LOCOPROL
LOCOPROL (Low Cost satellite based train location system for signalling and train Protection for Low density traffic railway lines) has been a project to research the integration of satellite navigation into railway networks targeting low-density track lines. It is supposed to extend the ERTMS train protection systems. The partner project LOCOLOC was looking into cab signaling and speed control measures. Locoprol has its technical foundation in systems like Euteltrac / OmniTRACS from Qualcomm in use since 1991 for satellite-based fleet managementacroread followed by APOLO (Advanced Position Locator), ECORAIL (EGNOS Controlled Railway Equipment) and the parallel INTEGRAIL project (2001–2003) der ESA The LOCOPROL project was funded by the 5. Framework Programme of the EU just like the GADEROS project (GAlileo DEmonstrator Railway Operation System) starting at the same to research the integration of satellite navigation into the ERTMS standard (project partners were INECO, TIFSA ...

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. A simplistic form of train traffic governance is ''negative'' train control, where trains must stop when issued a stop order and can move in the absence of such. An example of negative train control is Indusi. In contrast, ''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. As of 2019, the U.S. freight rail industry trade organization AAR claimed that the nation's largest freight railroads were operating PTC across 83.2 percent of the required route miles.

ERTMS
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 ...

GADEROS
GADEROS (Galileo Demonstrator for Railway Operation System) is a study sponsored by the European Commission. The purpose is to make use of the Galileo Global Navigation Satellite System (GNSS) when it becomes functional in 2008. Current terrestrial railroad tracking systems require huge distances as safety margins. This leads to lower freight and passenger throughput.

Dead Reckoning
In navigation, dead reckoning is the process of calculating current position of some moving object by using a previously determined position, or fix, and then incorporating estimates of speed, heading direction, and course over elapsed time. The corresponding term in biology, used to describe the processes by which animals update their estimates of position or heading, is path integration. Dead reckoning is subject to cumulative errors. Advances in navigational aids that give accurate information on position, in particular satellite navigation using the Global Positioning System, have made simple dead reckoning by humans obsolete for most purposes. However, inertial navigation systems, which provide very accurate directional information, use dead reckoning and are very widely applied. Etymology The term "dead reckoning" was not originally used to abbreviate "deduced reckoning," nor is it a misspelling of the term "ded reckoning." The use of "ded" or "deduced reckoning" ...

Inertial Navigation System
An inertial navigation system (INS) is a navigation device that uses motion sensors (accelerometers), rotation sensors ( gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors ( magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Other terms used to refer to inertial navigation systems or closely related devices include inertial guidance system, inertial instrument, inertial measurement unit (IMU) and many other variations. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Overview Inertial navigation is a self-c ...

Safety Integrity Level
Safety integrity level (SIL) is defined as the relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a safety instrumented function (SIF). The requirements for a given SIL are not consistent among all of the functional safety standards. In the functional safety standards based on the IEC 61508 standard, four SILs are defined, with SIL 4 the most dependable and SIL 1 the least. The applicable SIL is determined based on a number of quantitative factors in combination with qualitative factors such as development process and safety life cycle management. Assignment Assignment of SIL is an exercise in risk analysis where the risk associated with a specific hazard, that is intended to be protected against by a SIF, is calculated without the beneficial risk reduction effect of the SIF. That unmitigated risk is then compared against a tolerable risk target. The d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EGNOS
The European Geostationary Navigation Overlay Service (EGNOS) is a satellite-based augmentation system (SBAS) developed by the European Space Agency and EUROCONTROL on behalf of the European Commission. Currently, it supplements the GPS by reporting on the reliability and accuracy of their positioning data and sending out corrections. The system will supplement Galileo in a future version. EGNOS consists of 40 Ranging Integrity Monitoring Stations, 2 Mission Control Centres, 6 Navigation Land Earth Stations, the EGNOS Wide Area Network (EWAN), and 3 geostationary satellites. Ground stations determine accuracy data of the satellite navigation systems and transfer it to the geostationary satellites; users may freely obtain this data from those satellites using an EGNOS-enabled receiver, or over the Internet. One main use of the system is in aviation. According to specifications, horizontal position accuracy when using EGNOS-provided corrections should be better than seven metre ...

ERTMS Regional
ERTMS Regional is a simplified and low-cost variant of the European Rail Traffic Management System suitable for train control on lines with low traffic volumes. It is intended to reduce the amount of lineside and equipment required, thus reducing costs, increasing reliability and improving safety for track workers. History The ERTMS Regional project was started at the end of the 1990s under the name ETCS LC (Low Cost). In recent years, its development was pushed by the Swedish Rail Administration in cooperation with the UIC organization. Standardization reached a point in 2009 that the Swedish Rail Administration ordered the equipping of a pilot railway track on the 129-kilometer West Dalarna Line between Malung and Repbäcken in Sweden. Test operation started in 2010, and it has been fully operational (ERTMS only) since February 2012. Unfortunately the high cost of equipping passenger trains with ERTMS caused cancellation of all passenger traffic on this line in 2011. There ...

Train Protection System
A train protection system is a railway technical installation to ensure safe operation in the event of human error. Development Train stops The earliest systems were train stops, as still used by the New York City Subway, the Toronto subway, the London Underground, the Moscow Subway (only on the older lines) and the Berlin S-Bahn. Beside every signal is a moveable arm. If the signal is red, levers connected to valves on any passing train hit the arm, opening the brake line, applying the emergency brake, If the signal shows green, the arm is turned away from the levers and there is no contact. The Great Western Railway in the UK introduced its ' automatic train control' system in the early years of the 20th century. Each distant signal had before it a ramp between the running rails. If the signal showed green, the ramp was energised with a low voltage current which was passed to the locomotive when a shoe came into contact with the ramp. A bell rang in the locomotive's ca ...
