## 2771. SHRI JAYADEV GALLA:

Will the Minister of RAILWAYS be pleased to state:

- (a) whether  Indian  Railways'  signalling  system  can  be  compared  with other signalling systems in advanced countries;
- (b) if so, the extent to which 'Indian Railways' signalling system can be made better than the European Train Controlling System;
- (c) whether  it  is  true  that  a  pilot  project  has  been  started  to  test  the above system;
- (d) if so, the details thereof;
- (e) the details of how ETCS Level-2 is different from Level-1; and
- (f) the expenditure involved to implement ETCS Level-2 in the entire rail network of the country and the manner in which Railways is going to pool the resources for the same?

## ANSWER

## MINISTER OF RAILWAYS AND COMMERCE & INDUSTRY

## (SHRI PIYUSH GOYAL)

systems  suitable  for  speed  up  to  110  KMPH  except  for  few  sections suitable for 130 KMPH and Hajrat Nizamuddin - Agra section suitable for speed up to 160 KMPH. In advanced countries, majority of networks are provided  with  Signalling  Systems  for  speed  up  to  250  KMPH  to  300 KMPH.

With  the  increasing  demand  for  raising  of  speed  of  trains,  along  with more  trains  on  existing  network  and  to  enhance  Safety,  additional Modern Signalling systems are required on Indian Railways.

To match with the above requirements, additional signalling system are proposed to be provided as under,

- (i) Automatic Train Protection (ATP) Systems.
- (ii) Mobile Train Radio Communication (MTRC) Systems.
- (iii) Remote Diagnostic & Predictive Maintenance systems.
- (iv) Centralised Traffic Control (CTC)/Train Management Systems (TMS).
- (c) Yes, Sir.
- (d) Pilot  projects  on  four  Sections  of  lengths  between  145  RKMs  to  170 RKMs each, totalling 640 RKMs on Golden Quadrilateral and Diagonal routes have been taken up for trials of Modern Train Control System, as under:

- (i) Nagpur - Badnera

-       175 KMs.

- (ii) Renigunta - Yerraguntalla   -

165 KMs.

- (iii) Vijainagram - Palasa

-       145 KMs.

- (iv) Bina - Jhansi -

155 KMs.

- (e) In ETCS level-1 system, the updation of Movement Authority (permitted distance to travel by train) in the Loco is intermittent i.e. when  the  Loco  negotiates  a  Signal,  the  Movement  Authority  is updated as per aspect of the Signal.  In case of ETCS level-2 system, the  updation  of  Movement  Authority  is  continuous,  as  movement authority to Loco is transmitted through a Radio System.  In case of ETCS  Level-1, physical Signals are an essentially requirement. Whereas  in  case  of  ETCS  level-2  system,  physical  signals  are  not essential.
- (f) The  expenditure  involved  to  implement  a  system  equivalent  or comparable  to  ETCS  level-2  and  other  associated  systems  in  the entire rail network of the country shall be ₹ 77,912 Cr.  The Ministry is working on suitable mechanism for pooling resources for implementation of this system on entire rail network.
