The objective of this Australian Standard is to provide the railway industry with guidance including a framework and process for planning and implementing any change to a TPC system where the change has potential to impact interoperability. In particular, this Standard will support the introduction of next generation train protection and control technologies such as in-cab signalling, which have been rolled out across rail networks within Australia.

This Standard provides requirements and guidance to the Australian rail industry on the implementation of AS 7450 to train protection and control (TPC) systems.
This Standard is intended to be applied by rail transport organizations (RTOs) when implementing a new, or changes to, TPC systems.
