Contents:- Introduction - Working of An ACD ACD An overview Salient features – what can do ACD ACD Network can not prevent a train collision when why we need Anti-Collision device (ACD ACD Network’ ( Raksha Kavach ) –Technology ACD Network – Implementation Plan Types of Anti-collision device (ACD) ACD Project commissioned in Indian Railway Anti-collision device(ACD) in locomotive ACD unit at manned LC Gate Future scope Conclusions References

3. Introduction:- The ACD Network is a train-collision prevention system is invented by “ Rajaram bojji ” and patented by the konkan railway corporation limited. ACD is rely on GPS satellites for position updates. They exchange information through radio frequency transmissions to automatically brake and prevents collisions. When installed on locomotives (along with an auto braking unit –ABU),stations and level -crossing gates (both manned and unmanned ) the network of ACD systems prevents high speed collisions in mid –sections, stations area and at level-crossing gates , thereby saving the lives of rail passengers and others users .

4. Why we need Anti-Collision device (ACD):- August 1999, Head-on Collision at ‘ Gaisal ’ –300 dead December 2000, Sarai Banjara rail disaster - 46 dead January 2003, Ghatnandur train crash - 18 dead June 2004, Karanjadi train crash - 20 dead

5. Working of An ACD:- Receive inputs from satellites , communicate with each other using radio modems & use intelligence to act to prevent Dangerous collisions

6. Salient features – what can do ACD:- Detection & prevention of Head on , Rear end and side collisions a unique feature even when a train is not protected by a signal, as in a block section . Train approach warning for road users at level crossing both manned and unmanned in addition at manned non-interlocking level crossing’, reducing the train speed to 30kmph .

7. ACD Network – Implementation Plan:- Manufacturing and Installation of ACDs with accessories. Make individual Commission for ACD installations. Training of Personnel. Post warranty Annual Maintenance.

8. Types of Anti-collision device (ACD):- Mainly Anti-collision device is divide in two parts :- (1) fixed ACDs:- Station ACD, Level Crossing ACD, Loco shed ACD etc. (2) Mobile ACDs:- Loco ACD , Guard ACD, ‏ Guard ACD etc. ‏

9. Anti-collision device(ACD) in locomotive:-

10. ACD unit at manned LC Gate:-

11. Future scope:- The idea of incorporating radar systems into vehicles to improve road traffic safety. Such systems are now reaching the market as recent advances in technology have allowed the signal processing requirements and the high angular resolution requirements from physically small antennas to be realized. Automotive radar systems have the potential for a number of different applications anti-collision devices. The problem with this brand of cars is that they are so expensive. This becomes an even bigger challenge for decrease the cost of this device.

12. Conclusions:- Indian railway is world’s second largest railway with 6853 stations , 63028 kilometers of track 37840 passengers coaches annually it carries 4.38 billion. Passengers . And all human being safety is a major duty of govt. of india At Level crossings too – ‘ACD Network’ provides the ‘TRAIN APPROACH’ warning to Road users and regulates the train speed ‘automatically’ if Loco ACD receives ‘Gate Open’ message from Gate ACD of a ‘Non-interlocked’ Manned LC gate.
