X 2000
X 2000, officially designated X2, is an electric high-speed tilting train operated by SJ in Sweden. It has a top commercial speed of 200 km/h (124 mph) and a top design speed of 210 km/h (130 mph) but has achieved a maximum speed of 276 km/h (171 mph) in tests. It primarily serves major routes, including Stockholm–Gothenburg and Stockholm–Malmö–Copenhagen. The X2 project began in 1969 as a collaboration between Kalmar Verkstad, Swedish State Railways (SJ), and ASEA. In 1986, SJ placed an order for 20 sets of a new type of train. Asea was responsible for manufacturing the electrical components, while Kalmar Verkstad (Statsföretag) was responsible for the mechanical design and manufacturing. Ultimately, a total of 44 train sets were built. The trains, designed and manufactured in Kalmar, Sweden, were launched in 1990 as a first-class only train with a meal included in the ticket price, and free use of the train's fax machine. From 1995 second class was introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stockholm Central Station
Stockholm Central Station (), is the main Train station, railway station in Stockholm, and largest railway station in Sweden in terms of passenger numbers and train traffic. It is located in the Norrmalm district of central Stockholm on Vasagatan, Stockholm, Vasagatan, extending from Vattugatan in the south to Kungsbron in the north. The station opened on 18 July 1871. Since 2001, the station building has been owned and managed by Jernhusen, while the platforms and tracks are overseen by the Swedish Transport Administration. The station code for Stockholm Central is ''Cst.'' Over the years, the station has undergone numerous renovations and expansions. The most significant changes took place between 1925 and 1928 when the large central hall, designed by architect Folke Zettervall, was added. In the mid-1950s, the station was integrated with the Stockholm Metro through a new underground passageway and concourse to T-Centralen. The building has been designated as a heritage site s ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Sweden
Sweden, formally the Kingdom of Sweden, is a Nordic countries, Nordic country located on the Scandinavian Peninsula in Northern Europe. It borders Norway to the west and north, and Finland to the east. At , Sweden is the largest Nordic country by both area and population, and is the List of European countries by area, fifth-largest country in Europe. Its capital and largest city is Stockholm. Sweden has a population of 10.6 million, and a low population density of ; 88% of Swedes reside in urban areas. They are mostly in the central and southern half of the country. Sweden's urban areas together cover 1.5% of its land area. Sweden has a diverse Climate of Sweden, climate owing to the length of the country, which ranges from 55th parallel north, 55°N to 69th parallel north, 69°N. Sweden has been inhabited since Prehistoric Sweden, prehistoric times around 12,000 BC. The inhabitants emerged as the Geats () and Swedes (tribe), Swedes (), who formed part of the sea-faring peopl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 generates longitudinal force that can cause the train to physically tilt on one side, eventually causing it to Derailment, 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 Pendulum car, tilting car design was built in the US in 1937, and an improved version was built in 1939. The beginning of World War II ended development. ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages. However, electrically powered single-unit railcars are also generally classed as EMUs. The vast majority of EMUs are passenger trains but versions also exist for carrying mail. EMUs are popular on intercity, commuter, and suburban rail networks around the world due to their fast acceleration and pollution-free operation, and are used on most rapid-transit systems. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting ...

ZUB 123
The ZUB 1xx system is a family of train protection systems produced by Siemens. Its ZUB balises were deployed in the ZUB 121 train protection system in the Swiss railway network, in the ZUB 122 tilting control system in the German railway network, and in the ZUB 123 train protection system in the Danish railway network. Some of these were adapted for other railway lines before the next generation ZUB 2xx family was introduced which is based on Eurobalises - the earlier ZUB balises are not compatible with those. History The German LZB was created in 1965 and it was deployed on high-speed lines throughout the 1970s. However, with its signal wire along the complete length of a track it was considered too expensive in order to replace the traditional PZB inductive train stops that have been put along with line-side signals. In the 1980s the manufacturers of railway signaling systems developed electronic versions that could be deployed in the same pattern as the traditional trai ...

Automatic Train Control
Automatic train control (ATC) is a general class of train protection systems for railways that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger. ATC systems tend to integrate various cab signalling technologies and they use more granular deceleration patterns in lieu of the rigid stops encountered with the older automatic train stop (ATS) technology. ATC can also be used with automatic train operation (ATO) and is usually considered to be the safety-critical part of a railway system. There have been numerous different safety systems referred to as "automatic train control" over time. The first experimental apparatus was installed on the Henley branch line in January 1906 by the Great Western Railway, although it would now be referred to as an automatic warning system (AWS) because the driver retained full command of braking. The term is especi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Brake
A magnetic track brake (Mg brake) is a brake for rail vehicles. It consists of brake magnets, pole shoes, a suspension, a power transmission and, in the case of mainline railroads, a track rod. When current flows through the magnet coil, the magnet is attracted to the rail, which presses the pole shoes against the rail, thereby decelerating the vehicle. While brakes such as disc brakes or shoe brakes depend on the frictional connection between wheel and rail, the magnetic track brake acts directly on the rail. Therefore, its brake effect is not limited by wheel-rail contact. Thus, environmental factors such as wetness or contamination of the rail have less influence on the brake force. Usage Magnetic track brakes are used on rail vehicles in addition to the primary, wheel-effective brake systems. As an additional brake system, they help to ensure that the prescribed brake distances of rail vehicles can be complied with. Since magnetic track brakes always act unregulated an ...

Slippery Rail
Slippery rail, or low railhead adhesion, is a condition of Rail transport, railways (railroads) where contamination of the railhead reduces the traction between the wheel and the rail. This can lead to Locomotive wheelslip, wheelslip when the train is taking power, and wheelslide when the train is braking. One common cause of contamination is fallen leaf, leaves that adhere to the railhead (top surface) of railway tracks. The condition results in significant reduction in friction between train wheels and rails, and in extreme cases can render the track temporarily unusable. In Britain, the situation is colloquially referred to as "leaves on the line". Low adhesion caused by weather Railhead contamination caused by weather conditions can occur at any time of year. The leaf fall season causes the most disruption to rail operations. In heavily deciduous forested areas like the American Mid-Atlantic States, Mid-Atlantic states, New England, many parts of Europe including the UK, and ...

Regenerative Brake
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can be either used immediately or stored until needed. Typically, regenerative brakes work by driving an electric motor in reverse to recapture energy that would otherwise be lost as heat during braking, effectively turning the traction motor into a generator. Feeding power backwards through the system like this allows the energy harvested from deceleration to resupply an energy storage solution such as a battery or a capacitor. Once stored, this power can then be later used to aid forward propulsion. Because of the electrified vehicle architecture required for such a braking system, automotive regenerative brakes are most commonly found on hybrid and electric vehicles. This method contrasts with conventional braking systems, where excess kinetic energy is converted to unwanted and wasted heat due to friction ...

Railway Airbrake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, referred to as a ''straight air system'', compressed air is directed to a ''brake cylinder'', causing its piston to apply force to mechanical linkage, which linkage is conventionally referred to as the ''brake rigging'' (see illustratio ...
