A system comprises a video camera 10 arranged to monitor a railway node 20 (i.e. a stop, crossing or junction) and a video analytics module 30. The module receives a video stream 32 from the video camera, analyses it 34 to generate an alert signal 36 upon determining that it meets an alert condition for a predefined scenario at the railway node, and sends the alert signal to a railway control centre, a public address system or an on-board train management system. The scenario may be a road vehicle inside or approaching a junction, a pedestrian inside a junction, crossing, or dangerous area of a station (Fig.8), a pedestrian exhibiting dangerous behaviour or in distress, or an overcrowded station. The video analytics module may include a classifier to identify an object of interest, a tracker to track its location and movement and a trip wire detector to generate the alert signal if it passes a mapped safety boundary.
