The recent train derailment accidents in India has left countless shocked and many scarred for life. These fatal occurrences suggest that a single faulty or fractured track can result in mass destruction.
Regular monitoring and timely replacement of old technologies with those of new and suitable ones can help in preventing accidents. Here are some anti-collision technologies that can strengthen the possibility of reducing rail accidents and significantly improve the overall safety of passengers.
Signaling systems can be installed at the front of locomotives to avert obstacles which could cause derailment of a train due to any reason. These systems are very useful at night time or during extreme weather conditions.
Terrain imaging for diesel drivers, infrared enhanced optical and radar assisted systems use infra-red and radar technology to display information of physical obstructions ahead on the tracks for 2-3 km. This can inform the driver in advance so that they can take the necessary measures for safety and protection.
Advanced technologies such as the Tri-NETRA can predict and prevent mishaps. It would be great if the railways can expedite its efforts to invest in the advanced technologies and avert any accidents.
Technology called positive train control (PTC), which uses digital radio communications, global positioning satellites and fixed trackside signal systems to track trains’ speed and location in real time, can prevent all the tragedies. PTC can stop train-to-train collisions, prevent trains from going too fast and keep a train from moving in the wrong direction.
