This Standard establishes general principles for railway infrastructure managers to manage clearances throughout the asset lifecycle, specifies a system for calculating appropriate clearances, and provides recommended dimensions.
This Standard excludes:
(a) temporary structures such as formwork and scaffolding covered by special operating conditions;
(b) vegetation control;
(c) expendable rolling stock items covered in AS 7507; and
(d) tram tracks, cane railways, and monorail networks.
The objective of this Standard is to manage the risks to safety arising from the interface between rail infrastructure and rolling stock during railway operations. It achieves this by setting out the minimum clearance standards for safe operation between:
(a) rolling stock (including loads) and trackside structures and equipment; and
(b) rolling stock (including loads) on adjacent tracks.
This Standard uses key inputs from AS 7507.
