The Sunday-evening collision of two passenger trains near Vizianagaram of Andhra Pradesh could have been prevented had the indigenous ‘Kavach’ or Train Collision Avoidance System (TCAS) been installed in both the trains as it is meant to prevent precisely such incidents (when two trains enter the same line), senior railway officials said on Monday.
But, ‘Kavach’ is currently under implementation in South Central Railway (SCR) only to an extent of 1,200 km and the equipment has been installed in only 140 locomotives and at 110 stations in the zone so far. It is yet to be taken up in other zones though tender process is on, they said.
