Close Call

A Close Call is defined as anything that is likely to cause harm or damage.

This includes the potential to:

  • Harm a person including minor, major injuries, and fatalities
  • Harm the environment and/or protected species
  • Damage railway infrastructure, plant, vehicles, tools, equipment, systems and information

What’s the difference between a Close Call and an incident?

A Close Call is something that is likely to happen, whereas an incident has already taken place.

For example, if a trip hazard is spotted it can be reported as a Close Call because someone could trip over it. If someone actually trips because of the hazard, it is then classed as an incident.

What to do if you see a Close Call

Safety is everyone’s responsibility, if you see something that could cause harm or damage follow these three steps:

  • Recognise – Could it cause harm or damage?
  • Respond – What can you do?
    • Fix the situation, if you can do so safely – then report it
    • Always challenge unsafe behaviour – then report it
    • Inform others around you so they are aware of any risk.
  • Report – Always report Close Calls





Reporting a Close Call 

Reporting Close Calls means that we can remove immediate risks and understand strategically where we need to make improvements by identifying areas of high risk and taking steps to prevent more serious incidents from occurring.

All Close Calls under Network Rail’s area of responsibility, along with Close Calls bulk uploaded by Principal Contractors and Suppliers, will make their way to the Close Call System for industry analysis.

To ensure that timely action is taken to address any risks identified, the first step is to decide which is the most appropriate channel for you to report your Close Call.

Please note from 27 Feb 2024, the Close Call Telephone Helpdesk will no longer operate.

Please see below for the options available.
