The data is actual delay from scheduled departure time, in minutes.
These plots allow a prediction of the probability (on the vertical axis) of
departing d minutes or more late. The blue circle represents the
target of 82.8% of trains departing within 5 minutes of schedule; that is,
less than 17.2% delayed 6 or more minutes. If the red curve is under the
blue circle, the target is met. The green vertical line denotes the average
delay. Cancelled trains are ignored in these plots.
