Some cows have broken through the boundary fence and got onto the railway line. We see how poor communications between driver and signaller, and a failure to follow correct emergency procedures, allow the situation to escalate into a serious incident.

We also take a look at the research which focuses on best practice training for drivers on routes undergoing change. We mark 175 years of the Railway Inspectorate; and feature a new approach designed to provide a deeper understanding of why SPADs happen.
