OREANDA-NEWS. August 17, 2011. Anti Collision Device (ACD) is an indigenously developed product of Kokan Railway Corporation Limited (KRCL). Although, the concept of ACD can meet the safety requirement of Indian Railways, the same needs to be delivered duly validated under all type of working conditions on Railways such as single lines, double lines, multiple lines, electrified routes, absolute and automatic signaling section etc. While system was installed on Northeast Frontier Railway (NFR) in non-electrified territory and on single/double line section, tests/trials and validation and certification, thereof, under other conditions as above is in progress, reported the press-centre of Indian Railways.

Deployment of ACD after initial trials was done on NF Railway. This was a single/double line non electrified broad gauge section. Based on the experience of the NF Railways, to improve reliability and dependability of ACDs and to test its functioning on multiple lines as well as electrified routes, the specification and design configuration were revised and the system as evolved was tried on the electrified multiple lines automatic signaling section of the Southern Railway in 2010-11. Operational and technical problems noticed in Sothern Railway trials are being looked into and a new ACD version-II after successful validation and certification will be deployed on NF Railway.

The ACD works have been sanctioned on Northeast Frontier, Eastern, East Central, East Coast, South Eastern, Southern, South Central and South Western Railway covering 8486 route kilometers to expedite implementation of ACD version II, subsequent to successful validation and certification and deployment of improved ACD version II of NF Railway with acceptable performance as per defined parameters. The system is planned to be progressively provided on other Railways after this.
