Balises
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 to radi ...

Eurobalise
A Eurobalise is a specific variant of a balise being a transponder placed between the rails of a railway. These balises constitute an integral part of the European Train Control System, where they serve as "beacons" giving the exact location of a train as well as transmitting signalling information in a digital telegram to the train. Overview A balise typically needs no power source. In response to radio frequency energy broadcast by a (BTM) mounted under a passing train, the balise transmits information to the train ('Uplink'). The provisions for Eurobalises to receive information from the train ('Downlink') has been removed from the specification. The transmission rate is sufficient to transmit at least 3 copies of a 'telegram' to be received by a train passing at any speed up to 500 km/h. Eurobalises are typically placed in pairs on two sleepers in the center of the track. For ETCS they are typically spaced 3 metres apart. With the balises being numbered the train will ...

European Train Control System
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] |

ZUB 121
The ZUB 1xx system is a family of train protection systems produced by Siemens. Its ZUB balises were deployed in the ZUB 121 train protection system in the Swiss railway network, in the ZUB 122 tilting control system in the German railway network, and in the ZUB 123 train protection system in the Danish railway network. Some of these were adapted for other railway lines before the next generation ZUB 2xx family was introduced which is based on Eurobalises - the earlier ZUB balises are not compatible with those. History The German LZB was created in 1965 and it was deployed on high-speed lines throughout the 1970s. However, with its signal wire along the complete length of a track it was considered too expensive in order to replace the traditional PZB inductive train stops that have been put along with line-side signals. In the 1980s the manufacturers of railway signaling systems developed electronic versions that could be deployed in the same pattern as the traditional train s ...

Geschwindigkeitsüberwachung Neigetechnik
The train protection system Geschwindigkeitsüberwachung Neigetechnik (German, translated "Speed Control for Tilting Technology) (abbr. GNT) enables to rise the speed of tilting trains until 30% above the limits for conventional trains. It is installed on numerous lines in Germany along with the traditional Punktförmige Zugbeeinflussung (PZB) intermittent signalling system. History Prior to GNT the tilting control was added as a subset of the Linienzugbeeinflussung (LZB) train protection system that has been in service on high-speed lines since the 1960s. It turned out that the switch from PZB to LZB on some regional lines was considered to be too expensive. As such Siemens was tasked to provide ZUB balises that would work on top of the existing line side signalling and their PZB controlled restrictions. It was developed and introduced under the title ''Punktförmiges Datenübertragungs-System'' (transl. "Punctiform Data Transfer System"). Because of conflicts of the abbreviat ...

Zugbeeinflussungssystem S-Bahn Berlin
The Berlin S-Bahn Train Control System - (ZBS) - is a train protection system based on Eurobalises that is designed for the specific requirements of the S-Bahn Berlin rapid transit rail network. It is able to gradually replace the old system based on train stops with overlap safety. The conversion will be finished on the subnetwork Stadtbahn until the end of 2020, on the subnetwork Nord-Süd until the end of 2023 and on the subnetwork Ring until the end of 2025. History The Berlin S-Bahn commuter rail system has its own tracks that is completely separate from the national rail network although most lines run in parallel with the normal railways. Although a heavy rail system the vehicle fleet is specialized for the Berlin rail network with its closest cousins in the S-Bahn Hamburg (which switched to 1200 Volt however instead of 750 Volt third rail in Berlin). Berlin was among the first to introduce an automated train protection system based on metal bar at the height of the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EBICAB
EBICAB is a trademark registered by Bombardier (later Alstom) for the equipment on board a train used as a part of an Automatic Train Control system. EBICAB 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 the other direction with semicontinuous speed supervision, using a wayside to train punctual transmission using wayside transponders. Versions EBICAB comes in two versions, EBICAB 700 in Sweden, Norway, Portugal and Bulgaria and EBICAB 900 installed in the spanish Mediterranean Corridor ( vmax= 220 km/h), and in Finland ( fi, Junakulunvalvonta) under the name ATP-VR/RHK.

Chinese Train Control System
The Chinese Train Control System (CTCS, ''simpl.chinese:'' 中国列车控制系统) is a train control system used on railway lines in People's Republic of China. CTCS is similar to the European Train Control System (ETCS). It has two subsystems: ground subsystem and onboard subsystem. The ground subsystem may based on balise, track circuit, radio communication network (GSM-R), and Radio Block Center (RBC). The onboard subsystem includes onboard computer and communication module. CTCS Levels There consists of 5 different levels (Level 0 to Level 5). Levels 2, 3, and 4 are back-compatible with lower levels. CTCS Level 0 (CTCS-0) For railway lines where operational speeds are below : * Track configuration: Track circuit * Cab configuration: CTCS Universal Cab Signalling (UCS) + Train operating service unit (TOSU/LKJ) + Driver Machine Interface (DMI). Level 0 is used on lines with conventional trackside signalling. Train drivers follow trackside signals primarily, with cab sig ...

Wrong-side Failure
A wrong-side failure describes a failure condition in a piece of railway signalling equipment that results in an unsafe state. A typical example would be a signal showing a 'proceed' aspect (e.g. green) when it should be showing a 'stop' or 'danger' aspect, resulting in a "false clear". (The converse is a right-side failure, where even with any reduction the resulting state is safe overall.) Example of how a wrong-side failure may occur Consider a relay that has to energize to show a green light. If a wire breaks, or the battery is drained, then the relay will de-energize and the signal will show a red light, which is fail-safe. If a stray wire from another circuit touches the wire connected to that same relay, then that would be a wrong side failure, which is potentially dangerous. This stray wire can be guarded against by ensuring that the insulation on the relay wire is of good quality, and that all terminals are locked away. In addition, the relay may be double-switched ...
