European Train Control System
The European Train Control System (ETCS) is a train protection system designed to replace the many incompatible systems used by European railways, and railways outside of Europe. ETCS is the signalling and control component of the European Rail Traffic Management System (ERTMS). ETCS consists of 2 major parts: #trackside equipment #on-board (on train) equipment ETCS can allow all trackside information to be passed to the driver cab, removing the need for trackside signals. This is the foundation for future automatic train operation (ATO). 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 intermittent according to the ERTMS/ETCS level of application and to the nature of the information itself. The need for a system like ETCS stems from more and longer running trains resulting from economic integration of the European Union (EU) and the ...

Baseline (configuration Management)
In configuration management, a baseline is an agreed description of the attributes of a product, at a point in time, which serves as a basis for defining change. A change is a movement from this baseline state to a next state. The identification of significant changes from the baseline state is the central purpose of baseline identification.CMMI Product Team, "Chpt 7, Maturity Level 2: Managed, Configuration Management, SP 1.3," in ''Capability Maturity Model Integration, Version 1.1 (CMMI-SE/SW/IPPD/SS, V1.1): Staged Representation,'' Carnegie Mellon Software Engineering Institute. Typically, significant states are those that receive a formal approval status, either explicitly or implicitly. An approval status may be attributed to individual items, when a prior definition for that status has been established by project leaders, or signified by mere association to a particular established baseline. Nevertheless, this approval status is usually recognized publicly. A baseline may b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Bahn
(, ; abbreviated as DB or DB AG ) is the national railway company of Germany, and a state-owned enterprise under the control of the German government.

GSM-R
GSM-R, Global System for Mobile Communications – Railway or GSM-Railway is an international wireless communications standard for railway communication and applications. A sub-system of European Rail Traffic Management System (ERTMS), it is used for communication between train and railway regulation control centers. The system is based on GSM and ''EIRENE – MORANE'' specifications which guarantee performance at speeds up to 500 km/h (310 mph), without any communication loss. GSM-R could be supplanted by LTE-R, with the first production implementation being in South Korea. However, LTE (telecommunication), LTE is generally considered to be a "4G" protocol, and the International Union of Railways, UIC's Future Railway Mobile Communication System (FRMCS) program is considering moving to something "5G"-based (specifically 3GPP R15/16, i.e. 5G NR), thus skipping two technological generations. History GSM-R is built on GSM technology, and benefits from the economie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integra-Signum
Integra-Signum is a Swiss train protection system introduced in 1933. Originally it was called Signum; the name Integra was added later. It transmits data inductively and is simple, robust and reliable also in snow. How it works The locomotives have three sending and receiving magnets and there are two trackside magnets near the signals. Integra-Signum requires the train driver to confirm distant signals that show stop and distant or home signals that show caution. If no confirmation is received or a home signal that shows stop is passed without authority, the train is stopped automatically. This is achieved by interrupting the power supply to the motors and applying the emergency brake. The locomotive's sending magnet is a strong permanent magnet, which induces a current in the receiving magnet in the middle of the track, if the signal's short-circuit contact is closed. The receiving magnet on the locomotive consists of two magnet field detectors, which detect the signal's sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sistema Controllo Marcia Treno
Sistema di Controllo della Marcia del Treno (SCMT) is a discontinuous train cab signalling system used in Italy. It shares many features with the Ripetizione Segnali (RS) system, the two systems co-existing and working together. The main purpose of SCMT is to control the respect of the speed limit imposed by the signal aspect and the line condition. SCMT is divided in two parts: *SSB: ''Sottosistema di bordo'' ("Onboard Subsystem") *SST: ''Sottosistema di terra'' ("Ground Subsystem") Working principles SCMT is based upon an array of transponders called "Punto informativo" (PI) placed on the tracks near signals, reduced speed zones, and other important points along the line. The PIs form the SST. When a train passes over a PI, a set of "antennas" mounted in front of the first bogie energize it through induction. The PI then passes information about the aspect of the next signal through the antennas to the SSB. If the system is supported by RS, and if the signal shows a ...

Eurobalise
A Eurobalise is a specific type of a balise installed between the rails of a railway. Eurobalises are part of the European Train Control System (ETCS). The balises are pre-programmed and contain information that is read by train antennas. One of their many functions is to allow a train to determine its location. Overview A balise typically needs no wayside power source. Coupling between the balise and the vehicle-mounted antenna is by magnetic induction, similar to a transformer - although operating at frequencies typical of radio, it is not a radio system. In response to "telepowering" by means of a 27 MHz, CW-modulated magnetic field transmitted by a (BTM and its associated antenna) mounted under a passing train, the balise transmits information to the train (''uplink'') by means of a 4.234 MHz FSK-modulated magnetic field. The original provisions for Eurobalises to receive information from the train (''downlink'') have been removed from the specification. The tra ...

European Commission
The European Commission (EC) is the primary Executive (government), executive arm of the European Union (EU). It operates as a cabinet government, with a number of European Commissioner, members of the Commission (directorial system, informally known as "commissioners") corresponding to two thirds of the number of Member state of the European Union, member states, unless the European Council, acting unanimously, decides to alter this number. The current number of commissioners is 27, including the president. It includes an administrative body of about 32,000 European civil servants. The commission is divided into departments known as Directorate-General, Directorates-General (DGs) that can be likened to departments or Ministry (government department), ministries each headed by a director-general who is responsible to a commissioner. Currently, there is one member per European Union member state, member state, but members are bound by their oath of office to represent the genera ...

European Railway Agency
The European Union Agency for Railways (ERA) is an agency of the European Union (EU) that sets mandatory requirements for European railways and manufacturers in the form of Technical Specifications for Interoperability (TSI), which apply to the Trans-European Rail system. The ERA publishes a document summarising the status of the TSIs. The ERA sets common safety targets, common safety methods and common safety indicators, following Directive 2004/49/EC and amendments. The ERA also hosts a number of databases, among which a register of remaining, applicable national rules. One of its primary duties is the development and implementation of the European Rail Traffic Management System (ERTMS). History Prior to the establishment of the agency, the railway networks of each individual member state within the European Union had been unique and typically employing high levels of bespoke, self-developed working practices, rolling stock, and infrastructure; the requirements pertaining to s ...

Invensys
Invensys Limited was a multinational engineering and information technology company headquartered in London, United Kingdom. At its height, the company had offices in more than 50 countries and its products were sold in around 180 countries. Invensys was formed in 1999 through the merger of BTR plc and Siebe plc. It was originally founded on 1 April 1920 as ''Siebe Gorman & Company Ltd'' and continued through various name changes registered at Companies House from that date.
