Railway signalling (BE), or railroad signaling (AE), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year.
The Train Protection & Warning System (TPWS) is a train protection system used throughout the British passenger main-line railway network, and in Victoria, Australia.
Rail transport in Australia is a component of the Australian transport system. It is to a large extent state-based, as each state largely has its own operations, with the interstate network being developed ever since Australia's federation in 1901. As of 2022, the Australian rail network consists of a total of 32,929 kilometres (20,461 mi) of track built to three major track gauges: 18,007 kilometres (11,189 mi) of standard gauge, 2,685 kilometres (1,668 mi) of broad gauge, and 11,914 kilometres (7,403 mi) of narrow gauge lines. Additionally, about 1,400 kilometres (870 mi) of 610 mm / 2 ft gauge lines support the sugar-cane industry. 3,488 kilometres (2,167 mi), around 11 percent of the Australian heavy railways network route-kilometres are electrified.
Automatic Warning System (AWS) is a railway safety system invented and predominantly used in the United Kingdom. It provides a train driver with an audible indication of whether the next signal they are approaching is clear or at caution. Depending on the upcoming signal state, the AWS will either produce a 'horn' sound, or a 'bell' sound. If the train driver fails to acknowledge a warning indication, an emergency brake application is initiated by the AWS. However if the driver correctly acknowledges the warning indication by pressing an acknowledgement button, then a visual 'sunflower' is displayed to the driver, as a reminder of the warning.
Cab signaling is a railway safety system that communicates track status and condition information to the cab, crew compartment or driver's compartment of a locomotive, railcar or multiple unit. The information is continually updated giving an easy to read display to the train driver or engine driver.
The Australian Rail Track Corporation (ARTC) is an Australian Government-owned statutory corporation. It operates one of the largest rail networks in the nation, spanning 8,500 km across five states and 39 worksites.
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).
Linienzugbeeinflussung is a cab signalling and train protection system used on selected German and Austrian railway lines as well as on the AVE and some commuter rail lines in Spain. The system was mandatory where trains were allowed to exceed speeds of 160 km/h (99 mph) in Germany and 220 km/h (140 mph) in Spain. It is also used on some slower railway and urban rapid transit lines to increase capacity. The German Linienzugbeeinflussung translates to continuous train control, literally: linear train influencing. It is also called linienförmige 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 UK, and formerly on the Trillium Line in Canada.
The Dry Creek–Port Adelaide railway line is an eight-kilometre east–west freight railway line running through Adelaide's north-western suburbs. The line is managed by the Australian Rail Track Corporation (ARTC) and is an important link between Port Adelaide, Pelican Point and the main interstate rail routes which link Adelaide with Melbourne, Perth, Darwin and Sydney. Prior to 1988, a limited local passenger service operated, stopping at five intermediate stations along the line. Since May 1988, the line has been freight-only.
Australian railway signalling varies between the States of Australia, because the individual States are responsible for the railway systems within their own borders, with, historically, no need to co-ordinate between states except at the boundaries.
A train protection system is a railway technical installation to ensure safe operation in the event of human error.
An axle counter is a system used in railway signalling to detect the clear or occupied status of a section of track between two points. The system generally consists of a wheel sensor and an evaluation unit for counting the axles of the train both into and out of the section. They are often used to replace a track circuit.
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
The Adelaide–Port Augusta railway line is the main route for northbound rail traffic out of Adelaide, South Australia. The line, 315 kilometres long, is part of the Adelaide–Darwin rail corridor and the Sydney–Perth rail corridor.
The Chinese Train Control System 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).
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This can make railway traffic management safer and more efficient. Rapid transit systems are able to reduce headways while maintaining or even improving safety.
Anuncio de Señales y Frenado Automático is an Automatic Train Protection system widely deployed on the Spanish rail network. It consists of a mechanism that stops a train if the driver does not properly heed signals.
Route knowledge is one of the core skills together with train handling and a full understanding of railway rules, which the operating crew must possess in order to be able to operate a train safely.
KAVACH is an 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.
