{{Short description|Automatic train control systems}}
'''EBICab''' is a trademark registered by [[Alstom]] (former [[Bombardier_Transportation|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 [[Punktförmige_Zugbeeinflussung|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 [[Punktförmige_Zugbeeinflussung|PZB]] and [[Linienzugbeeinflussung|LZB]] as a combined [[European_Train_Control_System#Specific_Transmission_Modules|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]]).<ref>{{Cite web|url=https://www.sjt.no/globalassets/02_jernbane/pdf-jernbane/regelverk/stm/vagledning-atc-installationer_i_fordon-v01.pdf|title=ATC-installationer i fordon|last=Sollander|first=Stefan|date=2008-04-18|website=[[Swedish Transport Agency]]|language=sv|type=PDF; 150 kB|access-date=2018-09-10}}</ref> ATC-2 was also developed in Sweden.<ref>[http://www.teknogram.se/links/lawson/lawson.html Teknogram Twenty Years of Safe Train Control in Sweden] {{webarchive|url=https://web.archive.org/web/20100826134339/http://www.teknogram.se/links/lawson/lawson.html |date=2010-08-26 }}</ref>

[[Image:EBICAB.jpg|thumb|230px|EBICab balise in the Mediterranean Corridor]]
These on-board systems use pairs of [[balise]]s 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 [[transponder]]s.<ref>[http://www.jernbaneverket.no/Documents/Marked/Infrastrukturens%20egenskaper/590/T90-0502.pdf Jernbaneverket / INFRASTRUKTURENS EGENSKAPER, 2001-02-05]{{Dead link|date=July 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

=== Versions ===
EBICab comes in two versions, EBICab 700 in [[Sweden]], [[Norway]], [[Portugal]] and [[Bulgaria]] and EBICab 900 installed in the spanish Mediterranean Corridor ([[Velocity|v<sub>max</sub>]]= 220 km/h), and in [[Finland]] ({{langx|fi|Junakulunvalvonta}}) under the name '''ATP-VR/RHK'''. In [[Portugal]] it is known as '''Convel''' (the contraction of Controlo de Velocidade, meaning Speed Control).

The EBICab 900 system uses wayside balises with signal encoders or series communications with electronic [[lookup table]], and on-board equipment on the train. The transmission of data occurs between the passive wayside balises (between 2 and 4 per signal) and the antenna installed under the train, which powers the balises when it passes over the balises. The coupling between the balise and the on-board antenna is inductive.

In comparison with [[Anuncio de Señales y Frenado Automático|ASFA]], a system which transmits only a maximum amount of data per frequency, EBICAB uses electronic lookup table, the amount of data transmitted is much larger.

[[Adif]]/[[Renfe]], in [[Spain]], sometimes use the term [[Automatic Train Protection|ATP]] to refer to EBICAB 900, which is the first system on its network to provide Automatic Train Protection. The [[Manila MRT Line 3]] in the [[Philippines]] also uses the ATP term to refer to EBICAB 900.<ref>{{Cite report |author=Department of Transportation and Communications |date=March 2013 |title=MRT3 System Temporary Maintenance Provider – One (1) Year |url=https://dotr.gov.ph/images/Public_Bidding/Goods/2013/Rail/MRT3SystemMaintenanceProvider/final%20pbd_mrt3%20maintenance%20prov.pdf |access-date=2 March 2022 |archive-date=27 December 2021 |archive-url=https://web.archive.org/web/20211227211550/https://dotr.gov.ph/images/Public_Bidding/Goods/2013/Rail/MRT3SystemMaintenanceProvider/final%20pbd_mrt3%20maintenance%20prov.pdf |url-status=dead }}</ref>

=== Main Characteristics ===

* Transponders operating in the ISM band at 27 MHz amplitude modulated for the clock pulses and impulse frequency of 50 kHz.
* Transmission of data to trains at 4,5 MHz at 50 kbit/s with 32 bit packets encoding 12 bits of information (EBICAB 700) or 255 bit packets encoding 180 bits of information (EBICab 900), including the necessary synchronisation bits.
* The signals are linked (concatenated), but the signs, for example, for warnings and speed, are not necessarily linked (concatenated); it is acceptable to have 50% of the transponders linked to be safe against failures.
* The driver may input characteristics such as train identification, length, speed type, maximum speed, braking characteristics, and train pressure.
* The driver receives visual indications such as speed limit, target speed, overspeed, ASFA Alarm, braking reset, Permission to Pass, alarm signals, braking warning, red or alphanumeric indications.

=== Supervision ===

* Line velocity, as a function of line capacity and the vehicle's performance capabilities in situations of overspeed or the imposition of lower velocity for some types of trains.
* Multiple objectives, including signaling information without wayside signals.
* The system can enforce permanent, temporary and emergency speed restrictions by using unlinked (concatenated) transponders.
* Stop Point.
* Dynamic braking profile.
* Status of the level crossing and landslide detectors.
* Maneuvers.
* Protection against wheel wear.
* Slip/Slide compensation.
* Authorization to pass a signal at Stop.

=== Warnings ===

* Acoustic warning at excess of 5 km/h, service braking at excess of 10 km/h and emergency brake application at excess of 15 km/h
* The operator may release service braking when the speed is below one of the speed limits (Normally below the speed limit + 10 km/h in Portugal).

=== Differences ===

The most important difference with EBICab 900, is that EBICab 700 can only transmit packets with 12 useful bits for a total of 32bits and allows up to 5 transponders per signal.

== EBICab 2000 ==
The EBICab 2000 is Bombardier's implementation of a [[European_Train_Control_System|ETCS]], operated in several European countries (Germany, [[Switzerland]], [[United Kingdom]], [[Belgium]], [[Netherlands]], [[Spain]], [[Sweden]], [[Poland]]). It can read [[Eurobalise|Eurobalises]] and can communicate by [[European_Train_Control_System#Euroradio|Euroradio]] with a [[European Train Control System#Radio Block Centre|RBC]].
