  • Vigilance System,
  • Station Protection Systems,
  • Deadman System,
  • TPWS,
  • ATP,
  • ATMS,
    ETCS,
  • CBTC.

Operation of rolling stock is not covered.

Rolling stock used on light rail, cane railway and monorail networks are not covered.

Driverless systems are not covered.

Hazard identification:
1
5.6 Out of Control Trains
2
5.9 Signal Passed at Danger
3
5.18 Level crossing collision
4
5.20 Driver fatigue
5
5.21 Driver being distracted
6
5.22 Overspeed
7
5.23 Track failure
8
5.46 Excessive acceleration
9

10
Events that occur due to the Stabling of and Pre-Start of trains e.g. accidental on board isolation, calibration checks not done.

Benefits:

Safety risk
A common approach to the resolution of those safety hazards identified.
Standard approach to SIL rating definition, engineering design and fit for purpose testing validation.
Streamlined implementation for new operators entering the market space.
Interoperability / harmonisation
Effect interface across a variety of classes of Rolling stock, minimises the risk of stranded assets only being able to operate in special areas.
ensure interoperability and harmonisation.
Financial
Effective use of rail assets and resources
Better amortization of development costs
Aligning development requirements may reduce overall costs to the industry, reduce specification effort, and reduce acceptance times
