TheInfoList




The S-train is a type of hybrid urban rail, urban-suburban rail serving a metropolitan region. Some of the larger S-train systems provide service similar to rapid transit systems, while smaller ones often resemble Commuter rail, commuter or even regional rail. They are especially common in Germany and Austria, where they are known as S-Bahn, which in the 1930s was an abbreviation of either ''Schnellbahn'', ''Stadtbahn'' or ''Stadtschnellbahn'', depending on the city, but they must not be confused with ''U-Stadtbahnen''. Similar S-train systems exist also in Switzerland known as S-Bahn as well. In Denmark, they are known as S-tog , in the Czech Republic as Esko or S-lines, and northern Italy as Servizio ferroviario followed by either the word "metropolitano" (in Turin) or "suburbano" (in Milan).


Characteristics

There is no complete definition of an S-train system. S-trains are, where they exist, the most local type of railway stopping at all existing stations inside and around a city, while other mainline trains only call at major stations. They are slower than mainline railways but usually serve as fast crosstown services within the city. The S-train (Copenhagen), Copenhagen S-tog for example goes up to , faster than most urban heavy rail and mass transit. S-trains generally service the hinterland of a certain city, rather than connecting different cities, although in high population density areas a few exceptions from this exist. A good example of such an exception is the Rhine-Ruhr S-Bahn, which interconnects the cities, towns and suburbs of the Ruhr, a large urban agglomeration, not unlike the large network of regional trains which also serve the area. Most S-train systems are entirely built on older local railways, or in some cases parallel to an existing dual track railway. Most use existing local mainline railway trackage, but a few branches and lines can be purpose-built S-train lines. S-trains typically use overhead lines or a third rail for traction power. In Hamburg the S-trains use both the methods, depending on which line is powered. In smaller S-train systems and suburban sections of larger ones, S-trains typically share tracks with other rail traffic, with the Berlin S-Bahn, Hamburg S-Bahn and Copenhagen S-train being notable exceptions. Busy S-train corridors sometimes have sections of exclusive trackage of their own but parallel to mainline railways. Many of the larger S-train systems will also have central corridors of exclusive trackage that individual suburban branches feed into, creating a high frequency trunk corridor. In many cases, the central corridor is a dedicated underground line in the city centre with close stop spacing and a high frequency, similar to metro systems, created from the combined interlining of the multiple branches. A good example of this is the Berliner Stadtbahn in the Berlin's S-Bahn, which is regarded as a tourist attraction. However, in more lightly used sections outside the city centre, S-trains commonly share tracks with other train types. Further out from the central parts of a city the individual services branch off into lines where the distances between stations can exceed 5 km, similar to commuter rail. This allows the S-train to serve a dual transport purpose: local transport within a city centre and suburban transport between central boroughs of larger cities, and to suburbs. Frequencies vary wildly between systems with short headways in the core sections of large networks to headways of over 20 minutes in remote sections of the network, late at night and/or on Sundays and in smaller systems. The rolling stock typically used in S-trains reflect its hybrid purpose. The interior is designed for short journeys with provision for standing passengers but may have more space allocated to larger and more numerous seats. Integration with other local transport for ticketing, connectivity and easy interchange between lines or other system like metros is typical for S-trains. Where both S-train and metro exist, the number of interchange stations between the two systems is substantial with metro tickets being valid on S-trains, and vice versa. The S-Bahn Mitteldeutschland constitutes the main local railway system for Leipzig but also connects to Halle (Saale), Halle, where a few stations are located. The Rostock S-Bahn is an example of a smaller S-Bahn system.


Etymology


Germany, Austria and Switzerland

The name ''S-Bahn'' (S-train) is an abbreviation for the German "Stadtschnellbahn" (meaning "city rapid railway") and was introduced in December 1930 in Berlin. The name was introduced at the time of the reconstruction of the suburban commuter train tracks— the first section to be electrified was a section of the Berlin–Szczecin railway from Berlin Nordbahnhof to Bernau bei Berlin station in 1924, leading to the formation of the Berlin S-Bahn. The main line Berlin Stadtbahn (English: ''City railway of Berlin'') was electrified with a 750 volt third rail in 1928 (some steam trains ran until 1929) and the circle line Berlin Ringbahn was electrified in 1929. The electrification continued on the radial suburban railway tracks along with changing the timetable of the train system into a rapid transit model with no more than 20 minutes headway per line where a number of lines overlapped on the main line. The system peaked during the 1936 Summer Olympics in Berlin to a train schedule below 2 minutes. The idea of heavy rail rapid transit was not unique to Berlin. Hamburg had an electric railway between the central station ("Hauptbahnhof") and Altona which opened in 1906 and in 1934 the system adopted the S-Bahn label from Berlin. The same year in Denmark, Copenhagen's S-tog opened its first line. In Austria, Vienna had its ''Stadtbahn'' main line electrified in 1908 and also introduced the term ''Schnellbahn'' ("rapid railway") in 1954 for its planned commuter railway network (which started operations in 1962). The S-Bahn label was sometimes used as well, but the name was only switched to S-Bahn Wien in 2005. As for Munich, a first breaking ground for an S-train-like rapid transport system, executed by the Nazi government of Adolf Hitler, took place in 1938 in Lindwurmstrasse near what is now Goetheplatz underground station (line U6). Said system was supposed to run through tunnels in downtown areas. The planning process mainly consisted of the bundling and interconnecting of existing suburban and local railways, plus the construction of a few new lines. Plans and construction work - including the building shell of Goetheplatz station - came to a very early halt during World War II and were not pursued in its aftermath. Very extensive nowadays, Munich's existing S-Bahn-System, together with the first two U-Bahn lines, began to operate prior to the 1972 Summer Olympics only. The term ''S-Bahn'' was until 14 March 2012 a registered wordmark of Deutsche Bahn, where at the request of a transportation association the Federal Patent Court of Germany ordered the wordmark to be removed from the records of the Deutsches Patent- und Markenamt, German Patent and Trade Mark Office. Prior to the said event Deutsche Bahn collected a royalty of 0.4 cents per train kilometer for the usage of the said term.


Denmark

The "S" stood for "station". Just before the opening of the first line in the Copenhagen S-train network, the newspaper ''Politiken'' on 17 February 1934 held a competition about the name, which in Danish became known as ''Den elektriske enquete'' or "The electrical survey" (as the Copenhagen S-trains would become the first electrical railways in Denmark). But since an "S" already was put up at all the stations, weeks before the survey, the result became ''S-tog'' which means "S-train".John Poulsen: S-bane 1934-2009 side 47 This was also just a few years after the S-trains had opened in Berlin and Hamburg. Today the Copenhagen S-trains uses six lines and serves 85 stations, 32 of them are located inside the (quite tiny) municipality borders. Each line uses 6 t.p.h (trains per hour) in each direction, with exception of the (yellow) F-line. The F-line has departures in each direction every five minutes, or 12 t.p.h. service .


History


Germany


Early steam services

In 1882, the growing number of Steam locomotive, steam-powered trains around Berlin prompted the Prussian State Railway to construct separate rail tracks for suburban traffic. The ''Berliner Stadtbahn'' connected Berlin's eight intercity rail stations which were spread throughout the city (all but the ''Stettiner Bahnhof'' which today is a pure S-train station known as Berlin Nordbahnhof; as the city ''Stettin'' today is Polish city Szczecin). A lower rate for the newly founded ''Berliner Stadt-, Ring- und Vorortbahn'' (Berlin City, Circular and Suburban Rail) was introduced on 1 October 1891. This rate and the growing succession of trains made the short-distance service stand out from other railways. The second suburban railway was the ''Hamburg-Altonaer Stadt- und Vorortbahn'' connecting Hamburg with Altona, Hamburg, Altona and Blankenese. The Altona office of the Prussian State Railway established the electric powered railway in 1906.See picture of Berliner Stadtbahn by Hackescher Markt S-train station, the third rail is clearly seen between the two S-Train tracks. Original name of that station was "Börse", or "the Stock Market" (which now is located in Frankfurt am Main)


Electricity

The beginning of the 20th century saw the first electric trains, which in Germany operated at 15,000 Volt, V on overhead lines. The ''Berlin S-Bahn, Berliner Stadt-, Ring- und Vorortbahn'' instead implemented direct current multiple units running on 750 V from a third rail. In 1924, the first electrified route went into service. The third rail was chosen because it made both the modifications of the rail tracks (especially in tunnels and under bridges) and the side-by-side use of electric and steam trains easier. To set it apart from the subterranean ''Rapid transit in Germany#U-Bahn, U-Bahn'', the term ''S-Bahn'' replaced ''Stadt-, Ring- und Vorortbahn'' in 1930. The Hamburg service had established an alternating current line in 1907 with the use of multiple units with slam doors. In 1940 a new system with 1200 V DC third rail and modern electric multiple units with sliding doors was integrated on this line (on the same tracks). The old system with overhead wire remained up to 1955. The other lines of the network still used steam and later Diesel power. In 1934, the ''Hamburg-Altonaer Stadt- und Vorortbahn'' was renamed as S-Bahn.


Comparable systems


Australia

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. 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. 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. Transperth Trains operates commuter rail services in the Perth metropolitan area, with the Joondalup railway line and Mandurah railway line operating at metro-like frequencies.


Austria

The oldest and largest S-Bahn system in Austria is the Vienna S-Bahn, which predominantly uses non exclusive rails tracks outside of Vienna. It was established in 1962, although it was usually referred to as ''Schnellbahn'' until 2005. The white "S" on a blue circle used as the logo is said to reflect the layout of the central railway line in Vienna. However, it has now been changed for a more stylized version that is used all through Austria, except Salzburg. The rolling stock was blue for a long time, reflecting the logo colour, but red is used uniformly for nearly all local traffic today. In 2004, the Salzburg S-Bahn went into service as the first Euroregion S-Bahn, crossing the border to the neighbouring towns of Freilassing and Berchtesgaden in Bavaria. The network is served by three corporations: the ''Berchtesgadener Land Bahn'' (BLB)(S4), the Austrian Federal Railways (German: ''Österreichischen Bundesbahn'' / ÖBB)(S2 and S3) and the ''Salzburger Lokalbahn'' (SLB)(S1 and S11) and . The Salzburg S-Bahn logo is only different one, it is a white S on a light blue circle. In 2006 the Regionalbahn, regional train line in the Alpine Rhine, Rhine Valley in the States of Austria, state of Vorarlberg has been renamed to ''S-Bahn Vorarlberg''. It is a three lines network, operated by the ''Montafonerbahn'' and the ÖBB. The ''S-Bahn Steiermark'' has been inaugurated in December 2007 in Styria, built to connect its capital city Graz with the rest of the metropolitan area, currently the following lines are active: S1, S11, S3, S31, S5, S51, S6, S61, S7, S8 and S9. The network is operated by three railway companies: the ''Graz-Köflacher Bahn'' (GKB) (lines: S6, S61 and S7), the ÖBB (lines: S1, S3, S5, S51, S8 and S9) and the ''Steiermärkische Landesbahnen'' (StB) (lines: S11 and S31). In December 2007 as well the Tyrol S-Bahn opened, running from Hall in Tirol in the east to Innsbruck Hauptbahnhof, Innsbruck Central Station and Telfs in the west and from Innsbruck to Steinach am Brenner. Bombardier Talent, Class 4024 Electric multiple unit, EMUs are used as rolling stock on this network. In 2010 the ''S-Bahn Kärnten'' was opened in the States of Austria, state of Carinthia and currently consists of 4 lines operated by ÖBB. The youngest network is the ''S-Bahn Oberösterreich'' in the Greater Linz area of the state of Upper Austria, which was inaugurated in December 2016. It is a 5 line system operated by ''Stern und Hafferl Verkehr, Stern und Hafferl'' and the ÖBB.


Belgium

The suburban railways of Brussels are currently being integrated into the Brussels Regional Express Network (French: ''Réseau Express Régional Bruxellois'', ''RER''; Dutch: ''Gewestelijk ExpresNet'', GEN), which is identified by the letter ''S'' across both languages. In 2018, the S-train was also introduced in Antwerp, Ghent, Liège and Charleroi.


Brazil

In São Paulo, the Companhia Paulista de Trens Metropolitanos suburban rail network operates at high frequencies on tracks used exclusively for commuter traffic. SuperVia provides electrified commuter rail services in Rio de Janeiro.


Czech Republic

In the Czech Republic, integrated commuter rail systems exist in Prague and Moravian-Silesian Region. Both systems are called ''Esko'', which is how ''S'' letter is usually called in Czech. Esko Prague has been operating since 9 December 2007 as a part of the Prague Integrated Transport system. Esko Moravian-Silesian Region began operating on 14 December 2008 as a part of the ODIS Integrated Transport system serving the Moravian-Silesian Region. Both systems are primarily operated by České dráhy. Several shorter lines are operated by other companies.


Denmark

Copenhagen S-train connects the city centre, other inner and outer boroughs and suburbs with each other. The average distance between stations is 2.0 km, shorter in the city core and inner boroughs, longer at the end of lines that serve suburbs. Of the 85 stations, 32 are located within the central parts of the city. Some stations are located around 40 km from Copenhagen city centre. For this reason the fares vary depending on distances. One-day-passes which tourist buy are valid only in the most central parts of the S-train system. Weekdays each line have departures every 10th minute with exception for the F-line, which departures every fifth minute. Where several lines use the same branches, up to around 30 trains per hour (in each direction) service exists. On Sundays the seven lines are reduced to four lines, but all stations are served at least every 10th minute. The three railway stations at Amager have a local service that equals the S-trains'. The Copenhagen Metro opened in 2002 as a complement to the already existing S-train system. Copenhagen's S-train system is the only one in the country. Outside Denmark, in cities where both exist, is it far from unusual that a metro system later has been complemented with S-trains. The branch towards Køge (the southernmost S-train station in Copenhagen's S-network) has a rather unique history, as it was built in the 1970s where no previous railway ever had existed.


Finland

The Helsinki commuter rail network is completely electrified with exclusive tracks running parallel to mainline rail tracks. The Ring Rail Line operates at ten-minute frequencies.


France

The term ''Réseau Express Régional'' (lit. Regional Express Network) originally referred only to the Paris system, but is now used for other French urban rail networks as well. However, only the Réseau Express Régional, Paris RER has high-frequency underground corridors into which several suburban branches feed, and the stop spacing of a rapid-transit system, similar to an S-Train.


Germany

The trains of the Berlin and Hamburg S-Bahn systems ran on separate tracks from the beginning. When other cities started implementing their systems in the 1960s, they mostly had to use the existing intercity rail tracks, and they still more or less use such tracks. The Hauptbahnhof, central intercity stations of Frankfurt (Main) Hauptbahnhof, Frankfurt, Leipzig Hauptbahnhof, Leipzig, München Hauptbahnhof, Munich and Stuttgart Hauptbahnhof, Stuttgart are terminal stations, so all four cities have monocentric S-Bahn networks. The S-Bahn trains use a tunnel under the central station and the city centre. The high number of large cities in the Ruhr area promotes a polycentric network connecting all cities and suburbs. The ''Rhein-Ruhr S-Bahn, S-Bahn Rhein-Ruhr'', as it is called, features few tunnels, and its routes are longer than those of other networks. The Ruhr S-Bahn is the only S-Bahn network to be run by more than one corporation in Germany, and the Salzburg S-Bahn holds a similar distinction in Austria. Most Swiss S-Bahn systems are multi-corporation networks, however. Most German S-Bahn networks have a unique ticket system, separated from the ''Deutsche Bahn'' rates, instead connected to the city ticket system used for U-bahns and local buses. The S-Bahn of Hanover, however, operates under five different rates due to its large expanse. One S-Bahn system is no longer in operation: the Erfurt S-Bahn which operated from 1976 until 1993 and was an single-line system which consisted of four stations from Erfurt Central Station to Erfurt Berliner Straße station in the then newly built northern suburbs of Erfurt. There are several S-Bahn or S-Bahn-like systems in planning, such as the Danube-Iller S-Bahn and the Augsburg S-Bahn. The S-Bahn system in Lübeck is under discussion (see :File:S-Bahn Lübeck.svg, network plan). The Stadtbahn Karlsruhe (a tram-train network) uses the green "S" logo, but does not refer to itself as ''S-Bahn''. The blue ''Rapid transit in Germany#U-Bahn, U-Bahn'' logo is not used either, due to the lack of subterranean lines. Despite their names, the ''Ortenau S-Bahn'' (Offenburg) is a Regionalbahn service. The following networks are currently in operation:


Greece

The Proastiakos ( 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, providing them with commuter rail links towards their suburbs and also with regional services to other cities and towns. In particular, the Proastiakos Athens, Athens network is due to undergo modifications to completely separate it from mainline traffic, by rerouting 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 Proastiakos Thessaloniki, Thessaloniki network.


Hong Kong

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. 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 East Tsim Sha Tsui station and the Tsuen Wan line's Tsim Sha Tsui station, and between the East Rail line's Mong Kok East station and the Kwun Tong line's Mong Kok station).


Hungary


India

S-Bahn-like train services (called Suburban Railway) in the country are commonplace in many cities across India. However, the Suburban Railway systems of Mumbai Suburban Railway, Mumbai and Chennai Suburban Railway, Chennai are the only systems to have exclusive tracks.


Indonesia

KRL Commuterline or Commuter Line Jabodetabek is a commuter railway system serving Jakarta and its satellite cities as well as its regencies. The system currently has 6 lines, 80 stations, and it spans 480 km with roughly 300 million passengers annually. The system only accept bank-issued cards and e-tickets which can be purchased or topped up at any stations throughout the system.


Ireland

Dublin Suburban Rail and Dublin Area Rapid Transit, DART fill the role of an S-train rail service in Dublin, Ireland, although only DART has the common spine running through the city centre that characterises other European S-train networks, although this runs on an elevated track, rather than underground.


Italy

Several systems in Italy operate quite similar to S-Trains with numerous services funneling into the underground "Passante" or passing railway. Operating services in the country are: *Milan suburban railway service, operated by Trenord and Azienda Trasporti Milanesi, ATM has numerous services funneling into the underground Milan Passante railway. *Turin metropolitan railway service, operated by Ferrovie Regione Piemonte and Gruppo Torinese Trasporti, GTT with an underground railway running through the city, serviced by most lines. *Line 2 (Naples), Naples Metro Line 2 is an underground corridor where commuter rail services operated by Trenitalia traverse and service the urban center. *Bari metropolitan railway service


New Zealand

The Public Transport in Auckland, Auckland Metro network will be converted from a commuter rail system to a S-train system with metro-like frequencies with the completion of the City Rail Link in late 2024. The project will double frequencies to every five minutes at peak and add two underground stations within the Auckland City Centre.


Japan


Tokyo

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. behave more like S-Train lines with numerous mid-distance services from the outer suburban lines through operating into these lines to form a high frequency corridor though central Tokyo; Only to branch off and interoperate with other JR East suburban lines on the other side of central Tokyo. In addition, it is common for the numerous private railway companies to funnel train traffic into Through train#Japan, through operations with Tokyo subway lines; all but three of Tokyo subway, Tokyo's 13 subway lines serve as underground trunk lines for suburban rail operators to access Tokyo city center. This is a product of laws preventing private operators from constructing railways within the Yamanote Line, Yamanote Loop Line.


Kyoto - Osaka - Kobe (Keihanshin)

Unlike Tokyo a number of underground cross city corridors were constructed by suburban operators to allow suburban trains to access the city center. * 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. * Naniwasuji Line a proposed north south underground corridor allowing Nankai Electric Railway and JR West trains to run through Osaka and service Namba and Umeda.


Nagoya

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.


Malaysia

KTM Komuter, operated by Keretapi Tanah Melayu, mainly service in Klang Valley and Greater Penang.


Netherlands

"Randstadspoor" is a network of Nederlandse Spoorwegen#Types of train service, Sprinter train services in and around the city of Utrecht, similar to S-trains. For the realisation of this network, five new stations were opened: Utrecht Zuilen railway station, Utrecht Zuilen, Utrecht Terwijde railway station, Utrecht Terwijde, Utrecht Leidsche Rijn railway station, Utrecht Leidsche Rijn, Utrecht Vaartsche Rijn railway station, Utrecht Vaartsche Rijn and Houten Castellum railway station, Houten Castellum. Extra tracks have been built to create dedicated routes for these Sprinters, so they can call frequently without disturbing high-frequent Intercity services parallel to these routes. Similar systems are planned for The Hague and Rotterdam, the latter of which already has the Rotterdam Metro network.


Norway

Oslo Commuter Rail lines converge on a primary main line between Asker station, Asker and Lillestrøm Station, Lillestrøm.


Poland

In Poland, three comparable systems exist, but 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 (eng. Warsaw Fast Urban Rail) in the Warsaw urban area, with 4 lines and 46 stations. * Łódzka Kolej Aglomeracyjna (eng. Łódź Agglomeration Rail) is located in the center of Poland connecting satellite towns in and around Łódź. It is the largest commuter rail system in Poland, with 65 stations.:pl:Łódzka Kolej Aglomeracyjna It also operates some trains between Łódź and Warsaw. *Szybka Kolej Miejska (Tricity), Szybka Kolej Miejska w Trójmieście (eng. Tricity Fast Urban Rail), located in the Tricity, Poland, Tricity/Trójmiasto urban area, the three cities of Gdańsk, Gdynia and Sopot.


Russia

In Russian Federation, the systems with frequent electric trains, closest to S-Bahn are in Moscow: Moscow Central Circle and Moscow Central Diameters (term "S-Bahn" isn't used in Russia, but "ground metro" or "urban electric train" naming can be found). * MCC connects northern and eastern residential districts with downtown of Moscow, and actually counts as a line of Moscow Metro with the same tickets used. * MCD forms a S-Bahn-like suburban-urban-suburban railway set (with point A -- point B tickets necessary both to enter and to leave railroad network). The first S-bahn-like project (implemented before the 1917 revolution) was the railroad Moscow Central Circle, MCC uses now: ''Moskovskaya Okruzhnaya Zheleznaya Doroga'', literally Moscow-Around Rail Road, was a railway which used to go around the outskirts of Moscow back then. In a sense, Line 14 of Moscow Metro is the oldest Metro line since modern MCC uses M.O.Zh.D's unbroken, unoccipied circle of railways. There also was the Oranienbaum Electric Line in Saint Petersburg, St. Petersburg. Also, an approximate analogue was Beskudnikovskaya railway branch, which existed in Moscow between the 1940s and 1980s. The trains that shuttled along it did not go to the main lines, so it was a city transport.


Serbia

* BG Voz is an urban rail system that serves Serbian capital. It is fairly similar to German S-Bahn, but currently has only two lines, with plans for further expansion. Between 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 lines 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.


South Africa

S-Bahn-like train services in the country are called Metrorail (South_Africa), Metrorail, with much of the tracks exclusive to them and their lines converging on major trunk lines in their city centres.


South Korea

Seoul Subway Line 1 is a collection of frequent surface-running Korail urban railway services from the Gyeongin Line, Gyeongin, Gyeongbu Line, Gyeongbu and Gyeongwon Line, Gyeongwon Lines that feed into a core 7.8-km-long underground section run by Seoul Metro.


Spain

Madrid’s Cercanías Madrid, Cercanías commuter rail network runs mostly independently of other rail traffic and features several underground sections. Rodalies de Catalunya operates Barcelona's suburban rail services which traverse the city centre in two underground trunk routes, the Meridiana Tunnel and Aragó Tunnel. In Bilbao, two comparable systems operate; Cercanías Bilbao (of which lines C-1 and C-2 are mostly separate from the national rail network) and Euskotren Trena, which both feature underground sections in the city centre. Cercanías Málaga's C-1 line from Málaga Centro-Alameda railway station, Málaga Centro-Alameda to Fuengirola features several underground sections and uses a route mostly separate from the national rail network of Spain, aside from a small section between Málaga María Zambrano railway station, Málaga-María Zambrano and Victoria Kent.


Sweden

SL operates the Stockholm commuter rail, Pendeltåg network in the Stockholm metro area and it is integrated into the rest of the SL network. Although most stations are at-grade or overground, Stockholm City, Stockholm Odenplan, and Stockholm South are among the stations that are underground. Travelling on most destinations reachable from Stockholm's city centre costs the same as a subway (T-bana) or local bus ride and transfer windows between a Pendeltåg and subway/local bus are free within the validity of the fare purchased. A supplement is charged for journeys involving Arlanda airport and/or Uppsala. In addition to the Pendeltåg, SL operates the Roslagsbanan commuter rail network (also denoted by a J), which runs from Stockholm East station to the eastern and northeastern portions of Stockholm County and fares cost the same as a subway or local bus ride.


Switzerland

''S-Bahn'' is also used in German-speaking Switzerland. While French publications of those networks translate it as ''RER'', the line numbers are still prefixed with an S (e. g. S2). The oldest network in Switzerland is the Bern S-Bahn, established in stages from 1974 and has adopted the term S-Bahn since 1995. It is also the only one in Switzerland to use a coloured "S" logo. In 1990, the Zürich S-Bahn, which covers the largest area, went into service. S-Bahn services were set up in the course of the ''Rail 2000, Bahn 2000'' initiative in Central Switzerland (a collaborative network of ''Lucerne S-Bahn, S-Bahn Luzern'' and ''Zug Stadtbahn, Stadtbahn Zug''), St. Gallen (''St. Gallen S-Bahn, S-Bahn St. Gallen'') and Ticino (''Rete celere del Canton Ticino''). The ''Basel trinational S-Bahn'' services the Basel metropolitan area, thus providing cross-border transportation into both France and Germany. A tunnel connecting Basel's two large intercity stations (Basel Badischer Bahnhof and Basel SBB railway station, Basel SBB) is planned as ''Herzstück Basel, Herzstück Regio-S-Bahn Basel'' (lit. heart-piece Regio-S-Bahn Basel). The ''RER Vaud'' of Lausanne and the ''Léman Express'' of Geneva serve the area around Lake Geneva (''fr. Lac Léman''). Transborder networks for the Lake Constance-adjacent States of Germany, German states Baden-Württemberg and Bavaria, the States of Austria, Austrian state Vorarlberg and the Cantons of Switzerland, Swiss cantons Canton of St. Gallen, St. Gallen and Thurgau are under discussion. Possible names are ''Bodensee-S-Bahn'' and ''Rhine#Switzerland, Alpenrhein-Bahn''.

* ** Birmingham's four suburban lines are colour-coded. The green line is diesel while the others are powered by overhead wires. * Bristol ** MetroWest (Bristol), MetroWest is a proposed 5-line 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. * Glasgow ** Many of the rail lines around Glasgow are branded as Strathclyde Partnership for Transport. The trains used for these used to carry a different livery from the standard livery used by Scottish trains. The network includes most electrified Scottish rail routes. *Leeds ** The West Yorkshire Passenger Transport Executive, Metro run eleven lines which feed into Leeds, connecting the city with commuter areas and neighbouring urban centres in the West Yorkshire Urban Area, West Yorkshire Connurbation. * Liverpool ** Merseyrail consists of two lines 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. * ** Crossrail is similar to S-trains with a central core section which will be using a new, 22-kilometre(14 mi)-long, east–west twin tunnel under central London, splitting into two branches at either end. ** 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. This arrangement is similar to that found in Berlin. The system's 10 lines are not numbered and do not have distinct colours, but are divided into 6 regions. * Newcastle upon Tyne, Newcastle ** The Tyneside Electrics system 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.
