Train Speed Optimization
{{Unsourced, date=November 2019 Train speed optimization, also known as Zuglaufoptimierung, is a system that reduces the need for trains to brake and accelerate, resulting in smoother and more efficient operation. While train speed optimization needs some technical infrastructure, it is more of an operational concept than a technical installation. One can relatively easily implement train speed optimization using for instance cab signalling (e.g. using ETCS), but the presence of a cab signalling system does not necessarily mean that it uses train speed optimization. Train speed optimization may also be implemented using conventional Railway signalling, signalling. Conventional signal operation Usually, trains are allowed to run at the maximum speed the track allows until the distant Railway signal, signal of next occupied block. This is inefficient in many cases, because this way the train comes to a halt in front of the red signal and has to accelerate again from zero. Advantage ...

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 ...

Cab Signalling
Cab signaling is a railway safety system that communicates track status and condition information to the cab, crew compartment or driver's compartment of a locomotive, railcar or multiple unit. The information is continually updated giving an easy to read display to the train driver or engine driver. The simplest systems display the trackside signal, while more sophisticated systems also display allowable speed, location of nearby trains, and dynamic information about the track ahead. Cab signals can also be part of a more comprehensive train protection system that can automatically apply the brakes stopping the train if the operator does not respond appropriately to a dangerous condition. Overview The main purpose of a signal system is to enforce a safe separation between trains and to stop or slow trains in advance of a restrictive situation. The cab signal system is an improvement over the wayside signal system, where visual signals beside or above the right-of-way gov ...

ETCS
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] |
Railway Signalling
Railway signalling (), also called railroad signaling (), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year. Most forms of train control involve movement authority being passed from those responsible for each section of a rail network (e.g. a signalman or stationmaster) to the train crew. The set of rules and the physical equipment used to accomplish this determine what is known as the ''method of working'' (UK), ''method of operation'' (US) or ''safeworking'' (Aus.). Not all these methods require the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Signal
A railway signal is a visual display device that conveys instructions or provides warning of instructions regarding the driver’s authority to proceed. The driver interprets the signal's indication and acts accordingly. Typically, a signal might inform the driver of the speed at which the train may safely proceed or it may instruct the driver to stop. Application and positioning of signals Originally, signals displayed simple stop or proceed indications. As traffic density increased, this proved to be too limiting and refinements were added. One such refinement was the addition of distant signals on the approach to stop signals. The distant signal gave the driver warning that they were approaching a signal which might require a stop. This allowed for an overall increase in speed, since train drivers no longer had to drive at a speed within sighting distance of the stop signal. Under timetable and train order operation, the signals did not directly convey orders to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Protection System
A train protection system is a railway technical installation to ensure safe operation in the event of human error. Development Train stops The earliest systems were train stops, as still used by the New York City Subway, the Toronto subway, the London Underground, the Moscow Subway (only on the older lines) and the Berlin S-Bahn. Beside every signal is a moveable arm. If the signal is red, levers connected to valves on any passing train hit the arm, opening the brake line, applying the emergency brake, If the signal shows green, the arm is turned away from the levers and there is no contact. The Great Western Railway in the UK introduced its 'automatic train control' system in the early years of the 20th century. Each distant signal had before it a ramp between the running rails. If the signal showed green, the ramp was energised with a low voltage current which was passed to the locomotive when a shoe came into contact with the ramp. A bell rang in the locomotive's cab t ...

Inductive Loop
An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence indicators. A common modern use for induction loops is to provide hearing assistance to hearing-aid users. Applications Vehicle detection Vehicle detection loops, called ''inductive-loop traffic detectors'', can detect vehicles passing or arriving at a certain point, for instance approaching a traffic light or in motorway traffic. An insulated, electrically conducting loop is installed in the pavement. The electronics unit applies alternating current electrical energy onto the wire loops at frequencies between 10 k Hz to 200 kHz, depending on the model. The inductive-loop system behaves as a tuned electrical circuit in which the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swiss Federal Railways
Swiss Federal Railways (german: link=no, Schweizerische Bundesbahnen, ''SBB''; french: link=no, Chemins de fer fédéraux suisses, ''CFF''; it, Ferrovie federali svizzere, ''FFS'') is the national railway company of Switzerland. It is usually referred to by the initials of its German, French, and Italian names, either as SBB CFF FFS, or used separately. The Romansh version of its name, ''Viafiers federalas svizras'', is not officially used. The official English abbreviation is "SBB", instead of the English acronym such as "SFR", which stands for ''Swiss Federal Railways'' itself. The company, founded in 1902, is headquartered in Bern. It used to be a government institution, but since 1999 it has been a special stock corporation whose shares are held by the Swiss Confederation and the Swiss cantons. It is currently the largest rail and transport company of Switzerland, and operates on most standard gauge lines of the Swiss network. It also heavily collaborates with ...

Lenzburg
Lenzburg is a town in the central region of the Swiss canton Aargau and is the capital of the Lenzburg District. The town, founded in the Middle Ages, lies in the Seetal valley, about 3 kilometres south of the Aare river. Lenzburg and the neighbouring municipalities of Niederlenz and Staufen have grown together in an agglomeration. History A Neolithic grave field of the Cortaillod culture has been discovered on the ''Goffersberg'' (close to the Lenzburg Castle) dating from 4300 - 3500 BCE. A Roman theater was uncovered when a motorway was built in 1964. It was part of a small settlement with 500 inhabitants that existed for approximately 200 years. The settlement was abandoned in the 3rd century. In the 5th and 6th centuries, an Alamanni settlement existed. Lenzburg is first mentioned in 924 as ''de Lencis''. In 1036, Lenzburg Castle was used for the first time as seat for the Count of Lenzburg, then an important lord. The house however died out in 1173, and the castle was t ...

Killwangen
Killwangen is a municipality in the district of Baden in the canton of Aargau in Switzerland ). Swiss law does not designate a ''capital'' as such, but the federal parliament and government are installed in Bern, while other federal institutions, such as the federal courts, are in other cities (Bellinzona, Lausanne, Luzern, Neuchâtel .... History The town was first known as ''Chullewangen'' as early as 1227. The name is alemannish in origin. For nearly 600 years, Killwangen was dependent on the monastery in nearby Wettingen. In 1798, Napoleon's troops came through Switzerland and the Helvetic Republic was born. Killwangen was part of the Canton of Baden which enjoyed a short history as a separate Canton, being absorbed by the new Canton of Aargau in 1803. On 7 August 1847, the first railway line in Switzerland opened between Baden and Zurich. On 1 February 1848, the town received its own railways station on the pioneer line.

Altstetten (Zürich)
Altstetten is a quarter in district 9 of the city of Zürich in Switzerland. It was formerly a municipality in its own right, but was incorporated into Zürich in 1934. History Altstetten is first mentioned in 1249, at which time a distinction was made between ''in Altstettin superiori'' and ''in villa Altstetin Inferiori''. Excavations have found remains probably from the late Bronze Age (1000-800 BC), together with those of a Roman villa. In 1847, the Swiss Northern Railway opened Switzerland's first domestic railway line between Zürich and Baden. The line passed through Altstetten, and a station was provided. Over time, the line became the principal rail route between Zürich and northern and western Switzerland. In 1864, a second line, to Zug via Affoltern am Albis, made a junction with the first just west of Altstetten railway station. In 1907, the Swiss Federal Railway, who had taken over both lines, opened a workshop in Altstetten. In 1900, the Limmattal-Strassenbahn op ...
