= Forecast - what is it? =

In acumen parlance, the Forecast is a service which runs within the application with the sole purpose of aggregating numerous sources of information and extrapolating this against a train service schedule; the net result is a forecast of a train service schedule that reflects all known conditions and one which has a high degree of accuracy.

Items that acumen uses to produce the forecast are:

* Current reported position and any lateness;
* Any overdue reports;
* Activity times provided in the schedule and minimum activity times specified within Timetable Planning Rules (TPR);
* Association lateness;
* Minimum turnaround times, where relevant;
* Timetable allowances provided within the train service schedule;
* Timetabled sectional running times;
* Any replan activity.
