126-726: The Tübingen Hbf–Sigmaringen railway (also known in German as the Zollernalbbahn —Zollernalb Railway) is a main line railway in the German State of Baden-Württemberg . It runs from Tübingen to Sigmaringen . It is consistently single track and non-electrified, but it is equipped for the operation of tilting trains . Deutsche Bahn calls the Zollernalb line the Zollern-Alb-Bahn 1 (ZAB 1) to distinguish it from

252-616: A Frankish invasion led by Clovis I . The Holy Roman Empire was later established. 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

504-601: A domestic invention, the Talgo , and developed it into a reliable high-speed train for a low-traffic-density railway. British Rail invested heavily in tilting-train technology to overcome the limitations of a rail network located in space-constrained built-up areas. Italy's Trenitalia and the Japan National Railways have used tilting technology to speed express trains on conventional tracks through mountainous terrain. Tilting trains are meant to help reduce

630-575: A dozen Fachhochschulen , i.e., universities of applied sciences, as well as Pädagogische Hochschulen , i.e., teacher training colleges, and other institutions of tertiary education in Baden-Württemberg. 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

882-481: A major part of the transport infrastructure in Baden-Württemberg. As of 2017, the main standard gauge railway network managed by DB Netz consists of about 3,350 kilometres (2,080 mi) of railway lines connecting all major settlements of the state, with about 6,500 trains operating every day. As part of high-speed rail in Germany , the Mannheim–Stuttgart and Stuttgart–Ulm high-speed lines were built, and

1008-521: A niche for speciality pork products in the rapidly growing English cities, especially those in the industrial centre and North. Many married local women and sent word home that a good living could be made in England; others followed. In the late 19th and early 20th centuries, numerous people emigrated from this primarily rural area to the United States for economic reasons. At the beginning of

1134-432: A number of wheel sets, and again wheels and axles had to be replaced. Today Class 612 is back to tilting operation and forms the backbone of DB's fast regional service on non-electrified lines. Additional units were sold to Croatia , where they are used for InterCity services. In 1999 DB was able to use tilting technology for its InterCityExpress services, when with class 411 and 415 an electric high-speed tilting train

1260-417: A passive tilt mechanism based on a four-bar arrangement, and they inspired the second generation of TALGO trains. 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,

1512-674: 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

1638-528: A sovereign country (2020), it would have an economy comparable to that of Sweden in terms of nominal gross domestic product (GDP). A number of well-known enterprises are headquartered in the state, for example Mercedes-Benz Group , Porsche , Robert Bosch GmbH (automobile industry), Carl Zeiss AG (optics), SAP (Europe's most valuable brand as well as the largest non-American software enterprise) and Heidelberger Druckmaschinen (precision mechanical engineering). Despite this, Baden-Württemberg's economy

1764-586: A total area of nearly 35,752 km (13,804 sq mi), it is the third-largest German state by both area (behind Bavaria and Lower Saxony ) and population (behind North Rhine-Westphalia and Bavaria). As a federated state , Baden-Württemberg is a partly-sovereign parliamentary republic . The largest city in Baden-Württemberg is the state capital of Stuttgart , followed by Mannheim and Karlsruhe . Other major cities are Freiburg im Breisgau , Heidelberg , Heilbronn , Pforzheim , Reutlingen , Tübingen , and Ulm . Modern Baden-Württemberg includes

1890-646: A tourist magnet in all major towns, the largest being in Stuttgart during the three weeks before Christmas. The Bertha Benz Memorial Route is a 194 km signposted scenic route from Mannheim via Heidelberg and Wiesloch to Pforzheim and back, which follows the route of the world's first long-distance journey by automobile which Bertha Benz undertook in August 1888. Baden-Württemberg also contains Europa-Park in Rust . The largest theme park in Germany, and

2016-465: Is a popular holiday destination. Main sights include the capital and biggest city, Stuttgart , modern and historical at the same time, with its urban architecture and atmosphere (and famously, its inner-city parks and historic Wilhelma zoo), its castles (such as Castle Solitude ), its museums as well as a rich cultural programme (theatre, opera) and mineral spring baths in Bad Cannstatt (also

2142-626: Is dominated by small and medium-sized enterprises, like most companies in German-speaking countries are . 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

2268-402: Is initiated by computers, which 'force' train bodies to tilt at specific angles based on track information. This information could be stored on board or detected using a sensor at the front of the train or using Automatic train stop beacons. The slight delay in reacting to this information leads to a short period of sideways force while the cars react. It was found that when the cars tilt just at

2394-509: Is the Landtag , located in Stuttgart. The state government is currently formed by a Greens - CDU coalition as the third cabinet of Minister-President Winfried Kretschmann (Greens). 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

2646-536: The Atchison, Topeka and Santa Fe Railway that year. The company built another three pre-production models in 1939, using more conventional fore-and-aft bogies, and these saw some use with the San Diegan , among others. Mounted on high springs, the car tilted inwards on curves to counterbalance the cant deficiency with the induced centrifugal force. The opening of World War II prevented any immediate orders, and

2772-798: 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

3150-642: The German constitution providing an accession procedure. On 9 December 1951, a referendum was held in Württemberg-Baden, Württemberg-Hohenzollern and (South) Baden over a possible merger, or the restoration of the former pre-war states. There was strong support for the merger in Württemberg and Hohenzollern, but opposition in Baden. While a majority in the historic area of Baden (52%) voted to restore

3276-598: The Hamburg – Copenhagen route. Since 2018 and 2021, two units are in operation as the advanced TrainLab  [ de ] test train. In 1966, a consortium of Canadian industrial firms began considering a conventionally-powered competitor to the TurboTrain, eventually emerging as the LRC (Light, Rapid, Comfortable) in the early 1970s. This design also used an active-tilt system, but one of very different form than

3402-615: The Hohenzollerischen Landesbahn (HzL). On 2 January 2002, HzL took over wagonload traffic on the Zollernalb line and other lines in the region. For several years, there have been proposals to integrate the Tübingen–Albstadt-Ebingen section of the line (in association with the reactivation of the Talgang Railway —Talgangbahn—to Onstmettingen) in the proposed Regionalstadtbahn Neckar-Alb on

3528-649: The Karlsruhe model . Baden-W%C3%BCrttemberg Baden-Württemberg ( / ˌ b ɑː d ən ˈ v ɜːr t ə m b ɜːr ɡ / BAH -dən VURT -əm-burg ; German: [ˌbaːdn̩ ˈvʏʁtəmbɛʁk] ), commonly shortened to BW or BaWü , is a German state ( Land ) in Southwest Germany , east of the Rhine , which forms the southern part of Germany's western border with France . With more than 11.07 million inhabitants as of 2019 across

3654-652: The Karlsruhe–Basel high-speed line , paralleling the traditional Mannheim–Karlsruhe–Basel railway , is currently under construction. In and around Stuttgart, the old terminal station is currently being replaced with an underground through station as part of the controversial Stuttgart 21 project. Local branch lines of around 860 kilometres (530 mi), managed by the state-owned SWEG and Hohenzollerische Landesbahn (HzL), Karlsruhe-owned Albtal-Verkehrs-Gesellschaft (AVG), private Württembergische Eisenbahn (WEG) and other smaller rail infrastructure operators, complete

3780-614: The Odakyu 50000 series VSE , a luxurious sightseeing express train with active suspension introduced not to increase speeds but to enhance ride comfort; and even cheap enough to be applied to commuter stock, such as JR Hokkaido 's KiHa 201 series , which improved speeds and frequencies on Sapporo 's partly non-electrified suburban railway system. This is also one of the only applications of tilting technology on 'metro-style' commuter trains to date. . More modern and more numerous examples of active suspension and pneumatic tilting trains, include

3906-840: The Republic of Baden , the Free People's State of Württemberg and the Free State of Prussia . Following Adolf Hitler becoming chancellor of Germany in 1933, the democratic institutions of Baden, Württemberg and Prussia were abolished as part of the Gleichschaltung . After World War II, the Allies established three states in the territory of modern-day Baden-Württemberg: (South) Baden , Württemberg-Baden and Württemberg-Hohenzollern . Baden and Württemberg-Hohenzollern were occupied by France , while Württemberg-Baden

4032-628: The Swabian Jura mountain range. The Black Forest formed part of the border between Baden and Württemberg. In 100 AD, the Roman Empire invaded and occupied Württemberg, constructing a limes along its northern borders. Over the course of the third century AD, the Alemanni forced the Romans to retreat west beyond the Rhine and Danube rivers. In 496 AD the Alemanni were defeated by

4158-476: The T originally did not stand for tilting but for Triebwagen (self-propelled car), as DB's marketing department at first deemed the top speed too low for assignment of the InterCityExpress brand and therefore planned to refer to this class as IC-T (InterCity-Triebwagen). Rather luckless was Class 411/415's adaptation for diesel services. In 2001, a total of 20 units were commissioned for use on

4284-683: The Talgo Pendular . Talgo is currently in its 21st generation of production. Talgo trains are in service in various parts of Europe, and built under licence in Latin America and Asia. In North America, Amtrak uses Talgo trains in its Cascades service in the Northwest. The first Talgo tilting series were the "pendular" ones from 400 series onwards. The first tilting train to enter into regular service in North America

4410-504: The Tōkaidō Shinkansen , allowing the trains to maintain 270 km/h (168 mph) even on 2,500 m (8,200 ft) radius curves that previously had a maximum speed of 255 km/h (158 mph). Many high-speed trainsets are designed to operate on purpose-built high-speed lines and then continue their journeys on legacy lines, upgraded or not. Where the legacy lines justify it, a tilting train may operate at higher speeds on

4536-486: The West Coast Main Line ( London Euston to Glasgow Central , Liverpool Lime Street and Manchester Piccadilly ). Class 390s commenced operation in 2001 with only one being in a major derailment. Due to signalling constraints, Class 390s are limited to 201 km/h (125 mph) in regular service. Japan was an early adopter of tilting trains and continues to use them on many express services. Due to

4662-559: The Zollern-Alb-Bahn 2 , the trunk line of the Hohenzollerische Landesbahn . The line starts at 320 metres above sea level, when it leaves Tübingen Central Station to the west, with some services from Stuttgart running on from the Neckar-Alb Railway , and immediately swings to the south along the valley of Steinlach , which it follows to Bodelshausen . In Hechingen , the station is located north of

4788-454: The highest exports (2019) and third-highest imports (2020), the second-lowest unemployment rate with 4.3% (March 2021), the most patents pending per capita (2020), the second-highest absolute and highest relative number of companies considered " hidden champions ", and the highest absolute and relative research and development expenditure (2017) among all states in Germany, as well as the highest measured Innovationsindex (2012), making it

Part of the Four Motors for Europe and located in the Blue Banana , some of the largest German companies are headquartered in Baden-Württemberg, including Mercedes-Benz Group , Schwarz Group , Porsche , Bosch and SAP . The sobriquet Ländle , a diminutive of the word Land in

5040-409: The 'limited express' EMUs E353 series for JR East. Deutsche Bundesbahn started tests with tilting trains in Germany with its Class 634 in 1967 when some Class 624 DMUs were equipped with passive tilting systems. As the passengers experienced motion sickness, the tilting technology was disabled and later removed. The tests continued with the prototypes of the following Class 614 units, but due to

5166-560: The 1.2 million persons employed in the industry. The Mittelstand or mid-sized company model is the backbone of the Baden-Württemberg economy. Medium-sized businesses and a tradition of branching into different industrial sectors have ensured specialisation over a wide range. A fifth of the "old" Federal Republic's industrial gross value added is generated by Baden-Württemberg. Turnover for manufacturing in 2003 exceeded 240,000 million, 43% of which came from exports. The region depends to some extent on global economic developments, though

5292-445: The 1990s, the around 120 individual regional train services in Baden-Württemberg have been managed by the state-owned Nahverkehrsgesellschaft Baden-Württemberg (NVBW), which has started to commercially tender out these train operations. DB Regio, SWEG, HzL, AVG and WEG have been joined in operating regional trains by Abellio , Agilis , Bodensee-Oberschwaben-Bahn , Go-Ahead , SBB , Schwäbische Alb-Bahn and VIAS , which entered

5418-621: The 20th century, the territory of modern-day Baden-Württemberg consisted of the Grand Duchy of Baden , the Kingdom of Württemberg and the province of Hohenzollern of the Kingdom of Prussia . Since 1871, these had been part of the German Empire . In the aftermath of World War I and as part of the German revolution of 1918 , the monarchs of Baden, Württemberg and Prussia were deposed, and these states became democratic republics:

5544-709: The 8000 series serves as the basis of the Electric Tilt Train built for Queensland Rail 's Cape Gauge network. The 885 series, built as part of the Hitachi A-train family, serves as the basis of the Taiwanese TEMU1000 series tilting EMU for Taroko Express services, and some non-tilting variants including the British Rail Class 395 and British Rail Class 801 . Later developments in pneumatic active suspension - based on

5670-536: The ALn 668 1999 diesel car, provided with tilting seats to test the effects of active tilting technologies. The first working prototype using a tilting carbody was ETR Y 0160, an electrically powered car launched by FIAT in 1969. This was the first to be christened Pendolino . This design led to the construction of an entire EMU in 1975, the ETR 401 , built in two units by FIAT. One was put into public service on 2 July 1976 on

5796-543: The APT. The carriages rode on two C-shaped channels mounted across the top of the bogies. Tilt was accomplished by rams that pushed the bottom of the carriage side to side along these channels. Amtrak experimented with the LRC in 1980, but retired it seven years later. In Canada, it entered service in 1981, beating the APT into service and becoming the first operational active-tilt system. The LRC carriages remain in use today, although

5922-711: The Christian Democrats and centre-right Free Democrats (FDP) coalition with an alliance of the Greens and Social Democrats (SPD), which secured a four-seat majority in the state parliament. The alliance elected the Greens-led first Kretschmann cabinet under Winfried Kretschmann because the Greens had surprisingly won 36 seats, one more than the Social Democrats' 35 seats. In the 2016 election ,

6048-588: The Danube, in Donaueschingen is often referred to as the "source of the Danube" ( Donauquelle ). Hydrologically, the source of the Danube is the source of the Breg as the larger of the two formative streams, which rises near Furtwangen . The forests in this region are home to common pests such as Melolontha Hippocastrani , that cause damage to the foliage and soil. Baden-Württemberg is – along with Bavaria –

6174-517: The ETR 460 introduced several innovations, such as more powerful AC asynchronous motors. The pistons actuating the tilting action were placed in the bogie instead of on the carbody sides: this permitted the reorganisation of the vestibules and passenger compartment areas, improving comfort. The bogie-to-body connection is extremely simple and easy to build, with maintenance advantages. ETR 460 keeps axle load to an extremely low level (14.5 ton/axle), to allow

6300-513: The Federal Constitutional Court decided in 1969 that another referendum should be held by 30 June 1970. The referendum in the historic area of Baden was finally held on 7 June 1970, with 81.9% of the voters voting in favour of the merger of Baden and Württemberg. Baden-Württemberg shares borders with the German states of Rhineland-Palatinate , Hesse , and Bavaria , and also shares borders with France ( Alsace , within

6426-412: The German state with the third-highest gross regional product (GRP) as of 2019 (behind North Rhine-Westphalia and Bavaria ) with €524,325 billion (around US$ 636.268 billion). Baden-Württemberg also has the most employees (233,296) in the automotive industry of all German states as of 2018 , as well as the third-highest number of motor vehicles of all German states (2020). If Baden-Württemberg were

6552-511: The Italian government in the project in the mid 1980s, and the introduction of new technologies, led to the revision of the project with the ETR 401 with electronic systems, that led to the introduction of the slightly more advanced ETR 450 , the first Pendolino to enter regular service in the world. Characterized by an 8-car configuration, and a maximum tilt reduced to 8° from the 10° of the ETR 401, for safety and comfort reasons, ETR 450 could run

6678-598: The Italo-Swiss Cisalpino company, the ETR 460 France, later called as ETR 463, used by FS to the route Milan Lione, and the ETR 480 , used by Trenitalia under AC-powered Italian high speed lines. A total of 34 EMUs of the ETR 460/470/480 series were built for FS. The development of the Pendolino technology continued in the Italian factories of Alstom and the next generation, the New Pendolino ,

6804-415: The Regionalbahn services overlap and between Albstadt–Ebingen and Aulendorf Regionalbahn and Interregio-Express services also overlap, giving an approximate hourly service, so that from Monday to Friday all places except Strassberg-Winterlingen and Storzingen are served at least hourly. Extra trains run especially in the peak hours, for school traffic and on Sunday evening, some of which operate on only part of

6930-418: The Rome- Ancona (later extended to Rimini ) line, operated by Italian State Railways . Between Roma and Ancona (km. 295), the train took 2 hours 50 minutes, while ordinary trains took 3 hours 30 minutes. The train had four cars and was mostly considered a travelling laboratory for the new technology. Initially the ETR 401 was conceived as the first of a series of four trains, but the government lost interest to

7056-472: The Rome-Milan line in under four hours, at speeds up to 250 km/h (160 mph). Passenger numbers increased from 220,000 in 1988 to 2.2 million in 1993. 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,

7182-524: The Zollernalb Railway for the operation of tilting trains , which was completed in 2001, included the construction of new platforms and underpasses at the stations of Dußlingen, Mössingen, Bisingen and Albstadt-Ebingen. Until early 1971, Deutsche Bundesbahn passenger services were mainly operated by P 8 steam locomotives based in Tübingen, partly in double traction because of the grades, hauling three and four axle Umbau-Wagens or Silberling carriages, class 64 locomotives were also used. Freight traffic

7308-416: The again unsatisfying results the serial types were delivered without tilting system. Another early train with tilting technology was Deutsche Bundesbahn 's Class 403 (today this number is used by ICE 3 ) high speed EMU. Following its InterCity services until 1979, it was also used for airport transfers between Düsseldorf and Frankfurt (see also: AiRail Service ). Class 403 was able to tilt 4°, but

7434-412: The bearing axis, and this caused them to naturally pendulum outward on curves. 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

7560-516: The beginning of the curves instead of while they are making the turns, there was no motion sickness. 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

7686-403: The bottoms of the carriages to tilt them, rotating them around their centre point rather than swinging outward. This had the advantage of keeping the carriage centred over the bogies, which reduced load on the rails, and could be turned off when navigating switches. Due to lengthy political delays, the APT did not begin service testing until 1979, entering limited scheduled service in December 1981,

7812-401: The centre of the train. When the prototypes were built, worked and proven, the engineering development team was disbanded and the trains handed over to British Rail's in-house engineering department to build. The developing engineers moved on to different fields while British Rail engineered the train into a production model. The BR engineers, who had little to no involvement in the development of

7938-413: The city and above the station of the Hohenzollerische Landesbahn ; there is a track connecting the lines. After leaving Hechingen station, the Zollernalb Railway runs around the town to the south and continues to run to the southwest to Balingen , where it reaches a height of 517 m. South of Balingen the line runs to the southeast, up the valley of the Eyach and overcomes a long climb of 1 in 45, reaching

8064-412: The city of Ulm are colder than in Berlin. While winters in the warmest areas often lack snow, the Black Forest , Swabian Alb and the Alps tend to get snow frequently, especially in areas of high elevation. Summers here have more rain than in the valleys, but winters tend to have more sun. Due to the differences of the landscapes, average annual temperatures reach from only 5 °C (41 °F) in

8190-526: The concept was not revived in the post-war era. In 1956, SNCF experimented with a self-propelled pendulum car, which also relied on centrifugal force. 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

8316-530: The country's mountainous Cape gauge (1,067mm) railway system soon became apparent and since then these 'semi-active' tilting trains have seen widespread use on limited-express trains throughout the archipelago. Particularly well-known diesel and electric examples of this generation of tilting trains include JR Hokkaido 's KiHa 281 series , JR East 's E351 series , JR Central 's 383 series , JR Shikoku 's 8000 series , and JR Kyushu 's 885 series . This generation of designs has seen some popularity overseas -

8442-467: The early 1950s, the Spanish National Railway, Renfe , experimented with passenger cars that combined the Talgo bogie with a new passive tilting system. 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

8568-540: The effects of centrifugal force on the human body, but they can still cause nausea , a problem that was widely seen on early "passive" tilting trains that exactly balanced the outward force. 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

12852-431: The site of a Roman Castra ); it is the only major city in Germany with vineyards in an urban territory. 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 -
