It provides a framework for managing change that is consistent with AS 7717 and AS 7718. This Standard is intended to be used by rail infrastructure managers, rail operators and suppliers of railway systems.The scope of this Standard includes:(a) managing multiple changes on the one set of train control system infrastructure;(b) Safeworking system selection;(c) operational and technical requirements for changes and documenting operational performance of train control systems;(d) testing requirements for different levels of changes;
