Kavach System: A type of anti-collision device was tried out on the line more than 10 years ago. But now the focus is on installing Kavach, which comes with five subsystems, is more efficient and is crucial as the speed of the trains is being increased from 110kmph to 130kmph. There is a target to increase the speed further to 160kmph. Kavach will also be installed on the Chennai Central-Gummidipoondi route and the Chennai Central-Arakkonam route, though a train protection and warning system has already been commissioned on these routes.
Kavach is a technology-intensive system that aids the loco pilot in the train running within specified speed limits by automatic application of brakes in case the Loco Pilot fails to do so and also helps the train safely run during inclement weather. Vaishnaw stated further that the KAVACH system is not resting on its laurels.
