DSB Class MF
The DSB Class MF is a Danish-built high-comfort medium/long distance diesel multiple-unit train. The sets were built by ABB Scandia (later purchased by Adtranz, which itself was subsequently acquired by Bombardier Transportation) in Randers. This train model has been operating in Denmark, Sweden and Israel since 1990. The name IC3 indicates simply that it is a three-carriage InterCity trainset. An electrically powered four-carriage version, the IR4 was introduced between 1995 and 1998. General overview The IC3 is a wide articulated train made of light alloy with Jacobs bogies shared between carriages. There are two engines in each end of the front and rear carriages, central car has none, giving a total of . The efficient mechanical transmissions with multiple gear ratios and high power for the tare weight give the IC3 good acceleration capabilities. The short distances between stations on inter-city routes in Denmark makes acceleration more important than high top speed, ...

Frederikshavn Station
Frederikshavn railway station (Danish: ''Frederikshavn Station'' or ''Frederikshavn Banegård'') is a railway station serving the town of Frederikshavn in Vendsyssel, Denmark. The station is the terminus of the Vendsyssel railway line from Aalborg to Frederikshavn as well as the Skagen railway line from Frederikshavn to Skagen. The station opened in 1871 and was moved to its current location in 1979. It offers direct regional rail services to Aalborg as well as local train services to Skagen. The train services are currently operated by the local railway company Nordjyske Jernbaner. History The first station in Frederikshavn opened on 15 August 1871 as the terminal station of the new Vendsyssel railway line from Nørresundby to Frederikshavn. On 7 January 1879, at the opening of the Limfjord Railway Bridge which connected Nørresundby and Aalborg across the Limfjord, the line was connected with Aalborg station, the Randers–Aalborg railway line and the rest of Denmark's railw ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Train
In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. Trains are designed to a certain Track gauge, gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Trains have their roots in wagonways, which used railway tracks and were Horsecar, powered by horses or Cable railway, pulled by cables. Following the invention of the steam locomotive in the United Kingdom in 1804, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever pos ...

Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 train s ...

Punktförmige Zugbeeinflussung
PZB or Indusi is an intermittent cab signalling system and train protection system used in Germany, Austria, Slovenia, Croatia, Romania, Israel, Serbia, on two lines in Hungary, on the Tyne and Wear Metro in the United Kingdom, and formerly on the Trillium Line in Canada. Developed in Germany, the historic short name Indusi was derived from German ("inductive train protection"). Later generations of the system were named PZB (short for German , literally "punctiform train influencing", translated as "intermittent train protection" or officially "intermittent automatic train running control"), highlighting that the PZB/Indusi system is a family of intermittent train control systems, in comparison with the continuous train control systems including LZB (German , literally "linear train influencing") that were introduced at the time. Originally, Indusi provided warnings and enforced braking only if the warning was not acknowledged (similar to traditional automatic train stop). The ...

European Train Control System
The European Train Control System (ETCS) is the signalling and control component of the European Rail Traffic Management System (ERTMS). It is a replacement for legacy train protection systems and designed to replace the many incompatible safety systems currently used by European railways. The standard was also adopted outside Europe and is an option for worldwide application. In technical terms it is a type of positive train control (PTC). ETCS is implemented with standard trackside equipment and unified controlling equipment within the train cab. In its advanced form, all lineside information is passed to the driver wirelessly inside the cab, removing the need for lineside signals watched by the driver. This will give the foundation for a later to be defined automatic train operation. Trackside equipment aims to exchange information with the vehicle for safely supervising train circulation. The information exchanged between track and trains can be either continuous or int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Rail Traffic Management System
The European Rail Traffic Management System (ERTMS) is the system of standards for management and interoperation of signalling for railways by the European Union (EU). It is conducted by the European Union Agency for Railways (ERA) and is the organisational umbrella for the separately managed parts of * GSM–R (communication), * European Train Control System (ETCS, signalling), * European Train Management Layer (ETML, payload management) The main target of ERTMS is to promote the interoperability of trains in the EU. It aims to greatly enhance safety, increase efficiency of train transports and enhance cross-border interoperability of rail transport in Europe. This is done by replacing former national signalling equipment and operational procedures with a single new Europe-wide standard for train control and command systems. The development process was started with the technical foundations for communication (GSM-R) and signalling (ETCS). Both are well established and in adva ...

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. Over time, there have been many different safety systems labelled as "automatic train control". 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 especially co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electromagnetic 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 ...
