CONTENTS2 The ACD is a Train Collision prevention system patented by Konkan Railway Corporation Limited.ACDs have knowledge embedded intelligence It takes inputs from GPS satellite system for position updates to take decisions for timely auto-application of brakes to prevent dangerous 'collisions', thus forming a Raksha Kavach.ACDs fitted (both in Locomotive and Guard's Van of a train) act as a watchdog.Loco ACD of a train also applies brakes to reduce the train speed either to 15 km/h .INTRODUCTION3DEFINITION The anti collision device is an electronic device to ensure the safety and proper operation of the trains in order to avoid the risk of dangerous and unexpected collisions of the trains which may be caused due to human errors and equipment failures. 4

NEED OF A.C.D.

5 The ACD will automatically regulate the train's speed. It can also detect when the bogies of atrainfrom an adjacent track derail on to atrain's. The ACDs automatically apply the brakes, bringing both the trains to a halt without the intervention of the driver. It can also detect when the bogies of atrainfrom an adjacent track.

Mobile ACDs take inputs from GPS satellite system for position updates and network with track-side ACDs located within a radius of 3 kms (using UHF radio modems); to activate brake(s) with the help of on-board Loco ACDs through their automatic braking units(ABUs), whenever a collision-like situation is perceived.13Features of ACD

Anti lock braking system(ABS)-improve steer ability and hasten deceleration. Traction control system-(TCS)-improving overall vehicle control. Enhanced stability control(ESC)-prevention of de-alignment. Latest technology used.

Benefits of the ACD systemVery economical and cost effective.Easily adaptable and expandable.Less susceptible to vandalism.No cabling on the track required.No way had side equipment required, hence no requirement of power.Employs state-of-art hardware and software technology.

14It prevents collisions.It decreases the timing between two consecutive trains running one after another.Used in heavy vehicles like cranes, earthmovers etc .To prevent accidents and for their safe working in public places. Used as a tracking device.
