Modernisation of the Danish railway signaling system
Brief
Provide support in the implementation of the signaling system safety demonstration activities, including the Interlocking (IXL), Train Control (ERTMS/ETCS) and Traffic Management (TMS) subsystems.
ERTMS/ETCS: European Rail Traffic Management System/European Train Control System
TMS: Train Management System
Project challenge
- To provide ongoing support during the development of the signalling system for all safety aspects, from the definition of the safety management process to the issuing of the Safety Case.
- Development of safety analyses (referring to system functions and interfaces) for the definition of safety requirements.
Solution
NIER contributed to:
- the definition of the safety management process;
- the development of safety analyses (System Hazard Analysis and Hazard Analysis of external and internal interfaces):
- verification of the satisfaction of the safety requirements and acquisition of the evidence necessary for system validation;
- the drafting of safety documentation, including the Generic Application Safety Case in accordance with EN50129.
Execution phases
FASE 1
Definition of the safety management process (drafting of the Safety Plan).
FASE 2
Development of the System Hazard Analysis.
FASE 3
Development of the Hazard Analysis of the interfaces.
FASE 4
Drafting of the Validation Report on the basis of the evidence provided by the verification and testing activities.
FASE 5
Drafting of the Generic Application Safety Case.
