(1) A rail transport operator must:
(a) so far as is reasonably practicable, identify and assess risks to safety that may arise from railway operations carried out by or on behalf of the operator because of, or partly because of, railway operations carried out by or on behalf of any other rail transport operator; and
(b) determine measures to manage those risks; and
(c) for managing those risks, seek to enter into an interface agreement with the other rail transport operator or operators.
(2) Except to the extent the Regulations otherwise provide, subsection (1)(c) does not apply if none of the rail transport operators is a rail infrastructure manager.
