Automatische Treinbeïnvloeding
Automatische TreinBeïnvloeding or ATB (English: Automatic Train Control) is a Dutch train protection system first developed in the 1950s. Its installation was spurred by the Harmelen train disaster of 1962. ATB operates by the train collecting electrical signals from line-side apparatus and will override the driver's controls in the following situations: * a) failure to reduce speed at a caution signal (ATB will slow the train sufficiently to stop at the next signal). * b) failure to observe speed limit (ATB makes an immediate emergency brake application) ATB-EG ATB-EG ''(''ATB Eerste Generatie ''English: ATB First Generation'') is based on the American Pulse Code Cab Signaling system. It is installed on all major Dutch rail lines Technical overview ATB-EG controls 5 speeds: 40 km/h, 60 km/h, 80 km/h, 130 km/h and 140 km/h. Just like Pulse Code Cab Signaling the system works by sending pulses along the AC track circuit. When the circuit is closed by ...

Light-emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (U ...

Zwolle–Almelo Railway
The Zwolle–Almelo railway is a regional railway line, that connects Zwolle with Almelo, Netherlands. History The railway was part of the third national construction period of railways in the Netherlands. This last phase of railway construction saw mostly the appearance of local and regional railways. With the Zwolle–Almelo railway, Zwolle and the northernmost provinces were offered a direct link to the Almelo-Salzbergen railway. Route The railway leaves Zwolle in southeastern direction and continues in a straight line to the town of Raalte. There it curves towards Nijverdal, where the railway continues underground for 1500 meters, as part of the Salland-Twente tunnel. It then continues to Wierden, where it merges with the Deventer-Almelo railway and continues to Almelo. Train services The entire length of the railway is served Sprinter services between Zwolle and Enschede, calling at every station. Since 10 December 2017 an express train runs between Enschede and Raal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backward Compatibility
Backward compatibility (sometimes known as backwards compatibility) is a property of an operating system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially in telecommunications and computing. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking" backward compatibility. A complementary concept is forward compatibility. A design that is forward-compatible usually has a roadmap for compatibility with future standards and products. A related term from programming jargon is hysterical reasons or hysterical raisins (near-homophones for "historical reasons"), as the purpose of some software features may be solely to support older hardware or software versions. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM radio in stereo. FM radio was initially mono, with only one audio channel repre ...

Fail-safe
In engineering, a fail-safe is a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause minimal or no harm to other equipment, to the environment or to people. Unlike inherent safety to a particular hazard, a system being "fail-safe" does not mean that failure is impossible or improbable, but rather that the system's design prevents or mitigates unsafe consequences of the system's failure. That is, if and when a "fail-safe" system fails, it remains at least as safe as it was before the failure. Since many types of failure are possible, failure mode and effects analysis is used to examine failure situations and recommend safety design and procedures. Some systems can never be made fail-safe, as continuous availability is needed. Redundancy, fault tolerance, or contingency plans are used for these situations (e.g. multiple independently controlled and fuel-fed engines). Examples Mechanical or physical Examples ...

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 ...

Hoofddorp Railway Station
Hoofddorp is a railway station in Hoofddorp, Netherlands located on the Weesp–Leiden railway. History From 1912 to 1935 the town had a station also called Hoofddorp nearer to the town centre at the ceased Hoofddorp–Leiden railway (''Haarlemmermeerspoorlijn'' from Aalsmeer to Haarlem, via Hoofddorp and Leiden). The former station building is in use as a residence. The current station opened on 31 May 1981. The station was rebuilt in 1998 to its current look. Hoofddorp has a depot/sidings further west from the station, this is the reason many sprinter services have their terminus over here. Intercity services terminating at Schiphol also use this depot before returning. The station consist of 2 double-track platforms and has 6 tracks. Regular bus services stop at street level below the station. ZuidTangent bus rapid transit lines 300 and 310 use the platform level stop next to the station. Train services , the following train services call at this station: *2× per hour loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vossloh G2000 BB
The G 2000 BB is a four axle heavy shunting and mainline locomotive, designed by German company Vossloh and built at the former MaK plant in Kiel. At the time of its introduction in 2000 it was the most powerful hydraulic transmission locomotive in Vossloh's range. History and design The locomotive was unveiled at Innotrans in 2000. The initial model had an asymmetric cab (see image) with a walkway; the asymmetric cab design allows the walkway to extend all the way to each end of the locomotive; coupled with remote control operation this means that shunting can be done from an external viewpoint whilst still riding on the locomotive. The design is modular with various components (engine, drive etc.) coming from different suppliers. External styling was by Tricon-Design. A second variant was produced, this time with a symmetrical cab; two different versions of this model were produced - one for the Italian market (G 2000-2 BB) with left hand drive (trains in Italy generally ...

Signal Passed At Danger
A signal passed at danger (SPAD), known in the United States as a stop signal overrun and in Canada as passing a stop signal, is an event on a railway where a train passes a stop signal without authority. In the United States and Canada, this may be known colloquially as '' running a red'', though this idiom principally refers to automobiles passing red traffic signals. The name derives from red colour light signals and horizontal semaphore signals in the United Kingdom, which are said to be ''at danger'' when they indicate that trains must stop (also known as the signal being ''on''). This terminology is not used in North America where not all red signals indicate stop. In the UK, the alternative description signal passed at red (S.P.A.R.) is used where a signal changes to red in front of a train due to either a technical fault or in an emergency, such that the train is unable to stop before passing the signal despite being driven correctly. Causes Because of its high inert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Yard
A rail yard, railway yard, railroad yard (US) or simply yard, is a series of tracks in a rail network for storing, sorting, or loading and unloading rail vehicles and locomotives. Yards have many tracks in parallel for keeping rolling stock or unused locomotives stored off the main line, so that they do not obstruct the flow of traffic. Cars or wagons are moved around by specially designed yard switchers (US) or shunters, a type of locomotive. Cars or wagons in a yard may be sorted by numerous categories, including railway company, loaded or unloaded, destination, car type, or whether they need repairs. Yards are normally built where there is a need to store rail vehicles while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations. Many yards are located at strategic points on a main line. Main-line yards are often composed of an up yard and a down yard, linked to the associated direction of trave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
