A cancellation message is sent when the train does not, or will not, complete its scheduled journey.

A train may be cancelled in one of three ways:

  • At activation time ("ON CALL"), usually where the applicable schedule has a STP indicator of "C" - see Planned Cancellations. Trains may be cancelled for other reasons before train has been activated, and when activation occurs, the train will be immediately cancelled with the appropriate reason code
  • At the train's planned origin ("AT ORIGIN")
  • En-route ("EN ROUTE")
  • Off-route ("OUT OF PLAN")

As with all other messages, cancellation messages will only be received for train schedules which have already been activated.
