Definition

Freight sector scorecard

Any derailment of a train or rail vehicle, including a derailment that occurs: 

  • While the line is blocked due to a previous accident or emergency.
  • Occurring within a possession, including worksites within a possession.
  • Occurring during a shunting operation, where the wheel of the vehicle has contacted the ground. E.g. a freight vehicle lifted by a crane or magnet and then placed back onto the rail head is NOT a derailment.

Notes


  • Railway Undertaking (RU) should never be the event owner for derailments which occur on or affecting a running line managed by Network Rail (NR). NR as the Infrastructure Manager (IM) will enter the event in SMIS.
  • If you are unclear as to who manages the infrastructure (e.g. a derailment occurring on a customer site), guidance should be sought from the local operations team who can confirm the owner of the site. 
  • If your organisation are the Infrastructure Manager for a Yard, depot siding where a derailment occurs, your organisation as the IM should enter the derailment in SMIS.
  • If you are trying to select a Yard, Depot or Siding (YDS) location from 'What was the Yard, depot or siding area?' and the location is not available to select, please raise a ticket via the service desk and request for the location to be added to the YDS asset list (Raise SMIS asset update request).
