79.—(1) Where the Commission considers that the risk to the safety of persons is so serious that the operations of a railway or of particular railway infrastructure or services, or activities carried out by, or omissions of, any other person which may pose a danger to persons operating or using the railway, should be restricted or should be immediately prohibited until specified measures have been taken to reduce the risk to a reasonable level, the Commission may apply, ex parte, to the High Court for an order restricting or prohibiting such operation.

(2) The Court may make such interim or interlocutory order as it considers appropriate.

(3) Any such order shall have effect notwithstanding the terms of any permission given under this Act or any other enactment for the operation of the railway or part thereof or, where the order refers to an other person, the carrying out of an activity by such person.

(4) On any application for the revocation or variation of an order made under subsection (1), the Commission shall be entitled to appear, be heard and adduce evidence.
