S-Bahn Germany

S-Bahn Germany

The S-Bahn is a hybrid urban-suburban rail system serving a metropolitan region predominantly in German-speaking countries. Some of the larger S-Bahn systems provide service similar to rapid transit systems, while smaller ones often resemble commuter or even regional rail systems. The name S-Bahn derives from Schnellbahn (lit. rapid train), Stadtbahn (lit. city train) or Stadtschnellbahn (lit. rapid city train).

Similar systems in Austria and German-speaking Switzerland are known as S-Bahn as well. In Belgium, it is known as S-Trein (Flemish) or Train S (French). In Denmark, they are known as S-tog, and in the Czech Republic as Esko or S-lines. In Milan, they are known as Linee S.

S-Bahn Characteristics

There is no complete definition of an S-Bahn system. S-Bahn are, where they exist, the most local type of passenger train service that stops at all existing stations on mainline networks inside and around a city (while other mainline trains only call at major stations).

They are slower than regional mainline trains, but usually serve as fast crosstown services within the city. The Copenhagen S-tog for example goes up to 120 kilometres per hour (75 mph), faster than most urban heavy rail and mass transit. S-Bahn trains generally serve the hinterland of a certain city, rather than connecting different cities, although in high population density areas a few exceptions to 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.

Most S-Bahn 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-Bahn lines. S-Bahn trains typically use overhead lines or a third rail for traction power. In Hamburg both methods are used, depending on which line is powered.

In smaller S-Bahn systems and suburban sections of larger ones, 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-Bahn corridors sometimes have sections of exclusive trackage of their own but parallel to mainline railways. Many of the larger S-Bahn 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 Berliner Stadtbahn in Berlin's S-Bahn, which is regarded as a tourist attraction. However, in more lightly used sections outside the city centre, S-Bahn services commonly share tracks with other trains.

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-Bahn 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 for S-Bahn systems reflects 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 systems like metros is typical for the S-Bahn. Where both S-Bahn and metro exist, the number of interchange stations between the two systems is substantial, with metro tickets being valid on S-Bahn services and vice versa. The S-Bahn Mitteldeutschland constitutes the main local railway system for Leipzig but also connects to Halle, where a few stations are located. The Rostock S-Bahn is an example of a smaller S-Bahn system.

S-Bahn Etymology

S-Bahn Germany, S-Bahn Austria and S-Bahn Switzerland

The name S-Bahn is an abbreviation of the German Stadtschnellbahn "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–Stettin railway from Berlin Nordbahnhof to Bernau bei Berlin station in 1924, leading to the formation of the Berlin S-Bahn.

The main line Berliner Stadtbahn ("Berlin city railway") was electrified with a 750 volt third rail in 1928 (some steam trains ran until 1929) and the circle line Berliner Ringbahn was electrified in 1929. The electrification continued on the radial suburban railway tracks along with the timetable moving to a rapid transit model with no more than a 20-minute headway per line where a number of lines overlapped on the main line. The system peaked during the 1936 Summer Olympics in Berlin with trains scheduled at least every 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. In 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, in 1938 the Nazi government broke ground for an S-Bahn-like rapid transport system in Lindwurmstraße near what is now Goetheplatz station on line U6. The system was supposed to run through tunnels in the city centre. 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, only began to operate prior to the 1972 Summer Olympics.

The term S-Bahn was a registered wordmark of Deutsche Bahn until 14 March 2012, when, at the request of a transportation association, the Federal Patent Court of Germany ordered its removal from the records of the German Patent and Trade Mark Office. Prior to this Deutsche Bahn collected a royalty of 0.4 cents per train kilometer for the use of the term.

S-Bahn 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". 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 86 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 .
