2. Line 1 (Rail Corridor), 22 Km in Length Elevated/ Surface Shahdara Rithala R1 Section Shahdara Tis Hazari R2 Section Tis Hazari Tri Nagar R3 Section Tri Nagar Rithala Line 2 (Metro Corridor), 11 Km in Length Underground Vishava Vidayalaya Central Secretariat M1 Section Vishava Vidayalaya Kashmere Gate M2 Section Kashmere Gate Central Secretariat 3. Line 3 (East West Corridor) Mostly Elevated 23 Km in Length Indraprath Dwarka 4. Computer Based Interlocking Continuous Automatic Train Control (CATC) Automatic Train Protection (ATP) Distance to Go with Track to Train communication through Coded AFTC with Cab Signalling Automatic Train Supervision (ATS) Automatic Route Setting; Automatic train Regulation Centralized control from Operational Control Centre Automatic Train Operation (ATO) For Metro corridor only 5. Consists of 1. Automatic Train Protection (ATP)2. Automatic Train Supervision (ATS)3. Automatic Train Operation (ATO) 6. Does not indicatespeed to go, distance to go, exactlocation of the train, gradient of track inahead, position of dooropening/closing of coach. Visibility depends on curvature &weather. No control on drivers mistake.Higher margin in speed, distancebetween two trains to be kept. No optimum utilisation of system. Results in lesser safety & headway. 7. Auto Route setting, Auto trainseparation, (ASMs duty). Cab signaling, broken rail detection,Indicatespermitted speed. Auto start, Over speed protection, Autostop, Auto coasting, stops train if dooropens, over speed alarm, (Drivers duty) Passenger Safety by door opening /closing, Emergency stop(Guards duty) 8. Traffic micro-regulation, Time TableGeneration(Control Office Job) Passenger information display (CommercialJob). Maintenance monitoring, Crewperformance Monitoring (Managerial Job) 9. It is not only a Signaling SystemIt is an integrated train controlsystem. 10. Operation Control Center (OCC). Communication Channel from OCC to wayside ATP sub-system. Way Side ATP System (at stations). On Board ATP equipment (on train). Track to Train communication-AFTC(trackside) Solid State Interlocking (SSI) 11. Cab Signalling Track Related Speed Profile generation based on line dataand train data continuously along the track Continuous monitoring of braking curve with respect to adefined target point Monitoring of maximum permitted speed on the line andspeed restrictions in force Detection of over-speed with audio visual warning andapplication of brakes, if necessary Maintaining safety distance between trains Monitoring of stopping point Monitoring of Direction of Travel and Rollback Releasing doors on the correct side of the platform whentrain comes to a stop 12.

Transmission of message to give advanceinformation about status oftrack, points, route, signals, block, headwayregulation, platform side, stoppage . . . 14. Ensures train location based on odometer andtrackside beacons. Emergency braking control. Receives information from WS-ATP aboutsection ahead. Door opening authorization.

To be fully operational ATP system needs: -1-To receive Information from ATCtrackside equipment, This operation can be performed by two ways : stationary initialisation moving initialisation -2-To calibrate the odometer 19. 1. ATO or Auto Only on Metro Corridor2. ATP or SM (Supervised Manual) or MCS (Manual Cab Signal)3. ROS (Running On Sight) On failure of ATP mode Max. Speed will be limited to 25 kmph by ATP4. RM (Restricted Manual) In Depot Max. Speed will be limited to 25 kmph by ATP5. Cut Out Mode On complete failure of ATP Equipment Max. Speed will be limited to 25 kmph by Rolling Stock 20. : 21. ATP Ensures: In MCS Mode : The Total energy of the train can be absorbed by the braking force In ROS Mode :This function is not performed byATP system Energy monitoring 22. ROS (Running on sight )supervision: ATP Ensures that: In ROS Mode: Maximum train speed is 25 Kph AT Position of mode selector is SM (ATP) As soon as the train speed is higher than the maximum authorised speed, the EB is triggered 23. Track circuit failed This mode is used for passing a zone that has NO transmissionof cab signal information (failure situation) Train is stopped in front of a restrictive ATP limit ROS is activated by an aware action of the driver, by pressing the ROS push-button after authorisation, Note : Mode selector has first to be switched out of ATP and back. If the localisation is not lost, as soon as the train is on an operating track circuit, the MCS driving mode is automatically activated 24. Cab signal Proceed is given by MCS mode : Target speed is non zero Supervision indicator is Green Target speed includes speed restrictions Stopping positions are given by marker boards Note on signals : Line signal can be Green, Blue , Blank will be no cab signal proceed with red signal 25. It is a Major Computer Network System withmulti discipline users. Protect from Password - unauthorizedperson must not modify any parameter. Needs Sincere maintenance. Protect from virus. Skilled Maintenance staff. Thorough testing before commissioning. 26. THANK YOU ALL
