Introduction:
The ISA will carry out safety assessment of the Signalling & Train Control System, Platform Gates and Platform Screen Door System and the interfaces with the other systems such as Track, Rigid Overhead Contact System, Civil engineering works, Tunnel Ventilation System, Fire Safety provisions, Evacuation methodology etc.
The Works for the Signalling & Train Control system and Platform Gates & Platform Screen Doors system shall be carried out by the DS06 and DS08 contractors respectively.
Role of the ISA:
- The role of the ISA can be broadly summarised as per the following responsibilities.
- To perform independent safety assessment in accordance with the required standard (CENELEC EN 50126, CENELEC EN 50128, CENELEC EN 50129);
- To verify that the required level of safety is achieved;
- To perform independent safety assessment of “Standard Operating Procedures for normal/degraded/emergency Train Operation” for -mode of operation on main line and Depot of Line-10, in accordance with international norms/global practice/standards (IEC- 62267 & IEC- 62290).
- To give an independent third-party opinion on the safety of the system; and
- To put the Employer (DMRC) into a position to allow operations for revenue service.
The output of such assessment shall confirm that:
The Signalling & Train Control system and Platform Gates & Platform Screen Doors Systems safety requirements are completely defined;
The Signalling & Train Control system and Platform Gates & Platform Screen Doors System is compliant with all safety requirements;
All safety risks have been correctly identified, and either eliminated or reduced to an acceptable level;
The Signalling & Train Control system and Platform Gates & Platform Screen Doors System is capable of being operated and maintained to an adequate level of safety;
All necessary safety documents, in particular the various system and subsystems safety cases have been produced, assessed and approved accordingly;
All necessary “Standard Operating procedure for normal/ degraded / emergency train operation” for UTO mode of operation on main line and depot have been assessed and approved accordingly.
The Signalling & Train Control system and Platform Gates & Platform Screen Doors System are deemed fit for revenue service operations with passengers.
Project Overview:
Line-10 consists of approximately 23.8 km of elevated/Underground sections from Aerocity to Tughlakabad station. There are Fifteen (15) stations having Signalling and Train Control systems on this line and one (1) Depot at Sarita Vihar.
This Line will be opened for revenue service as per the schedule provided in DS06 Appendix V of PS. There will be provision of i-ATS (jointly developed by DMRC and BEL) in parallel with the ATS system supplied by the signalling contractor as per the interface requirements provided in the contract DS06 (refer Appendix A8 of DS06 PS).
Line-7 Extn consists of approximately 12.558 km of elevated section from Maujpur to Majlis Park station. There are eight (8) elevated stations having half height platform gate systems on this line and one (1) depot located at Mukundpur.
Line-8 Extn consists of approximately 29.26 km of elevated/underground section from Janakpuri West to R.K. Ashram station. There are Twenty-Two (22) stations out of which fifteen (15) elevated stations have half height Platform Gate & Seven (7) underground stations have full height Platform screen door system and one Depot at Mukundpur.
Line-10 consists of approximately 23.8 km elevated/underground section from Aerocity to Tughlakabad station. There are Fifteen (15) stations out of which Four (4) elevated stations have half height Platform Gate & Eleven (11) underground stations have full height Platform screen door system and one Depot at Sarita Vihar.
The Line-7 Extn, Line-8 Extn and Line-10 will be opened for revenue service as per the schedule provided in Appendix V of DS08 PS.
Scope of Works:
The Works to be executed under the contract DS06 include the design, manufacture, supply, installation, testing & commissioning and technical support for a complete, integrated Communication based Signalling & Train Control System for Line-10 (Aerocity to Tughlakabad, including i-ATS),including the supply of spares and the training of Operation and Maintenance (O&M) personnel and the contract DS08 include the design, manufacture, supply, installation, testing & commissioning of Platform Gates & Platform screen doors for Line 7 Extn (Maujpur to Majlis Park), Line 8 Extn (Janakpuri West to R K Ashram) and Line 10 (Aerocity to Tughlakabad),including the supply of spares and the training of Operation and Maintenance (O&M) personnel.
