Interoperability is considered a vital requirement for rail systems in many parts of the world. In Australia, particularly, interoperability is needed to enable the safe and efficient movement of freight and passengers across the nation’s rail networks. Standard AS7450, which this document supports, provides the Australian rail industry with a process for addressing the interoperability of current and future systems, assets or processes.

Train Protection and Control (TPC) systems are an essential enabler for the safe and efficient movement of trains between networks. TPC systems which fail to support the required level of interoperability can be a barrier to achieving the required operational outcomes. The appropriate consideration in the specification, design, operation and management of TPC systems is therefore crucial to achieving interoperability.

This standard provides guidance to the Australian Rail Industry on the implementation of AS7450 to TPC systems. For the purposes of this standard TPC systems are defined as including the equipment, operating rules, engineering and management processes which combine to ensure the safe, efficient movement of freight and passengers.

For the purposes of this standard all clauses containing the term “shall” are considered mandatory requirements, all clauses containing the term “should” are considered recommendations, and all other clauses are explanatory statements.
