 suggested the construction of elevated railways, while AEG proposed an underground system. Berlin city administrators feared an underground would damage the sewers, favouring an elevated railway following the path of the former city walls; however, the neighbouring city of Charlottenburg did not share Berlin's fears, and disliked the idea of an elevated railway running along Tauentzienstraße. Years of negotiations followed until, on 10 September 1896, work began on a mostly-elevated railway to run between Stralauer Tor

Before the year ended, the railway had been extended: by 17 August, east to Warschauer Brücke (Warschauer Straße); and, by 14 December, west to Knie (Ernst-Reuter-Platz

The line underneath Leipziger Straße to Spittelmarkt opened in 1908; it was extended to Alexanderplatz by July 1913, with the Wilhelmplatz–Alexanderplatz route swiftly become the most popular of the Berlin U-Bahn. Three-and-a-half weeks later, on 27 July 1913, the northern extension to the S-bahn station (Schönhauser Allee

) on Nordring was also opened.

In a bid to secure its own improvement, Schöneberg also wanted a connection to Berlin. The elevated railway company did not believe such a line would be profitable, so the city took it upon itself to build the first local underground in Germany. Running as a subsurface railway from Hauptstraße, the 2.9 km (1.8 mi) line needed a second, underground station at its Nollendorfplatz

—and the subsequent economic difficulties faced by Germany—that prevented any further additions to the Berlin U-Bahn for ten years.

Second construction phase: 1923–1930


The early network ran mostly east to west, connecting the richer areas in and around Berlin, as these routes had been deemed the most profitable. In order to open up the network to more of the workers of Berlin, the city wanted north-south lines to be established. Its wishes were strengthened when, in 1920, the surrounding areas were annexed in the formation of Groß-Berlin (Greater Berlin), removing the need for many negotiations, and giving the city much greater bargaining power over the private (elevated railway company). The city also mandated that new lines would use wider carriages—running on the same, standard-gauge track—to provide greater passenger capacity; these became known as the Großprofil (large profile) network.

In 1912, plans were approved for AEG to build its own north-south underground line. Named the after its termini, it would connect Gesundbrunnen and Neukölln, via Alexanderplatz. Financial difficulties stopped the construction in 1919; the liquidation of AEG-Schnellbahn-AG, and Berlin's commitment to the Nord-Süd-Bahn, prevented any further development until 1926.

West Berlin paid an annual fee of DM20 million to permit trains on the C and D lines to run through eastern territory, although the trains were not allowed to stop on their way: the former stops became (ghost stations), patrolled by armed East-German border guards.

1961–1976 18


The pre-war U-Bahn line designations consisted of letters, with added Roman numerals in case of line branchings. This system continued to be used into the 1960s on both sides.

After the erection of the wall, East Berlin was left with line E and the eastern half of line A. This oddity and the fact that the two line network was simple to navigate anyway, caused line designations to be gradually abandoned there over the years.

West Berlin abandoned the letter based system in 1966 and replaced it by line numbers 1 through 9, the system still in place today. The shortest line in this system was line 5 which consisted of two stops only (Deutsche Oper - Richard-Wagner-Platz). It was closed in 1970, to be replaced by an extension of line 7 which opened a few years later. This move freed line number 5. West Berlin BVG then decided to reserve this line number for East Berlin's line E in case of reunification - the only line that ran exclusively in East Berlin territory and was therefore not yet covered in the new West Berlin system.

In 1984, BVG became the operator of the West Berlin S-Bahn
Berlin S-Bahn

 which until then had been operated
by East Germany's Deutsche Reichsbahn

. It incorporated the S-Bahn into its line numbering system by using the method of West German transport systems of giving new line numbers prefixed by "S" to the S-Bahn, and adding the prefix "U" to the existing U-Bahn lines. So "line 1" became "U1" etc.

After Berlin's reunification in 1990, East Berlin's line E was renumbered U5, as had been planned. At the same time, the eastern half of line A became U2 like its western counterpart, even though at the time they were not yet connected. When U2 was actually rejoined in 1993, the western branches of U1 and U2 were swapped, and the U3 disappeared from the map. What had been U3—a short shuttle line between Uhlandstraße and Wittenbergplatz—became part of the new U15, a line that in theory continued past Wittenbergplatz in parallel with U1, to Schlesisches Tor (and, when it was reopened in 1995, Warschauer Straße); in practice, particularly in off-peak hours, U15 was often operated as a shuttle identical to the old U3. In 2004, the full length of U15 was redesignated U1, and a new U3 was created from what had been the U1 west of Nollendorfplatz to Krumme Lanke. (This was the same route as the U2 until 1993, extended one station further east to Nollendorfplatz to enable trains to be reversed and to allow one-stop transfer to the U4).

Stations


Among Berlin's 173 U-Bahn stations there are many with especially striking architecture or unusual design characteristics:


Hermannplatz
Hermannplatz (Berlin U-Bahn)
Hermannplatz is a station in the Neukölln district of Berlin which serves as an interchange between the lines and . Operated by the BVG, it is one of the busiest stations on the Berlin U-Bahn system....

 station resembles something of a U-Bahn cathedral. The platform area is 7 metres high, 132 metres long and 22 metres wide. It was built in connection with the construction of the first North-South Line (Nord-Süd-Bahn), now the U8. The architecturally important department store Karstadt

 adjacent to the station, was being constructed at the same time. Karstadt contributed a large sum of money towards the decoration of the station and was in return rewarded with direct access from the station to the store. Hermannplatz was also the first U-Bahn station in Berlin to be equipped with escalators. Today, Hermannplatz is a busy interchange between the U7 and U8.


Alexanderplatz station is another of the more notable U-Bahn stations in Berlin, as well as being an important interchange between three lines (U2, U5 and U8). The first part of the station was opened in 1913 along with an extension of today's U2 line. In the 1920s Alexanderplatz

 itself was completely redesigned, both above and below ground. The U-Bahn station was expanded to provide access to the new D (today's U8) and E (today's U5) lines, then under construction.

 on the (U1). A provision for a sixth platform was included but has never been completed. The redesign also featured a new entrance building, which blended into the grand architectural styles of Wittenbergplatz and the nearby KaDeWe department store. The interior of the entrance building was again rebuilt after considerable war damage during World War II, this time in a contemporary 1950s' style. This lasted until the early 1980s when the interior was retro-renovated back into its original style. Wittenbergplatz station was presented with a London style "Roundel type" station sign in 1952, the 50th Anniversary of the Berlin U-Bahn. Today's station is an interchange station between the U1, U2 and U3 lines.

 (rail triangle) station is still reminiscent of a construction which can only be imagined today. The wye itself was built in the opening year 1902. Plans for a redesign were made soon after, because the wye was already obsolete. An accident on September 26, 1908 which claimed 18 to 21 lives was the final straw. The redesign and expansion of the Turmbahnhof, during which the station was still used, took until 1912. After World War II

 the station was put back into service on October 21 (lower platform), and November 18 (upper platform), 1945. However, service was interrupted again by the construction of the Berlin Wall. From 1972 onwards no trains were running on the lower platform, because servicing the U2 was no longer profitable due to the parallel traffic on the U1.

 lines are included, as are buses, Metro-Tram and Ferries: the single ride-pass is inclusive for all transportation considered part of the Berlin-Regional public transit system.

Ride-passes (tickets) are available in fare classes: Adult and Reduced. Children between the ages of six and 14, and large dogs, qualify for the reduced fare. Children below the age of six, and small dogs, travel free. There are no 'Senior Discounts'. Residents who have applied for and received a German Disability Identification card, showing 80% or more disability (ID's available from the Versorgungsamt, German Disability Office http://www.google.com/search?q=versorgungsamt), can ride without a pass, including an additional person (as a helper). The disability identification card must be in the owner's possession.

Residents: With unemployment in the east averaging 15%, another common fare class in Berlin is the S(ozial)-Class. These identification cards are cleared through the normal government offices, then fulfilled at a BVG ride-pass non-automated location. Provided either the Job Center (Arbeitsamt) for the resident who is out-of-work, or for people who cannot work/partially disabled, by the Sozialamt, the S-Class ride-passes normally restrict travel to the AB zones, and must be renewed (a new pass purchased at a non-automated location) on the 1st of the month.

Additional passes are available for those which want to bring their bicycle on the public transit. As of this writing, 4.70€ is the price of a bicycle day-pass, this is additional to the normal ride-pass. A bicycle-pass is included in the Student-class ride-pass, which is provided through the Universities.

For small dogs, ones which can be carried in hand, there is no additional fare requirement. For each large dog, a Reduced fare ride-pass must be purchased. Tourist Ride-passes, All-day, group passes, and season passes include a dog-fare.

BVG ride-passes are issued for specific periods of time, and most require validation with a stamping machine before they are valid for use. The validation shows the date and time of the first use, and from where the ticket was validated (in code), and therefore when the ticket expires. For example, once validated, an All-Day Pass allows unlimited use, but then expires at 3AM the following day. Unlike most other metro systems, tickets in Berlin are not checked before entering Tram-Metros, U-Bahn or S-Bahn stations. They are checked by the bus drivers upon entering. On the Metro, S-Bahn and U-Bahn, there are random spot checks inside by plainclothes traffic officers who have the right to demand to see each passengers ticket. Passengers found without a ticket or an expired/invalid ticket are fined: 40 euro per incident. The passenger may be required to pay on the spot, and is required on the spot to give a valid address to mail the relevant fine notice to (it does not have to be in Germany). On the third incident, the BVG calls the offender to Court, as there is now a history of 'riding without paying'.

.

Tickets can be bought for specific fare zones, or multiple zones. Most passengers who live in Berlin buy AB farezone tickets, while commuters coming in from the suburbs need ABC farezone tickets. If a ticket not valid for travel in a tariff zone is checked by a ticket inspector, the passenger is subject to a fine.


Short-term tickets
Single-journey tickets (Einzeltickets) are issued for use within specific fare zones, namely AB, BC, and ABC. They are only valid for two hours after validation, and cannot be extended. The BVG also offers single-day tickets (Tageskarte), which are valid for the entire day when first validated until 3 a.m. the next morning.


Long-term tickets
Long-term paper tickets are issued with validity periods of seven days (7-Tage-Karte) or one month (Monatskarten). The BVG is in the process of introducing the plastic

 MetroCard as a yearly ticket that also has additional features. The Metrocard also permits passengers to make reservations for hire cars at specific times, for example on weekends. It is expected that plastic Metrocards without such features will be made available they are more durable and ecofriendly than the paper tickets.


Tourist passes
The BVG offers tickets directed specifically for non-resident tourists of Berlin called the WelcomeCard and CityTourCard http://www.bvg.de/index.php/en/Bvg/Index/folder/710/name/For+Visitors. WelcomeCards are valid for either 48 or 72 hours, and can be used by one adult and up to three children between the ages of six and 14. WelcomeCards are valid in farezones ABC, and have the additional benefit of a reduction on entry fees to many museums and tourist attractions.

Unused stations and tunnels


There are several stations, platforms and tunnels that were built in preparation for future U-Bahn extensions, as well as those that have been abandoned following planning changes. For example, platforms have already been provided for the planned "U3" at Potsdamer Platz on the planned line to Weißensee. It is unlikely that this line, which had the working title "U3" will ever be built, so the platforms have been partially converted into a location for events and exhibitions. The Line number "U3" has been subsequently used to re-number the branch to Krumme Lanke

. It had been opened in 1902 and was renamed Osthafen in 1924. Today, only struts on the viaduct remain to indicate its location. In the post second World War period it was not thought necessary to rebuild the station, due its close proximity to Warschauer Straße station. Also its location was directly on the border between the Soviet and American sectors. Although a Berlin map dated 1946 does show the station renamed as Bersarinstraße after the Soviet General responsible for restoring civil administration of the city, this name was used later at another location.

Nürnberger Platz station was closed on July 1, 1959. It was replaced by two new stations on either side, Augsburger Straße and an interchange station to the U9 at Spichernstraße. Today, nothing remains of the station as a third track siding was constructed in its place.

Another tunnel, which once connected the U4 to its original depot and workshop at Otzenstraße (Schöneberg

), is still in existence. The connection from Innsbrucker Platz station to the depot was severed when a deep level motorway underpass was constructed in the early 1970s; however, the continuation of the tunnel at Eisackstraße is still in existence for a distance of 270 metres and now ends at the former junction to the workshop of the Schöneberg line.

The other U10 platforms remain unused and are not generally open to the public.

Currently, the tunnel is used as a storage area for theater props.

Future development


Berlin's chronic financial problems make any expansion not mandated by the Hauptstadtvertrag—the document that regulates the necessary changes to the city as the capital of Germany—unlikely. Furthermore, there is still great rivalry for construction money between the U-Bahn and the S-Bahn. After the construction boom that followed the reunification of the city, enthusiasm for further growth has cooled off; many people feel that Berlin's needs are adequately met by the present U- and S-Bahn. As of 2007, the only proposals receiving serious consideration aim to facilitate travel around the existing system, such as moving Warschauer Straße's U-Bahn station closer to its S-Bahn station.

There are several long-term plans for the U-Bahn that have no estimated time of completion, most of which involve closing short gaps between stations, enabling them to connect to other lines. The segment between Uhlandstraße

Although the two profiles are generally incompatible, Kleinprofil trains have been modified to run on Großprofil lines during two periods of economic difficulty. Between 1923 and 1927 on the Nord-Süd-Bahn, and between 1961 and 1978 on the E line, adapted Kleinprofil trains were used to compensate for the lack of new Großprofil trains: they were widened with wooden boards to reach the platforms; and had their power pickups adapted to accept power from the negatively-charged downward-facing third rail, instead of positively-charged upward-facing third rail.

As of 2007, Kleinprofil trains run on the U1, U2, U3, and U4 lines; and Großprofil trains operate on the U5, U55, U6, U7, U8, and U9 routes.

s, with a top speed of , had been built at the Warschauer Brücke workshop. In contrast to the earlier test vehicles, seating was placed along the walls, facing inward, which was considered more comfortable. Until 1927, U-Bahn trains had smoking compartments and third-class carriages. The trains were first updated in 1928; A-II carriages were distinguished by only having three windows, and two sliding doors.

After the division of the city, West Berlin upgraded its U-Bahn trains more rapidly than did East Berlin. The A3 type, introduced in 1960, was modelled on the Großprofil D type, and received regular modifications every few years. Meanwhile, A-I and A-II trains operated exclusively in East Berlin until 1975, when G-I trains, which had a top speed of , started to travel the Thälmannplatz–Pankow route. These were superseded in 1988 by the G-I/1 type, which used couplings that were incompatible with the older G-I carriages.

Following reunification, the A3 type was again upgraded as the A3L92, the first Kleinprofil type to use three-phase electric power

. In 2000, prototypes for a Kleinprofil variant of the H series were built; the HK differs from its Großprofil counterpart by not being fully interconnected—carriages are only interconnected within each of the two half-trains.

As of 2005, only trains of the HK, G-I/1 and A3(U/L) types are in active service.

Großprofil (large profile)


Großprofil trains are wide, and high. The first sixteen multiple units and eight ordinary carriages entered active service on the Nord-Süd-Bahn in 1924, after a year of using modified Kleinprofil trains. Designated B-I, the cars were long and each had three sliding doors; the large elliptical windows at the front of the train earned them the nickname, Tunneleulen (tunnel owls). Upgraded B-II trains were introduced in 1927, and continued to be used until 1969. The first 18-metre-long (59 ft) C-I trains were trialled in 1926, and two upgrades were produced before the end of the decade. The first U-Bahn trains to use aluminium in their construction, the C-IV types, were introduced in 1930. Many C-type trains were seized by Soviet forces in 1945, to be used in the Moscow Metro

The first D-type trains, manufactured in 1957, were built from steel, making them very heavy and less efficient; however, the DL type that followed from 1965 used metals that were less dense, allowing a 26% reduction in weight. In East Berlin, D-type trains bought from the BVG were designated D-I. Difficulties there in trying to develop an E series of trains led, in 1962, to the conversion of S-Bahn type 168 trains for use on the E line. These E-III trains were desperately needed at the time to allow modified Kleinprofil trains to return to the increasingly-busy A line but, following reunification, high running costs led to their retirement in 1994.

In West Berlin, the successor to the D-type was the F-type, which debuted in 1973. They varied from other models in having seats that were perpendicular to the sides of the train; from 1980, they also became the first U-Bahn trains to use three-phase electricity. In 1995, the original seating arrangement returned as the H series took up service. H-type trains are characterised by the interconnection of carriages throughout the length of the train; and they can only be removed from the tracks at main service depots.

As of 2005, only F and H-type trains are in active service.

Depots


Depots of the Berlin U-Bahn fall into one of two classes: main workshops ; and service workshops . The main workshops are the only places where trains can be lifted from the tracks; they are used for the full inspections required every few years, and for any major work on trains. The service workshops only handle minor repairs and maintenance, such as replacing windows, or removing graffiti

.

As of 2005, the only dedicated Kleinprofil depot is at Grunewald (Hw Gru/Bw Gru), which opened on 21 January 1913. The first Großprofil depot opened at Seestraße (Hw See/Bw See) in 1923, to service the Nord-Süd-Bahn. It has 17 tracks—2 for the main workshop, and 15 for the service workshop—but its inner-city location prevents any further expansion. Due to BVG budget cuts, the Seestraße depot also services Kleinprofil trains. Two further Großprofil service workshops are located at Friedrichsfelde (Bw Fri), and Britz-Süd (Bw Britz).

In the past, there were other workshops. The first opened in 1901 at Warschauer Brücke, and was the construction site for most of the early U-Bahn trains. The division of the U-Bahn network on 13 August 1961 forced its closure, although it was reopened in 1995 as a storage depot. A small depot operated at Krumme Lanke between 22 December 1929 and 1 May 1968; and, while the network was split, East Berlin's U-Bahn used the S-Bahn depot at Schöneweide, along with a small service workshop at Rosa-Luxemburg-Platz, which was closed following reunification.

Accidents


The Berlin ranks among the safest modes of transportation: its history features few accidents.

The most severe accident occurred at the original (rail triangle), where the main and branch lines were connected by switches that allowed the tracks to cross. On 26 September, 1908, a train driver missed a stop signal. As a result, two trains collided at the junction, and one fell off the viaduct. The accident killed eighteen people, and severely injured another twenty-one. 's triangular layout had already been deemed unsuitable for future developments; this incident—and a later, less-serious one—triggered its reconstruction as a multi-level station, starting in 1912.

On 30 June 1965, a train with brake failure stopped on the G line—today's U9—between and . Unaware of the faulty train, a mechanic working at the signal tower noticed that the leaving signal had been set to 'Stop' for a long time. Thinking it should be set to 'Go', after several attempts, he manually changed the signal, in defiance of regulations that strictly prohibited such actions. The following train, which had been waiting at , then left the station on the same track. With emergency brakes unable to prevent the accident, the two trains collided. One passenger was killed in the crash, and 97 were injured. The mechanic was fined 600,000 DM.

Fires can be particularly dangerous and damaging within an underground system. In October 1972, two trains and a 200 m length of tunnel were completely destroyed when the trains caught fire; the reconstructed tunnel is clearly differentiated from the old one. Another train burned out in the connecting tunnel between Klosterstraße and Alexanderplatz in 1987. On 8 July 2000, the last car of a GI/I train suffered a short circuit, burning out at the rear of the Deutsche Oper station

. Installation of Portugal's gift to the city was completed on 30 October 2002.

As a consequence of the Deutsche Oper incident, BVG decided to post an employee at every station with only one exit until a second exit could be built. Over the following few years, many of those stations—including Britz-Süd, Schillingstraße, Viktoria-Luise-Platz, Uhlandstraße, and Theo. Heuss Platz—were refitted with additional exits. By June 2008, the only remaining stations with no second exit, Konstanzer Straße and Rudow, had been fitted with second exits. Despite these changes, several passenger organisations—such as Pro Bahn, and IGEB—demand that stations with exits in the middle of the platform are also fitted with additional emergency exits. Many stations are built this way; meeting those demands would place a heavy financial burden on both the BVG and the city.

The U6 saw a particularly costly, though casualty-free, incident on 25 March 2003. Scheduled repair work on the line limited the normal service to between Alt-Mariendorf and Kurt-Schumacher-Platz
Kurt-Schumacher-Platz (Berlin U-Bahn)

; one train then shuttled back and forth between Kurt-Schumacher-Platz and Holzhauser Straße, sharing a platform at Kurt-Schumacher-Platz with the normal-service trains departing for their return journey to Alt-Mariendorf. Needing to pass several stop signals on the shuttle service, the driver had been given special instructions how to proceed. Unfortunately, he ignored the signal at the entry to Kurt-Schumacher-Platz, and ploughed into the side of a train heading back to Alt-Mariendorf. The impact wrecked both trains, and caused considerable damage to the tracks. Normal service did not resume for two days, and the removal of the two wrecked trains—which, surprisingly, could still roll along the tracks—also took nearly 48 hours.
