Automatic Train Protection
Automatic train protection (ATP) is the generic term for train protection systems that continually check that the speed of a train is compatible with the permitted speed allowed by signalling, including automatic stop at certain signal aspects. If it is not, ATP activates an Emergency brake (train), emergency brake to stop the train.

EBICAB
EBICab is a trademark registered by Alstom (former Bombardier) for the equipment on board a train used as a part of an Automatic Train Control system. Three different families exist, which are technically unrelated. EBICab 500/600 EBICab 500 is Bombardier's implementation of the German PZB, the train protection system widely used in Germany, Austria and other countries, allowing operation up to 160 km/h. EBICab 600 is Bombardier's implementation of the German PZB and LZB as a combined STM. The LZB is used on high-speed tracks in Germany, up to 300 km/h. EBICab 700/900 EBICab 700 was originally derived from Ericsson's SLR system in Sweden. Most trains in Sweden and Norway use a similar on-board system, Ansaldo L10000 (more known as ATC-2) from Bombardier's competitor Ansaldo STS (now Hitachi Rail STS). ATC-2 was also developed in Sweden. These on-board systems use pairs of balises mounted on the sleepers. The pairs of balises distinguish signals in one direction from t ...

Train Protection & Warning System
The Train Protection & Warning System (TPWS) is a train protection system used throughout the British passenger main-line railway network, and in Victoria, Australia. According to the UK Rail Safety and Standards Board, the purpose of TPWS is to stop a train by automatically initiating a brake demand, where TPWS track equipment is fitted, if the train has: passed a signal at danger without authority; approached a signal at danger too fast; approached a reduction in permissible speed too fast; approached buffer stops too fast. TPWS is not designed to prevent signals passed at danger (SPADs) but to mitigate the consequences of a SPAD, by preventing a train that has had a SPAD from reaching a conflict point after the signal. A standard installation consists of an on-track transmitter adjacent to a signal, activated when the signal is at danger. A train that passes the signal will have its emergency brake activated. If the train is travelling at speed, this may be too late to stop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, UK, and formerly on the Line 2 (O-Train), 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 a traditional a ...

Positive Train Control
Positive train control (PTC) is a family of automatic train protection systems deployed in the United States. Most of the United States' national rail network mileage has a form of PTC. These systems are generally designed to check that trains are moving safely and to stop them when they are not. Positive train control restricts the train movement to an explicit allowance; movement is halted upon invalidation. A train operating under PTC receives a ''movement authority'' containing information about its location and where it is allowed to safely travel. PTC was installed and operational on 100% of the statutory-required trackage by December 29, 2020. Overview The American Railway Engineering and Maintenance-of-Way Association (AREMA) describes positive train control systems as having these primary functions: * Train separation or collision avoidance * Line speed enforcement * Temporary speed restriction enforcement * Rail worker wayside safety * Blind spot monitoring History ...

Kavach - Indian Railways
KAVACH () is an Indian Automatic Train Protection (ATP) system indigenously developed by Research Designs & Standards Organisation (RDSO) in collaboration with ''Medha Servo Drives, Kernex Microsystems'' and ''HBL Power Systems''. Initially it was known by the name Train Collision Avoidance System (TCAS). Kavach was adopted by Ministry of Railways as the ''National ATP System'' in July 2020. Development of Kavach began in the year 2011 as an open architecture system. In 2014, field trials commenced. First field trial experiments on passenger trains was done in February 2016. Subsequently, Kavach received Safety Integrity Level (SIL-4) certification in the year 2019. It is being promoted as one of the cheapest ATP systems available worldwide. The Union budget of India for the FY 2022-23 allocated funds for the rapid implementation of Kavach across 2,000 km of track, as well as sanctioning its implementation along 34,000 km track of the Golden Quadrilateral rail route, which i ...

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 ...

Continuous Automatic Warning System
The Continuous Automatic Warning System (CAWS) is a form of cab signalling and train protection system used in Ireland to help train drivers observe and obey lineside signals. CAWS has been in use on Iarnród Éireann diesel trains since 1984. All NIR trains operating cross-border must also be fitted with CAWS. Coded track circuits, which form the basis of the system (see below), are installed on all Dublin Suburban and Intercity routes to Cork, Limerick, and Athlone and as far as the border on the Belfast line. This system is of American origin, being originally supplied by US&S, then a division of Westinghouse Air Brake Company (WABCO). Current equipment is supplied by SASIB, a division of Alstom. Principles of operation CAWS repeats the aspects shown by the lineside colour light signals on an aspect display unit (ADU) inside the driver's cab. The ADU continuously displays the aspect that was shown by the previous signal until updated about 350 metres before the next ...

Automatic Train Protection (United Kingdom)
Automatic Train Protection (ATP) is a method of beacon based railway cab signalling developed by British Rail. The system is only installed on the Great Western Main Line between London Paddington and Bristol Temple Meads, and the Chiltern Main Line from London Marylebone to High Wycombe and Aylesbury. History Background A noticeable uptick in signal passed at danger (SPAD) instances in the 1980s led to calls for a new safety system to be adopted that would entirely prevent their occurrence; specifically, the report into the Clapham Junction rail crash (itself not a SPAD accident) specifically stipulated that British Rail (BR) was to fully implement such a system on nationwide basis within five years. From the onset, it was recognised that considerable work would be involved both to develop and deploy the envisioned system. Accordingly, in 1988, BR launched a three-year program to develop and deploy this new system, with the aim of starting its implementation b ...

Automatische Treinbeïnvloeding
Automatische TreinBeïnvloeding or ATB ('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, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
