Train patronage dataset provides Opal Train Trips by month, operator, contract area and card type. An Opal trip is where an Opal card is used to tap-on and tap-off, including where a single tap-on or tap-off is recorded. All other travel is not included.

Peak Train Load Survey 2016 provides estimates of train loads during the AM and PM peak periods - derived from a survey held on Tuesdays, Wednesdays and Thursdays from 1 March 2016 to 17 March 2016. Since the introduction of Opal, this has been replaced by Peak Train Load Estimates from 2017 using the Rail Opal Assignment Model (ROAM).

Peak Train Estimates use data extracted from the Rail Opal Assignment Model (ROAM). This model assigns Opal journeys to services based on the rail daily working timetable and train punctuality data. The customer load is aggregated to train services and assigned to rail lines.

Train station entries and exits dataset is based on the average of three day sample, representing 'a typical day' of customer entries and exits at each train station.
