STATEMENT REFERRED TO IN REPLY TO PARTS (a) TO (c) OF UNSTARRED QUESTION NO. 2548 BY SHRI M.I. SHANAVAS TO BE ANSWERED IN LOK SABHA ON 03.01.2018 REGARDING ULTRA MODERN SIGNALLING SYSTEM

- (a)  to  (c)  :  Computer/Microprocessor  based  Signalling  Systems  are  being used extensively on Indian Railways. Predominantly Computer/Microprocessor based systems being used are:-
1. Electronic  Interlockings  with  centralized  operation  of  points  and signals are being provided to eliminate human failure and to replace old mechanical systems. These systems have been provided at 1256 stations over Indian Railways upto 30.11.2017.
2. Automatic Train Protection (ATP) System: -
- (i)      ATP  System  based  on  European  Train  Control  System  (ETCS) technology mitigates safety  risk  of  accidents/collisions  due  to  loco pilot's  error  of  Signal  Passing  at  Danger  or  over  speeding.  It  is  a proven European train protection technology and deployed extensively on World Railways.

European  Train  Control  system  has  been  operationalized  on  342 RKMs on Indian Railways.

- (ii)  Train  Collision  Avoidance  System  (TCAS)  is  a  developmental project being taken on a limited section (250 km) on South Central Railway.  Operational  deployment  of  TCAS  on  Railways  on  Absolute Block Signalling sections will be taken-up after successful conclusion  of  the  extended  field  trials  and  safety  certification  of system by Independent Safety Assessor (ISA).
3. Train  Detection  Device:-  To  ensure  complete  arrival  of  train  before granting  line  clear  and  to  detect  presence  of  train  in  a  station  of  axle counters  have  been  provided  15342  Numbers  of  axle  counters  on  block sections and Station sections over Indian Railways.

4. Centralized  Traffic  Control  (CTC)  in  Indian  Railways:-  A  Centralized Traffic Control (CTC) with Electronic Interlocking and automatic signalling system is being set up on the Ghaziabad-Kanpur route - one of the busiest sections of Indian Railways. This is 410 km long electrified route dealing with 200 trains per day. Its Central Traffic Control Centre is established at TUNDLA station.

CTC System will help in real time monitoring and better management of trains.  It  provides  for  remote  operation  of  signals  from  the  centralized traffic control office. The CTC system has been made operational for seven stations pilot section.

5. Train Management System (TMS):- TMS helps in real-time monitoring of trains in the control room. The arrival status of local trains is displayed on indicators installed on platforms in the form of a countdown timer (in minutes) to the train's arrival on the platform accompanied by automatic announcements on platforms.

TMS  has  been  provided  on  Mumbai  suburban  section  of  Western  and Central  Railway.  On  WR,  it  covers  section  from  Churchgate  to  Virar extending over 60 km covering 28 stations and on CR it covers suburban section  from  CST  Mumbai  to  Kalyan  extending  over  54  km  covering  26 Stations.  TMS  work  is  also  nearing  completion  at  Howrah  on  Eastern Railway.
