[1] [2] Initially it was known by the name Train Collision Avoidance System (TCAS). [3] [4] Kavach was adopted by Ministry of Railways as the National ATP System in July 2020. [5] Kavach functioning explained through schematic diagram. Development of Kavach began in the year 2011 as an open architecture system. In 2014, field trials commenced.
The on-board train protection device, the first device designed by Konkan Railway with their technical partner Kernex Microsystems (I) Ltd, was installed throughout the Indian Railway network. A new ACD Version-II, now called the Train Collision Avoidance System (TCAS), is under development by The Research Designs and Standards Organisation (RDSO).
A simple collision avoidance system. In transportation, collision avoidance is the maintenance of systems and practices designed to prevent vehicles (such as aircraft, motor vehicles, ships, cranes and trains) from colliding with each other. They perceive the environment with sensors and prevent collisions using the data collected from the sensors.
Positive Train control is a type of automatic train protection system that prevents train-to-train collision, over speeding and unauthorized train movements. [4] It used GPS technology and wireless radio to calculate safe distances between trains to transmit movement authority from the onboard controllers on the following train, to the wayside ...
Only the provisions of ERTMS Regional should be used for train protection / collision avoidance. The central element of ERTMS Regional is the specification on the Train Control Center (TCC). This computer system takes over the functionality of Interlocking, ETCS Radio Block Center (RBC) as well as automatic planning and track management.
Wabtec is working with the Alaska Railroad to develop a collision-avoidance, Vital PTC system, for use on their locomotives. The system is designed to prevent train-to-train collisions, enforce speed limits, and protect roadway workers and equipment.

Collision avoidance systems range from widespread systems mandatory in some countries, such as autonomous emergency braking (AEB) in the EU, agreements between carmakers and safety officials to make crash avoidance systems eventually standard, such as in the United States, [7] to research projects including some manufacturer specific devices.
