The majority of people in this region continued to be Roman Catholics, even after the Protestant Reformation influenced populations in northern Germany. In the late 18th and early 19th century, Künzelsau , the capital of the Hohenlohe district , became the centre of emigration to the UK of pork butchers and bacon factors. The pioneers noticed
378-481: A combination known as 'controlled passive tilt' (制御付き自然振子式), where tilt is initiated passively but controlled (and slowed) by computers through mechanical active suspension - culminated post-privatisation with the 2000 series DMU, built for JR Shikoku and introduced on the Shiokaze and Nanpū limited express services in 1990. With problems of ride nausea and track wear alleviated, the benefits of tilting trains on

Pforzheim University is one of the oldest Fachhochschulen in Germany which is renowned and highly ranked for its Engineering and MBA programs. The state has the highest density of universities of any state in Germany. Railways form
756-541: A growing desire in the 1960s and 1970s to build high-speed rail networks, a problem arose: the amount of tilt appropriate for high-speed trains would be over-tilted for lower-speed local passenger and freight trains sharing the lines. Japan's early bullet train efforts of the 1960s avoided this problem by laying all-new lines as part of a re-gauging effort, and France's TGV followed the same pattern. Other operators did not have this luxury and were generally limited to much lower speeds. Spain's national railway Renfe took

In Italy, the studies for a tilting train started in the mid 1960s and the concept was patented in 1967 by two engineers of Fiat railway materials, Franco di Maio and Luigi Santanera. A number of prototypes were built and tested, including an automotrice (self-propelled) derived from ALn 668 ,
1386-468: A routine check. The tilting mechanism has been switched off since 23 October 2008, and the maintenance intervals were drastically reduced which led to major service disruptions. Much of the technical layout is derived from the ICE 3 . Austria's ÖBB has purchased three units in 2007, operating them jointly with DB for services from Germany to Austria. Even though DB assigned the name ICE-T to class 411/415,

#17327870232541512-674: A similar effect by using on-board computers to limit tilt, initiated using inertia (as in traditional passive tilt). Automatic train stop beacons are used to inform computers of the precise location of these trains and limit natural tilt to angles specified by track data. A high-speed tilting train is a tilting train that operates at high speed, typically defined as by the European Union to include 200 km/h (124 mph) for upgraded track and 250 km/h (155 mph) or faster for new track. Tilting trains operating at 200 km/h (124 mph) or more on upgraded track include

Although poor in workable natural resources (formerly lead, zinc, iron, silver, copper, and salts) and still very rural in some areas, the region is heavily industrialised overall. In 2003, there were almost 8,800 manufacturing enterprises with more than 20 employees, but only 384 with more than 500. There are 3,779 companies in Baden-Württemberg corporate family which come to 1000–5000 employees in total. The latter category accounts for 43% of

The politics of Baden-Württemberg have traditionally been dominated by the conservative Christian Democratic Union of Germany (CDU), which had led all but one government since 1952 until 2011. In the Landtag elections held on 27 March 2011 , voters replaced
2520-835: The Acela in the US, the X 2000 in Sweden, the Pendolinos and Super Voyagers in the United Kingdom, and the ICE TD in Germany (the latter two being diesel powered). Some older high-speed lines were built for lower line speeds (≤ 230 km/h (143 mph)); newer tilting trainsets can maintain higher speeds on them. For example, the Japanese N700 Series Shinkansen may tilt up to one degree on

#17327870232542772-798: The Chesapeake & Ohio Railway , who began development of what would become the UAC TurboTrain using the same system. The TurboTrain entered service in the US and Canada in 1968. The first successful European tilting train design was the Talgo in Spain, developed in the 1970s as a lightweight, fast train using passive tilt. Renfe, adopted the system widely, but was restricted to the Iberian peninsula initially. The first full commercial application of passive tilting trains appeared in early 1980s with
2898-810: The DB Class 403 (1973) built decades earlier - created a generation of trains with more limited tilt (around 2°) but are more economical to build and easier to maintain. The experimental 300X built in 1995 developed into the N700 series , the first revenue-earning tilting Shinkansen unit in 2007. Applications to Shinkansen lines - which would not have benefitted greatly with mechanical tilting mechanisms due to their already shallow curves that allow high speeds - allowed for greater ride comfort, less track wear and slightly higher speeds leading to increased frequency. The simplicity of this technology made it possible for smaller private operators to introduce tilting trains, such as
3024-485: The Dresden – Munich line, but these class 605 (ICE-TD) units experienced trouble from the start. After breaking an axle in 2002, all remaining 19 units (one fell off a working platform) were taken out of service. Even though one year later the trains were admitted to service again, DB judged their operation to be overly expensive. In 2006, those trains were used for amplifier trains and from 2008 to 2017, they ran on

In 1989, the old technologies and concepts of some parts of the ETR 450, and the introduction of new technologies in traction, led to the development of the next generation. The result was the ETR 460 , styled by Giorgetto Giugiaro , a train that began service in 1996. Though plagued by technical problems,

The first test of a Talgo in the United States was the John Quincy Adams with Fairbanks-Morse P-12-42 tested by the New York, New Haven & Hartford Railroad in 1957–1958. Due to technical troubles and the precarious financial state of the New Haven railroad, the trainset was stored. The idea caught the interest of

Researchers have found that if the tilting motion is reduced to compensate for 80% or less of lateral apparent force, then passengers feel more secure. Also, motion sickness on tilting trains can be essentially eliminated by adjusting the timing of when the cars tilt as they enter and leave the curves. A similar technology widely adopted across Asia and Oceania, known as controlled passive tilt , achieves

This experiment demonstrated the need for an active suspension system to tilt the coach bodies. The Spanish Talgo company had introduced the first widely successful shared-bogie system, which allowed cars to be connected end-to-end using a single bogie instead of each car having its own bogies at either end. This design saves weight and can reduce rail wear. In

This system used a large A-frame connected to the centre of the bogie that was as high as the cars. At the top of the A was a bearing system that the cars attached to, and a spring and damping system to smooth its motion. Because the cars were connected at this high point, they could swing to either side around

The effect could be felt under maximum speed and tilt, when the combination of tilting outside view and lack of corresponding sideways force can be disconcerting to passengers, like that of a " thrill ride ". More limited and slower tilt could be achieved using active, or 'forced', tilting mechanisms. In trains adopting these mechanisms tilt
8694-518: The fact that many engineering structures had to be built and the line suffered from difficult ground conditions, requiring a total of 32 bridges. The steep section between Balingen and Ebingen was built largely on an embankment in order to avoid landslides as a result of poor soil conditions on the escarpment. The total length of the Tübingen–Sigmaringen line was 87.505 km, of which 40.409 km lay in Hohenzollern, then Prussian territory. The construction costs amounted to 23,316,753.12 marks . Under
8820-404: The fixed pantographs limited this to 2°. Shortly after the train had gone into service, the tilting technology was disabled as many passengers experienced motion sickness because the pivotal point was too low. The next attempt was made with DMUs and the proven Italian hydraulic active tilting system. Between 1988 and 1990, DB commissioned 20 Class 610 units for fast regional traffic. This time
8946-481: The flower island of Mainau , and the hometown of the Zeppelin , Friedrichshafen a.o., are especially popular for outdoor activities in the summer months. In spring and autumn (April/May and September/October), beer festivals (fun fairs) take place at the Cannstatter Wasen in Stuttgart. The Cannstatter Volksfest , in the autumn, is the second-largest such festival in the world after the Munich Oktoberfest . In late November and early December Christmas markets are
9072-493: The former pre-war states, the majority of voters overall (69%) voted in favor of a merger. Baden-Württemberg officially became a state on 25 April 1952. There were still opponents to the merger of Baden and Württemberg, however. In 1956 the Federal Constitutional Court decided that the population of Baden should have their say in a separate referendum. The second referendum was delayed, however, and
9198-507: The great adaptability of the region's economy has generally helped it through crises. Half of the employees in the manufacturing industry are in mechanical and electrical engineering and automobile construction. This is also where the largest enterprises are to be found. The importance of the precision mechanics industry also extends beyond the region's borders, as does that of the optical, clock making, toy, metallurgy and electronics industries. The textile industry, which formerly dominated much of
9324-670: The highest point of the line of about 730 metres before Albstadt-Ebingen. On the climb is the largest bridge on the line, the 77.35 metre-long viaduct in Albstadt-Lautlingen. The line continues down the Schmeie river, which it frequently crosses and, after passing through two tunnels, eventually reaches the valley of the Danube at Inzigkofen , where it joins the Tuttlingen–Inzigkofen railway . Immediately after crossing
9450-581: The historical territories of Baden , Prussian Hohenzollern , and Württemberg . Baden-Württemberg became a state of West Germany in April 1952 through the merger of South Baden , Württemberg-Baden , and Württemberg-Hohenzollern . These states had been created by the Allies as they separated traditional states into occupation zones after World War II Baden-Württemberg is especially known for its strong economy with various industries like car manufacturing , electrical engineering , mechanical engineering ,
9576-660: The international borders within its waters not being clearly defined. It shares the foothills of the Alps (known as the Allgäu ) with Bavaria and the Austrian Vorarlberg , but Baden-Württemberg itself has no mainland border with Austria. The Danube is conventionally taken to be formed by the confluence of the two streams Brigach and Breg just east of Donaueschingen . The source of the Donaubach , which flows into
9702-547: The issues between Württemberg and Prussia , because the line crossed Prussia's Hohenzollern Province ( Hohenzollernsche Lande ). The first section between Tübingen and Hechingen was opened to traffic on 29 June 1869. The inauguration of the line between Hechingen and Balingen was delayed to 1 August 1874 by the Franco-Prussian War . The remaining section to Sigmaringen was opened on 1 July 1878. The construction period of approximately nine years can be explained by
9828-476: The late 1960s, through the 591 Series that developed into the highly successful Hitachi 381 series , that has been in service since 1973. In parallel Fiat Ferroviaria produced the experimental Y 0160 in 1970, that would evolve into the Pendolino family, in 1976, and operated in 11 countries. All of these had problems with short curves like those in switchyards, where they tended to sway about. Also, because of
9954-506: The latter, even if below the normal 200 km/h (124 mph) threshold, whilst operating at 250 km/h (155 mph) or faster, usually with tilt disabled, on the high speed lines. The first experimental tilting train concept was the pendulum-suspension "chair" cars designed by the Pacific Railway Equipment Company. The first prototype, with an articulated bogie system, was built in 1937 and tested on
10080-426: The line and Engstlatt station was reopened and a new station called Albstadt-Ebingen West was opened. In the early 1980s, the old Albstadt-Laufen station, which was some distance from the town was replaced by a station in the town. The former station is now an operating station used as a crossing loop on the single track line; an additional crossing loop was built as part of Albstadt-Ebingen West station. The upgrading of
10206-512: The line between Tübingen and Sigmaringen operated on 31 May 1997. In subsequent years, however, locomotive-hauled trains were repeatedly used for extended periods as a replacement for tilting trains that could not be operated. In the summer of 1997, Hohenzollerischen Landesbahn (HzL) took over the operation of all Regionalbahn (RB) services on the Zollernalb Railway, using Regio Shuttle RS1 diesel railcars. Express services remain
10332-479: The line. In the early morning and late evening there are also deviations from the basic operating pattern. Freight traffic was operated up to 31 December 2001 by the former Deutsche Bahn subsidiary, DB Cargo , hauled by class 294 and 365 locomotives. Under the MORA C concept all freight operations on the line would have been abandoned in 2001, but this was averted as the result of an agreement between DB Cargo and
10458-453: The local Swabian , Alemannic and Franconian dialects, is sometimes used as a synonym for Baden-Württemberg. Baden-Württemberg is formed from the historical territories of Württemberg , Baden and Prussian Hohenzollern . Baden spans along the flat right bank of the river Rhine from north-west to the south ( Lake Constance ) of the present state, whereas Württemberg and Hohenzollern lay more inland and hillier, including areas such as
10584-413: The majority of passenger services were changed to operate with class 628.2 diesel multiple units, which were then new. Uerdingen railbus and class 627.0 diesel multiple units were used on individual scheduled services until 1997. Class 215 diesel locomotives were used only for a few passenger services and were becoming less and less used for freight transport. The last scheduled locomotive-hauled service on
10710-597: The market. Starting in the 1970s, regional rail around major cities has been transformed into high-frequent S-Bahn networks, currently the following systems exist (partly) in Baden-Württemberg: Stuttgart S-Bahn , Rhine-Neckar S-Bahn , Breisgau S-Bahn and Basel S-Bahn . In and around the cities of Karlsruhe and Heilbronn, the Karlsruhe Stadtbahn system combines elements of traditional S-Bahns with tram operations within
10836-699: The media describing the initial revenue run as both fifteen years late , and the queasy rider ; the sets only briefly entering full revenue operation in 1985, before being withdrawn and the associated technologies sold to Alstom / Fiat Ferroviaria . By this time, the Canadian LRC design had become the first active tilting train to enter full commercial service, starting with Via Rail in 1981. Aeroplanes and bicycles tilt inwards when cornering, but automobiles and trains cannot do this on their own. Vehicles with high centres of gravity rounding sharp curves at high speeds may topple over. To make their turns easier,
10962-740: The microclimates of Black Forest and Allgäu up to 13 °C (55 °F) in the Upper Rhine Valley. Baden-Württemberg is divided into thirty-five districts ( Landkreise ) and nine independent cities ( Stadtkreise ), both grouped into the four Administrative Districts ( Regierungsbezirke ) of Freiburg , Karlsruhe , Stuttgart , and Tübingen . [REDACTED] The 35 districts: Baden-Württemberg contains nine additional independent cities not belonging to any district: The Baden-Württemberg General Auditing Office acts as an independent body to monitor public offices' correct use of public funds. The state parliament of Baden-Württemberg
11088-460: The neo-liberal thinktank Initiative for New Social Market Economy and the trade newspaper Wirtschaftswoche awarded Baden-Württemberg for being the "economically most successful and most dynamic state" among the 16 states. The unemployment rate stood at 3% in October 2018 and was the second lowest in Germany behind only Bavaria and one of the lowest in the European Union . Baden-Württemberg
11214-490: The network. Engineers at the research division , opened in 1964, had done fundamental work on vehicle dynamics, with the APT to a degree an extension of this. The existing Chief Mechanical and Electrical Engineers department was overlooked by the new project, creating resentment with its engineers. The work included experimentation with aluminium bodies, turbines, suspension and bogies, in cab signalling, automatic train protection, and active tilt. The APT-E (E for experimental)
11340-456: The newly developed tilting system as well as chassis and axles, and was judged unsuccessful. The tilting system was out of service until 2006, when hardened axles and system updates solved the problems. In consideration of these problems DB ordered a full re-engineering, resulting in the development of Class 612 . Starting in 1998, a total of 192 units were commissioned by DB. The tilting system proved to be reliable. In 2004, cracks were detected in
11466-446: The outer edge of a roadway of a high-speed highway or outer rail of a railway may be canted (raised) upward around the curve. The combination of tilt and centrifugal force combines to produce an effective acceleration that is down through the floor, reducing or eliminating any sideways component. The particular angle of tilt ("superelevation") is determined by the intended vehicle speed — higher speeds require more banking. However, with
11592-571: The popular Kretschmann and his Greens were reelected and, with their nationwide best result, turned out first place for the first time in any election in German history. However, because of the Social Democrats' heavy losses, the Greens formed a coalition government with the Christian Democrats, the second Kretschmann cabinet . After the most recent election in 2021, the Greens-CDU coalition was upheld. Although Baden-Württemberg has relatively few natural resources compared to other regions of Germany,
11718-585: The pristine Danube valley Swabian Alb (with Hohenzollern Castle and Sigmaringen Castle ), as well as the largely pristine Swabian Forest , the Upper Rhine Valley , and Lake Constance , where all kinds of water sports are popular, with the former Imperial, today border town of Konstanz (where the Council of Constance took place), the Neolithic and Bronze Age village at Unteruhldingen ,
11844-473: The project because of financial problems, and the project was temporarily interrupted, as the service in 1983. The train was used in demonstration campaigns to foreign countries like Germany, Switzerland, Czechoslovakia and Yugoslavia. A second unit was built for service to the wide-gauge Renfe Spanish lines in 1977, under the nickname of Platanito. The service didn't last of long, because problems with Spanish tracks made Platanito of little use. New interest by
11970-615: The region of Grand Est ), and Switzerland (cantons of Basel-Landschaft , Basel-Stadt , Aargau , Zürich , Schaffhausen and Thurgau ). Most of the major cities of Baden-Württemberg straddle the banks of the Neckar River , which has its source in Villingen-Schwenningen and runs downstream (from southwest to the centre, then northwest) through the state past Tübingen , Stuttgart , Heilbronn , Heidelberg , and Mannheim . The Rhine (German: Rhein ) forms
12096-523: The region, has disappeared from Baden-Württemberg. Research and development (R&D) is funded jointly by the state and industry. In 2001, more than a fifth of the 100,000 or so persons working in R&;D in Germany were located in Baden-Württemberg, most of them in the Stuttgart area. Baden-Württemberg is also the region with the highest GDP of the Four Motors for Europe . A study performed in 2007 by
12222-582: The responsibility of Deutsche Bahn and its subsidiary DB ZugBus Regionalverkehr Alb-Bodensee , which uses class 611 tilting trains, operating as Interregio-Express (IRE) services. Currently three services operate on the Zollernalb Railway at two-hourly intervals during the daytime: The Interregio-Express trains between Tübingen and Albstadt-Ebingen stop only in Mössingen, Hechingen and Balingen. The Regionalbahn services stop at all stations, but some only if required. Between Tübingen and Albstadt-Ebingen
12348-594: The results were quite satisfying and allowed a significant reduction of running times. The Class 610 sets was followed by the Class 611 , which basically was built for the same purpose (fast regional traffic with up to 160 km/h (99 mph) on twisting non-electrified lines). The Class 611's tilting system was electric, with a maximum 8° tilt, based on military technology from the Leopard tank . After entering service in 1996, this 50-unit class experienced problems both with
12474-408: The river Neckar, are popular smaller towns. Sites of former monasteries such as the ones on Reichenau Island and at Maulbronn (both World Heritage Sites ) as well as Bebenhausen Abbey are to be found. Baden-Württemberg also boasts rich old Free Imperial Cities such as Biberach , Esslingen am Neckar , Heilbronn , Ravensburg , Reutlingen , Künzelsau , Schwäbisch Hall and Aalen as well as
12600-574: The river, the line reaches Sigmaringen station at 574 m above sea level. The Zollernalb line, running from Tübingen to Sigmaringen via Hechingen, also known as the Hohenzollern Railway ( Hohenzollernbahn ), was built during the fourth period of construction of the Royal Württemberg State Railways ( Königlich Württembergischen Staats-Eisenbahnen ) from 1867 to 1878. A treaty signed on 3 March 1865 dealt with
12726-661: The second most popular theme park in Europe, after Disneyland Paris . Baden-Württemberg is home to some of the oldest, most renowned, and prestigious universities in Germany, such as the universities of Heidelberg (founded in 1386, the oldest university within the territory of modern Germany), Freiburg (founded in 1457), and Tübingen (founded in 1477). It also contains three of the eleven German excellence universities (Heidelberg, Tübingen, Konstanz and Karlsruhe and formerly, Freiburg ). Other university towns are Mannheim and Ulm . Furthermore, two universities are located in

The residential (court) towns of Ludwigsburg and Karlsruhe , the spas and casino of luxurious Baden-Baden , the medieval architecture of Ulm ( Ulm Münster is the tallest church in the world), the vibrant, young, but traditional university towns of Heidelberg and Tübingen with their old castles looking out above
12978-611: The slow and twisty nature of its conventional-speed, narrow gauge network, tilting trains were introduced as a way to speed up services on its congested main lines. The interurban Odakyu Electric Railway began Japan's first experiments in tilting technology in the 1960s by fitting pneumatic bogies to their electric railcars, while the Japanese National Railways pioneered their form of passive-tilt technology on their experimental 591 series EMU with commercial express services on mountain lines in mind. The 381 series
13104-496: The southernmost and sunniest city of Germany, Freiburg , close to Alsace and Switzerland, being an ideal base for exploring the heights of the nearby Black Forest (e.g., for skiing in winter or for hiking in summer) with its traditional villages and the surrounding wine country of the Rhine Valley of South Baden. The countryside of the lush Upper Neckar valley (where Rottweil is famous for its Fastnacht carnival) and
13230-473: The southernmost part of Germany. The climate across the states varies. This is mostly due to a high amount of mountains and highlands inside of the state. Most parts in the western parts (Baden) lower than 500–800 metres (1,600–2,600 ft) enjoy an almost year round mild oceanic climate (cfb in Köppen classification). The climate in the eastern parts of the state is more continental. For instance, winters in
13356-672: The state capital Stuttgart , the University of Hohenheim , and the University of Stuttgart . Ludwigsburg is home to the renowned national film school Filmakademie Baden-Württemberg (Film Academy Baden-Wuerttemberg). The private International University in Germany was situated in Bruchsal , but closed in 2009. Another private university is located in Friedrichshafen, Zeppelin University . Furthermore, there are more than
13482-419: The state is among the most prosperous and wealthiest regions in Europe with a generally low unemployment rate historically. The state's economic performance benefits from and relies on its well-developed infrastructure. Apart from the city-states of Berlin , Bremen and Hamburg , Baden-Württemberg offers the fourth-shortest routes to trains and buses on average among all German states. Baden-Württemberg has
13608-528: The state's railway infrastructure. Passenger train services in Baden-Württemberg are operated partly by various subsidiaries of Deutsche Bahn , the national railway operator, such as DB Fernverkehr with its high-speed ICE , as well as IC trains ; and DB Regio , operating some regional train services in the state. Cross-border train services are also provided by French Railways ' TGV trains, as well as by Swiss Federal Railways and Austrian Federal Railways (including its Nightjet night trains). Since
13734-399: The tilt mechanisms are being removed to reduce weight and maintenance costs. Bombardier has since used updated versions of the LRC carriages for Amtrak 's Acela , the third generation of tilting ICE, the new generation of fast British trains ( Super Voyager ) and the experimental JetTrain . The Advanced Passenger Train (APT) was initially an experimental project by British Rail , with
13860-409: The tilt slightly, so that there was still some sensation of cornering. The APT-P trains were quietly reintroduced to service in mid-1984 and ran regularly for a year, the teething problems having been corrected. However, under an in-house engineering management who felt slighted and by-passed in a project they had not developed, there was no political or managerial will to continue the project by building
13986-469: The train entering limited service in December 1981 . Although eventually abandoned, the train was the pioneer of active tilt to negotiate tight curves at higher speeds than previous passive tilting trains. In the 1970s and 1980s, British Rail wanted an advanced fast train to negotiate Britain's twisting and winding Victorian-era rail system. Conventional trains were limited in speed due to the curvature of
14112-419: The train to derail . Tilting trains are designed to counteract this by tilting the carriages towards the inside of the curve, thus compensating for the g-force. The train may be constructed such that inertial forces cause the tilting ( passive tilt ), or it may have a computer-controlled powered mechanism ( active tilt ). The first passive tilting car design was built in the US in 1937, and an improved version
14238-455: The train to negotiate curves up to 35% faster than conventional Intercity trains (locomotive plus coaches). The body, which exploits large aluminium extrusion technology, has substantial modularity and allows for extremely low axle weight, whilst fully respecting the highest safety standards, and allows the best exploitation of the space with different loading gauges. ETR 460 was built in only 10 units. Improved versions include ETR 470 for
14364-440: The train, changed some of the prime and proven engineering aspects. For example, they changed the active tilt mechanism to pneumatic , rather than the well-developed and proven hydraulics . The trains were introduced in 1981, but almost immediately taken out of service. During initial tests, some passengers complained of being nauseous due to the tilting motion. Subsequently, it was learned that this could be prevented by reducing
14490-629: The treaty, the maintenance of the entire line was the sole responsibility of the Royal Württemberg Railway. In 1922, the Zollernalb Railway between Tübingen and Sigmaringen had a total of 22 stations served by passenger trains, including a station called Zollern for the royal visitors to the Hohenzollern Castle . Over the next several decades the less frequented stations were closed. During 1997, modern diesel multiple units with strong acceleration were introduced on
14616-470: The urban cores ( tram-trains ). Tilting train A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks . As a train (or other vehicle) rounds a curve at speed, objects inside the train experience centrifugal force . This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest, and standing passengers to lose their balance. In such excessive speeds, it could even cause
14742-439: The way the carriages always swung outward, they placed more weight on the outside of the curve, which limited their improvement in cornering speed to about 20%. Starting in the late 1960s, British Rail also began experiments with its Advanced Passenger Train (APT) which pioneered the active-tilt concept, along with in-cab signalling, to permit High Speed Rail services on conventional tracks. The APT family used hydraulic rams on
14868-741: The western border as well as large portions of the southern border. The Black Forest (Schwarzwald), the central mountain range of the state, rises east of the Upper Rhine valley . The high plateau of the Swabian Alb , between the Neckar, the Black Forest, and the Danube, is an essential European watershed . Baden-Württemberg shares Lake Constance (Bodensee, also known regionally as the Swabian Sea) with Switzerland, Austria and Bavaria,
14994-461: Was built in 1939. The beginning of World War II ended development. Talgo introduced a version based on their articulated bogie design in 1950s, and this concept was used on a number of commercial services. Among these was the UAC TurboTrain , which was the first (albeit short-lived) tilting train to enter commercial service in 1968 in the US and Canada. Japan similarly experimented, from
15120-476: Was commissioned. While classes 401 to 403 (without tilting technology) were to cover the newly built or modernized high speed lines at up to 300 km/h (186 mph) (ICE 3 Class 403), Classes 411 and 415 with maximum speed of 230 km/h (143 mph) were designed for older twisting main lines. A total of 60 Class 411 and 11 Class 415 (shorter version) have been built so far. Both classes worked reliably until late 2008 when cracks were found on an axle during
15246-490: Was delivered to Trenitalia and Cisalpino as the ETR 600 and the ETR 610 from 2006. Italian Pendolinos and their derivatives still represent the most popular solution for active tilting in passenger trains. The technology still in use today is almost the same developed by Fiat Ferroviaria in the 1960s-70s. The British version of the Pendolino, the British Rail Class 390 , is a 225 km/h (140 mph) electric tilting train operated by Avanti West Coast . It runs on
15372-432: Was dominated by class 50 locomotives , which also hauled a few passenger services until 1975. With the end of steam locomotives on the Zollernalb Railway, operations were taken over by class 215 and class 211/212 diesel locomotives and Uerdingen railbuses ; locomotive-hauled passenger trains included Silberling carriages or four-axle Umbau-Wagens, which now operated under the brand name of Allgäu-Zollernbahn . In 1988,
15498-606: Was occupied by the United States . The new artificial borders were a consequence of France requesting its own occupation zone in Germany after World War II, and the Americans' wish to keep the A8 motorway , which spans east-west across northern Baden and northern Württemberg, wholly within their occupation zone. In 1949, each state became a founding member of the Federal Republic of Germany (West Germany), with Article 118 of
15624-547: Was powered by gas turbines; the APT-P (P for prototype) was electric. With no tilting, the train was developed to break the British rail speed record. Tilting trains using passive tilt were not new, but it was uncommon and not widely implemented. The engineers decided that active tilt was the key to negotiating curves at much higher speeds. The train had hydro-dynamic brakes and lightweight articulated bodies, with two power cars in
15750-489: Was the UAC TurboTrain , used by Canadian National in 1968. Some figures have considered it to be the first tilting train in service in the world. It provided daily service between Montreal and Toronto at speeds of 160 km/h (99 mph), until it was replaced by Bombardier LRC trains in 1982, reaching the maximum speed of 225 km/h (140 mph) during Canadian trials. TurboTrains were also operated by Amtrak between Boston and New York. The UAC Turbos had
15876-607: Was the first commercial tilting EMU in Asia, entering service in 1973 on the Shinano limited express services that operated on the hilly Chūō Main Line . The sets remained in operation until June 2024, when the last regularly scheduled trains ended on the Yakumo service. During the final years of the Japanese National Railways , experimentation on mechanically-regulated passive tilt -
