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 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 ...

Balise
A balise ( ) is an electronic beacon or transponder placed between the rails of a railway as part of an automatic train protection (ATP) system. The French word '' balise'' is used to distinguish these beacons from other kinds of beacons. Balises are used in the KVB signalling system installed on main lines of the French railway network, other than the high-speed Lignes à Grande Vitesse. Balises constitute an integral part of the European Train Control System, where they serve as "beacons" giving the exact location of a train. The ETCS signalling system is gradually being introduced on railways throughout the European Union. Balises are also used in the Chinese Train Control System versions CTCS-2 and CTCS-3 installed on high-speed rail lines in China, which is based on the European Train Control System. A balise which complies with the European Train Control System specification is called a Eurobalise. Overview A balise typically needs no power source. In response t ...

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] |
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 ad ...

Citizens Band Radio
Citizens band radio (CB radio) is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or shortwave band. Citizens band is distinct from other personal radio service allocations such as FRS, GMRS, MURS, UHF CB and the Amateur Radio Service ( "ham" radio). In many countries, CB operation does not require a license and may be used for business or personal communications. Like many other land mobile radio services, multiple radios in a local area share a single frequency channel, but only one can transmit at a time. The radio is normally in receive mode to receive transmissions of other radios on the channel; when users want to communicate they press a "push to talk" button on their radio, which turns on their transmitter. Users on a channel must take turns transmitting. In the US and Canada, and in the EU and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
