In summary:
This incident demonstrates the importance of:
• signallers ensuring that the route is and will remain safe for the passage of trains, when authorising a train to pass a signal at danger
• signallers placing level crossings controlled by the signal box in full manual control, when authorising a train to pass a protecting signal at danger
• signallers stopping and thinking before trying to recover from an unexpected event as there might be pitfalls in what seems to be an obvious course of action
• drivers actively monitoring the safety of the line ahead of their train after having been authorised to pass a signal at danger
