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 is driven by the Asset Integrity Group (AIG). The AIG has been established 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(TPSG) and the Train Accident Risk Group (TARG).
