View source for 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 does not apply on 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.
