A search warrant authorises the rail safety officer executing the warrant, in addition to the seizure of any thing of the kind described in the warrant, to seize any thing which is not of the kind described in the warrant, if –

(a) the rail safety officer believes, on reasonable grounds, that the thing –

(i) is of a kind which could have been included in a search warrant; or

(ii) will afford evidence of the commission of an offence against the rail safety law; and

(b) in the case of seizure, the rail safety officer believes, on reasonable grounds, that it is necessary to seize that thing in order to prevent its concealment, loss or destruction or its use in the commission of an offence against the rail safety law.
