The Munich S-Bahn (German: S-Bahn München) is an electric rail transit system in Munich, Germany. "S-Bahn" is the German abbreviation for Stadtschnellbahn (literally, "urban rapid rail"), and the Munich S-Bahn exhibits characteristics of both rapid transit and commuter rail systems.
The Munich S-Bahn network is operated by S-Bahn München, a subsidiary of DB Regio Bayern that is itself a subsidiary of the German national railway. It is now integrated into the Munich Transport and Tariff Association (Münchner Verkehrs- und Tarifverbund, MVV) and interconnected throughout the city with the locally-owned Munich U-Bahn. Today, the S-Bahn covers most of the populated area of the Munich Metropolitan area of about 2.7 million inhabitants.
The Munich S-Bahn was established on 28 May 1972. It was intended as part of the scheme to provide an adequate transport system during the 1972 Summer Olympics held in Munich by connecting the pre-existing suburban rail services in the west and east of the city via a new tunnel section from Hauptbahnhof to München Ost station (Ostbahnhof).
The system has seven branches in the west, which were originally numbered from north to south from the S 1 (to Freising) to the S 7 (Wolfratshausen). As a result of operational requirements, which have since changed several times, particularly as a result of line extensions, these are coupled with the five eastern branches. This results in random numbering in the east. Two lines end at Munich East station (Ostbahnhof), these are currently S 1 and S 6. The first change was made in June 1991 when the branch to Ebersberg changed from S 5 to S 4. The line to Wolfratshausen was first called the S 10, but when it was connected to run over the trunk line it was changed to the S 7.
The S-Bahn branch in the east via Ismaning to the airport was designated as the S 8. Later this was combined with the original line S 3, which shared part the route of the S 8, and the new route is called the S 8. This eliminated route S 3. The old route S 5 was later largely replaced by the current S 3, so there is currently no line S 5.
In addition there are lines S 20 and S 27, which run from Munich Central Station (Hauptbahnhof) and Pasing to Deisenhofen. These two lines do not run through the trunk line tunnel. The numbers beginning with 2 comes from the time of the introduction of these lines, as the line to Holzkirchen via Deisenhofen still had the number S 2 (instead of the current S 3). These lines cross the Isar via Großhesselohe Bridge.
The diesel-powered line running over the Dachau–Altomünster railway is also part of S-Bahn network and is designated as S-Bahn line A. It starts from the S 2 in Dachau and runs to Altomünster. It is proposed that it be electrified and integrated as a branch of the S 2 as part of a € 520 million development program.
In the Deutsche Bahn time table, the S-Bahn lines are numbered from 999.1 to 999.8 and 999.20; line A is numbered as 999.30.
The basic interval of the Munich S-Bahn is one train every 20 minutes. On parts of some branches during peak hours there is a 10 minute frequency produced by added trains. A special case is the line to Erding, where on weekdays a mix of express trains from Erding and normal S-Bahn trains from Markt Schwaben runs in the morning peaks, producing a 10 minute frequency west of Munich East station. There are also occasional additional trains on the western section of the S4 and on the S1 between Freising and Munich during the peak hour, which do not continue past the Hauptbahnhof (not run through the trunk line tunnel). One of three trains do not run to the end some branches at off-peak times, so that on these outer sections trains run at 20 or 40 minutes alternatively.

The S-Bahn partly operates on its own routes (one or two tracks), parts of it are double-track lines where S-Bahn operations are mixed with other traffic (passengers and freight), and in some cases more than two tracks are available. In the latter case one-or two tracks are set aside for the S-Bahn operations only and the two other tracks are used for the remaining traffic.
In the following table, the route length is shown from Munich Hauptbahnhof or from Ostbahnhof (Munich East station) because it reflects the chainage officially applied to the lines. An exception is S27 where the chainage starts at Pasing.

Intra-Urban Long-Distance Lines
The little known connection between the Ostbahnhof and the Hauptbahnhof, called the "Suedring" runs south from Ostbahnhof, bends westward, passing over Kolumbusplatz, the Isar river, Poccistraße and Heimeranplatz to arrive at the Hauptbahnhof without any stops in between. Trains travelling on this route (DB50) are included in the MVV tariff scheme and offer a view of the city in only slightly more time than in the Stammstrecke tunnel.
Additional regional lines make calls at stations also served by the S-Bahn, but provide an effective skip-stop/express functionality for MVV patrons. Examples include:
- Garmisch-Partenkirchen to Munich, calling at Tutzing (S6) and Pasing (Stammstrecke)
- Augsburg to Munich, calling at Mammendorf (irregularly) and Pasing (Stammstrecke)
- Regensburg to Munich, calling at Moosburg, and Freising (S1)
- Rosenheim to Munich, calling at Grafing Bf (S4) and Ostbahnhof (Stammstrecke)
- Various southern lines of the BOB, calling at Holzkirchen (S3), and regional variants from Rosenheim calling at Kreuzstraße (S6) and Holzkirchen (S5) through Großhesselohe
- Lindau to Munich, calling at Geltendorf (S4)
- Nürnberg to Munich, calling at Petershausen (S2) and Dachau Bf (S2)
Expansion plans announced by the MVV include a series of "Express S-Bahns" dedicated skip-stop lines that would operate through the second planned "Stammstrecke."

An underground railway line for Munich was first proposed in 1928 in a report on the "relocation of traffic centres". An underground route would allow "direct long distance traffic to and through the city centre".
On 22 May 1938, the first tunnel, which was part of the north-south route, was started in the Lindwurmstraße, between the present-day underground stations Sendlinger Tor and Goetheplatz. In the speech of Julius Dorpmüller, the general director of Deutsche Reichsbahn, the project was called "S-Bahn" for the first time. Due to World War II the construction and plans for the Munich S-Bahn were set aside.
In 1965, the Federal Republic of Germany, the Free State of Bavaria, the state capital of Munich and the Deutsche Bundesbahn signed a contract on the construction of the Munich S-Bahn. The further development was most influenced by a decision made in Rome on 26 April 1966: The International Olympic Committee chose Munich over Detroit, Madrid and Montreal as the scene for the 1972 Summer Olympics. This resulted in a tight schedule: There were only six years to complete the Munich S-Bahn network.
Not only did the tunnel through the city centre have to be built, the full railway infrastructure had to be expanded. The network of suburban lines had to be changed over and modernized. A large number of stations had to be upgraded; the platforms were brought to a length of 210 m to allow for three-unit trains; the platform height was raised to 76 cm. However, the floor height of the trains used then and now is at ca. 1 m, which makes boarding difficult for people with wheelchairs or prams. Tunnel stations and platforms updated recently where no freight trains run feature a height of 96 cm, however.
On 25 February 1971 the topping-out ceremony could be celebrated in the core route tunnel. In May the first S-Bahn train of the ET 420 series was put into service on the route between Pasing and Gauting. On 1 September 1971 a regular advance service was started on that route.
On 28 May 1972, the Munich S-Bahn network was finally put into service with 360 km of tracks and 101 trains of the ET 420 series. It was the first time a S-Bahn network that size was put into service on a single date. The route S10 to Wolfratshausen (today S7) was operated with conventional push-pull trains from the southern wing of Munich Central Station. It was electrified later and connected to the core route after the construction of a 260 m tunnel crossing the large number of mainline rail tracks leading to Munich Central Station.
Three months later the German President Gustav Heinemann opened the 1972 Summer Olympics. During the Games there were two additional S-Bahn lines servicing the now-defunct station Olympiastadion (Olympic Stadium). The new S-Bahn system stood the test and transported 3.18 million passengers in 7,138 runs to and from the sports sites in only 17 days.
Since then the Munich S-Bahn network has been expanded multiple times. In 1992, the route between Ismaning and the newly opened Airport Munich II has been put into service. Until 2005, there was a 266 million euro programme to substantially extend the infrastructure. For example, the route Giesing-Deisenhofen has been upgraded with a second track. Since 2000, trains of the type series ET 420 have been gradually replaced by ET 423 trains.
- 15 June 1966 - Construction of the core route tunnel begins in Arnulfstraße.
- 28 April 1972 - first test runs on the tunnel route (Hauptbahnhof-Marienplatz-Ostbahnhof).
- 28 May 1972 - regular service with 360 route km begins.
- ET 420 ("Olympia train", 1972 to 2004. Currently withdrawn from service except ET420-001 which is used for special events)
- ET 423 (since 2000)
- VT 628 (on line A, which is not electrified)
- In 1989, the double decker trains used in the Netherlands were briefly used on the then S4 between Geltendorf and Ebersberg. Patrons were invited to fill out a questionnaire while onboard describing their experiences while boarding and riding the train. The concept was to increase passenger capacity at the same time as accommodating bicycles, prams, and wheelchairs with efficiency. The trains were pulled by a DB Class 120 locomotive at each end of the train.
Plans and further expansions
Current plans for further expansion include the following: 
- Second core route: Nearly all lines use the core route, creating a bottle-neck responsible for long delays from even the smallest disruptions. A second tunnel through the city centre is planned, which will be about 10 km (6 mi) in length and which is supposed to be finished in 2020. It will start between the stations Laim and Donnersbergerbrücke and lie north of the current tunnel. Just before Munich East it will fork, with one fork going to Munich East and the other to Leuchtenbergring. In between, only two stations, Central Station and Marienhof (slightly north of Marienplatz), are planned. The tunnel was chosen over another variant to build an S-Bahn along the railway "south ring". It is not known if this capacity expansion will also be used for intercity traffic travelling eastwards following the cancellation of the München 21 project.
- Extension of S7 to Geretsried (Geretsried Süd railway station) via Gelting and Geretsried Mitte. (Currently in Planning / On Hold)
- Erding Ring: connection of the ends of S1/S8 (airport) and S2 East (Erding) (Currently in Planning)
- Possible relocation of the S2 East to the Munich International Trade Fair site. (Currently on hold)
- Electrification of Dachau–Altomünster railway (Line A) between Dachau station and Altomünster (by 2014)[dated info]
