Anti-collision facelift for 5,160 km of rail route
A new version of the Anti-Collision Devices (ACD) will soon be implemented over the sanctioned 5,160 route km of railway network. The new version, also called Train Collision Avoidance System (TCAS), replaces the old ACD design after operational and technical problems were noticed during trials conducted in the Southern Railway.
“These operational and technical problems are being looked into and a new ACD Version-II after successful validation and certification will undergo extensive conformity trials once again before implementation,” Minister of State for Railways Bharatsinh Solanki told Parliament on Friday.
ACD works have been sanctioned on 5,160 route kms on Eastern, South Eastern, East Central and East Coast Railways during last three years and will now be taken up for implementation with new ACD Version-II.
The initial trial for ACD was done as a pilot project covering 1,736 route kilometres and 548 locomotives on the Northeast Frontier Railway (NFR) where it has been in service trial since July 2006. This was a single/double line non-electrified Broad Gauge section.
Based on the experience of the NFR, to improve reliability and dependability of ACDs and to test its functioning on multiple lines as well as electrified routes, the specifications and design configuration were revised and the system as evolved was tried on the electrified multiple lines, automatic signalling section of the Southern Railway in 2010-2011.
