STATEMENT  REFERRED  TO  IN  REPLY  TO  PARTS  (a)  TO  (c)  OF MANSUKHBHAI DHANJIBHAI  VASAVA  AND  SHRI  CHHATAR  SINGH  DARBAR  TO  BE ANSWERED IN LOK SABHA ON 04.12.2019 REGARDING ASSESSMENT

UNSTARRED QUESTION NO. 2712 BY SHRI OF ANTI-COLLISION DEVICES

(a) :  Yes, Sir.

- (b) & (c):   Safety is accorded the highest priority by Indian Railways and all possible steps are undertaken on continuous basis to prevent accidents  and  to  enhance  safety.    Various  technological  devices  for safety and their present status are as under:-
-  Anti Collision Device (ACD) developed by Konkan Railway Corporation Limited (KRCL) was provided as a pilot project on 1736 Route km on Northeast Frontier Railway (NFR). Complex operational and technical problems were experienced during these trials, which could not be fully resolved by KRCL due to design limitation of ACD. As such, proliferation of ACD has not been undertaken.  Presently following  different  Automatic  Train  Protection  (ATP)  systems  are existing on Indian Railways:
- i. Automatic Train Protection (ATP) System called Train Protection  and  Warning  System  (TPWS)  based  on  European Train  Control  System  Level-1  (ETCS  L-1)  Technology  has been  implemented  on  345  Route  km  (200  Route  km  DelhiAgra Section, 117 Route km Chennai Suburban section and 28 Route km of Metro Railway Kolkata).
- ii. An  earlier  version  of  ATP  system  called  Auxiliary  Warning System (AWS) is presently functional on 413 Route km in the Mumbai suburban section of Central Railway (289 Route km) and Western Railway (124 Route km).
- iii. Train  Collision  Avoidance  System  (TCAS)  is  an  indigenous Automatic Train Protection (ATP) System being developed by Indian Railways in association with 3 Indian manufacturers. The system has been installed on Lingampalli - Vikarabad Wadi and  Vikarabad - Bidar section (250 Route km) on South Central Railway. Product of all the 3 Indian Manufactures has been approved for developmental orders for speeds up to 110 kmph in Absolute Block Signalling section.
- iv. An  ATP  system  based  on  European  Train  Control  System Level-2  (ETCS  L-2)  is  being  implemented/planned  on  Indian Railways as under:
-  Provision of ETCS L-2 System on 4 sections on Nagpur Badnera, Jhansi -Bina, Yerraguntla -Renigunta & Vizianagaram - Palasa sections totaling to 640 Route km.
-  In  connection  with  works  of  raising  of  speed  up  to  160 kmph, ETCS L-2 system is proposed to be implemented on Delhi - Mumbai and Delhi - Howrah sections.
-  Electrical/Electronic  Interlocking  System.    Provision  of  modern signaling also improves through put and line capacity.  By quicker

operation  of  signaling  gears,  the  operation  time  is  reduced  and trains can be dealt one after another quickly. Centralized Electronic/Electrical Interlocking Systems, Centralized operation of points and signals are being provided by replacing old mechanical lever frame systems.  These systems have been provided at 5974 stations up to 31.10.2019.

-  Track  Circuiting  of  stations  to  enhance  safety  for  verification  of track occupancy by electrical means instead of human element is completed at about 6118 stations upto 31.10.2019.
-  Block  Proving  by  Axle  Counter(BPAC)  Hitherto,  complete  train arrival was informed by Guard to the Station staff after which only, line clear for the next train could be granted. This loses significant time in the train operation.  In order to reduce this time loss, Axle Counters  for  automatic  clearance  of  block  section  (BPAC)  are being provided for ensuring complete  arrival of train before granting of line clearance for next train.  BPAC has been provided at 5509 block sections up to 31.10.2019.
-  Interlocking of Level Crossing Gates to protect Level Crossing Gate with signals to avoid accidents have been done at 11497 gates up to 31.10.2019.
- 
- Vigilance Control Devices (VCD).   Vigilance Control Devices (VCD) are being provided on electric locomotives to ensure safety.  As it
- is a safety device, its effectiveness is checked regularly.  VCD is a device  which  takes  intermittent  inputs  through  positive  actions from the driver like sounding of horn, operation of master controller, application of brakes and pressing of button to judge his alertness  every 60  seconds  and applies brakes if found lacking to stop  train  thereby  ensuring  safety.    All  Electric  locomotives  are equipped with VCD to ensure safety.
-  Wheel  Impact  Load  Detectors  (WILDs)  have  been  installed  at various  locations  to  identify  defective  wheels  &  bearings  and provide Alerts to get it rectified in time by taking corrective action so that accidents may be avoided. Comparative better results have been received.
-  Online  Monitoring  of  Rolling  Stocks  (OMRSs)  having  WILD  and Acoustic  Bearing  Defect  detection  functionalities  also  have  been installed for prevention of accidents by providing Online monitoring of  Rolling  stock  and  their  efficacy  is  still  being  observed.    17 Numbers  of.  Wheel  Impact  load  detectors  (WILD)  have  been installed  over  Indian  Railways  during  2006-2018,  And  09  Online
- Monitoring  of  Rolling  Stock  (OMRSs)  have  been  installed  during 2017-19.
-  Fog Pass Device: Fog PASS Devices have been provided to working crew in fog prone areas. This is portable equipment issued to Loco Pilots  while  working trains during fog season, which guides Loco Pilot about incoming signal location.
-  Diesel  Locomotives  are  provided  with  Vigilance  Control  Devices (VCD) for checking alertness of Loco Pilots.
-  Remote  Monitoring  and  Management  of  Locomotives  and  Trains (REMMLOT) -this enables remote monitoring of Diesel Locomotives. This enable focused counseling and training of crew mainly who are prone to unsafe working. REMMLOT also monitors condition of locomotive and facilitates preventive maintenance of locomotives.
