A method of method of monitoring vandalism, trespassing or theft at railside locations is disclosed. The method comprises the steps of:a) providing an acoustic transducer comprising a sensing fibre optic cable proximate the railway for picking up acoustic signals;b) receiving acoustic signals from the transducer;c) analysing the received signals to determine whether the noise expected to be created by an item has disappeared from the received signal, whether an abnormal signal has been received and/or whether signals from items not associated with the railway have been received.
