I have come to know from the Internet and TV News that the Automatic Block Signalling System (ABBS) which is used in railways of various foreign countries , is being used on the Mathura-New Delhi and Howrah-Asansol Sections on IR . Can anybody tell me that which other routes are using this ABSS presently and which new routes have been surveyed for their installation ?? With the no of accidents and sabotages increasing on trains , this signalling system is required on all , atleast A-Grade routes as installing Anti-Collision Device (ACD) Signalling System everywhere would be very expensive for Indian Railways . Thanks .
