Infrastructure asset integrity
The integrity of infrastructure assets is the responsibility of infrastructure managers (IM) and the relevant parts of the supply chain. Cross-industry collaboration on matters related to infrastructure asset risk had been assigned to the Train Accident Risk Group (TARG) but will now be driven by the Asset Integrity Group (AIG).
Over the past 12 months, infrastructure failures have accounted for 12% of all modelled train accident risk, with earthworks failures carrying most of the risk within this category. The increase in earthwork failure risk is due to a significant increase in the number of embankment and cutting failures in 2019/2020, compared to recent years. Power outages and bridge scour incidents have impacted services. The industry has established a cross-industry Asset Integrity Group to work on the challenges laid out in LHSBR. It will liaise with the RSSB-facilitated system interface committees (SIC), as well as other relevant committees, including the Train Protection Strategy Group (PTSG) and the Train Accident Risk Group (TARG).
What the rail industry is doing
Ongoing assurance activities are complemented by an increasing focus on collaborative activity in risk management across the industry. This is achieved by taking whole-system and whole-life-cycle perspectives, building on existing expertise and experience.
Strategic challenges – what industry wants to do
- Promote consistent understanding of key safety requirements of an integrated operational system.
- Collaborate across supply chain, reducing risks from failure and subsequent impact on interfacing systems and subsystems.
- Strengthen understanding and application of processes for providing safety assurance, including at interfaces.
- Support collaboration at route and regional levels, including for the recording and reporting of safety and performance data.
At RSSB we provide the workspaces for collaboration across the industry so rail can get at the right data and insights, and so make good decisions about how to monitor and improve safety, health and wellbeing.
How to get involved
There are many opportunities for you to contribute to leading health and safety on Britain’s railways.
- Industry is particularly encouraged to work with, or join, the Asset Integrity Group (AIG). It will become the group to oversee the development of this area, and the cross-industry group dedicated to leading collaborative activity on the topic.
- As of June 2020, a workplan is being developed.
- RSSB publishes the Precursor Indicator Model each reporting period. This includes data driven indications of how the train accident risk associated with track, earthworks signalling, and structures might be changing.
