Planned Cancellations

Overview

Planned cancellations are schedule records with an STP indicator of "C" which are overlaid on WTT schedules. They contain no calling points, and they indicate a schedule is not valid for a particular day.

The difference between a planned cancellation and an operational cancellation is subtle, but important:

  • An operational cancellation is reactive - a train was due to run to this schedule, but was cancelled for an operational reason, e.g. service disruption
  • A planned cancellation is not reactive - the schedule that would apply on a particular date is overridden, for example, on a public holiday

Activations for CAN schedules

Planned cancellations will be activated by a Train Activation message as normal, but immediately cancelled with a Train Cancellation message with a 'PD' - Planned Cancellation - causation code. For the purposes of tracking real-time trains, these can be ignored.
