–Xiangtan Intercity Railway|Changsha]] and the [[Pearl River Delta Rapid Transit|Pearl River Delta]]. With plans for large systems in northeastern [[Zhejiang]], [[Jingjinji]], and [[Yangtze River Delta]] areas. The level of service varies considerably from line to line ranging [[high speed rail|high]] to near high speeds. More developed and established lines such as the [[Guangzhou–Shenzhen Railway|Guangshen Railway]] have more frequent metro-like service. 

The two [[MTR]] lines which are owned and formerly operated by the [[Kowloon-Canton Railway Corporation]] ([[East Rail line]] and [[Tuen Ma line]] which is integrated from the former [[West Rail line]] and [[Ma On Shan line]] in 2021), then the [[Kowloon–Canton Railway|"KCR"]]), and MTR's own [[Tung Chung line]] connect the new towns in [[New Territories]] and the city centre [[Kowloon]] together with frequent intervals, and some New Territories-bound trains terminate at intermediate stations, providing more frequent services in Kowloon and 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 the East Rail Line share tracks with intercity trains to [[mainland China]]. The three KCR lines are integrated into the MTR network since 2008 and most passengers do not need to exit and re-enter the system through separate fare gates and purchase separate tickets to transfer between such lines and the rest of the network (the exceptions are between the Tuen Ma line's [[East Tsim Sha Tsui station]] and the Tsuen Wan line's [[Tsim Sha Tsui station]].

In Taiwan, the [[Western Trunk line|Western line]] in the [[Taipei]]-[[Taoyuan City|Taoyuan]] Metropolitan Area, [[Taichung]] Metropolitan Area and [[Tainan]]-[[Kaohsiung]] Metropolitan Area as well as the [[Neiwan line|Neiwan]]-[[Liujia line]] in the [[Hsinchu]] Area are considered commuter rail.

In South Korea, the [[Seoul Metropolitan Subway]] includes a total of 22 lines, and some of its lines are suburban lines. This 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 the dense parts of Seoul, some track sections extend far outside of the city, and operate large sections at ground level, such as on the [[Seoul Subway Line 1|Line 1]], [[Seoul Subway Line 3|Line 3]] and [[Seoul Subway Line 4|Line 4]]. In Busan, the [[Donghae Line]], while part of the [[Busan Metro]] system, mostly functions as a commuter rail line.

[[File:KRL6000Kebayoran.jpg|thumb|right|The [[KRL Commuterline]] set [[Tokyo Metro 6000 series|6000 series]] serves the [[Rangkasbitung Line]] in Indonesia]]

In [[Indonesia]], the [[KRL Commuterline]] is the largest commuter rail system in the country, serving the [[Jakarta metropolitan area|Greater Jakarta]]. It connects the [[Jakarta]] city center with surrounding cities and sub-urbans in [[Banten]] and [[West Java]] provinces, including [[Depok]], [[Bogor]], [[Tangerang]],  [[Serpong]], [[Rangkasbitung]], [[Bekasi]] and [[Cikarang]]. In July 2015, KRL Commuterline served more than 850,000 passengers per day, which is almost triple of the 2011 figures, but still less than 3.5% of all Jabodetabek commutes.<ref>{{cite web |url=http://megapolitan.kompas.com/read/2015/07/06/14142481/PT.KCJ.Keterlambatan.KRL.Sudah.di.Bawah.10.Menit |title=PT KCJ: Keterlambatan KRL Sudah di Bawah 10 Menit |work=KOMPAS.com |date=July 6, 2015 |last1=Media |first1=Kompas Cyber }}</ref> Other commuter rail systems in Indonesia include the [[Metro Surabaya Commuter Line]], [[KAI Commuter Line Bandung|Commuter Line Bandung]], [[KAI Commuter Yogyakarta Line|KAI Commuter Yogyakarta–Solo Line]], [[Kedungsepur (train)|Kedung Sepur]], and the [[Sri Lelawangsa]].

In the Philippines, the [[Philippine National Railways]] has two commuter rail systems currently operational; the [[PNR Metro Commuter Line]] in the [[Greater Manila Area]] and the [[PNR Bicol Commuter]] in the [[Bicol Region]]. A new commuter rail line in Metro Manila, the [[North–South Commuter Railway]], is currently under construction. Its North section is set to be partially opened by 2021.

In Malaysia, there are two commuter services operated by [[Keretapi Tanah Melayu]]. They are the [[KTM Komuter]] that serves [[Kuala Lumpur]] and the surrounding [[Klang Valley|Klang Valley area]], and the [[KTM Komuter Northern Sector]] that serves the [[George Town Conurbation]], [[Perak]], [[Kedah]] and [[Perlis]] in the northern region of Peninsular Malaysia.

In Thailand, the [[Greater Bangkok Commuter rail]] and the [[Airport Rail Link (Bangkok)|Airport Rail Link]] serve the [[Bangkok Metropolitan Region]]. The [[SRT Red Lines]], a new commuter line in Bangkok, started construction in 2009. It opened in 2021.

Another commuter rail system in Southeast Asia is the [[Yangon Circular Railway]] in [[Myanmar]].

[[File:ChennaiEMUNew.JPG|thumb|220x220px|Chennai suburban railway]]
[[File:KolkataLocalTrains.JPG|thumb|220x220px|[[Kolkata Suburban Railway]] is the largest suburban railway network in India. ]]
In India, commuter rail systems are present in major cities and form an important part of people's daily lives. [[Mumbai Suburban Railway]], the oldest suburban rail system in Asia, carries more than 7.24 million commuters on a daily basis which constitutes more than half of the total daily passenger capacity of the Indian Railways itself. [[Kolkata Suburban Railway]], one of the largest suburban railway networks in the world, consists of more than 450 stations and carries more than 3.5 million commuters per day. The [[Chennai Suburban Railway]] along with 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 Commuter Rail|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 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 [[Karachi Circular Railway|circular railway]] since 1969.

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, [[Réseau Express Régional|RER]] in France and Belgium, Servizio ferroviario suburbano in Italy, [[Cercanías]] and [[Rodalies de Catalunya|Rodalies]] ([[Catalonia]]) in Spain, [[CP Urban Services]] in Portugal, [[Esko Prague|Esko]] in [[Prague]] and [[Ostrava]] (Czech Republic), [[HÉV]] in [[Budapest]] (Hungary) and [[Dublin Area Rapid Transit|DART]] in [[Dublin]] (Ireland).

[[London]] has multiple commuter rail routes:
* The [[Elizabeth line]] runs on a {{convert|22|km|abbr=off|adj=on}} east–west twin tunnel under central London ([[Crossrail]] project) as its central core section.
* [[Thameslink]] brings together several branches from northern and southern suburbs and satellite towns in to a high frequency central tunnel underneath London.
* The [[London Overground]], by contrast, skirts through the inner suburbs with lines mostly independent of each other, although there are several branches. The [[Watford DC line]], partly shared with underground trains, uses third rail, but parallels a main line using overhead wires. The [[East London line]] and [[North London line]] run at metro-like frequencies in inner London, which make them nearly indistinguishable from metro systems apart from the fact that the tracks are shared with freight trains.
* The [[Metropolitan line]], despite being part of the [[London Underground]], is a commuter rail route as it links the [[City of London]] to commuter towns outside [[Greater London]] such as [[Rickmansworth]], [[Amersham]] and [[Chesham]], where it runs to a timetable, being the only [[London Underground]] line with a public timetable published. It also shares tracks with [[Chiltern Railways]] main line services between London and [[Aylesbury]].

The [[Merseyrail]] network in [[Liverpool]] consists of two commuter rail routes powered by third rail, both of which branch out at one end. At the other, the [[Northern line (Merseyrail)|Northern line]] continues out of the city centre to a mainline rail interchange, while the [[Wirral line]] has a city-centre loop.

[[Birmingham]] has four suburban routes which operate out of [[Birmingham New Street]] & [[Birmingham Moor Street]] stations, one of which is operated using diesel trains.

The [[Tyneside Electrics]] system in [[Newcastle upon Tyne]] existed from 1904 to 1967 using DC third rail. [[British Rail]] did not have the budget to maintain the ageing electrification system. The [[Riverside Branch]] was closed, while the remaining lines were de-electrified. 13 years later, they were re-electrified using DC overhead wires, and now form the [[Tyne & Wear Metro]] Yellow Line.

Many of the rail services around [[Glasgow]] are branded as [[Strathclyde Partnership for Transport]]. The network includes most electrified Scottish rail routes.

The [[West Yorkshire Passenger Transport Executive]] run eleven services which feed into Leeds, connecting the city with commuter areas and neighbouring urban centres in the [[West Yorkshire Built-up Area]].

[[MetroWest (Bristol)|MetroWest]] is a proposed network in [[Bristol]], northern [[Somerset]] & southern [[Gloucestershire]]. The four-tracking of the line between [[Bristol Temple Meads railway station|Bristol Temple Meads]] and [[Bristol Parkway railway station|Bristol Parkway]] stations will enable local rail services to be separated from long-distance trains.

The [[Réseau Express Régional|Réseau express régional d'Île-de-France]] (RER) is a commuter rail network in the agglomeration of [[Paris]]. In the centre the RER has high frequency underground corridors where several suburban branches feed similar to a [[rapid transit]] system.

Commuter rail systems in [[German language|German-speaking regions]] are called [[S-Bahn]]. While in some major cities S-Bahn services run on separate lines exclusively other systems use the existing regional rail tracks.

[[Randstadspoor]] is a network of [[Nederlandse Spoorwegen#Types of train service|Sprinter]] train services in and around the city of [[Utrecht]] in the Netherlands. For the realisation of this network, new stations were opened. Separate tracks have been built for these trains, so they can call frequently without disturbing high-frequent Intercity services parallel to these routes.<ref>{{cite web|url=https://www.provincie-utrecht.nl/onderwerpen/mobiliteit/spoorprojecten#randstadspoor|title=Spoorprojecten|publisher=Provincie Utrecht|access-date=2021-02-09}}</ref> Similar systems are planned for [[The Hague]] and [[Rotterdam]].

====Northern Europe====
In Sweden, electrified commuter rail systems known as ''Pendeltåg'' are present in the cities of [[Stockholm]] and [[Gothenburg]]. The [[Stockholm commuter rail]] system, which began in 1968, shares railway tracks with inter-city trains and freight trains, but for the most part runs on its own dedicated tracks. It is primarily used to transport passengers from nearby towns and other suburban areas into the city centre, not for transportation inside the city centre. The [[Gothenburg commuter rail]] system, which began in 1960, is similar to the Stockholm system, but does fully share tracks with long-distance trains.

In Norway, the [[Oslo Commuter Rail|Oslo commuter rail]] system is from 2022 more limited but the remaining commuter lines go on tracks mostly not much used by other trains. From 2022 several lines with hourly frequency and travel times to endpoints of over one hour are redefined as regional trains. Before 2022 Oslo had the largest commuter rail system in the Nordic countries in terms of line lengths and number of stations. Also [[Bergen Commuter Rail|Bergen]], [[Jæren Commuter Rail|Stavanger]] and [[Trønderbanen|Trondheim]] have commuter rail systems. These have only one or two lines each and they share tracks with other trains.

In [[Finland]], the [[Helsinki commuter rail]] network runs on dedicated tracks from [[Helsinki Central railway station]] to [[Leppävaara railway station|Leppävaara]] and [[Kerava]]. The [[Ring Rail Line]] serves [[Helsinki Airport]] and northern suburbs of [[Vantaa]] and is exclusively used by the commuter rail network. On 15 December 2019, the [[Tampere]] region got its own commuter rail service, with trains running from Tampere to [[Nokia, Finland|Nokia]], [[Lempäälä]] and [[Orivesi]].

====Southern Europe====
In [[Spain]], ''[[Cercanías]]'' networks exist in [[Cercanías Madrid|Madrid]], [[Cercanías Sevilla|Sevilla]], [[Cercanías Murcia/Alicante|Murcia/Alicante]], [[Cercanías San Sebastián|San Sebastián]], [[Cercanías Cádiz|Cádiz]], [[Cercanías Valencia|Valencia]], [[Cercanías Asturias|Asturias]], Santander, [[Cercanías Zaragoza|Zaragoza]], [[Cercanías Bilbao|Bilbao]] and [[Cercanías Málaga|Málaga]]. All these systems include underground sections in the city centre. There is also a network of [[Metre-gauge railway|narrow-gauge]] [[Renfe Feve|commuter systems]] in North Spain and Murcia.
[[File:Cercanías Madrid Atocha 2008.jpg|thumb|Atocha is the main station in Spain mainly due to the Cercanías.]]
[[Cercanías Madrid]] is one of the most important train services in the country, more than 900,000 passengers move in the system. It has underground stations in Madrid like [[Recoletos Station|Recoletos]], [[Sol (Madrid Metro)|Sol]] or [[Nuevos Ministerios (Madrid Metro)|Nuevos Ministerios]] and in the [[Madrid metropolitan area|metropolitan area]] in cities like [[Parla]] or [[Getafe]].

====Eastern Europe====
[[File:SKM S9 Pludy.JPG|thumb|[[Szybka Kolej Miejska (Warsaw)|SKM]] train in Warsaw, Poland]]
In Poland, commuter rail systems exist in [[Szybka Kolej Miejska (Tricity)|Tricity]], [[Szybka Kolej Miejska (Warsaw)|Warsaw]], [[Kraków]] ([[Szybka Kolej Aglomeracyjna|SKA]]) and [[Katowice]] ([[Szybka Kolej Regionalna|SKR]]). There is also a similar system planned in [[Wrocław]] and [[Szczecin]].<ref>{{cite web|title=Szczecińska Kolej Metropolitalna -|url=http://skm.szczecin.pl/index.php}}</ref> The terms used are "Szybka Kolej Miejska" (fast urban rail) and "kolej aglomeracyjna" (agglomeration rail). These systems are:
* [[Szybka Kolej Miejska (Warsaw)|Szybka Kolej Miejska w Warszawie]] in the [[Warsaw]] urban area, with 4 lines and 46 stations.<ref>[[:pl:Szybka Kolej Miejska w Warszawie]]</ref>{{Circular reference|date=May 2020}}
* [[Łódzka Kolej Aglomeracyjna]] is located in the center of Poland connecting satellite towns in and around [[Łódź]]. It also operates some trains between Łódź and Warsaw.
*[[Szybka Kolej Miejska (Tricity)|Szybka Kolej Miejska w Trójmieście]] is located in the [[Tricity, Poland|Tricity]]/Trójmiasto urban area, the three cities of [[Gdańsk]], [[Gdynia]] and [[Sopot]].

The [[Proastiakos]] ({{langx|el|Προαστιακός}}; "suburban") is [[Greece]]'s [[suburban]] railway (commuter rail) services, which are run by [[TrainOSE]], on infrastructure owned by the [[Hellenic Railways Organisation]] (OSE). There are three Proastiakos networks, servicing the country's three largest cities: [[Athens]], [[Thessaloniki]] and [[Patras]]. In particular, the [[Athens Suburban Railway|Athenian network]] is undergoing modifications to completely separate it from mainline traffic, by re-routing the tracks via a tunnel underneath the city center. A similar project is planned for the [[Patras]] network, whereas a new line is due to be constructed for the [[Thessaloniki Regional Railway|Thessalonian network]].

In Romania, the first commuter trains were introduced in December 2019. They operate between [[Bucharest]] and Funduea or [[Buftea]].

[[BG Voz]] is an urban rail system that serves Belgrade. It currently has only two routes, with plans for further expansion. Between the early 1990s and mid-2010s, there was another system, known as [[Beovoz]], that was used to provide [[mass-transit]] service within the Belgrade [[metropolitan area]], as well as to nearby towns, similarly to [[Réseau Express Régional|RER]] in Paris. Beovoz had more lines and far more stops than the current system. However, it was abandoned in favor of more accurate BG Voz, mostly due to inefficiency. While current services rely mostly on the existing infrastructure, any further development means furthering capacities (railways expansion and new trains). Plans for further extension of system include another two lines, one of which should reach [[Belgrade Nikola Tesla Airport]].

In Russia, Ukraine and some other countries of the former [[Soviet Union]], electrical multiple unit passenger suburban trains called [[Elektrichka]] are widespread. The first such system in Russia is the Oranienbaum Electric Line in [[Saint Petersburg|St. Petersburg]]. In Moscow the Beskudnikovskaya railway branch existed between the 1940s and 1980s. The trains that shuttled along it did not go to the main lines, so it was a city transport. Today there are the [[Moscow Central Circle]] and the [[Moscow Central Diameters]].

{{Main|Commuter rail in North America}}
In the United States, Canada, Costa Rica, El Salvador and Mexico regional passenger rail services are provided by governmental or quasi-governmental agencies, with the busiest and most expansive rail networks located in the Northeastern US, California, and Eastern Canada. Most North American commuter railways utilize [[diesel locomotive]] propulsion, with the exception of services in New York City, Philadelphia, Chicago, Denver, San Francisco, and Mexico City; New York's commuter rail lines use a combination of third rail and overhead wire power generation, while Chicago only has two out of twelve services that are electrified. Many newer and proposed systems in Canada and the United States are often are geared to serving peak-hour commutes as opposed to the all-day systems of Europe, East Asia, and Australia.

The five major cities in Australia have suburban railway systems in their metropolitan areas. These networks have frequent services, with frequencies varying from every 10 to every 30 minutes on most suburban lines, and up to 3–5 minutes in peak on bundled underground lines in the city centres of Sydney, Brisbane, Perth and Melbourne. The networks in each state developed from mainline railways and have never been completely operationally separate from long distance and freight traffic, unlike [[Rapid transit|metro]] systems. The suburban networks are almost completely electrified.

The main suburban rail networks in Australia are:
* The [[Sydney Trains]] suburban rail network consists of nine lines converging in the underground [[City Circle]] with frequencies as high as three minutes in this section, 5–10 minutes at most major stations all day and 15 minutes at most minor stations all day.
*The [[Railways in Sydney|Sydney rail network]] operated by [[Sydney Trains]] in [[Sydney]] (with connected suburban services in [[Newcastle, New South Wales|Newcastle]] and [[Wollongong]] run by its counterpart intercity operator, [[NSW TrainLink]]).

* [[Railways in Melbourne|Melbourne's rail network]] features sixteen electrified commuter rail lines traversing the city centre in the underground [[City Loop]] providing a metro-like service in the central core. A second underground core is under construction, as the [[Metro Tunnel]] project. [[V/Line]] operates some commuter services between Melbourne and surrounding towns, as well as between Melbourne and some locations within the Melbourne metropolitan area.

* Commuter rail services in [[Brisbane]] are provided under the [[Queensland Rail City network]] brand, featuring twelve electrified lines converging in the city centre. [[Cross River Rail]] is an under construction underground cross-city tunnel to relieve pressure on this network.

* [[Railways in Perth]] fall under the [[Transperth]] network, which are operated by the [[Public Transport Authority (Western Australia)|Public Transport Authority]]

*The [[Railways in Adelaide|Adelaide rail network]] operated by [[Adelaide Metro]] in [[Adelaide]].

New Zealand has two frequent suburban rail services comparable to those in Australia: the [[Public transport in Auckland|Auckland rail network]] is operated by [[Auckland One Rail]] and the [[Public transport in the Wellington Region|Wellington rail network]] is operated by [[Transdev Wellington]].
