On 5 December 1906, under the description the Prussian (railway division) of Altona opened with steam trains between Blankenese, Altona (Elbe) and Hamburg.
The Stadt- und Vorortbahn (City and Suburban railway) included the Altona-Blankenese line (Altona-Blankeneser Bahn, opened in 1867), the local tracks of the Hamburg-Altona link line (Verbindungsbahn, opened in 1866) and a new section to Ohlsdorf.
The Verbindungsbahn had been extended from one track to four and level crossings) eliminated between 1893 and 1903. The new double-track line adjoining it was completed in the summer of 1906 after an eight-year construction period. It ran alongside the Lübeck–Hamburg line of the Lübeck-Büchen Railway Company as far as Hasselbrook and then on its own tracks as far as the new Ohlsdorf cemetery. A new main cemetery with good transit connections was necessary in part due to the extension of the central railway lines, which had reduced the area of the existing already strained cemeteries near the city's medieval fortifications.
1907/08: First electric operation

The line was electrified with overhead lines supplying alternating current at 6.6 kV, 25 Hz. The electricity came from a coal-fired power station in Leverkusenstraße in Bahrenfeld, which also provided power to the Altona harbour railway.
The first electric trains ran on 1 October 1907, and from 29 January 1908 the line from Blankenese to Ohlsdorf was served exclusively by electric trains. These dates are considered the birthdates of the S-Bahn.
1924: Network expansion along the Alster valley railway
A railway line constructed and operated by a local company in 1914 and taken over by the district of Stormarn after bankruptcy, led from Ohlsdorf to Poppenbüttel in Prussia, with the goal of connecting neighbouring settlements along the Alster river. It was known as the Alster Valley Railway. It opened in 1918 with petrol-powered trains. The district of Stormarn gave the line to the German Imperial railway company, which electrified it and provided the extension of the Hamburg-Altona City and Suburban railway to Poppenbüttel in 1924.
1934: Designation as an S-Bahn
The term S-Bahn was first coined and used in Berlin from 1930, where a similar system on the had been operated since 1924; it was first used by the German Imperial railway with reference to its Hamburg-Altona City and Suburban railway in 1934. The term was also used to describe non-electric services on lines within the local suburban tariff: the steam-powered lines from Blankenese to Wedel, from Altona to Elmshorn, from Hamburg to Friedrichsruh and to Harburg. Since 2002, lines not served by S-Bahn have been designated "Regional railway lines".
1939/40: Moving to the DC system

In the 1930s, after almost 30 years of service, the necessity to renew the trains and infrastructure had become apparent. Since the DC system had proved itself over more than a decade with the Berlin S-Bahn, where the 750 volt DC power was supplied by a third rail, the German Imperial Railway decided to adopt the same system for Hamburg in 1937 and to abandon overhead AC. In order to allow improved acceleration, the S-Bahn uses 1200 volts: as a consequence, Berlin and Hamburg rolling stock are not compatible with each other. The first DC trains, of the type ET 171, were delivered in 1939; daily service began in July 1940 alongside the AC trains. Due to the second world war and the post war years with their shortages, mixed usage lasted until 1955.
The basic DC train unit consisted of three four-axle carriages, each with four sliding double doors per side. The middle carriages had upholstered seats for second class, while the motorised end carriages had third-class wooden seats.
Network extensions from 1950 to 1965
The DC S-Bahn was extended along the single-track suburban line from Blankenese to Sülldorf in 1950 and to Wedel in 1954. A section of the mainline railway between Hamburg and Berlin, which, due to the division of Germany, had very little traffic, between Haupbahnhof and Bergedorf was added to the network in 1959 by the addition of the third rail. This was the first section where S-Bahn and mainline trains (the number of the latter remained small until 1990) shared tracks. It was the second S-Bahn line, from Bergedorf via Berliner Tor to Altona. In 1962 a connecting curve was constructed from the Verbindungsbahn at Holstenstraße to the Altona-Kaltenkirchen railway, whose terminus was relocated to Langenfelde. The S-Bahn was extended in 1965 along the AKN to Eidelstedt and from there along the mainline tracks towards Kiel as far as Elbgaustraße.
HVV and a line numbering system
In 1965, the German Railway, along with two local transport companies, founded the Hamburger Verkehrsverbund, a common tariff system for U-Bahn and bus lines. The S-Bahn joined in December 1966. From January 1967, the S-Bahn lines were designated S1−S6 (see ). Line designations with a leading letter "S" have since been adopted for other S-Bahn systems in the German-speaking world. Analogically, U-Bahn lines got the leading letter "U".
Network extension after 1967

To ease the strain on the central Verbindungsbahn ("connection railway"), a second main connection was constructed, the City S-Bahn, which traverses the city centre in a tunnel. The first section was opened in 1975 between Hauptbahnhof and Landungsbrücken, the extension to Altona in 1979 and was completed in 1981 with the connection above ground to Diebsteich. 1983 saw the opening of the line via Wilhelmsburg to Harburg Rathaus, a long stretch of which runs along the existing mainline. Through Hammerbrook the trains run on a concrete viaduct and in a tunnel under the centre of Harburg. The line was extended in 1984 along the Niederelbebahn to Neugraben.
The line to Bergedorf was placed on separate tracks due to increased traffic on the main line during the 1990s as a result of German reunification. For the same reason, S-Bahn service between Bergedorf and Aumühle was suspended in 1994. The section to Reinbek was reopened in 1997; completion to Aumühle was delayed until 2002 due to court challenges from local residents. In 1999, Allermöhe station (between Mittlerer Landweg and Nettelnburg) opened in the new housing development of Neu-Allermöhe West.
The ground breaking for a 3.3 km long line from Ohlsdorf to the airport took place in 1991, and again in 2001; the line was opened on 11 December 2008 and has been fully operational since 12 December 2008. Northbound S1 trains split at Ohlsdorf, the front section to the airport, the rear section continues to Poppenbüttel.
The S-Bahn is operated by S-Bahn Hamburg GmbH, a subsidiary of Deutsche Bahn AG. The company is answerable to DB Regio Nord and was formed in 1997.where startup windows 7 where to find solutions which system of equations is consistent and dependent how many business weeks in a year where london is located in world map where does energy come from science startup who ends up with dalmi how many technology companies in the world how many project management methodologies are there where is primitive technology from how manager treat their staff how many solutions calculator where to design stickers how project ipad to tv where to manage subscriptions on iphone what company makes plan b why solution is a homogeneous mixture how many startup fails where from samsung company where management skills who medical equipment list which product results from the breakdown of fibrin when solution of ni2 and nh3 in startup who ends up with who how much tech savvy are you why manufacturing business whose project is mrt 7 how project management improves an organization s success who science division where from the worker alienation according to marx where to print business cards when project tiger was launched how much project coordinators make why workers leave their jobs what solutions are hypertonic where to build science nexus where is product key for microsoft office where does technology come from how many engineering degrees are there which manager has won most ucl where did workers go how far london to paris where to use entrepreneur where to design shirts which product is made from a renewable resource why engineering is a good career why entrepreneurs fail why tech investment banking how much system boiler which manufacturer has the best warranty how development leads to democracy which management approach is the best what are modern technological devices how engineering students study why london is better than new york how far phone from bed when entrepreneurial activities slow down how often is continuously how product placement works whose immune system is stronger how design awards where's my device how start up a conversation which london airport is better how equipment jackson michigan where to manage kindle unlimited how many london airports are there how technology has changed our lives who roadmap snakebite how much management fee for property how long science museum london how often to service well what management is how many products are made from oil manager who lead who solution recipe for rehydration where is sandro from project runway now when startup season 4 why startup interview questions how much business permit in quezon city what technology can mennonites use how technological advancements affects humanity how much start up when london bridge is falling down where to find system ip address startup where is izzy's mom how tech decks are made how many tech companies are in the bay area how to start the startup what company is worth the most why equipment is important how much project coordinators make from where manager derive performance expectation how much engineering courses how much company car tax calculator how many manufacturing company in india where product key windows 10 where teachers get paid the most whom synonyms and antonyms where technology is headed how often should you use stim where to design shirts which system of equations is consistent and dependent when device a has a cable why workers compensation insurance why workers go on strike how many solutions does this have what solutions can be used in a nebulizer how many manager challenges in baseball how system call works in linux how products are tested on animals where is primitive technology from how many business does shaq own which solutions does iqbusiness offer how tech decks are made what product sells the most on amazon who developed the triarchic theory of intelligence which business is an example of a multinational corporation
