This guideline is produced by RISSB in conjunction with representatives of the rail industry.

The purpose of this guideline is to provide guidance that supports the application of AS 7450 Rail Systems Interoperability and AS 7666 Train Protection and Control (TPC) Interoperability standards.

As with AS 7450 and AS 7666, the aim of this guideline is therefore also to encourage rail organisations to work collaboratively towards interoperability, providing benefits for the whole of the rail industry.
