5.  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

6. Consists of
 1. Automatic Train Protection (ATP)
2. Automatic Train Supervision (ATS)
3. Automatic Train Operation (ATO)

7. Does not indicate
 speed to go, distance to go, exact
location of the train, gradient of track in
ahead, position of door
opening/closing of coach.
 Visibility depends on curvature &
weather.
 No control on driver’s mistake.
 Higher margin in speed, distance
between two trains to be kept.
 No optimum utilisation of system.
 Results in lesser safety & headway.

8.  Auto Route setting, Auto train
separation, (ASM’s duty).
 Cab signaling, broken rail detection,Indicates
permitted speed.
 Auto start, Over speed protection, Auto
stop, Auto coasting, stops train if door
opens, over speed alarm, (Driver’s duty)
 Passenger Safety by door opening /
closing, Emergency stop(Guard’s duty)

9.  Traffic micro-regulation, Time Table
Generation(Control Office Job)
 Passenger information display (Commercial
Job).
 Maintenance monitoring, Crew
performance Monitoring (Managerial Job)

10. It is not only a Signaling System
It is an integrated train control
system.

11.  Operation Control Center (OCC).
 Communication Channel from OCC to way
side ATP sub-system.
 Way Side ATP System (at stations).
 On Board ATP equipment (on train).
 Track to Train communication-AFTC(track
side)
 Solid State Interlocking (SSI)

12. ◦ Cab Signalling
◦ Track Related Speed Profile generation based on line data
and train data continuously along the track
◦ Continuous monitoring of braking curve with respect to a
defined target point
◦ Monitoring of maximum permitted speed on the line and
speed restrictions in force
◦ Detection of over-speed with audio visual warning and
application 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 when
train comes to a stop

14. Coded Audio Frequency Track Circuit
 Detects train occupation on track.
 Transmission of message to give advance
information about status of
track, points, route, signals, block, headway
regulation, platform side, stoppage . . .

15.  Ensures train location based on odometer and
trackside beacons.
 Emergency braking control.
 Receives information from WS-ATP about
section ahead.
 Door opening authorization.
 Controls train motion, departure order,event
logging, maintenance monitoring, …..

18.  On screen movement

19.  To be fully operational ATP system needs:
 -1-To receive Information from ATC
trackside equipment,
 This operation can be performed by two ways :
 stationary initialisation
 moving initialisation
 -2-To calibrate the odometer

20. 1. ATO or Auto
 Only on Metro Corridor
2. 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 ATP
4. RM (Restricted Manual)
 In Depot
 Max. Speed will be limited to 25 kmph by ATP
5. Cut Out Mode
 On complete failure of ATP Equipment
 Max. Speed will be limited to 25 kmph by Rolling Stock

21. :

22.  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 by
ATP system
 Energy monitoring

23. 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

24.  Track circuit failed
 This mode is used for passing a zone that has NO transmission
of
 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

25.  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

26. It is a Major Computer Network System with
multi discipline users.
 Protect from Password - unauthorized
person must not modify any parameter.
 Needs Sincere maintenance.
 Protect from virus.
 Skilled Maintenance staff.
 Thorough testing before commissioning.

29. THANK YOU ALL…
