The Train Collision Avoidance System (TCAS) is being developed locally by Research Designs and Standards Organization (RDSO) in partnership with Indian Vendors. This safety system aims to provide the ability to prevent train accidents caused due to the error of the signal driver passing in danger (SPAD) or speeding.
After the successful trials of Proof of Concept, limited field trials have been conducted with equipment from several suppliers. In addition, extensive TCAS field trials have been conducted in the Lingampalli-Vikarabad-Wadi-Bidar pilot section (250 RKms) of the Secunderabad division of the South Central Railway. Trials on two pairs of passenger trains have begun in the pilot section.
All railway employees in the safety category receive structured training according to the periodicity prescribed at various stages of their career. They also undergo mandatory update programs. The detailed modules that give the periodicity and the course content taking into account technological changes and operational requirements are available. Emphasis is placed on practical training which helps to assimilate technology transfer and upgrading skills. Security category personnel also receive training in disaster management.
The ACD network is a train collision prevention system invented by Rajaram Bojji and patented by Konkan Railway Corporation Limited, a public company of the Ministry of Railways, Government of India. ACDs are based on GPS satellites for position updates. They exchange information through radio frequency transmissions to automatically brake and prevent collisions.
Loco ACDs brake to reduce the train speed to 15 km / h if in focus. They receive messages from each of the ACDs on adjacent tracks. If the incoming ACDs of other trains are read as "separate trains", the trains are decelerated until they have stopped to avoid dangerous side collisions that may occur when adjacent tracks have been damaged. The use of experimental trials of ACD in the Southern Railway has been successful.
